TEST INPUT
When a type 3 or type 4 safety device is not often actuated, it may be useful to test the connected emergency stop chain from
time to time. For this purpose, the FF-SRM200P2 muting module is equipped with a test output allowing to test the correct
functioning of the connected emergency stop chain (i.e. safety device incl. external contactors, safety control modules, etc.) at
certain steps of the process.
When connecting type 2 safety devices to the FF-SRM200P2 muting module, the test function must be used to check the safety
integrity of the safety device.
Safety devices compatible with the FF-SRM200P2 test output
•
FF-SLG18 and FF-SLG30 type 2 safety light curtains (all models with the exception of FF-SLG18147B2 and FF-SLG30147B2)
•
Safety switches (e.g. for safety door monitoring).
Modes with test (see table page 6)
•
Muting modes 50 to 79.
•
Mutual exclusion modes 92 and 93.
In these modes the output terminal 58 is used as test output and it must be connected to the test inputs of all connected safety
devices, that are tested simultaneously.
A test signal is generated
•
At each activation of the start push-button and each activation of the acknowledge push-button
•
At each new and valid muting sequence (muting lamp light on).
NOTICE
•
The FF-SLG18/30 emitter and receiver needs to be powered AFTER the FF-SRM200P2 muting module. Otherwise, the test
sequence at power up may not work.
•
The connected safety devices must respond within max. 200 ms after the generation of the test signal, otherwise the module
will display an error (see « Diagnostic Information »).

Note (A):
Connect test output terminal 58 to the test input of each FF-SLG18 / FF-SLG30 emitter as shown in the wiring diagram below while
respecting the polarity of the test input terminals (test input (+) = terminal 6, test input (-) = terminal 1).
Modes 50 to 59 (only): 1 non-mutable and 1 mutable safety device AND safety devices with test input: the mutable safety device
needs to be activated during the muting sequence.
