4.5. Connecting indicator lamps to auxiliary terminals
POWER APPLIED TO MACHINE CONTROL SYSTEM
Before intervention, turn off and disconnect power from FF-LS Series safety light curtain and machine.
Failure to comply with these instructions could result in death or serious injury.
Per the EN 61496 (previously pr EN 50100 - part 1) standard, the control unit allows installation of lamp indicators as follows:
A green lamp indicator must be connected between the ON terminal and ground. The COM terminal should be connected
to the +24 volt power supply. The ON and COM terminals are located on the control unit circuit board. When the lamp
illuminates (ON), no beams are interrupted, no failures are detected and the output NO contacts are closed.
A red lamp must be connected between the OFF terminal and ground. The COM terminal should be connected to the +24
volt power supply. The OFF and COM terminals are located on the control unit circuit board. When the lamp illuminates
(ON), at least one beam is interrupted, or a failure is detected and the output NO contacts are opened.
Both lamps operate complementarily.
4.6. Connecting the test input
POWER APPLIED TO MACHINE CONTROL SYSTEM
Before intervention, turn off and disconnect power from FF-LS Series safety light curtain and machine.
Failure to comply with these instructions could result in death or serious injury.
The test input provides a way to test the functionality of the entire machine safety system. The connection of the test input to an
external 24 Vac/dc supply turns off (opens the NO contacts of the FF-LS safety light curtain) the equipment even if the beams have
not been broken. Once connection between the test input and the external 24 Vac/dc supply is established, ensure that every
component of the machine safety control circuitry is operating correctly.
Notes:
1) External 24 Vac/dc supply: 24 Vac/dc, ±25 % (48 to 62 Hz). Photocouplers provide an electrical isolation from the rest of
the system. Minimum closing time is 100 ms.
4.7. Setting the mode of operation
POWER APPLIED TO MACHINE CONTROL SYSTEM
Before intervention, turn off and disconnect power from FF-LS Series safety light curtain and machine.
Failure to comply with these instructions could result in death or serious injury.
IMPROPER MACHINE RESTART
Clearing the sensing zone must not start dangerous machine operation. When restarting the machine operation, a normal
machine control sequence must be used.
If electrical power is removed from a machine, its restoration must not initiate dangerous machine operation; a normal
machine control sequence must be used.
If a safety light curtain is activated, the machine must NOT be able to restart.
A Programmable Logic Controller must NOT be able to override a manual restart function.
Failure to comply with these instructions could result in death or serious injury.
The FF-LS Series safety light curtain may operate in one of two following modes:
In the Automatic mode, the FF-LS starts automatically at power up and restarts automatically after any intrusion in the
sensing field.
In the Start and Restart Interlock (manual) mode, pushing an external push button (customer supplied) is necessary to
restart the equipment at power up and after any intrusion into the sensing field.
To select the proper mode of operation do the following:
Remove the protective plastic covers located on each side of the control unit face plate lid using a small screwdriver (small
recess in covers).
Loosen four captive screws securing the face plate lid on the control unit housing and remove the lid.
