Laser Hazard Information
WARNING: The output aperture of this TruFiber Laser may emit
both invisible and visible laser radiation.
The invisible laser radiation will be Class 4 laser radiation. The
invisible radiation can be up to approximately 115% of rated power
CW in normal operation and 150% with a single fault. The
wavelength of this invisible radiation is in the range 1050-1250nm.
Additionally, this Laser contains embedded lasers that emit invisible
laser radiation up to approximately 170% of rated power CW in
normal operation and 250% CW with a single fault. The wavelength
of this invisible radiation is in the range 900-1000nm.

Hazards
3.3.1
Laser Hazards
All Warnings, including those in the Safety Notes and those in other sections of this operator’s
manual, 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 should be taken especially when controlling this
TruFiber 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 TruFiber 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 TruFiber 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 remove the
covers from the Laser. No electrical hazard exists if the system is operated normally.

3.3.3
Noise Hazard (Air Cooled Lasers)
WARNING: Air cooled TruFiber Lasers may emit hazardous levels
of noise. There may be sound pressure levels of 80dB 1m in front
of the fans and of 75dB 1m in other directions when the fans are
running at full speed.
Failure to apply appropriate noise reduction measures may result in
• permanent hearing loss
• tinnitus
• tiredness, stress, headaches
• other effects such as loss of balance, loss of awareness
• interference with speech communication
• inability to hear acoustic warning signals
Laser Integrators should review the impact of the noise levels given above and apply
appropriate noise reduction measures to reduce the noise level at relevant locations to below
that required by regional requirements or legislation.
3.3.4
Thermal Hazard
In normal operation the Laser should not get hot. However, if a fault occurs the external surfaces
may get hot.
3.3.5
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 cause potentially
harmful levels of visible 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.
3.3.6
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 may be watercooled. Electricity and water, individually or in combination, may create hazards.
It is recommended that water cooled Lasers should be installed sufficiently far above the floor
to reduce the risk from electricity in the case of flooding: at least 250mm is recommended.

5 TruFiber P Compact Tour
The range of TruFiber P Compact Lasers builds on many years of experience of TRUMPF Laser
UK Ltd 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 300W to 2kW and with air and water cooling.
TruFiber 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 solid-state lasers. Flexible control architecture has been implemented using a
combination of analogue, serial and logic user interfaces.
The optical power is generated by a Fiber Laser Module using TRUMPF Laser UK’s proprietary1
GTWave® active fiber technology and reliable pump diodes to produce a high power, high
brightness output. The output from the Fiber Laser Module is guided to the Laser Integrator’s
optics by a single mode (SM) or multimode (MM) delivery fiber supplied with an industry
standard PIPA-Q optical connector. A ruggedised conduit including TRUMPF Laser UK’s Fiber
Continuity Monitoring System (FCMS) protects the delivery fiber.

In air cooled Prism Modules, the cooling is provided by air blown across cooling fins by fans.
5.2.1
Optical Engine
The heart of the Laser Module is the optical engine based on TRUMPF Laser UK’s
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.
5.2.2
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.
5.2.3
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.
5.2.4
Beam Delivery and PIPA-Q Optical Connector
The delivery fiber guides the laser power from the 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, and the

TruFiber P compact (FD44-A/W)
PIPA-Q has water cooled and air cooled versions. A ruggedised conduit including TRUMPF
Laser UK’s Fiber Continuity Monitoring System (FCMS) protects the delivery fiber. The
PIPA-Q optical connector and ruggedised conduit with FCMS are referred to as the beam
delivery optic (BDO).
5.2.5
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 open.
5.2.6
Machine Control Interface (MCIF)
The MCIF 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 digital lines can be configured by the user. See
Section 7.6.7 for more details.
5.2.7
FiberView Control Unit (FVCU)
The FVCU allows individual Lasers to be controlled either by using the Laser Integrator’s
interface or by using TRUMPF Laser UK’s FiberView software. The FVCU also takes the
inputs from the sensors in the Prism Module, the pump diode PSU and the safety circuit and
generates alarm and warning signals.
5.2.8
Low Power Mode
Low Power Mode, available on 500W Lasers and above, 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.
5.2.9
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 setting focus at high power.
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.

TruFiber 300 to 2000 P Compact (FD44) Operators Manual

TruFiber P compact (FD44-A/W)
The Laser is protected against back reflected power with active and passive measures.
Thus, there is no need to employ additional optical components, 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 TRUMPF Laser UK’s 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 10, preventing damage to the delivery fiber or its
mechanical fixings.
Figure 10 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 TRUMPF Laser UK for applications advice.
5.2.10 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.
5.2.11 Power Supply Unit (PSU)
The Power Supply Unit (PSU) converts the AC electrical supply input to a low voltage DC
output to supply electrical power to the pump diodes in the Prism Module and to the FVCU.

radiation is not accessible when the key is removed.
5.2.13 Emergency Stop
A latching emergency stop button is located on the Laser’s front panel. Operation of the
emergency stop button puts the Laser to OFF (in alarm state).

FiberView Graphical User Interface
TRUMPF Laser UK’s Graphical User Interface, FiberView, allows Users to control this Laser
over a RS232 or Ethernet interface.
FiberView is used to monitor and control Lasers, to program Shapes, Parameter Sets and
Process Cycles, to alert the User to any maintenance requirements, and to aid in fault diagnosis.
FiberView is an advanced and versatile laser control system offering many features not
available in other systems, but it still can be used to perform simple functions such as turning
laser emission on and off, turning the alignment laser on and off, and monitoring Laser
parameters, and alarms and warnings.
The versatility of FiberView comes from its ability to build full Process Cycles out of Parameter
Sets which, in turn, are constructed from basic Shapes. Built-in Shapes are CW, single sector
pulse and sine. Additionally, FiberView allows up to 50 User defined, multi-sector Shapes. The
CW, single sector pulse and sine Shapes are used to generate simple CW, pulsed or sinusoidal
outputs from the Laser.
Figure 11 Parameter Set Editor on FiberView
Users can define multi-sector Shapes using Shape Editor - a simple graphical interface within
FiberView. Each Shape can contain up to 1000 sectors, which can be added as points, pulses,
ramps or levels. Once added the sectors can be adjusted by drag and drop.
Any arbitrary pulse shape can be defined using the Shape Editor then saved either to the Laser
or to local storage. There is no power or time duration associated with the Shape: this is added
when the Shape is used in a Parameter Set. A Shape can be used in any Parameter Set, where
it is scaled to the peak power and pulse width associated with that Parameter Set.

Process Cycles are an automation feature of TruFiber P Compact Lasers. They allow a
programmed sequence of Parameter Sets to be output using minimal input to control the entire
sequence. For example, a single Process Cycle could be used when a part has to be made with
different types of spot and seam welds at different locations. Process Cycles are constructed
from one or more elements known as Steps. Each Step holds a Parameter Set reference and
Control Attributes. The Control Attributes of the Steps can be set so that the Process Cycle
executes fully automatically from start to finish, or to require an external input or command to
execute the next Step, or any combination of the two.
Figure 13 Process Cycle Status (left panel) and Editor (right panel) on FiberView
The breakdown of a Process Cycle into Steps, each with its Parameter Set and Control
Attributes, and Shapes is shown in Figure 13. Within the Process Cycle, Parameter Sets may
be different or may be reused with the same or different Control Attributes, and similarly the
Shapes may be different or may be reused in different Parameter Sets.

TruFiber P compact (FD44-A/W)
The Laser 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.
A useful feature of FiberView is that if it is run without a Laser connected, then an option is
available to simulate a Laser. This feature is useful for safely familiarising Users with the
operation of the FiberView and for setting up Shapes, Parameter Sets and Process Cycles for
subsequent download to a Laser. When downloaded the Process Cycles may be controlled by
FiberView or directly using the MCIF without FiberView.
FiberView allows different levels of access (Operator, Supervisor and Maintenance) for control
of the Laser in a production environment. Additionally, FiberView can be locked.
Operation of the Laser using FiberView is described in SM-S01071 FiberView and Machine
Control Interface Instructions for Use.

Control System Safety Functions
Overview
The control system provides six safety related functions. These are implemented in electronic
and electromechanical circuits and have been designed and validated to defined safety
performance levels, as specified in ‘BS EN ISO 13849-1:2015. Safety of machinery. Safetyrelated parts of control systems. General principles for design.’ These functions are monitored
by the control system and reported via FiberView. The functions are as follows.
5.4.2
Prevention of Unauthorised Use
This is provided by the key switch on the front panel. The Laser can only be operated when the
key is in the ON position. The key is captive in the ON position and can only be removed in the
OFF position. The key switch is part of a dual channel category 4 circuit with safety relay.
5.4.3
Prevention of Unexpected Start-Up
This is provided by a dual channel category 4 circuit with safety relay and the RESET pushbutton
on the front panel. The RESET button must be pressed after any of the following events:
•
the electrical supply is switched on
•

Unpacking the Beam Delivery Optic
Take care not to twist the conduit when uncoiling the BDO. Always unroll the conduit from the
free end, compensating for any twist that might occur. The conduit is very flexible and easily
bent when uncoiling. 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
uncoiling the beam delivery optic as there is a tendency for the coil to spring apart: this may
cause the optical connector to collide with other objects. Do not drop the optical connector or
allow it to hit surfaces or other objects.
Finally remove the optical connector from the foam block by pushing the connector out of the
block. Use a finger inserted in the top of the block to push against the protective cap on the
optical connector.
Do not pull the block off as the protective cap may be inadvertently removed from the optical
connector exposing the window to contamination.

7 Installation
7.1
Safety and Compliance During Installation
CAUTION: This TruFiber Laser is heavy and so precautions must
be taken when lifting and moving.
Failure to do so may cause serious injury.
This Laser is heavy. To avoid the risk of personal injury or damage to the Laser when lifting or
moving, lift with two people and use a trolley or similar mechanical assistance when moving
over distance.
Before installation reference should be made to Section 3 regarding laser safety, electrical
safety, EMC and compliance. When installed, the Laser and the additional equipment required
to operate it should not obstruct access to safety devices or impair their operation.
It is recommended that installation is done in the sequence of the following sections, with water
connections made and checked before electrical connections are made.
7.2
Location and Environment
Water cooled Lasers are designed for operation within the environment specified in Table 14.
Air cooled Lasers are designed for operation within the environment specified in Table 15.
Operating the Laser beyond the limits of the environmental specification may lead to accelerated
component ageing and performance degradation.
With water-cooled Lasers care must be taken to ensure that they are always operated above
the dew point so that internal condensation is avoided. Refer to Figure 44 Environmental
Conditions for Non-Condensing Operation for a chart showing the relationship between relative
humidity, ambient air temperature and cooling water temperature for non-condensing operation.
To reduce the risk of internal condensation, should the cooling water temperature fall below the
dew point, the Laser automatically regulates the flow of cooling water to keep the internal
surfaces above the dew point.
This Laser should not be installed in a corrosive atmosphere.
This Laser should not be exposed to high levels of optical radiation, for instance radiation from
materials processing.
This Laser is sealed against dust and water ingress to IP52 to BS EN 60529:1992+A2:2013
with the exception of the electrical connectors which are rated IP50 and the fan pack on air
cooled Lasers. The Laser Integrator should ensure that when installed the Laser is not likely to
be exposed to water, for instance from cooling water leaks.
At least 200mm clear space must be provided in front of and behind the Laser to allow the BDO
and electrical cables to be routed correctly. For air cooled Lasers, the BDO and electrical cables
must be routed to avoid obstructing the airflow.

The optical connector shall be mounted in a protective housing which prevents human access
to laser radiation (including errant radiation) in excess of the AEL for class 1, for example a
housing meeting the requirements of EN 60825-4. The protective housing shall withstand
exposure under reasonably foreseeable single fault conditions without human intervention.
7.3
Mounting
The total weights of Lasers of different rated powers are given in Table 24 and Table 25
Table 24. The front panels of water cooled Lasers range from 4U to 6U, and air cooled Lasers
are 5U, enabling them to be fitted into standard 19” rack cabinets.
Mounting options for water cooled Lasers are given in FS-S00138, TruFiber 300W to 1.5kW
Fiber Laser Installation Drawing, and for air cooled Lasers in FS-S00165, TruFiber 300W to
500W Air Cooled Fiber Laser Installation Drawing.
The 2kW water cooled laser installation instructions can be found in FS-S00172
Ensure that the conduit carrying the delivery fiber is not kinked or snagged. Follow the guidance
given in SM-S01072 and allow sufficient space for correct routing of the conduit. Failure to do
so may result in permanent damage to the delivery fiber.
7.4
Cooling Water Connections (Water Cooled
Lasers)
CAUTION: Ensure an approved overpressure safety device is
installed when connecting this TruFiber Laser to an external chiller
or factory water supply. This should comply with ISO4126-1 (or
equivalent) and be rated to protect the TruFiber Laser against a
flow or differential water pressure in excess of that specified in
Table 19 Cooling Requirements (Connection to Manifold).
CAUTION: If cooling water is allowed to enter this TruFiber Laser
enclosure, do not use the TruFiber Laser and contact TRUMPF
Laser UK immediately.
Failure to do so may result in electrical shock and damage to the
TruFiber Laser.
7.4.1
TruFiber Laser
The Laser must be operated with a source of chilled water as specified in Section 13.3.2 it is
provided with connectors for 12mm diameter (16mm 2kW) tubing at the rear. Tubing should be

routed, observing the specified bend radius, so that any leaking cooling water or condensation
will be kept away from the Laser, and provision should be made to shut down the Laser and
shut off the cooling water flow when a leak is detected.
The Laser includes a solenoid valve on the water inlet which regulates the flow of cooling water,
keeping the internal surfaces above the dew point to prevent condensation. When using a chiller
that does not include an internal bypass valve, a bypass valve may be required to enable
uninterrupted operation of the chiller. Check valves suitable for use as bypass valves are
available in different sizes and with different connection types from Swagelock and other
vendors.
Cooling water connections should be made and checked for leaks before making electrical
connections and powering up the Laser. To avoid potential water ingress the electrical
connectors should be capped while checking for leaks.
In order to fill and prime the Laser, the solenoid valve must be opened. This can be done through
FiberView or by sending a command over one of the serial interfaces.
With the key switch in the OFF position send the command to open the valve. With the valve
open and the chiller connected, switch on the chiller. Switch the chiller off and top up the water
level before operating the Laser for the first time. If an external cooling water leak occurs and
water comes into contact with any of the electrical connectors, allow the Laser to dry completely
before operating.

PIPA-Q Optical Connector
It is essential that the PIPA-Q optical connector is adequately cooled with a source of clean,
chilled water in accordance with the specifications in Table 21 Cooling Requirements
(Connection to PIPA-Q Optical Connector). Operating the PIPA-Q optical connector without an
adequate flow of cooling water may result in catastrophic damage.
The inlet and outlet water connections are SMC MS-5HLH-6 type miniature elbows suitable for
6mm LLDPE or polyurethane tubing.
The cooling circuit of the PIPA-Q optical connector should not be connected in series with the
manifold of the Laser as the solenoid valve will interrupt the flow through the PIPA-Q optical
connector.

PL96 – Single Channel Interlock
PL96 provides a general purpose, single channel interlock, which may be used, for instance, to
prevent water cooled Lasers 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
should not be used to protect Users from laser radiation.

PL5 – Machine Control Interface
The Machine Control Interface (MCIF) of TruFiber Lasers with an FVCU allows total operational
integration of the Laser into a production line or cell. The seven digital inputs and seven digital
outputs are PLC compatible and can be configured using FiberView to perform specific functions
selected from a list of available functions. There is also one analogue input and one analogue
output. The default configuration, given in Table 11, should be suitable for the majority of
applications, but the flexibility allows Laser Integrators to tailor the MCIF to their application.
Some of the inputs and outputs are multiplexed depending on the processing mode. For
example, the same output functions as Laser ON or Process Cycle Start depending on
whether the Laser is processing in Parameter Sets mode or Process Cycle mode.
The Laser can be controlled entirely using the MCIF, but if it is controlled over a serial interface
then the configured outputs are still available, although the MCIF must be provided with 24V to
power the opto-isolators.
Refer to SM-S01071, TruFiber FiberView and Machine Control Interface Operator’s
instructions, for full instructions for controlling Lasers with FiberView and the Machine Control
Interface.
On all Lasers the MCIF connection is made through connector PL5. The MCIF is opto-isolated,
to prevent operational problems caused by ground loops, and requires an external 24V supply
for the outputs to function.

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 CPLD, programmed
independently using different software tools, that conforms to EN ISO 13849-1:2015, (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 PSU is 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 500ms. The EShutter circuits confirm that the pump diode PSU outputs have been discharged to a voltage
which is too low to operate the pump 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.

For pin orientation see Figure 23, Figure 24, and Figure 25
Figure 33 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 should be linked to pin 2 and
pin 3 should 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 PSU safe and PSU ready status outputs. The input
and outputs are isolated from the control circuits, but there is also access to the internal 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 PSU is enabled when the PSU enable input is on.
The PSU 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 PSU 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 PSU takes an
excessive time to enable or disable, this is detected as a fault.
Figure 34 shows connections to a control contact and indicator lamps using 24V DC from the
Laser and Figure 35 shows connections to a PLC using an external 24V DC supply.

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 (PLe). It provides the Remote Interlock required for compliance to
EN 60825-1:2014.
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. A reset is
required 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 reset is
performed either by pressing and releasing the reset button on the front panel or by closing and
then opening the reset circuit on PL91. After a successful reset, the reset button will light up
blue.
For pin orientation see Figure 23, Figure 24, and Figure 25

Routing the Beam Delivery Optic
CAUTION: If damage to the conduit or optical connector is
suspected, stop using the TruFiber Laser and contact TRUMPF
Laser UK immediately.
Failure to do so may result in exposure to harmful levels of
radiation.
BDOs and their 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.
The BDO should be routed carefully following the instructions given in SM-S01072.
7.8 Connecting and Removing the PIPA-Q Optical
Connector to the Process Head
CAUTION: The protective cap placed on the optical connector is intended
to protect the connector from contamination during shipping and when the
Prism 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 Laser with the protective cap in place may result in damage
to the Laser. In addition, due to the elevated temperatures associated with
operating the 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 Laser with the protective tape in place may result in
damage to the 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 PIPA-Q optical connector should be connected and disconnected carefully following the
instructions given in SM-S01072

8.3
Control of Operating Temperature
(Water Cooled Lasers)
It is important that water cooled Lasers are operated above the local dew point (see Section
13.1). A solenoid valve on the cooling water inlet is used to maintain the temperature of the
base plate at the desired value using closed loop control. The temperature is maintained within
±0.5°C of the set point by varying the open and close time of the solenoid valve. The closer the
inlet water temperature is to the set-point, the less frequently the valve will have to operate.
For the most stable operation the water inlet temperature and the temperature set-point should
be the same. The optimum operating temperature will be the lowest value that is above the local
dew point at all times. In certain countries with large variation of dew point over the year, it is
preferable to optimise the set-point for different seasons.
The set point can be adjusted in the range 18°C to 30°C using FiberView.

Alarms and Warnings
Alarms
When the system detects an alarm condition, the Laser goes to the OFF state.
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.
8.4.2
Warnings
A warning is generated by conditions which are of concern, but do not put the Laser into the
OFF state. Warnings are cleared automatically when the condition is removed.
Warning conditions include:
•
Back Reflection approaching alarm level
•
Process cabinet door interlock switch open
•
Temperature(s) approaching alarm level(s)
•

This Laser is sealed against dust and water ingress to IP52 to BS EN 60529:1992+A2:2013
with the exception of electrical connectors, which are rated to IP50. Air Cooled variants of the
laser are rated IP50.
The Laser Integrator should ensure that when installed, the Laser casing is not exposed to
water.
Water must not be allowed to condense on or in the Laser.
Note that auxiliary equipment is required to operate the Laser. The environmental operating
conditions of the auxiliary equipment must be observed.
This Laser should not be installed in a corrosive atmosphere.
This Laser should not be exposed to high levels of optical radiation, for instance laser or other
radiation from materials processing.
For water cooled Lasers, condensation can be avoided by using cooling water at a temperature
appropriate to the local humidity. Figure 44 Environmental Conditions for Non-Condensing

Operation 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, and preferably 30°C, to prevent condensation.
Alternatively, as the Laser includes a solenoid valve which regulates the flow of cooling water
to keep the internal surfaces above the dew point, a cooling water temperature below the dew
point may be used.
Figure 44 Environmental Conditions for Non-Condensing Operation
Water must not be allowed to condense on or in the optics. The dashed and solid lines in Figure
44 cover the permitted cooling water temperatures for the PIPA-Q optical connector and can be
used to determine if the atmosphere is condensing. 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 15°C cooling water curve.
However, if the ambient air temperature is 35°C and the relative humidity is 80% then the cooling
water temperature should be 35°C to prevent condensation.

13.3.2 Cooling Water Requirements (Water Cooled Lasers)
The Laser requires water cooling. The base plate within the body of the Fiber Laser Module has
a cooling circuit. The PIPA-Q optical connector has a separate water cooling circuit.
Requirements for the cooling water are given in Table 18. Permitted temperature ranges and
required flow rates, together with other parameters, for the base plate and PIPA-Q optical
connector are given in Figure 23.

Notes

Drinkable tap water is likely to meet these requirements, and water meeting the requirements
of VDI3803.
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.
•
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, aluminium and plain carbon or
low alloy steels should not be used as galvanic corrosion may occur. Galvanic corrosion
occurs if materials with widely different electrochemical potentials are used. Stainless
steel and insulating materials (polymers) may be 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
•
where there is a need to protect the cooling water from freezing, inhibited ethylene glycol
(ethane-1,2-diol) may be added to it. TRUMPF LASER UK recommends a concentration
of 25% by volume to protect against freezing to -10°C with a minimal drop in thermal
performance while also providing corrosion protection and serving as a bactericide.
•
additives may reduce the heat capacity of the water. The flow rate must be increased to
compensate. Refer to the manufacturers’ instructions and safety information for the use
of additives.

In the unlikely event that the TruFiber Laser requires attention outside the scope of the
maintenance requirements given in Section 9, contact TRUMPF Laser UK for advice on further
on-site fault diagnosis and/or return of the Laser. Contact information is given in Section 15.
When contacting TRUMPF Laser UK, please have the following information at hand:
•
The order code.
•
The serial number.
•
The number of accumulated operating hours.
•
Typical operating parameters.
•
Any other relevant information (e.g. fault codes and descriptions) that would assist in
fault diagnosis.
If the Laser requires fault-diagnosis or servicing or is to be returned to TRUMPF Laser UK, it is
the system integrator’s responsibility to remove the Laser from the integrated laser system and
make it safe and, if the Laser is to be returned to TRUMPF Laser UK, to ensure that all relevant
return documentation is in place before shipment. Details of documentation requirements and
copies can be obtained where required from TRUMPF Laser UK.
Water cooled Lasers must be drained of all cooling water and the bungs fitted to all pipes prior
to shipment. If the Laser is shipped without the bungs fitted then any residual cooling water will
escape during transit and may cause permanent damage.
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 TRUMPF
Laser UK for replacement items. Please take time to complete all return documentation, which
can be obtained from TRUMPF Laser UK. Accurate details, diagnosis and comments in the
documentation reduce turnaround time for repair at TRUMPF Laser UK.
On request, TRUMPF Laser UK will supply a report detailing faults found and repairs carried
out necessary to return the Laser to full operational specification.
