1.3 Important Highlighted Information
Important danger, warning, caution and notices are highlighted throughout the manual as follows:
A DANGER symbol indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.
A WARNING symbol indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
A CAUTION symbol indicates a potentially hazardous situation which, if not avoided, may result in property damage.
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-SYA 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/ pr 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.

2. Description and Operation
2.1 Overview
This chapter contains terms and concepts related to safety and the application of the FF-SYA 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.
In order to simplify this manual, the term “safety light curtain”is used for the FF-SYA14, FF-SYA30 and FF-SYA60 safety light
curtains as well as for the FF-SYA234 safety multibeam systems for access detection.
2.2 Machine Guarding and Perimeter Protection
The FF-SYA14 and FF-SYA30 Series through-scan light curtains are non-contact machine guarding devices designed for
point-of-operation protection at power driven machinery (see Figure 2-1) where fingers or hands need to be detected.
The FF-SYA60 Series light curtains are designed for presence detection in dangerous areas where legs or a body need to be
detected.
The FF-SYA234 Series multibeam systems are used for access detection in dangerous areas where a body needs to be
detected.
IMPROPER INSTALLATION OF FF-SYA SERIES LIGHT CURTAIN
•Install FF-SYA 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-SYA 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-SYA Series light curtain monitors itself continuously for component failures, misalignments,
and dirt accumulations. 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.
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-SYA Series light curtain.
•Ensure two independent stop circuit relays have mechanically linked contacts to reliably detect a welded contact.
•Using the FF-SRS59392 safety control module 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-SYA 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.
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.

Figure 2-1 Point-of-operation Guarding (use FF-SYA14 and FF-SYA30 only)
Point-of-operation is defined as that area where a machine performs work (such as cutting, shaping, boring, or forming) on a
material.
FULL REVOLUTION MECHANICAL POWER PRESSES CANNOT BE STOPPED IN MID-STROKE (OSHA 29CFR
1910.217). DO NOT use FF-SYA Series light curtains on full revolution mechanical power presses.
Failure to comply with these instructions will result in death or serious injury.
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.
Figure 2-2 Point-of-operation Guarding (use the FF-SYA14 and FF-SYA30 light curtains only)
IMPROPER POINT-OF-OPERATION PROTECTION
Do NOT use FF-SYA60 Series light curtains or the FF-SYA234 multibeam systems in point-of-operation applications.
Failure to comply with these instructions will result in death or serious injury.

cCSAus The Canadian Standard Association has been accredited as a Nationally Recognised Testing Laboratory (NRTL)
by the US Occupational Safety and Health Administration (OSHA). The CSA is able to carry out tests according to
the Canadian and UL standards and delivers a single certificate which is valid for both Canada and the United
States.
2.4 Operation
The FF-SYA 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.

Sensing range
Protection Height
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-SYA14, FF-SYA30 and FF-SYA60 Series)
FF-SYA 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. For safety reasons,
the FF-SYA Series does not have a sensitivity adjustment. Two factors determine the resolution of the light curtain: beam pitch
and light lens diameter (see Figure 2-8).
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-SYA14 (see Figure 2-7) a resolution of 14 mm (0.6 in), the FF-SYA30 a resolution of 30 mm (1.2 in) and
the FF-SYA60 a resolution of 60 mm (2.4 in).

MINIMUM SCANNING RANGE (FF-SYA14, FF-SYA30 and FF-SYA60 only)
Using the FF-SYA14, FF-SYA30 or FF-SYA60 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.
IMPROPER MINIMUM SCANNING RANGE (FF-SYA234 only)
Always install the FF-SYA234 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-SYA234 multibeam systems for access detection may NOT comply with IEC/ pr EN 61496-2 optical requirements for
aperture angle.
Failure to comply with these instructions could result in death or serious injury.

FF-SYA Series light curtains provide a connection for testing the state of external contacts in case of long machine working
cycle. The test contact allows verification of external safety-related electromechanical components before each machine cycle.
When the contact in the external test circuit opens, the FF-SYA Series light curtains switches to the alarm state. The red tes
t
indicator turns on and the fail safe static outputs remain open while the test circuit is open.
The customer is responsible for providing the external test circuitry (See Electrical Connections).

The operation indicators are two green and red LED indicators that provide operation status. The green LED indicates the
receiver operates normally and the sensing field is clear. This indicator must be on to ensure the equipment is working properly
(the red LED will be off). The red LED indicates that the light curtain is in an alarm state. If the sensing field is interrupted, the
FF-SYA Series light curtain will immediately generate a stop signal. In this condition, the green LED will be off.

The signal strength indicator is a yellow indicator which flashes repeatedly if the received light level is lower than the normal
operating level, but is still sufficient for operation. If the received light level drops too low, an alarm state results and the light
curtain generates a stop signal. To prevent unnecessary shutdowns, this indicator will signal the need for cleaning and/or
alignment. This indicator also provides useful indication for beam alignment during the installation step.

The cross-talk indicator is a red LED which lit on if the receiver receives two different signals from two different emitters. In this
case, the light curtain is maintained in a lock-out condition. This LED helps identify cross-talk between light curtains. For correct
operation this LED shall be off. To go back to normal operation, switch the power off and eliminate the interferences by reversing
systems emitting orientation, or by using opaque screens, or by adjusting the adequate emission power regarding the application
(see chapter 3.6. Mutual Interference or cross-talk).

3. 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.
FULL REVOLUTION MECHANICAL POWER PRESSES CANNOT BE STOPPED IN MID-STROKE (OSHA 29CFR 1910.217).
•DO NOT use FF-SYA Series light curtains on full revolution mechanical power presses.
Failure to comply with these instructions will result in death or serious injury.
IMPROPER INSTALLATION OF FF-SYA SERIES LIGHT CURTAIN
•Install FF-SYA 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.
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 safety operation
•Ensure two independent stop circuit safety relays have mechanically linked contacts to reliably detect a welded contact.
•Using the FF-SRS59392 safety relay module will provide static safety contacts to the machine control stop circuit.
Failure to comply with these instructions could result in death or serious injury.
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
IMPROPER POINT-OF-OPERATION INSTALLATION.
•Do NOT use the FF-SYA234 multibeam systems or the FF-SYA60 light curtains for point-of-operation guarding. Use the
FF-SYA14 or FF-SYA30 light curtains only.
•DO NOT allow an operator to stand undetected between the light curtain and the machine when using FF-SYA 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-SYA14 and FF-SYA30 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, safety mats or safety scanners may be required.
3.3 Perimeter Guarding
IMPROPER INSTALLATION OF FF-SYA SERIES PERIMETER DEVICE
•Install the FF-SYA234 multibeam systems or the FF-SYA60 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.

107031-33-EN FR26 GLO 1101 Printed in France 15
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.
Honeywell's FF-SYA234 multibeam systems and the FF-SYA60 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
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
•t1is the response time of the FF-SYA light curtain.
•t2is 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
