3.3
Hazards
3.3.1
Laser Hazards
All Warnings, including those in the Safety Notes and those in other sections of these
Instructions for Use, must be heeded.
Laser emissions from the housing of the Laser and the conduit of the beam delivery optic are
less than the AEL for Class 1 of IEC/EN 60825-1 with a single fault.
WARNING: Care must be taken especially when controlling this
Laser remotely across a network.
Failure to do so could result in another User being exposed to
hazardous levels of radiation.
It is the responsibility of the Laser Integrator to ensure that when
controlled remotely no hazardous levels of radiation are emitted
when unsafe to do so.
3.3.2
Electrical Hazard
CAUTION: This Laser is designed to BS EN 602041:2006+A1:2009 and must be grounded for safety and to comply
with regional electrical codes.
Failure to do so may result in electric shock and incorrect operation
of the Laser.
This Laser is not provided with any electrical supply cable (cord, flex or lead).
Only qualified technical personnel who are familiar with the equipment should open the
cabinet doors. No electrical hazard exists if the system is operated normally.
3.3.3
Materials Processing Hazards
Materials processing can generate vapour, fumes, solid particulates and other air
contaminants that may irritate, be toxic, or even fatal. It is the responsibility of the user to
ensure that all relevant safety precautions are followed and that any legal requirements are
adhered to in accordance with local legislation. It is advised that Material Safety Data Sheets
(MSDS) for any material to be processed are evaluated and that adequate measures for fume
extraction and venting are considered. Interaction of the beam with certain materials can

Instructions for Use
15
cause potentially harmful levels of visible and invisible radiation to be emitted. Appropriate
protective measures must be taken.
CAUTION: It is essential that any debris associated with laser
processing is removed and cleaned away on a regular basis.
Failure to do so may result in fire.
3.3.4
Other Hazards
While most of the hazard comes from laser radiation, there are certain non-beam hazards that
are often associated with use of laser systems. The Laser requires AC power and is watercooled. Electricity and water, individually or in combination, may create hazards.
Mechanical hazards may include moving parts in cutting, welding and material handling
systems.
High temperatures and fire hazards may also result from the operation of Class 4 lasers.
3.4
Compliance
Within the EU, the Laser is CE marked and is supplied with a Declaration of Conformity. The
standards which SPI Lasers declares that the Laser is in conformity with, and the directives
which SPI Lasers declares that the Laser complies with the requirements of are listed in the
Declaration of Conformity.
Within the USA, the Laser is shipped with an appropriately completed FDA 2877 form.
It is the responsibility of the Laser Integrator to ensure that the integrated laser system
conforms with the appropriate standards and complies with the appropriate directives.
Nonetheless, many of the electronic and labelling requirements have been incorporated into
the Laser to facilitate compliance.

5 redPOWER QUBE Tour
The range of redPOWER QUBE Cabinet Fiber Lasers builds on many years of experience of
SPI Lasers in designing, developing and supplying fiber lasers into a wide range of industrial
laser processing applications. It gives laser integrators the capability to manufacture industrial
laser machines with maximum output power levels from 3kW to 6kW. QUBE Fiber Lasers can
be operated in continuous wave (CW) or modulated (CWM) modes for applications enabled by
fiber lasers and applications traditionally served by lamp pumped and diode pumped solidstate lasers. A flexible control architecture has been implemented using a combination of
analogue, digital and logic user interfaces.
The optical power is generated by two or more PRISM Fiber Laser (FL) Modules which use
SPI Lasers’ proprietary1 GTWave® active fiber technology and reliable pump diodes to
produce a high power, high brightness output. The output from the PRISM Fiber Laser
Modules is coupled together in a PRISM High Power Combiner (HPC) Module and is guided
to the Laser Integrator’s optics by a multimode (MM) delivery fiber supplied with an industry
standard PIPA-Q connector. A ruggedized conduit including SPI Lasers’ Fiber Continuity
Monitoring System (FCMS) protects the delivery fiber.
The PRISM FL Modules together with pump diode PSUs and power distribution and control
systems are enclosed in a cabinet. There are two sizes of cabinet, of different heights,
capable of holding up to two and up to four PRISM FL Modules respectively.

PRISM Fiber Laser Module
Figure 6 redPOWER PRISM FL Module Key Features
A schematic block diagram of the PRISM FL Module is shown in Figure 6. The PRISM FL
Module is represented by the red rectangle and the cooling water circuit is indicated
schematically in blue.
o
Optical Engine
The heart of the PRISM FL Module is the optical engine based on SPI Lasers’
proprietary GTWave® active fiber technology. GTWave takes the optical power of the
pump diodes to generate the high beam quality output of the Laser. It requires no
optical or mechanical adjustments.
o
Pump Diodes
The pump diodes provide the power to the optical engine. Their high reliability means
that they will last for the life of the Laser
o
Pump Drivers
The pump drivers control the drive current to the pump diodes allowing the output
power level of the Laser to be adjusted to different CW levels and to be modulated
over the specified power and frequency ranges.

PRISM High Power Combiner Module
The PRISM High Power Combiner Module takes the outputs from the individual PRISM FL
modules and combines them, with low loss, into one multimode output fiber. Additionally,

the PRISM HPC Module contains sensors to enable the pierce detection and back
reflection monitoring and protection described below.

Beam Delivery and PIPA-Q Optical Connector
The delivery fiber guides the laser power from the PRISM Fiber Laser Module to the
industry standard PIPA-Q optical connector and into the Laser Integrator’s optics. Single
mode and multimode delivery fibers, with different multimode core diameters, are
available. A ruggedized conduit including SPI Lasers’ Fiber Continuity Monitoring System
(FCMS) protects the delivery fiber. The PIPA-Q optical connector and ruggedized conduit
with FCMS are referred to as the beam delivery optic (BDO).

Machine Interface
The Machine Interface allows total operational integration of the Laser into a production
line or cell. Options include Power Control, Parameter Selection and Alarm Reporting. The
function of each of the seven input and seven output signal lines can be configured by the
user. See Section 7.6.5 for more details.

FiberView Control Unit (FVCU)
The FVCU allows the Laser to be controlled either by using the Laser Integrator’s interface
or by using SPI Laser’s FiberView software. The FVCU also takes the inputs from the
sensors in the PRISM FL Module, the pump diode PSU and the safety circuit and
generates alarm and warning signals.

Low Power Mode
Low Power Mode allows the Laser to operate stably at lower powers so that, for example,
marking and cutting can be carried out consecutively on the same work piece. It is
activated through FiberView or by a serial command.

Fiber Continuity Monitoring System (FCMS)
The FCMS is a thin copper wire wound around the delivery fiber. Should the delivery fiber
fail, the escaping laser power fuses the FCMS wire and opens the circuit. Additionally, if
the temperature in the PIPA-Q optical connector is too high or if the PIPA-Q connector is
not mated with the receiver the circuit will be opened.

Back reflection Monitoring and Protection
In some processes the laser power couples poorly into the work piece causing some of the
power to be reflected back into the optical connector and coupled into the delivery fiber.
This back reflection is most likely to occur:
o
when processing highly reflective materials such as brass, copper and
aluminium, especially at normal incidence
o
when operating away from the focal point of the process head
o
during the piercing phase of cutting.
This back reflected power has the potential to cause damage to the optical connector and
delivery fiber due to overheating. It may also to produce power instabilities due to
interaction with the optical engine.
© 2017 SPI Lasers UK Ltd.
Commercial in Confidence
SM-S00521 Revision A 21 February 2017
redPOWER QUBE Cased Fiber Laser
Instructions for Use
29
The Laser is protected against back reflected power with active and passive measures.
Thus there is no need to employ additional optical components (such as optical isolators),
as is common with other fiber lasers, bringing cost and processing disadvantages. The
protection offered by the Laser comes from the design of the optical connector and the use
of sensors to monitor the back-reflected power. In extreme cases, the Laser shuts itself
down before damage occurs.
The optical connector incorporates the SPI Lasers patented2 technology, which channels
back-reflected power away from the delivery fiber via a capillary tube into a water cooled
beam dump, as shown in Figure 7, preventing damage to the delivery fiber or its
mechanical fixings.
Figure 7 PIPA-Q Optical Connector with Protection against Back-Reflection
Thermal monitoring is also used within the optical connector and optical engine to protect
the Laser against back reflected power. If a temperature threshold is exceeded a warning
is generated. When the temperature falls below the threshold the warning will clear. If
higher temperature threshold is exceeded an alarm is generated and the Laser will shut
down. The Laser can be restarted when the temperature falls below the threshold after the
alarm has been cleared.
When processing highly reflective materials such as brass, copper and aluminium, or if in
doubt, contact SPI Lasers for applications advice.

Alignment Laser
An alignment laser provides a visible guide for the alignment of process heads. The
alignment laser is a Class 2 laser, meaning that it is safe to view the beam on a diffuse
work piece, although it is not safe to stare into the beam.

Power Supply Units (PSUs)
The Power Supply Units (PSUs) converts the AC electrical power input to low voltage DC
outputs to supply electrical power to the pump diodes in the PRISM FL Modules and to the
FVCU and other systems within the cabinet.

The inlet and outlet water connections are SMC MS-5HLH-6 type miniature hose elbows
suitable for 6mm LLDPE or polyurethane tubing.
7.3.3
Cooling Water Fittings
SPI Lasers recommends that hoses meeting the requirements of ISO 6224:2011
‘Thermoplastics hoses, textile-reinforced, for general-purpose water applications’ are used for
the main connection to the chilled water supply. A 40mm diameter hose is required.
Figure 9 Hose for Main Connection
The hoses should be pushed fully on to the connectors and secured with hose clips as shown
in Figure 10.
Figure 10 Hoses Connected and Secured
For connection to the optical connector SPI Lasers recommends LLDPE or polyurethane
tubing. John Guest and SMC part numbers are given in Table 4.

Air Conditioning Unit
To ensure that the compressor is adequately lubricated the oil, which has been displaced
during transport, must be allowed to flow back into it. The unit must therefore be allowed to
stand for at least 30 minutes before operation.
The air conditioning unit has a condensation outlet on its base. Ensure that any condensation
is discharged without creating a hazard. Where the humidity is high a 16mm hose can be
attached to the outlet and routed to a drain.

General
CAUTION: This QUBE Fiber Laser is designed to BS EN 602041:2006+A1:2009 and must be grounded for safety and to comply
with regional electrical codes.
Failure to do so may result in electric shock and incorrect operation
of the QUBE Fiber Laser.
For safe operation of this Laser the electrical connections given in the following sections need
to be made. All electrical connections should use cables of the shortest practical length.
For safety, the Laser must be connected to an external protective grounding system before
any other electrical connections are made. The Laser is not ‘hot pluggable’: all electrical
connectors should be mated and secured in place before power is applied.
To operate this Laser the AC power connection and a control connection, which can be digital
(Ethernet, RS-232 or RS-485) must be made.
7.6.2
Connection Locations
All User connections are located inside the right door of the Laser as shown in Figure 11. The
connections are described in more detail in Table 6.

The supply rating is given in Section 15.3.1. The Laser must be grounded and must have a
neutral connection. The cable shall have copper conductors: SPI Lasers does not recommend
using aluminium conductors with the terminals provided in the Laser.
To fit the AC power cable, ensure the isolating switch is in the OFF position and open the
right-hand door. Pass the cable into the cabinet through the cable gland provided at the
bottom of the rear panel. If the cable gland is not of a suitable size or type, for example if
armoured cable is to be used, a blank plate is provided in the cabinet for the Laser Integrator
to mount a suitable cable gland. Route the cable in front of the metal bracket at the bottom of
the cabinet and then up the left side to the main disconnect switch and circuit breaker CB1.
Secure the cable with cable ties to the cradles provided as shown in Figure 12.

SPI recommends the use of bootlace ferrules on finely stranded (class 5 or 6) wires. Connect
the earth/ground wire to the terminal marked PE and coloured green and yellow. Connect the
neutral wire to the terminal marked N and coloured blue. Connect the three phase wires to the
terminals L1, L2 and L3. The phase sequence is not important. Tighten the terminals to the
torques given in Table 8. Copper conductors may creep over time, so it is recommended to
check the tightness of the terminals after a day or two and whenever routine maintenance is
being performed on the laser system. The wire colours shown are standard in Europe: other
territories may use different colours.
Check the continuity of the earth/ground connection before switching on the supply.
If an insulation resistance test is required, remove the transient suppressor plug-ins FV1-FV4
before testing and replace afterwards.

PL1 – Serial Port Control Interface
A cable with standard 9-way D-plug is used to connect the Laser to the system controller or a
PC. The interface operates with signal levels defined by the RS-232 specification. The pin-out
is shown in Table 9.
Pin connections are 2-3, 3-2, 5-5, with no other connections necessary. If connection is made
directly from a PC to the Laser a crossover (NULL MODEM) cable must be used.
RS-232 is the preferred standard. If longer cable runs are required than allowed for by the
RS-232 standard, then an RS-232 to RS-422 converter can be used, but this will be the
responsibility of the user.

PL5 – Machine Interface
The Machine Interface connection is made through PL5, located behind the right door of the
Laser as shown in Figure 11, via a 25 way D-Type Plug (male). It consists of seven inputs and
seven outputs. Each input/output can be software configured to perform a specific function
selected from a list of available functions. The default configuration should be suitable for the
majority of applications, but the configurable flexibility allows Laser Integrators to tailor the
interface to their application if required.
To prevent operational problems caused by ground loops, the Machine Interface I/O hardware
is opto-isolated and requires an external 24V supply, connected as described in Section
7.6.5.1, in order for the outputs to function. The configured output functionality is available in
both Local and Remote operating modes, although the Machine Interface must be provided
with 24V to power the opto-isolation.
Some of the functionality for the input/output is multiplexed depending on the processing
mode, for example; the Laser ON / Process Cycle Start changes functionality depending on
whether the Laser is processing in parameter sets or process cycle mode.
Please read all of this section before using the Machine Interface to be familiar with all its
operation.
7.6.5.1 Machine Interface Supply
The Machine Interface must be powered by a power supply in range of +15 to +30V (typically
+24V) capable of delivering 200mA. Power is provided by connecting the external supply
between PEXT and GNDEXT on the pin allocations shown in Table 10. Two PEXT and
GNDEXT connections are provided for convenience. Each pair is linked internally, and
normally only one of the pair needs to be connected to the external supply. Nominal load for
each input is 5mA. The maximum current capability of each output is 50mA.
7.6.5.2 Default Configuration
Table 10 below shows the default functions for each pin connection on PL5.
Note: the functionality of IN0 – IN6 and also OUT0 – OUT6 can be re-configured using the
FiberView control software.
The External Trigger Input (IN6 in default setting) can be reprogrammed similarly to the other
Inputs. However, if a Trigger input is required it is recommended to use Pin 16 as the
hardware behind this connection is optimised.

SM-S00521 Revision A 21 February 2017
redPOWER QUBE Cased Fiber Laser

The Machine Interface optimised Trigger (IN6) can operate at up to 50kHz. At the maximum
frequency the control system will accommodate up to a 50% duty cycle comfortably. However,
if one of the other inputs (IN0 – IN5) is used, there will be a maximum operating frequency of
4.7kHz for a 50% duty cycle, beyond which input edges may be missed. This maximum
frequency will increase slightly as the duty cycle is reduced.
Note: Do not assign Laser ON function (ID2, Table 10) to Trigger Input Pin 16 due to the high
speed nature of this input potentially causing internal timing conflicts.

7.6.5.4 Basic Operation
With the basic connections above, supplying 24V to the inputs will assert them.
In order for the Laser to be fully controlled through the Machine Interface it is necessary to put
it in Remote Control mode via FiberView. This is done by clicking on the control button
(silhouette of a Man) on the main FiberView toolbar, which turns into a Cog to indicate that
Remote Control is selected. The control status indicator on FiberView will turn red, and the
text alongside it will change to REMOTE.
The necessary connections (based on the default configuration) to start using the Laser in
Remote Control mode are:
Laser Start (IN0, Pin 3)
This takes the Laser from the OFF state to the STANDBY (ready) state.

If this input is clear when entering Remote Control and the Laser is in the ON state, the
Laser will go to the OFF state.


If this input is set when entering Remote Control and the Laser is in the ON state, it will
remain switched to STANDBY.

Clearing this input while in Remote Control will put the Laser in the OFF state.
However, if this function is un-configured from the Machine Interface, the Laser can be started
using serial communications or FiberView in Remote or Local Control mode. The Machine
Interface would then be used for the Laser ON command.
Laser ON (IN1, Pin 4)
This takes the Laser from the STANDBY state to the ON state. A positive edge is required for
this input to act. If the Laser is not in the STANDBY state the input is ignored.

If the Laser is in the ON state, and is put into Remote Control with IN0 set and IN1 set,
the state will remain the ON state.
Trigger Source Select
This needs to be defined for one of the Inputs and set to select external Trigger. If it is clear,
the internal Trigger will be used. When using external Trigger exclusively, this input needs to
be held high continuously. If this function is not defined on the Machine Interface the active
parameter set setting is used.
7.6.5.5 Laser Control Inputs
The Laser can be controlled in Remote Mode by using the inputs on the Machine Interface.
Ensure Remote Control Status is true before using any of the inputs. Connection details are
shown in Table 10.

7.6.5.7 Analogue Input
The waveform applied between Pins 11 and 24 can be used to control the demanded output
power. This is referred to as External Power Control (EPC). The Machine Interface needs to
have an external power supply connected between Pins 1 or 2 and 14 or 15 for this function to
operate. The active pulse shape must also be set into EPC mode using FiberView. (Refer to
Section 9.3.8.)
There are two modes for this function:
Absolute Mode: A signal level between 0V and 10V will linearly control the demand level of the
active pulse shape between 0% and 100% of the overall demand level.
Relative Mode: A signal level between 0V and 10V will linearly control the demand level of the
active pulse shape between 0% and 100% of the set demand level for that pulse shape.

7.6.5.8 Analogue Output
The output on Pin 10 can be used to remotely monitor the output power. This signal is
calibrated linearly from 0V to 10V, to read 10V for the rated output power of the Laser.
The Machine Interface needs to have an external power supply connected for this function to
operate.
This signal is either the CW power when in CW mode or a time averaged value when in
modulated mode. It is the same value as displayed on the power meter panel of FiberView.
7.6.5.9 Diagnostic Outputs
Diagnostic outputs are grouped into the following:

Alarms, which stop operation.

Warnings, which indicate a problem but allow continued operation.
The presence of an alarm or warning is indicated by the transition of the ‘Alarm Status’ or
‘Warning Status’ output from false to true.
Alarm status will remain present until the alarm has been manually reset.
Warning status will remain present until the condition causing the warning has cleared. This
may not require manual intervention.
The actual alarm or warning codes can be read remotely, if required, using the Serial
Interface.
7.6.6
PL81 – Process Cabinet door interlock switches and PL82 –
Power Supply Remote Control
The Laser provides an ‘E-shutter’ safety function which puts the Laser into a safe state if the
process cabinet door is open at the same time as a voltage is present at the pump diode PSU
outputs. The E-Shutter is a dual channel circuit, using two different types of CLPD,
programmed independently using different software tools, that conforms to EN ISO 138491:2015, (Safety of machinery. Safety-related parts of control systems. General principles for
design) category 4, performance level d (PL d).
The E-shutter monitors two process cabinet door interlock switches on PL81 and the actual
pump diode PSU outputs during normal operation and it also checks the process cabinet door
interlock switches and the pump diode PSU output monitoring circuits for faults.
The E-Shutter will shut the laser down via the emergency stop safety function if the door is
opened while the PSUs are enabled.
If one process cabinet door interlock switch opens and recloses without the other interlock
switch opening, this is detected as a fault. If the pump diode PSU outputs do not agree with
the enable command within a 1 second time window, this is also detected as a fault.
The operating time of the E-Shutter is determined by the time taken to discharge the
capacitors at the output of the pump diode PSU through the dump resistors, and is typically

Instructions for Use
56
500ms. The E-Shutter circuits confirm that the pump diode PSU outputs have been
discharged to a voltage which is too low to operate the laser diodes. The E-Shutter has a
minimum cycle time specification of 5 seconds. Each time it operates the energy in the
capacitors must be dissipated by the dump resistors. Repeated cycling at less than the
minimum cycle time could overheat the resistors.
The connections to PL81 are shown in Figure 17.
Figure 17 Connections to PL81
Two door interlock switches must be used. These are supplied from the internal 24V DC
supply and should be “volt-free” contacts. One interlock switch is connected to the positive
side of the supply and the other to the negative. This allows wiring faults to be detected;
however it means that two interlock switches are always required. A single interlock switch
cannot be used to control both inputs. Dual interlock switches are available specifically for
process cabinet safety interlocks from several manufacturers, including Allen Bradley, Pilz,
Rockwell (GuardMaster) and Schneider (Telemecanique). The 24V supply is SELV and must
be appropriately separated from non-SELV circuits. Both interlock switches should open when

the door is opened. The safety function monitors both interlock switches and if one interlock
switch opens and closes again without the other interlock switch opening, the safety circuit
detects this as a door interlock switch fault.
If process cabinet door interlock switches are not used, PL81 pin 1 must be linked to pin 2 and
pin 3 must be linked to pin 4.
WARNING: Defeating interlocks could result in exposure to
hazardous levels of radiation.
It is the responsibility of the Laser Integrator to ensure that no
hazardous levels of radiation are emitted when unsafe to do so.
PL82 comprises a PSU enable input and PSUs safe and PSUs ready status outputs. The
input and outputs are isolated from the laser control circuits, but there is also access to the
internal laser 24V DC supply. The input and outputs are nominally 24V DC and should be
considered as SELV. The isolation is provided only to prevent ground loops. The input current
is nominally 10mA. The status outputs are not polarity sensitive and are rated up to 30V DC
and 100mA.
The PSUs are enabled when the PSU enable input is on.
The PSUs safe output indicates that all the pump diode power supplies are disabled and their
output voltage has discharged to a level that is too low to cause output from the pump diodes.
The PSUs ready output indicates that all the pump diode power supplies are enabled and are
at full voltage ready to operate the pump diodes.
The safe and ready outputs are normally complementary, with a small delay between them.
The E-Shutter incorporates timers that monitor the safe and ready signals. If the PSUs take an
excessive time to enable or disable, this is detected as a fault.

PL91 – External Interlock and Remote Reset
The Laser has a high integrity emergency stop safety function. It is a dual channel circuit,
requiring two volt-free contacts, that conforms to EN ISO 13849-1:2015, category 4,
performance level e (PL e). It provides the Remote Interlock required for compliance to
EN 60825-1:2007.
PL91 provides access to this circuit and provides a 24V DC supply. The 24V supply is SELV
and must be appropriately separated from non-SELV circuits. External controls or interlocks
must be “volt free“ and dual channel. The safety function monitors both channels. If one
channel opens and closes again without the other opening, the safety circuit will detect this as
a fault and raise an alarm. The alarm can be reset by opening and closing the other channel.
The Laser also has a manual reset safety function to prevent unexpected start up. The reset
must be operated after applying the electrical supply and after operation of the emergency
stop, key switch or external interlock. A reset is also required if the E-Shutter detects a fault. A

Typical connections to PL91 are shown in Figure 21.
Figure 21 Typical Connections to PL91
If the external interlock is not used, PL91 pin 3 must be linked to pin 4 and pin 5 must be

PL91 is a 6 way 5.08mm pitch connector. A suitable mating socket is Phoenix Contact part
number 1778027. It accepts wire sizes from 0.25mm2 to 2.5mm2 or 24AWG to 12AWG, the
strip length is 7mm or 0.25" and the tightening torque is 0.5-0.6Nm.
7.6.8
PL96 – Cooler Interlock
PL96 provides a general purpose, single channel interlock, which may be used to prevent the
laser operating if the external cooling water supply is off or above the maximum temperature.
PL96 also provides a 24V DC supply which is SELV and must be appropriately separated
from non-SELV circuits. External controls or interlocks must be “volt free“. The current is
nominally 5mA.The interlock is not a high integrity safety function and must not be used to
protect Users from laser radiation.

PL98 – Remote Indicators
The Laser provides outputs for indicators, or for use as inputs to a user supplied control
system, on PL98. The outputs are nominally 24V DC with a maximum rated current of 100mA.
The 24V DC supply is provided by the laser and is SELV. The connections to PL98 must be
appropriately separated from non-SELV circuits.
There are 5 outputs:
Reset
This output is on when the emergency stop safety function has been reset. It duplicates the
blue lit reset button on the front panel.
Emission

7.6.10 SK2 – Ethernet
The Ethernet port can be used to connect the Laser to a LAN or the network port on a single
PC. The port uses standard RJ45 connectors. A standard straight through cable is required for
connection to a LAN. For direct connection to a PC a cross-over cable needs to be used if the
PC network card doesn’t support auto cross over detection.
FiberView version 3.5.2 or higher needs to be used for control of the Laser over an Ethernet
connection.
7.6.11 Minimum Interface Connections
Initially, the minimum connections to allow the laser to operate will be to the Process cabinet
door interlock switches connector (PL81), the External Interlock and Remote Reset connector
(PL91), the cooler interlock, (PL96) and a Serial (PL1) or Ethernet (SK2) port. The serial
interface should be connected to a PC which has FiberView software installed.
The minimum hardware connections needed to operate the laser are shown in Table 13.

Routing the Beam Delivery Optic
CAUTION: If damage to the conduit or optical connector is
suspected, stop using the QUBE Fiber Laser and contact SPI
Lasers immediately.
Failure to do so may result in exposure to harmful levels of
radiation.
Delivery fibers and optical connectors are precision parts.

Avoid contamination and mechanical stress when handling.

Avoid shocks and impacts on optical connectors

Avoid pulling, twisting and over-bending of the conduit

Beam delivery optics are less robust than electrical cables, although superficially they look
similar. If fibers are treated and handled as electrical cables, they will fail prematurely. Fiber
replacement can be both time-consuming and expensive.
Avoid kinking and twisting the conduit by unrolling the coil, rather than pulling it straight.
If the BDO is led through openings, the openings must be sufficiently large that the optical
connector with protector can be led through without applying any force.
In static applications (where BDO and process head do not move):

The BDO may be routed alongside power, water or control cables provided these do
not impose stresses or strains on the conduit.

The conduit must not be bent tighter than the minimum bend radius at any point along
the route. (Refer to Table 31.)

The maximum tensile loading must not be exceeded. (Refer to Table 31.)

The conduit must be supported at points along its length, at intervals no greater than
3m, to prevent gross movements under its own weight during the production
sequence.

At the support points, the conduit must be held using mechanical parts which prevent
bends tighter than the minimum bend radius and which do not apply a compressive
force on the conduit.

The external surface of the conduit must be prevented from rubbing or abrading at
support points or on any other parts in the workstation (e.g. jigs, fixtures, production
parts, workstation walls, floors, robot parts).
In dynamic applications (where BDO and process head move), additionally:

The BDO must be routed separately from power, water and control cables.

The BDO must be held off the floor and routed along a path so that the conduit is not
bent tighter than the minimum bend radius at any point along its length all through the
production sequence.

The conduit must never be pulled tight at any point along its length during the
production sequence.

If a balancer is used, tie the conduit to the rope of the balancer so that:
o
The rope takes the tensile loading and not the optical connector.
o
The conduit has sufficient slack for all kinds of robot motions without bending
below the minimum bend radius.

Acceleration and deceleration of the BDO and process head must be kept to a
minimum consistent with achieving process cycle time.

At BDO installation and periodically during operation (e.g. once per shift), a dry run of
the production sequence should be made. The BDO motion should be checked to
ensure that the routing still complies with the points of good practice above.

Connecting and Disconnecting the PIPA-Q
Optical Connector
Precautions
CAUTION: The protective cap placed on the optical connector is intended
to protect the connector from contamination during shipping and when the
QUBE Fiber Laser is not in use for extended periods, and to prevent the
FCMS circuit from being accidentally closed. It MUST NOT be treated as
a beam stop.
Operating the QUBE Fiber Laser with the protective cap in place may
result in damage to the QUBE Fiber Laser. In addition, due to the
elevated temperatures associated with operating the QUBE Fiber Laser at
high power with the protective cap in place, contact may lead to personal
injury.
CAUTION: The protective tape attached to the optical connector is
intended to protect the connector from contamination during shipping.
Operating the QUBE Fiber Laser with the protective tape in place may
result in damage to the QUBE Fiber Laser.
Each optical connector change incurs the risk of contaminating or damaging the connector.
Therefore optical connectors should only be changed when required and the local
environment should be as clean and dust free as possible to avoid introducing debris into the
process head.
The protective cap and protective tape must only be removed after the BDO is routed and
immediately before the optical connector is inserted into the process head. Remove the
protective cap slowly holding the optical connector downwards to avoid contamination settling
on the window.
Do not grease optical connectors
Keep the optical connector facing downwards when uncovered and not installed.
Do not touch the window
The optical connector must not be subjected to forces caused by dropping, impacting or
collision with heavy objects.
Optical connectors must be inspected, and cleaned if necessary, before being reinserted. See
Section 12.3.
The PIPA-Q optical connector should be installed as follows:

Disconnecting the PIPA-Q Optical Connector from the Process
Head
Each optical connector change incurs the risk of contaminating or damaging the optical
connector. Therefore optical connectors should only be changed when required and the local
environment should be as clean and dust free as possible to avoid introducing debris into the
receiver.
Using clean, dry compressed air or nitrogen, blow away any dust from the area where the
optical connector enters the receiver.
Using a clean cloth or tissue, wipe down the area where the optical connector enters the
receiver to remove the last traces of dust or debris.
Remove the PIPA-Q optical connector from the receiver using the 2-step process
Unlocking Step 1:
Pull the locking sleeve out by 2mm
Unlocking Step 2:
Turn the locking sleeve through 37° in an anticlockwise direction and remove the optical

Alarm conditions include:

Optical Fault

Back reflection detected

Output Fiber over-temperature

Supply ‘brown-out’

Internal over-temperature
In the case of an optical fault, the Laser may enter Safe Mode. In this mode, the Laser is
limited to a pre-configured parameter set that will output a low energy, low frequency pulse.
This allows checks to be made without making any damage worse.
Optical fault detection needs to be sensitive enough react quickly to minimise damage.
However, there may be a potential for false detection of optical faults. In this case, the safe
mode recovery routine will take the Laser out of safe mode.
8.3.2
Warnings
A warning is generated by conditions which are of concern, but do not put the Laser into the
OFF state. Warnings are removed automatically when the condition is removed.
Warning conditions include:


9 Laser Control and FiberView
9.1
Overview
FiberView is the Graphical User Interface (GUI) program specifically written for redPOWER
Fiber Lasers with the FiberView Control Unit. FiberView is used to monitor and control the
redPOWER Fiber Laser, program parameters and process cycles, alert the User to any
maintenance requirements and to aid in fault diagnosis. FiberView is an advanced laser
control system offering many features not available in other products. However the protocol for
controlling redPOWER Fiber Lasers is available from SPI Lasers to allow users to integrate
control of redPOWER Fiber Lasers into an overall system controller.
The initial configuration of the redPOWER Fiber Laser can be set from FiberView, and then
the operating parameters selected and internal parameters monitored during operation.
Different levels of access (Maintenance, Supervisor, and Operator) are allowed to the features
of the program for control of the redPOWER Fiber Laser in a production environment.
If the FiberView program is run with no laser connected to the PC, then an option is available
to run in a simulation mode. This mode is useful for safely familiarising the user with the
operation of the program.
9.2
Basic Operation
Launch the FiberView Program. For the normal installation there will be shortcuts on the
Desktop and in the Start menu to do this.
On starting the FiberView program in its default mode, a dialog box similar to Figure 28
appears. The FiberView application will automatically search for redPOWER Fiber Lasers
connected via RS-232 and Ethernet (local or network) connections. FiberView displays a list of
all the redPOWER Fiber Lasers it can find. Select the desired connection, and then click on
“Connect to Laser …” to enable FiberView to control that redPOWER Fiber Laser.

Sections 7.6.3 or 7.6.5).
2. Use the Configuration button to check the baud rates that are used for the search. By
default all baud rates are selected but to speed up the search a single baud rate may
be selected. Make sure the correct baud rate is ticked.
3. If a redPOWER Fiber Laser is connected by Ethernet, make sure the PC has the
correct IPv4 configuration. To check this go to Start->Control Panel->"View Network
Status and Tasks" or "Network and Sharing Center". Click “Local Area Connection”
and then "Properties" . Select "Internet Protocol Version 4 (TCP/IPv4)" from the list
and click the "Properties" button.
o If the Ethernet connection is on a LAN then select either the "Obtain an IP
address automatically" or "Use the following IP address" options.
o If the Ethernet connection is directly via an Ethernet cable then select the "Use
the following IP address" option.
For a fixed address, if the router’s LAN or the redPOWER Fiber Laser’s IP address is,
for example, 192.168.1.1, enter the IP address 192.168.1.x (where x is a value
between 2 and 255).
Note: The IP addresses used above are for example purposes only.
4. If the search list is empty then connect to a redPOWER Fiber Laser using RS-232.
Run the search and select an RS 232 connected redPOWER Fiber Laser. Check the
Ethernet settings by clicking the Communications Settings button.

The hardware on the redPOWER Fiber Laser stores set-up information: e.g. programmed
parameter sets, alarm and warning levels, calibration data and configuration. On start-up,
FiberView reads this information from the redPOWER Fiber Laser. Thus one installation of
FiberView can be connected to any redPOWER Fiber Laser, and will know its status and
limitations. The information read back from the redPOWER Fiber Laser is displayed in the
Laser Tabs area.
It is possible to have more than one instance of FiberView running on a single PC, with each
instance controlling a separate redPOWER Fiber Laser.
On connecting to a redPOWER Fiber Laser, FiberView displays its overview screen, similar
to Figure 29.

Maximum demand setting is 102%. This extra headroom can be used to fine tune the process,
or compensate for small variations over time in the processing conditions.
In Single Sector Pulsed Mode a frequency and pulse width are set. In this mode the pump
drivers are switched on and off rapidly. The effect is to ‘chop’ the CW output into a series of
pulses.
Returning to the Laser Overview Screen (Monitors Tab, or on the Menu bar select: View –
Windows – Laser Overview), will allow the redPOWER Fiber Laser’s conditions to be
monitored while it is running.
To operate the redPOWER Fiber Laser use the buttons in the Tool bar. Click on the green

Ramp Up
When output is demanded the power will linearly increase from zero to the demanded level
over this period.
9.3.6
Ramp Down
When the output is turned off, the power will decrease to zero over this period.
9.3.7
Trigger Mode
Selecting one of the External Modes allows the Laser to be controlled by a Trigger signal
applied to the Trigger Input (Pin 16) on the Machine Interface (PL5, Section 7.6.5).

Internal: Output pulses generated at rate set in the parameter editor, using internal
function generator.

External Edge Triggered: One output pulse is generated for each positive going edge
on the Trigger inputs. Not for CW mode.

External Gated: Output is enabled while the Trigger input is held high, and turned off
for Trigger input low.
9.3.8
EPC (External Power Control)
Allows the demand level to be controlled by the value of the voltage applied to the Analogue
Input (Pins 11 and 24) on the Machine Interface (PL5, Section 7.6.5).
The EPC indicator in the Status Indicators area will turn red if EPC is in use for the Active
pulse shape.

Off: Analogue Input level ignored.

Absolute: An input of 0-10V will control the peak demand for the pulse shape from 0100%.

Relative: An input of 0-10V will control the peak demand for the pulse shape from 0%
to the maximum value set in the pulse shape parameters.
Note: By setting the pulse shape to CW and using EPC mode, the output of the Laser can be
made to follow any arbitrary externally applied waveform.
9.3.9
User Defined Pulse Shapes
Any arbitrary pulse shape can be defined using the Shape Editor. The Shape Editor works
with dimensionless shapes that are then saved as a particular User Defined pulse shape. This
pulse shape can be used in any parameter set, where it is scaled to the peak power and pulse
width associated with that pulse shape.

When the shape is completed, click on the “Save to Laser Storage” icon and assign it to a
User Defined shape number (which can later be used in any parameter set). A copy of the
shape can be saved to disc using the “Save to Local Storage” option.
The ‘Library’ and ‘Usage’ buttons can be used to see which pulse shapes are currently in use
by the Laser.
9.4
Process Cycles
Process Cycles are an automation feature of redPOWER Fiber Lasers. They allow a
programmed sequence of Parameter Sets to be output using minimal input to control an entire
sequence, for example when a single part has to be processed with different types of spot and
seam welds at different positions around the part. Process Cycles are constructed from one or
more elements known as Steps. Each Step holds a Parameter Set reference and control
attributes. A Process Cycle can be programmed to execute fully automatically from start to
finish, or to require an external input / serial command to change between programmed Steps,
or any combination of automatic and manual control.
The FVCU has the capacity to store up to 1000 steps which can be grouped into up to 50
Process Cycles. In this way, for example, a single Process Cycle of 1000 Steps or 50 Process
Cycles of 20 Steps can be set up. Any number of Steps can be linked to create a range of
Process Cycles, provided that there are no more than 50 Process Cycles and no more than a
combined total of 1000 Steps.

Figure 32 shows Steps grouped into Process Cycles. The Process Cycles contain from one to
16 Steps.
Figure 32 Steps Grouped Into Process Cycles
A 16 character name is stored with each active Process Cycle to allow it to be identified. For
example, the name of the Process Cycle could be the name of the part the Process Cycle has
been developed to process.
Process Cycle Steps determine the sequence of Parameter Sets that are executed, along
with their timing and transition type. All of the other information required to specify the output
is determined by the Parameter Set.
To edit a Process Cycle select by Process Cycle Tab, or View – Windows – Process Cycle
Editor on Menu Bar.
The Process Cycle Steps contain the attributes listed in Table 15. The attributes can be
assigned to each Step using the Process Cycle editor, as shown in Figure 33.

Alignment Laser
The alignment laser of the redPOWER Fiber Laser assists in aligning the process tool in the
correct position on the work piece. Red light from a low power laser diode is transmitted to the
work piece using the same delivery fiber as the main laser output.
The alignment laser can be activated at any time by clicking on the diode icon on the Tool Bar.
The state of the redPOWER Fiber Laser is taken into account when activating the alignment
laser, as follows:
Laser OFF state:
The alignment laser will turn on.
Laser STANDBY state:
The alignment laser will turn on.
Laser ON state:
The Laser will be emitting, so when the alignment laser is activated its state will be
reported as ON, but its output will be OFF. When the laser enters STANDBY or OFF, the
alignment laser output is automatically switched ON.
Note: If the alignment laser is left ON, it will automatically switch off after 30 minutes.

11 Machine Interface Reference
11.1
Overview
The Machine Interface for the redPOWER QUBE Fiber Laser consists of seven inputs and
seven outputs. They are available to Laser Integrators on connector PL5 as shown in Table
10. Each input and output can be configured to perform a specific function selected from a list
of available functions. This configuration can be changed to suite the laser’s operation. The
default configuration should be suitable for the majority of applications, but the configurable
flexibility allows laser integrators to tailor the interface to their application if required.
This section describes setting up the Machine Interface Laser using the default configuration.
SM-S00499, Fiber Laser Serial Communications Protocol is available to explain how to
reconfigure the Machine Interface functionality if the default configuration does not suit the
required application.

Detailed Function Description
o
SETting the input sequences the state to the STANDBY state.
o
CLEARing the input switches the state to the OFF state.
o
When switching into Remote Control, the state of the Laser Start input is acted
upon depending on the state of the Laser as follows:

When the state is OFF, and Laser Start input is SET, the state will
remain OFF when entering Remote Control. The Laser Start input must
detect a positive edge to change the state. Alternatively a software
command can be issued to sequence the state to the STANDBY state
while the input remains SET.

When the state is the STANDBY or the ON state, and Laser Start input
is CLEAR, the state will switch to the OFF state when entering Remote
Control. In this case, the Laser Start input is level sensitive. While in
Remote Control, the only way to sequence the state into the STANDBY
state is to SET Laser Start.

When the state is the STANDBY or the ON state, and the Laser Start
input is SET, the state will not switch to the OFF state when entering
Remote Control. In this case, the state of the Laser Start input is level
sensitive and the state is also dependant on the Laser ON / Process

Detailed Function Description
a) Parameter Set Operation


When the Laser is in Remote Control this input function provides the following action:
o
From the STANDBY state, setting the input changes the state to the ON state
or the RAMPING UP state if a ramp up time is configured in the active
parameter set.
o
From the ON state, clearing the input changes the state to the STANDBY state
or starts the RAMPING DOWN state if a ramp down time is configured in the
active parameter set.
When in the STANDBY state and switching into Remote Control the Laser ON input is
acted upon depending on the initial state.
o
When the state is the STANDBY state, and the Laser ON input is SET, the
state will not switch to the ON state when entering Remote Control. In this case
the Laser ON input is edge Triggered.
o
When the state is the ON state, and the Laser ON input is CLEAR, the state
will change to the RAMPING DOWN (if any ramp is set) or STANDBY state
when selecting Remote Control. In this case the Laser ON input is level
sensitive.
o
When the state is the ON state, and the Laser ON input is SET (and the Laser
Start input is either not configured or configured and SET), the state will remain
the ON state. In this case the Laser ON input is level sensitive.
o
When the state is the OFF state, or transitioning to the STANDBY state, and
the Laser ON input is SET, the state will not transition to the ON state when it
enters STANDBY.

b) Process Cycle Operation


When the Laser is in Remote Control this input function provides the following action:
o
From the STANDBY state, setting the input starts a Process Cycle.
o
From the Process Cycle Active state, clearing the input stops a Process Cycle.
If a ramp down time is set in the Parameter Set linked to the active Process
Cycle Step, the ramp down will commence when the Process Cycle Start input
is CLEARED and the state will transition to the STANDBY state.
When in STANDBY and switching into Remote Control the state of the Process Cycle
Start input is acted upon depending on the initial state.
o
If the state is the STANDBY state, and the Process Cycle Start input is SET, a
Process Cycle will not start when entering Remote Control. In this case the
Process Cycle Start input is edge Triggered.
o
If a Process Cycle is active when entering Remote Control it will stop
regardless of the Process Cycle Start input condition. If a ramp down time is set
in the Parameter Set linked to the active Process Cycle Step, when entering
Remote Control the ramp down will commence and the state will transition to
the STANDBY state.
o
When the state is the OFF state, or transitioning to the STANDBY state, and
the Process Cycle Start input is SET, a Process Cycle will not start when it
enters STANDBY.

Care must be taken to ensure the Laser Start and Laser ON / Process Cycle Start
inputs (if configured) are in the correct state when entering Remote Control.

This function is only operational in Remote Control and when the state is the
STANDBY state. If this function is configured and SET, when the STANDBY state is
entered from the OFF state, the state will not transition to the ON state. The configured
input must be cycled to provide a leading edge to transition the state to the ON state.

Detailed Function Description
o
This input function is used in conjunction with the Process Cycles feature of the
Laser. It is used to advance a Process Cycle on to the next step when the
active Process Cycle Step is configured to manual step mode, or the step
duration is infinite. The input function becomes active when the step duration
(either time or shots) has completed and the step is waiting to advance. The
Step input is active from the start of the step execution for steps configured with
an infinite duration (duration = 0).
o
An output function can be configured on the Machine Interface to indicate that
the Process Cycle is waiting for a Step input in order to advance.
o
If the function is not configured on the Machine Interface a Process Cycle
cannot be advanced using the Machine Interface. In this situation, steps can be
advanced using the serial protocol, or steps must be configured to
automatically advance.

12 Maintenance
WARNING: Never attempt to modify internal or external
components not covered in this section.
Doing so may lead to serious personal injury, performance
degradation and premature failure
The Laser is designed to be maintenance free. There are no parts or mechanical items within
the Laser that require replacement during the specified operating life of the Laser. However
periodic inspection of the Laser is recommended.
12.1
Periodic Inspection
The items listed below should be inspected periodically for damage which may affect the safe
operation of the Laser. The frequency of the inspection will depend on the environment in
which the Laser is installed.

The enclosure

The conduit

The optical connector

The electrical connections

The water connections and hoses
It is important that cooling water connections and hoses are regularly inspected and
maintained in order to reduce the possibility of leakage or external component failure.
Refer to Sections 7.3 for instructions regarding water cooling connection and disconnection
from the Laser.
12.2
General Cleaning
CAUTION: Do not operate the QUBE Fiber Laser if any of the
hazard warning labels are missing or damaged such that they
cannot be read properly.

Cleaning Optics
The cleanliness of all optical surfaces is critically important. Contamination in the optical path
from environmental dirt or dust, or finger grease from incorrect handling must be avoided as
the contamination will be burned into the optical surface causing permanent damage. Before
being exposed to high power, connector end faces should be inspected, preferably with a
magnifying aid, and carefully cleaned if any contamination is observed.
If the window on the optical connector is damaged, or too dirty to clean, replacements are
available to order from SPI Lasers. The PRISM Fiber Laser must never be operated without
the window in place.

Packing and Moving
When coiling the BDO appropriately twist the conduit to ensure that the coils lie flat. The
conduit is very flexible and easily bent when coiling. Ensure that is never bent to less than the
minimum bend radius. Never pull on the optical connector to untangle the conduit. Particular
care should be taken with regard to possible damage to the optical connector when coiling the
bean delivery optic. Do not drop the optical connector or allow it to hit surfaces or other
objects.
The Laser can be moved a short distance on its castors.
If it is to be moved further use a forklift or pallet truck.
If it to be transported to another site or returned to SPI Lasers Pack the Laser in the original
packaging and include all original accessories and documentation as detailed in the original
inventory. The correct and original packaging should be used to prevent damage in transit. If
all or part of the original packaging is unavailable, contact SPI Lasers for replacement items.
This Laser is heavy. To avoid the risk of personal injury or damage to the Laser lift only using
a forklift or a hoist attached to the lifting eyes on the cabinet, and move using a forklift or pallet
truck Take care of the centre of gravity and ensure that the Laser remains vertical.

Refer to Section 7.2 for further requirements for location and environment.
Note that auxiliary equipment is required to operate the Laser. The environmental operating
conditions of the auxiliary equipment must be observed.
Water must not be allowed to condense on or in the Laser. When the Laser is to be used in a
humid environment, it can be provided, as a factory fitted option, with an air conditioning unit
to dry the internal air and so prevent condensation. Condensation can be avoided by using
cooling water at a temperature appropriate to the local humidity. Figure 65 can be used to
determine if the atmosphere is condensing. The solid lines cover the permitted cooling water
temperatures for the Laser. For example, if the ambient air temperature is 25°C and the
relative humidity is 40% then there will be no condensation for any cooling water temperature
in the specified range as the condition is below the 18°C cooling water curve. However, if the
ambient air temperature is 30°C and the relative humidity is 80% then the cooling water
temperature should be above 26°C to prevent condensation.

Notes

Drinkable tap water is likely to meet these requirements, and water meeting the requirements
of VDI3803, Appendix B, Table B3 does.
When designing the water cooling system, the Laser Integrator should consider that:

deionised water is not permitted in the cooling circuit as the generally high levels of
dissolved O2 and CO2 in deionised water cause corrosion.

aluminium and plain carbon or low alloy steels should not be used, as the cooling
circuit of the base plate is copper and the internal surfaces of the PIPA-Q optical
connector are nickel-plated and stainless steel. Stainless steel and insulating materials
(polymers) may be used. Galvanic corrosion may occur if materials with widely
different electrochemical potentials are used.

the temperatures specified for the cooling water may sustain bacterial growth. Bacterial
growth may reduce both the flow rate and the efficiency of heat transfer as well as
being a health hazard.

hard water (water that has high mineral content) may cause scaling in the cooling
circuit reducing both the flow rate and the efficiency of heat transfer.

pre-treated water and additives for prevention of corrosion, scaling and microbial
growth are available commercially, for example from NALCO and Optishield. Additives
may reduce the heat capacity of the water. The flow rate must be increased to
compensate.

The PIPA-Q connector is provided with two contacts (indicated in Figure 4) which must be
short-circuited to complete the continuity circuit. Generally the receiver on the process head,
beam switch etc into which the connector is inserted will perform this function so ensuring that
the continuity circuit cannot be closed until the connector is correctly installed. The contacts
must not be connected to ground.
