1.3 IMPORTANT HIGHLIGHTED INFORMATION
Important danger, warning, caution and notices are highlighted throughout the manual as follows:
! DANGER
A DANGER symbol indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.
! WARNING
A WARNING symbol indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION
A CAUTION symbol indicates a potentially hazardous situation which, if not avoided, may result in property damage.
NOTICE
A NOTICE symbol indicates important information that must be remembered and aids in job performance.
1.4 CONTROL RELIABILITY
“Control Reliability” means that, “the device, system or interface shall be designed, constructed and installed such that a single
component failure within the device, interface or system shall not prevent normal stopping action from taking place but shall prevent
a successive machine cycle.” (ANSI B11.19-1990, 5.5)
OSHA 29 CFR 1910.217 states that, “the control system shall be constructed so that a failure within the system does not prevent
the normal stopping action from being applied to the press when required, but does prevent initiation of a successive stroke until
the failure is corrected. The failure shall be detectable by a simple test, or indicated by the control system.”
Honeywell has developed a self-checking technique that combines reliability with safety. The FF-SYB Series safety light curtain
functions with dual channel redundancy and positive self-check monitoring. This means that a faulty component in our product will
make the optoelectronic safety device fail in a safe mode.
This design meets the highest safety requirements (type 4) described in the IEC/EN 61496-1 and IEC/ EN 61496-2 norms. Type 4
devices are designed and manufactured in such a way that a single breakdown or an accumulation of failures does not lead to the
loss of the safety function when a dangerous situation arises. The safety function is maintained on a permanent basis.

DESCRIPTION AND OPERATION
2.1 OVERVIEW
This chapter contains terms and concepts related to safety and the application of the FF-SYB Series light curtain. The importance
of the installer’s role in the set-up and installation of the machine guarding systems is discussed. The section also contains
specification and order guide information.
2
Remark:
In order to simplify this manual, the term “safety light curtain” is used for the FF-SYB14, FF-SYB30 and FF-SYB50 safety light
curtains as well as for the FF-SYB234 safety multibeam systems for access detection.
2.2 MACHINE GUARDING AND PERIMETER PROTECTION
The FF-SYB14 and FF-SYB30 Series through-scan light curtains are non-contact machine guarding devices designed for point-ofoperation protection at power driven machinery (see Figure 2-1) where fingers or hands need to be detected.
The FF-SYB50 Series light curtains are designed for presence detection in dangerous areas where legs or a body need to be
detected.
The FF-SYB234 Series multibeam systems are used for access detection in dangerous areas where a body needs to be detected.
! WARNING
IMPROPER INSTALLATION OF FF-SYB SERIES LIGHT CURTAIN
• Install FF-SYB light curtains in accordance with this installation manual and applicable local safety regulations (OSHA,
ANSI, European standards).
• Allow entry into protected area by interruption of sensing field of the safety light curtain or activation of another safeguarding
device only.
Failure to comply with these instructions could result in death or serious injury.
FF-SYB Series light curtains generate a stop signal if the sensing field is interrupted. Further operation is prevented until the
sensing field is cleared. The FF-SYB Series light curtain monitors itself continuously for component failures, misalignments, and
dirt accumulation. Small misalignments or dirt accumulation are indicated by a flashing LED. If misalignment or dirt accumulations
become too great or a component fails, a stop signal is generated. Operation is prevented until the condition is corrected.
! WARNING
IMPROPER SYSTEM PERFORMANCE
• Comply with local safety requirements when designing machine control link, interface and all control elements that affect safety.
• Install two independent safety relay contacts into machine control stop circuit controlled by FF-SYB Series light curtain.
• Ensure two independent stop circuit relays have mechanically linked contacts to reliably detect a welded contact.
• Using one of the compatible safety relay modules (see chapter 6) will provide safe relay contacts to the machine control stop
circuit.
Failure to comply with these instructions could result in death or serious injury.
FF-SYB Series light curtains are designed so a malfunction or an interruption of the sensing field will immediately cause the light
curtain to generate a stop signal. This stop signal will be generated automatically if a malfunction occurs in the light curtain. All
other machine control components that affect safety should also be designed to the same high level of operation.
! WARNING
IMPROPER MACHINE REACTION
• Ensure the machine control is capable of stopping the machine at any point in the cycle.
• Ensure that a loss of power does NOT impair stopping action of machine.
Failure to comply with these instructions could result in death or serious injury.
! DANGER
FULL REVOLUTION MECHANICAL POWER PRESSES CANNOT BE STOPPED IN MID-STROKE (OSHA 29CFR 1910.217)
DO NOT use FF-SYB Series light curtains on full revolution mechanical power presses.
Failure to comply with these instructions will result in death or serious injury.
8
107120-20-EN FR26 GLO 804 Printed in France
For point-of-operation guarding, the light curtain(s) and any mechanical guards should be installed so no one can stand between
the light curtain and the danger zone. This may require additional hard guarding, horizontal or angled positioning of the light
curtain, or additional light curtains.

! WARNING
IMPROPER PERIMETER PROTECTION ACTIVATION
• Design control circuit that requires a manual restart before further machine operation can occur.
• Locate manual restart to allow operator a clear view of danger zone.
• Operator must NOT be able to reach manual restart from within danger zone.
• Design control circuit to prevent Programmable Logic Controller from overriding manual restart.
Failure to comply with these instructions could result in death or serious injury.

2.4 OPERATION
The FF-SYB Series are through-scan light curtains. Emitters transmit modulated, infrared light that is detected by photoreceivers
in the receiver. The number of light beams depends on the protected height and resolution of the light curtain.

Receiver
2.4.1 SYNCHRONISATION
The emitter and the receiver are optically synchronised. The synchronisation is an effective beam transmitted by the emitter
towards the receiver. No electrical connection is necessary between the emitter and the receiver that simplifies installation and
maintenance.
2.4.2 RESOLUTION (FF-SYB14, FF-SYB30 AND FF-SYB50 SERIES)
FF-SYB Series light curtain resolution (sometimes called minimum object sensitivity) is the minimum object size that will interrupt
at least one light beam when it enters the sensing field. Anything entering the sensing field equal to or greater than this minimum
size will be detected. Resolution is not affected by scanning distance or dust accumulation. Two factors determine the resolution of
the light curtain: beam pitch and light lens diameter (see Figure 2-5).
Lens diameter is the smallest width that will block a single light beam. The combination of the beam diameter and centre distance
gives the FF-SYB14 a resolution of 14 mm (0.6 in), the FF-SYB30 a resolution of 30 mm (1.2 in) and the FF-SYB50 a resolution of
50 mm (1.97 in).
! WARNING
RESOLUTION AND FLOATING BLANKING
• Resolution is affected by the floating blanking.
• Refer to chapter "Floating blanking" to determine proper resolution.
Failure to comply with these instructions could result in death or serious injury.

2.4.3 FLOATING BLANKING
The built-in floating blanking feature provides a means for the random inhibition of one or two beams of the light curtain except the
synchronisation beam. It is useful in those applications where material or air ejected parts randomly travel through or within the
sensing field. You can also disable light beams in an area where a fixture penetrates the light field, and you can permit stationary
objects to protrude into the light curtain's sensing field. Floating blanking may only be used when material or parts take up a space
no greater than the maximum value in the table below within the sensing field. Larger material would block more than one light
beam at a time. As a result, the light curtain would generate a stop command.
When using floating blanking, the resolution of the light curtain is altered according to the following table:

NOTICE
The floating blanking IS NOT available with the 2-beam and 3-beam FF-SYB234 systems. Select the 4-beam FF-SYB234 system
if this feature is required.
Anything smaller might fit between two light beams.
Floating blanking blocks one or two light beam(s), creating an additional passageway through the light field where no object will be
detected. Safety distance formulas state that if the resolution increases, the safety distance must also increase.
This means that use of a blanking will require moving the light curtain farther back from the hazardous area.
However, if the area blanked is entirely blocked by a fixture such that operator intrusion into this area is impossible, then you do not
have to change the safety distance. For instance, you might have a work table that juts out into the light field but takes up the whole
space between the emitter and receiver that is blanked and therefore unprotected by the light curtain.
You can enable this feature by selecting the corresponding configuration card. Two yellow indicators at the receiver provide an
indication on floating blanking status. If you use this feature, even occasionally, the safety distance for mounting must be increased.
Refer to "Calculating Safety Distance" in chapter "How to calculate safety distance of this manual".
! WARNING
INCORRECT SAFETY DISTANCE WHEN USING FLOATING BLANKING
• Ensure that the correct safety distance exists between the light curtain and the hazardous area.
• See chapter "How to calculate safety distance" for detailed information on resolution and calculating the safety distance.
Failure to comply with these instructions could result in death or serious injury.
The next illustration shows how coil stock cuts different light beams as the coil unwinds. As long as only one or two beams are cut
at a time (no matter which one it is), the FF-SYB safety light curtain continues to allow machinery to operate.

NOTICE
NON COMPLIANCE TO ANSI/RIA 15.06-1999 WITH FF-SYB02500
• Only the three beam FF-SYB03400 (-L) and the four beam versions FF-SYB04300 (-L) are in compliance with the beam
heights, specified in the US Standard ANSI/RIA R15.06-1999 (Industrial Robots and Robot Systems - Safety Requirements).
The two beam version FF-SYB02500 (-L) does NOT comply with ANSI/RIA R15.06 and may require additional protection.
• Refer to applicable standards. In the absence of an applicable standard, ANSI B11.19 and ANSI R15.06 may be used as
reference for the USA, as well as EN 999 (or the relevant European Type C machine standard) for Europe.
• Verify compliance with ANSI/RIA R15.06 and possibly implement additional protection when floating blanking is used on the
4-beam FF-SYB234 system.
2.4.6 SCANNING RANGE
The scanning range is the maximum distance allowed between the emitter and the receiver. A configuration card is used on the
emitter unit for the selection of the adequate emission power. Refer to the chapter "Mutual Interference or cross-talk" for correct
adjustment.
NOTICE
CONFIGURATION CARD SETTINGS
The configuration card in use for the selection of the

! WARNING
MINIMUM SCANNING RANGE (FF-SYB14, FF-SYB30 and FF-SYB50 only)
Using the FF-SYB14, FF-SYB30 or FF-SYB50 light curtains below the specified minimum scanning range will maintain the light
curtain in a lock out condition. To go back to normal conditions of operations, switch the power off, move away the receiver from
the emitter, then restore the power.
Failure to comply with these instructions could result in death or serious injury.
! WARNING
2
IMPROPER MINIMUM SCANNING RANGE (FF-SYB234 only)
Always install the FF-SYB234 multibeam systems at a distance superior to the minimum value of the selected scanning range or select
a lower scanning range on the emitter. When installed at a distance below the specified minimum scanning range, the FF-SYB234
multibeam systems for access detection may NOT comply with IEC/EN 61496-2 optical requirements for aperture angle.
Failure to comply with these instructions could result in death or serious injury.
See chapter "Configuration cards" for scanning range settings.
2.4.7 MANUAL RESTART
The FF-SYB can be used in automatic or manual restart mode. In automatic mode, the outputs will switch back to ON after an
interruption of the protection field, as soon as the field becomes clear again. In manual restart mode, the FF-SYB will not switch
back its outputs to ON until a manual restart push-button is pressed and reset. The push-button must be a normally open type
button. The manual restart will not switch the OSSDs back to ON in case of light curtain lock out (internal failure, light interference,
etc.) or when the protection field is interrupted.
This feature is enabled by selecting the corresponding configuration card.
2.4.8 EXTERNAL DEVICE MONITORING (EDM)
The FF-SYB is fitted with an EDM input which allows users to check the correct state of the final switching devices (relays, contactors,
etc.). After each intrusion into the protection field, the FF-SYB will check that the EDM input loop is closed before switching the
outputs back to ON. If the FF-SYB operates in automatic restart mode, it will restart immediately if the EDM loop is closed. If the
FF-SYB operates in manual restart mode, it will restart when the restart push-button is pressed and if the EDM loop is closed. If the
EDM loop remains open (meaning that the external device has a malfunction) the FF-SYB will keep its outputs open and will not
restart.
2.4.9 MUTING FUNCTION
Muting is the ability to temporarily inhibit the outputs of a light curtain under certain conditions. The FF-SYB is fitted with a built-in
muting function. Sensors are connected to the light curtain through the main connector, optional junction boxes are available to
perform the electrical connections close to the location of the muting sensors.
Muting sensors are used to discriminate authorised materials from people. The muting sensors must be able to detect the passing
material (pallets, vehicles, etc.) according to the material's length and speed.
The muting activation sensors temporarily inhibit the safety light curtain if a package is detected by the sensors. The outputs of
these sensors are connected to the muting inputs of the receiver unit of the FF-SYB. Muting sensors must be actuated within a time
period of 3 s for a correct muting sequence to start.
! DANGER
MECHANICAL POWER PRESS OPERATING IN REVERSE MODE
• The Honeywell muting function shall only be used during non-hazardous portion of the mechanical power press cycle, i.e.
during die opening when the press is running forward (crankshaft is running clockwise).
• If it is foreseeable that the press may be run in reverse or the press crankshaft rotation direction changed, even accidentally,
DO NOT install the Honeywell muting system on the press.
• The muting function provided by the Honeywell product DOES NOT recognize the crankshaft rotation direction (clockwise or
counterclockwise). If muting is installed to operate during the upstroke when running forward (clockwise), then muting should
not occur during the downstroke when running reverse (counterclockwise). Muting is ONLY permitted during the upstroke (die
opening portion of the cycle).
Failure to comply with these instructions will result in death or serious injury.
In case of an incorrect muting sequence, a temporary manual muting procedure may be performed to clear the FF-SYB light
curtain detection field and revert back to normal operation (see chapter "Temporary Manual Muting function (TMM)" for details).
14
107120-20-EN FR26 GLO 804 Printed in France
2.4.10 SERIAL CONNECTION
The FF-SYB safety light curtain allows the connection of an auxiliary safety device with dual outputs through 2 inputs on the
receiver unit. Connection is done through the main connectors. Optional junction boxes are available to perform the electrical
connections close to the light curtain.
NOTICE
The auxiliary safety device may be an electromechanical safety switch or any other safety device with either relay outputs or solid
state outputs. For safety reasons, reversed polarity on these two inputs is mandatory, therefore connection of a second FF-SYB
light curtain is not possible through these two inputs.
In this mode, the FF-SYB expects both outputs of the connected sensor to be ON in order to turn on its outputs. If one or both
outputs of the connected safety sensor go off, the FF-SYB will switch off its outputs within 22 ms.

2.4.11 CONFIGURATION CARDS
The FF-SYB is set in the required configuration through the use of configuration cards. This simple and elegant method eliminates
the use of jumpers or dip switches. No computer is required: settings are done on site, using one of the small configuration cards.
If the user needs to use a different configuration from the factory settings, he just needs to select the configuration card which
corresponds to the desired settings and install it behind the bottom cap of the emitter or receiver.
If the FF-SYB needs to be exchanged, the configuration card can be installed in another FF-SYB allowing transfer of settings in a
few minutes.
! WARNING
NOTICE
Remove power before changing cards (otherwise the light curtain remains in a lock-out condition after changing card).
Activities detected on inputs that are not configured by the selected configuration card, will set the FF-SYB light curtain into a
lock-out condition. Remove power, insert the proper configuration card and restore power to return to normal operation.

INSTALLATION
3.1 OVERVIEW
This chapter contains information about calculating the safety distance and properly mounting a safety light curtain. Mirror information is also provided.
! DANGER
FULL REVOLUTION MECHANICAL POWER PRESSES CANNOT BE STOPPED IN MID-STROKE (OSHA 29CFR 1910.217)
DO NOT use FF-SYB Series light curtains on full revolution mechanical power presses.
Failure to comply with these instructions will result in death or serious injury.
! DANGER
MECHANICAL POWER PRESS OPERATING IN REVERSE MODE
• The Honeywell muting function shall only be used during non-hazardous portion of the mechanical power press cycle, i.e.
during die opening when the press is running forward (crankshaft is running clockwise).
3
• If it is foreseeable that the press may be run in reverse or the press crankshaft rotation direction changed, even accidentally,
DO NOT install the Honeywell muting system on the press.
• The muting function provided by the Honeywell product DOES NOT recognize the crankshaft rotation direction (clockwise or
counterclockwise). If muting is installed to operate during the upstroke when running forward (clockwise), then muting should
not occur during the downstroke when running reverse (counterclockwise). Muting is ONLY permitted during the upstroke (die
opening portion of the cycle).
Failure to comply with these instructions will result in death or serious injury.
! WARNING
IMPROPER INSTALLATION OF FF-SYB SERIES LIGHT CURTAIN
• Install FF-SYB Light Curtains in accordance with this installation manual and applicable local safety regulations (OSHA, ANSI,
European standards).
• Allow entry into protected area by interruption of sensing field or other safeguarding device only.
Failure to comply with these instructions could result in death or serious injury.
! WARNING
IMPROPER SYSTEM PERFORMANCE
• Comply with local safety requirements when designing machine control link, interface and all control elements that affect safety.
• Install two independent safety relay contacts into machine control stop circuit. These safety relays shall be cross-monitored to
ensure static (solid state) safety operation.
• Ensure two independent stop circuit safety relays have mechanically linked contacts to reliably detect a welded contact.
• Using one of the safety relay modules (see chapter 6) will provide safety relay contacts to the machine control stop circuit.
Failure to comply with these instructions could result in death or serious injury.
! WARNING
IMPROPER MACHINE REACTION
• Ensure the machine control is capable of stopping the machine at any point in the cycle.
• Ensure that a loss of power does NOT impair stopping action of machine.
Failure to comply with these instructions could result in death or serious injury.
3.2 POINT-OF-OPERATION GUARDING
! DANGER
IMPROPER POINT-OF-OPERATION INSTALLATION.
• Do NOT use the FF-SYB234 multibeam systems or the FF-SYB50 light curtains for point-of-operation guarding. Use the
FF-SYB14 or FF-SYB30 light curtains only.
• DO NOT allow an operator to stand undetected between the light curtain and the machine when using FF-SYB Series safety
light curtains for point-of-operation guarding.
Failure to comply with these instructions will result in death or serious injury.
Point-of-operation is defined as that area where a machine performs work (such as cutting, shaping, boring, or forming) on a
material. For point-of-operation guarding the FF-SYB14 and FF-SYB30 safety light curtain(s) and any mechanical guards must be
installed so no one can stand undetected between the light curtain and the dangerous machine zone. Additional hard guarding,
interlocked guarding, light curtain or safety mats may be required.

3.3 PERIMETER GUARDING
! WARNING
IMPROPER INSTALLATION OF FF-SYB SERIES PERIMETER DEVICE
• Install the FF-SYB234 multibeam systems or the FF-SYB50 light curtain in accordance with this installation manual and
applicable safety regulations and standards (OSHA, ANSI, European standards).
• Only allow entry into protected area by interruption of sensing field or other safeguarding device.
Failure to comply with these instructions could result in death or serious injury.
! WARNING
IMPROPER PERIMETER PROTECTION
• Design control circuit to allow a manual restart before further machine operation can occur.
• Locate manual restart outside of danger zone where operator has a clear view of zone.
• Operator should NOT be able to reach manual restart from within danger zone.
• Design control circuit to prevent Programmable Logic Controller from overriding manual restart.
Failure to comply with these instructions could result in death or serious injury.
3
Honeywell's FF-SYB234 multibeam systems and the FF-SYB50 are self-contained, perimeter protection devices designed to
detect the body of an operator before gaining access to a dangerous area. After the detection of a body, the machine must stop and
remain stopped until the operator performs a manual restart outside the danger zone.
3.4 HOW TO CALCULATE SAFETY DISTANCE
! DANGER
INCREASED SAFETY DISTANCE DUE TO FLOATING BLANKING
Modify the safety distance between the light curtain and the hazardous area according to the instructions in this chapter.
Failure to comply with these instructions will result in death or serious injury.
The safety distance is the minimum distance between the sensing field and the danger zone. This distance ensures that the danger
zone cannot be reached until the machine motion has been stopped.
3.4.1 SAFETY DISTANCES PER EUROPE’S EN 999 STANDARD
In Europe, calculate the safety distance (see Figure 3-1) using the following formula:
S ≥ V (t1+ t2) +C
Where:
• S is the safety distance from the light curtain sensing field to the danger zone
• V is the velocity of movement into the danger zone
• t1 is the response time of the FF-SYB light curtain.
• t2 is the stopping time of the equipment guarded by the light curtain including interconnecting components such as all mechanical,
electromechanical, and electronic parts such as relays, solenoids, and brakes.
• C is additional safety distance.

3.4.2 SAFETY DISTANCES PER USA'S OSHA/ANSI REQUIREMENTS
In the USA, calculate the safety distance (see Figure 3-1) using the following formula:
Ds ≥ K (Ts+Tc+Tr) + Dpf
Where:
• Ds is the minimum safety distance from the light curtain sensing field to the danger zone
• K is the approach speed of movement to the danger zone
• Ts is the worst case stopping time of the machine
• Tc is the worst case response time of the machine's control
• Tr is the response time of the safety devices (light curtain plus its interface - meaning the response time including the mechanical
relay outputs)
• Dpf: Depth penetration factor

! WARNING
IMPROPER USE OF FF-SYB234 MULTIBEAM SYSTEMS
Do not use the FF-SYB234 multibeam systems in parallel or angled approach applications. Use the FF-SYB234 only in normal
approach applications.
Failure to comply with these instructions could result in death or serious injury.
! WARNING
IMPROPER SAFETY DISTANCE
• Calculate safety distance using formula Ds =K x (Ts + Tc + Tr) + Dpf (see explanations above)
• Ds is the minimum safety distance from the light curtain sensing field to the danger zone (OSHA 29 CFR 1910.217 (c) (3) (iii)
(e) and ANSI B11.1, B11.2, B11.19, and R15.06)
• The Depth penetration factor Dpf is determined by both the installation of the product as well as the product's resolution
(Minimum Object Sensitivity).
Failure to comply with these instructions could result in death or serious injury.
! WARNING
IMPROPER PROTECTIVE HEIGHT
• For 'Reach Thru" applications, the light curtain's protective field must be sufficiently great such that personnel can not reach
over or under the light curtain without being detected.
• The protective height is determined by the installation, measuring from the reference floor to the top beam.
• A protective height of 48 in may be adequate to detect personnel reaching through the curtain light field. Reference ANSI
R15.06 Annex B - supplemental information
• The installation may require a protective height greater than 48 in to properly safeguard personnel due to their height or working
position (standing or sitting) or work station position relative to variations in floor elevations (or work platforms or stairs).
• Before use, verify that the protective heights are adequate for their intended use of safeguarding personnel.
Failure to comply with these instructions could result in death or serious injury.
NOTICE
NON COMPLIANCE TO ANSI/RIA 15.06-1999 WITH FF-SYB02500
• Only the three beam FF-SYB03400 (-L) and the four beam versions FF-SYB04300 (-L) are in compliance with the beam
heights, specified in the US Standard ANSI/RIA R15.06-1999 (Industrial Robots and Robot Systems - Safety Requirements).
The two beam version FF-SYB02500 (-L) does NOT comply with ANSI/RIA R15.06 and may require additional protection.
• Refer to applicable standards. In the absence of an applicable standard, ANSI B11.19 and ANSI R15.06 may be used as
reference for the USA, as well as EN 999 (or the relevant European Type C machine standard) for Europe.
• Verify compliance with ANSI/RIA R15.06 and possibly implement additional protection when floating blanking is used on the
4-beam FF-SYB234 system.

3.5 HOW TO CALCULATE MINIMUM DISTANCE CONSIDERING REFLECTIVE
SURFACES
! WARNING
REFLECTIVE SURFACES
• To prevent two optical paths to the receiver, install the FF-SYB light curtains so there are no reflective surfaces within the beam
angles of the emitter and receiver.
• Calculate reflective minimum distance using formula D= L(tan 2,5°), where:
D is the minimum distance to reflective surface (always greater than 131 mm or 5.16 in)
L is the installed scanning range
Failure to comply with these instructions could result in death or serious injury.
Reflective surfaces near the sensing field can cause reflection of the sensing beams and result in two optical paths to the receiver.
The light curtain must be installed so there are no reflective surfaces within the beam angles of the emitter and receiver.
Figure 3-2 illustrates the beam angles.
Calculate the reflective minimum distance using the following formula:
• D = 131 mm, for scanning distances between 0 and 3 m
3
• D = L x tan 2,5°, for scanning distances greater than 3 m
• D = Minimum distance to reflective surface (always greater than 131 mm or 5.16 in)
• L = Installed scanning range
The emitter and receiver must have the same protected height and resolution. The emitter and receiver must be mounted at the
same height and aligned with each other.

3.6 MUTUAL INTERFERENCE OR CROSS-TALK
The FF-SYB Series light curtain is based upon an infrared transmission between an emitter unit and a receiver unit. It is a safety
requirement of the IEC/EN 61496-2 standard that if a receiver R2 receives two signals transmitted by two different emitters E1 and
E2, the receiver R2 must turn to the alarm state. This happens if the receiver R2 is within the 2,5° beam aperture angle and within
the scanning range of the second emitter E1, and the cross-talk detection indicator flickers to warn the installer.
NOTICE
MUTUAL INTERFERENCE OR CROSS-TALK
Reception of two infrared emissions will maintain the light curtain in a lockout condition. To go back to normal operation, switch
the power off and eliminate the interferences by reversing systems emitting orientation or by using opaque screen, or by adjusting
the adequate emission power regarding the application. Then, restore the power.

3.8 MOUNTING CONSIDERATIONS
This section discusses optical alignment and mounting considerations. There are several different ways to mount the FF-SYB
Series light curtains (singularly, in groups, and in several different orientations).
3.8.1 OPTICAL ALIGNMENT
Proper optical alignment of the FF-SYB Series light curtains ensures optimum operation. The emitter and receiver units must be
mounted in parallel, at the same height, and with an angular displacement of no more than ±2,5°. See figure below for proper
alignment.

! WARNING
IMPROPER INSTALLATION OF FF-SYB SERIES LIGHT CURTAIN
• Mount FF-SYB Series light curtains so that any entry into protected area must interrupt sensing field of the safety light curtain
or activate other safeguarding devices.
• Install mechanical guards or additional FF-SYB light curtains to prevent operating personnel from reaching around, under, or
over the sensing field.
Failure to comply with these instructions could result in death or serious injury.

being detected.
• DO NOT use FF-SYB50 Series light curtains or FF-SYB234 multibeam systems for point-of-operation applications.
Failure to comply with these instructions will result in death or serious injury.
3.8.3 VERTICAL MOUNTING / LINEAR ASSEMBLY
NOTICE
MUTUAL INTERFERENCE
When two emitter/receiver units are mounted together to obtain a greater protected height, the emitter and receiver units must be
mounted in a reverse transmitting position to prevent mutual interference. Reception of two infrared emissions will maintain the
light curtain in a lockout condition. To go back to normal operation, switch off and on the light curtain power.
Two emitter/receiver units may be mounted together to obtain a greater protected height (see Figure 3-12). The units may be
mounted with the overlapping housings to maintain the resolution throughout the protected height.

NOTICE
MUTUAL INTERFERENCE
When two or more light curtain systems are installed on adjacent machines, optical interference may occur if two units are within
the field of view. Mutual interference between light curtains can be eliminated by reversing systems emitting orientation, or by
using opaque screens, or by adjusting the adequate emission power regarding the application. A selector switch is available on
the emitter unit for this purpose. Reception of 2 infrared emissions will maintain the light curtain in a lockout condition. To go back
to normal operation, switch off and on the light curtain power.

If the beams of two adjacent light curtains are reversed, no interference will occur between these two light curtains. If more than two
light curtains are installed side by side, then some of them may interfere together. In the above example, Receivers 2 and 3 may
respectively receive a signal from the emitters 4 and 1. An opaque screen can be used between emitter 2 and emitter 3 to solve this
mutual interference problem. However, a different configuration card may be used on emitters 4 and 1 to reduce the effective
scanning range and solve this problem in a smart manner (see "Mutual Interference or cross-talk").

! WARNING
IMPROPER INSTALLATION FOR POINT-OF-OPERATION
To prevent operating personnel from access to danger zone, install hard guard or right-angle mounting if distance between
danger zone and closest light beam is greater than 70 mm / 2.8 in.
Failure to comply with these instructions could result in death or serious injury.
For point-of-operation guarding, the safety light curtain(s) and any hard guarding must be installed so that no person can stand
between the light curtain and the danger zone without being detected. Installation may require additional hard guarding, horizontal
or diagonal mounting of the light curtain, or additional light curtains mounted at right angles to each other.

3.9 MUTING SENSORS
3.9.1 MUTING FUNCTION
3
The muting function enables the inhibition of the safety light curtain during certain stages of operation, the OSSD outputs remaining active.
This function is particularly suitable when objects have to pass through the FF-SYB protection field, under certain conditions.
It is important to remember that the muting function is a forced situation for the system; therefore, it should be used with necessary
precautions.
Two or four muting sensors are connected to the inputs; these sensors must be correctly connected and positioned, in order to
avoid undesired muting or potentially hazardous conditions for the operator.
For example, on a machine automatically fed by a conveyor, parts must be vehiculed through the detection field of the safety light
curtain towards the dangerous area without causing the immediate stoppage of the machine. Similarly, manual loading and unloading
of a machine may be allowed while the machine tool goes back to its home position.
When the protective equipment is not muted, any intrusion of an object or a person inside the FF-SYB detection field immediately
stops the machine.
The muting sequence is controlled by two or four sensors (such as photelectric controls, limit switches or inductive proximity
sensors) which reliably detect the manufactured part or the tool initiating and interrupting the muting sequence.
When sequence conditions are met, the FF-SYB allows the machine to operate during the muting sequence. Correct operation of
the sensors is monitored at each muting sequence and any sensor failure prevents the muting from being performed. If manufactured
parts remain accidentally in the light curtain detection field during a muting sequence, a temporary manual muting of the light
curtain and restart of the machine is easily achieved (see chapter "Temporary Manual Muting (TMM)"). An optional muting indicator
informs the operator of each muting sequence.
3.9.2 INSTALLATION OF THE MUTING SENSORS
The muting sensors must be able to recognize the passing material (pallets, vehicles, etc.) according to the material's length and speed.
NOTICE
IMPROPER MUTING DURATION
In the case of different transportation speeds in the muting area, it is necessary to consider their effect on the total muting
duration.
SM INPUTS (START OF A MUTING SEQUENCE)
At least two auxiliary sensors are necessary to start a muting sequence. These two sensors may be ultrasonic sensors, photoelectric
controls, limit switches or inductive proximity sensors with relays or static (solid state) NPN or PNP (the FF-SYB automatically
recognises the type of sensor output). 2-wire sensors are also accepted. Correct operation of these sensors is monitored by the
FF-SYB and a muting sequence is allowed if both sensor outputs switch ON within a time frame of 3 seconds.
! DANGER
IMPROPER MUTING SENSOR POSITION
• The muting sensors must be positioned in such a way that the activation of the muting function is not possible with the
accidental passing of a person.
• The additional mechanical guardings must be designed and installed in such a way that people cannot enter the dangerous area
without being detected by the safety light curtain and the auxiliary sensors, if relevant. In particular, a person following parts
vehiculed towards the dangerous zone must be detected when interrupting the safety light curtain detection field. The design and
the installation of these additional mechanical guardings must comply with the requirements of the corresponding standards.
• Moreover, it may be necessary to provide additional protection to maintain the protection level provided by the safety light curtain.
Hard guards or additional presence sensing devices such as safety mats, may be used to ensure the operator is either forced to
move through the sensing field to enter the danger zone, or forced to stand on the sensing area inside the danger zone.
Failure to comply with these instructions will result in death or serious injury.
38
107120-20-EN FR26 GLO 804 Printed in France
NOTICE
SENSOR FAILURE
• If a sensor SM fails, the muting sequence is not allowed. In this case the muting indicator remains permanently off.
• Clearing the detection field can be achieved by using the temporary manual muting (TMM) procedure. Upon TMM completion,
the FF-SYB will then operate in guard only mode. And the next muting sequence will not be allowed.
• Normal operation can be achieved by switching the power off, replacing the defective SM sensor, switching the power on and
restarting the product.
EM INPUTS (END OF MUTING SEQUENCE)
Two auxiliary sensors are necessary to stop a muting sequence. These two sensors may be ultrasonic sensors, photoelectric
controls, limit switches or inductive proximity sensors with relay or static (solid state) PNP or NPN output (the FF-SYB automatically
recognizes the type of sensor output). 2-wire sensors are also accepted. Correct operation of these sensors is monitored by the
FF-SYB.
NOTICE
SENSOR FAILURE
• If a sensor EM fails, the muting sequence is not allowed. In this case the muting indicator remains permanently off.
• Clearing the detection field can be achieved by using the temporary manual muting (TMM) procedure. Upon TMM completion,
the FF-SYB will then operate in guard only mode. And the next muting sequence will not be allowed.
• Normal operation can be achieved by switching the power off, replacing the defective EM sensor, switching the power on and
restarting the product.
The muting sequence stops whenever the first EM is desactivated.

The following example is a variation of the previous application, where 4 sensors are used to start a muting sequence whatever the
direction of the movement of the objects. These sensors could also be limit switches, ultrasonic sensors, photoelectric controls or
inductive proximity sensors (correct operation of these sensors is monitored by the FF-SYB). The muting of the FF-SYB is allowed
when the detected objects enter and leave the dangerous area. This installation is recommended on applications where the entry
and exit points of the material into the dangerous zone are the same.

3.9.5 ONE-WAY MUTING ON A CONVEYOR USING 4 SENSORS
In the following example, two thru-scan (or retro-polarized) photoelectric controls SM1 & SM2 are used to start the muting sequence,
and two additional thru-scan (or retro-polarized) photoelectric controls EM1 & EM2 are used to stop it. These sensors could also be
ultrasonic sensors, inductive proximity sensors or limit switches (correct operation of these sensors is monitored by the FF-SYB).
This installation enables the muting of the protective equipment in one direction only. It is recommended on applications where the
entry and the exit points of the material into the dangerous zone are different. The use of 4 sensors to perform a muting sequence

! WARNING
IMPROPER INSTALLATION
The distance between SM1 & SM2 sensors must not allow a person to actuate both sensors within the preset time frame (3 sec)
to avoid the unexpected start of a muting sequence.
Failure to comply with these instructions could result in death or serious injury.
NOTICE
IMPROPER INSTALLATION
• Maximum distance between SM1 & SM2 actuation points is A (mm) = V (mm/sec) x 3 (sec) where V is the conveyor speed.
• The muting sequence ends upon first end muting sensor de-activation (EM1).
• Distance (B) between SM2 and the FF-SYB and distance (C) between EM1 and the FF-SYB shall be lower than the object size
(L) if the Temporary Manual Muting is needed.
3.9.6 MUTING THE SAFETY LIGHT CURTAIN DURING THE UPSTROKE OF A MECHANICAL POWER
PRESS CYCLE
3
In this example, two limit switches SM1 & SM2 are used to start and stop a muting sequence (on a different machine, the sensors
could also be photoelectric controls, ultrasonic sensors or inductive proximity sensors). Correct operation of these sensors is
monitored by the FF-SYB.
As soon as the press tool reaches the Bottom Dead Center (BDC), the SM sensors are activated by the rotation of the rotating disk
cam and start the muting sequence. The limit switches keep their position till the press tool reaches the Top Dead Center (TDC).
The rotation of the rotating disk cam releases both limit switches and interrupt the muting sequence.
! DANGER
MECHANICAL POWER PRESS OPERATING IN REVERSE MODE
• The Honeywell muting function shall only be used during non-hazardous portion of the mechanical power press cycle, i.e.
during die opening when the press is running forward (crankshaft is running clockwise).
• If it is foreseeable that the press may be run in reverse or the press crankshaft rotation direction changed, even accidentally, do
NOT install the Honeywell muting system on the press.
• The muting function provided by the Honeywell product DOES NOT recognize the crankshaft rotation direction (clockwise or
counterclockwise). If muting is installed to operate during the upstroke when running forward (clockwise), then muting should
not occur during the downstroke when running reverse (counterclockwise). Muting is ONLY permitted during the upstroke (die
opening portion of the cycle).

! WARNING
INCORRECT INSTALLATION
• The position of the second sensor SM2 cam must be adjusted so that the SM2 sensor is activated when the press tool reaches
the Bottom Dead Center (or when the press tool reaches a position at 6 mm / 1/4 in above the Bottom Dead Center). At this
position, the operator is no more exposed to a dangerous situation, and the starting of the muting sequence avoids damaging
the part if the detection field of the light curtain is unexpectedly interrupted.
• Do NOT mute the light curtain during the closing stroke of the press.
Failure to comply with these instructions could result in death or serious injury.
NOTICE
IMPROPER INSTALLATION
The muting sequence ends upon first muting sensor de-activation (SM1).
3.9.7 MUTING THE SAFETY LIGHT CURTAIN DURING THE UPSTROKE OF A HYDRAULIC PRESS
CYCLE
In this example, a pair of limit switches SM1 & SM2 is used to start the muting sequence, and another pair of limit switches EM1 &
EM2 is used to stop the muting sequence (on a different machine, the sensors could also be photoelectric controls, ultrasonic
sensors or inductive proximity sensors). Correct operation of these sensors is monitored by the FF-SYB.

! WARNING
INCORRECT INSTALLATION
• The position of the second sensor SM2 cam must be adjusted so that the SM2 sensor is activated when the press tool reaches
the Bottom Dead Center (or when the press tool reaches a position at 6 mm / 1/4 in above the Bottom Dead Center). At this
position, the operator is no more exposed to a dangerous situation, and the starting of the muting sequence avoids damaging
the part if the detection field of the light curtain is unexpectedly interrupted.
• Do NOT mute the light curtain during the closing stroke of the press.
Failure to comply with these instructions could result in death or serious injury.
NOTICE
INCORRECT INSTALLATION
• SM1 & SM2 sensors should detect the presence of the tool when it reaches the Bottom Dead Center of the press to start a
muting sequence. The second sensor SM2 effectively starts the muting sequence.
• EM1 and EM2 sensors should detect the tool when it reaches the Top Dead Center (TDC) of the press. The second sensor EM2
effectively stops the muting sequence upon de-activation. If the second sensor EM2 is not activated when the tool reaches the
Top Dead Center, the next muting sequence is not allowed, and the intrusion of an object inside the safety light curtain
detection field stops the press.
