This manual contains description, operation, installation, electrical connections, maintenance and troubleshooting information related to the FF-SYB product. These installation instructions do not provide instructions for operating the machine on which the FF-SYB product is installed. Information about the machine operation can be found in the machine manufacturer s operating instructions. 1.2 ORGANISATION OF INSTALLATION MANUAL This installation manual has the following sections: 1 Important Information contains important highlighted information, the manual s organisation, control reliability information, approvals, standards, regulations and directives. Description and Operation provides operation and specification information. Installation explains how to properly install safety light curtains or the multibeam system for access detection. Connections and Setup covers electrical installation, interfacing and set-up procedures. Inspection and Maintenance contains inspection, maintenance, and indicator status information. Order Guides provide catalog listings of light curtains or multibeam systems, accessories, and spare parts. Warranty Information provides important contact information related to sales and service. Index contains keywords and their associated pages related to topics found throughout this manual. 1. 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. 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. 107120-20-EN FR26 GLO 804 Printed in France 5

2. 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-SYB0 and FF-SYB50 safety light curtains as well as for the FF-SYB24 safety multibeam systems for access detection. 2.2 MACHINE GUARDING AND PERIMETER PROTECTION The FF-SYB14 and FF-SYB0 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-SYB24 Series multibeam systems are used for access detection in dangerous areas where a body needs to be detected. 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. 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. 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. 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. 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.! 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. Figure 2-1 Perimeter Guarding (use the FF-SYB24 multibeam systems with deflection mirrors) 2 FSYB 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. 107120-20-EN FR26 GLO 804 Printed in France 9

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. Figure 2-4 FF-SYB Series Operational Diagram Sensing range Protection height FSYB4 2 Synchronisation beam Emitter 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-SYB0 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-SYB0 a resolution of 0 mm (1.2 in) and the FF-SYB50 a resolution of 50 mm (1.97 in). RESOLUTION AND FLOATING BLANKING Resolution is affected by the floating blanking. Refer to chapter "Floating blanking" to determine proper resolution.

2.4. 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: 2 Resolution without Resolution with 1 beam Resolution with 2 beam floating/blanking floating/ blanking floating/blanking FF-SYB14 14 mm / 0.55 in 24 mm / 0.94 in 4 mm / 1. in FF-SYB0 0 mm / 1.18 in 50 mm / 1.97 in 70 mm / 2.75 in FF-SYB50 50 mm / 1.97 in 90 mm /.54 in 10 mm / 5.12 in NOTICE The floating blanking IS NOT available with the 2-beam and -beam FF-SYB24 systems. Select the 4-beam FF-SYB24 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". 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. 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. Figure 2-6 Coil stock unwinding using floating blanking FSYB6 2.4.4 PROTECTION HEIGHT (FF-SYB14, FF-SYB0 AND FF-SYB50 SERIES) The protection height is the height on which the test rod will be detected (see chapter.7.1). 12 107120-20-EN FR26 GLO 804 Printed in France
2.4.5 BEAM SPACING AND NUMBER OF BEAMS (FF-SYB24 SERIES) For FF-SYB24 multibeam systems for access detection, beam spacing indicates the distance between the optical axis of two consecutive beams. The beam spacing of the FF-SYB multibeam system and the beam heights above the reference plane are in compliance with the European standards EN 999. Model Number of beams Beam spacing Beam heights above the reference plane (per EN 999) mm mm In FF-SYB02500 (-L) 2 500 400 / 900 15.8 / 5.5 FF-SYB0400 (-L) 400 00 / 700 / 1100 11.8 / 27.6 / 4. FF-SYB0400 (-L) 4 00 00 / 600 / 900 / 1200 11.8 / 2.6 / 5.5 / 47. 2 NOTICE NON COMPLIANCE TO ANSI/RIA 15.06-1999 WITH FF-SYB02500 Only the three beam FF-SYB0400 (-L) and the four beam versions FF-SYB0400 (-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-SYB24 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 scanning range logic of the test input (see chapter "Test input") is visible through the transparent front window of the emitter without removing the end cap.

MINIMUM SCANNING RANGE (FF-SYB14, FF-SYB0 and FF-SYB50 only) Using the FF-SYB14, FF-SYB0 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. 2 IMPROPER MINIMUM SCANNING RANGE (FF-SYB24 only) Always install the FF-SYB24 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-SYB24 multibeam systems for access detection may NOT comply with IEC/EN 61496-2 optical requirements for aperture angle. 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 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. 2 TESTS AND CONTROLS Always perform tests and controls listed in the "wiring diagram and installation controls" after any installation modification. 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.

How to program operation modes If you need a different configuration card than card # 01 ( "M O NB P" code, factory setting) for the receiver, or card #102 ("50% NO" code, factory setting) for the emitter, follow the following steps to change configuration cards: Ensure the following tools are available: A cross point screwdriver (Pz #1) A flat-head screwdriver (2 mm / 1/10 in width). 1.Remove the bottom end cap (use a cross point screwdriver to unscrew cover). 2.Hook up the card hole with a flat head screw driver (the hole is located on the right hand side, at the bottom of the card), pull out the configuration card in place. 1 & 4 2. Select the configuration card needed for the application (See above configuration card selection guide), and insert it into the slot with inscriptions upward. 2 4.Screw the end cap tight. 5. When the whole installation is completed, perform the tests & controls listed in the "Wiring diagram and installation controls" chapter. IF THE RECEIVER UNIT NEEDS TO BE CHANGED Check the card code through the clear window located at the bottom of the unit installed on the machine first, then program the new unit following the above mentioned procedure. Always perform tests & controls listed in the "wiring diagram and installation controls", after any installation modification. 2.5 INDICATORS The FF-SYB Series emitters have five LED indicators. The receivers have eight LED indicators. These LED indicators provide important information related to the light curtain status. Figure 2-11 Emitter Indicators R2 R alarm test R1 Scanning range indicators (yellow) Alarm indicator (red) Test indicator (red) 50% NO FSYB17 2.5.1 SCANNING RANGE INDICATORS (EMITTER) R R2 R1 R R2 R1 yellow yellow yellow FSYB18 yellow yellow yellow FSYB19 R R2 R1 yellow yellow yellow FSYB20 Maximum scanning range Medium scanning range (factory setting) Minimum scanning range The emitter is equipped with a scanning range selector for the control of the infrared emission power. The scanning range indicators are yellow indicators which give an information on the selected scanning range. If R1, R2 and R are all OFF, the configuration card is missing. See chapter "Scanning Ranges" for further information. 2.5.2 ALARM INDICATOR (EMITTER) Alarm Red Normal operation FSYB21 Emitter failure Red The alarm indicator is a red LED that flashes if the emitter is detecting an emission problem. The receiver is in an alarm state and the emitter needs to be changed for correct operation. If this LED is off while the receiver is in an alarm state despite the sensing field is clear, then the receiver may be suspected. If the alarm indicator is permanently ON, the configuration card is missing. 107120-20-EN FR26 GLO 804 Printed in France 19 Alarm FSYB22
2.5. TEST INDICATOR (EMITTER) 2 Test Red Normal operation FSYB21 Test Red Test mode The test contact allows verification of external safety-related electromechanical components before each machine cycle. When the contact in the external test circuit is actuated, the FF-SYB Series light curtain safety outputs switch off. The red test indicator of the FF-SYB emitter turns on and the static (solid state) safety outputs of the FF-SYB receiver remain open while the test contact is actuated. The customer is responsible for providing the external test circuitry (See chapter "Electrical Connections"). FSYB2 Figure 2-10 Receiver Indicators OFF ON restart muting No blanking 1 blanking 2 blanking MM20MBP FSYB24 2.5.4 OPERATION INDICATORS (RECEIVER) OFF ON FSYB25 OFF ON FSYB26 Red Green Red Green Outputs are closed Outputs are open The operation indicators are two green and red LED indicators that provide output 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 outputs are off. If the sensing field is interrupted, the FF-SYB Series light curtain will immediately generate a stop signal. In this condition, the green LED will be off. 2.5.5 SIGNAL STRENGTH INDICATOR (RECEIVER) FSYB27 FSYB28 FSYB29 Orange Optimum signal Orange Low signal Orange No signal The signal strength indicator is an orange 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, the light curtain outputs switch off and generate 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. 20 107120-20-EN FR26 GLO 804 Printed in France
2.5.6 CROSS-TALK INDICATOR (RECEIVER) No cross- talk FSYB0 Cross-talk detection FSYB1 Red Red 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 "Mutual Interference or cross-talk"). 2.5.7 RESTART INDICATOR (RECEIVER) 2 Restart Restart Yellow Manual restart expected Yellow Wiring error or auxiliary safety device engaged The restart indicator is a yellow LED which flickers when the FF-SYB is expecting a restart command after an interruption of the protection field as soon as the protection field is made free again. It will be ON if the Auxiliary Safety Device is engaged or in case of incorrect wiring. 2.5.8 MUTING DIAGNOSIS INDICATOR Muting/diagnosis Muting/diagnosis Muting/diagnosis Orange No muting Orange Problem in muting sequence or wiring error Orange Muting in progress The muting indicator is an orange indicator which is ON when a valid muting sequence is in progress (meaning that the muting sensors have been actuated with the correct sequence). It is OFF when the FF-SYB operates in normal (or guard) mode. It will flicker if a wrong muting sequence is detected. When the muting/diagnosis LED flickers while the restart LED is ON, the FF-SYB has detected an incorrect wiring on its inputs. 2.5.9 FLOATING BLANKING INDICATORS Blanking off Floating blanking 1 beam Floating blanking 2 beams The floating blanking indicators are 2 yellow LED which are ON when operation without floating blanking is selected (default configuration). The left indicator is ON and the right indicator is OFF when 1 beam floating blanking is selected. The right indicator is OFF and the left indicator is ON when 2 beams floating blanking is selected. 2.5.10 EXTERNAL INDICATOR The FF-SYB provides one additional output which function can either be a normally closed signalling contact or a muting lamp/ diagnosis output, depending on the light curtain set up. When an indicator is connected to this output, it displays the same information as the muting/diagnosis embedded indicator. STATUS OUTPUT NOT SUITABLE FOR SAFETY USE DO NOT use the status output for personnel protection. It cannot be used to stop the machinery. Use the safety outputs for personnel protection. 107120-20-EN FR26 GLO 804 Printed in France 21
