External test function
Some category 4 applications require that the machine guarding system is
tested by the machine controller during a non-hazardous portion of the
machine cycle to verify that the guarding system is functioning properly. In
category 2 the test should be done by machine operator. F3S-TGR-CL sys-
tem offers a test function on the transmitter or on the receiver element.
Transmitter:
The test function is provided by placing a normally-open switch on the test
input of the transmitter. If the transmitter recognizes a +24VDC signal, a beam
block state will be simulated on the transmitter and the receiver will enter the
MACHINE STOP state.
Wiring diagram:
Receiver:
The test function is provided by placing a switch on the test/restart input of the
receiver.
If the outputs are in OFF state, the system will run a start-up-test and if the
beams are free, it will change to MACHINE RUN state.
If the outputs are in ON state and the test/restart input is activated for more
than 2sec., the system will enter MACHINE STOP state and run a start-up-
test (for Category 2 control systems).
