Note (A):
Connect test output terminal 58 to the test input of each FF-SGL18 / FF-SLG30 emitter as shown in the wiring diagram above while
respecting the polarity of the test input terminals (test input (+) = terminal 6, test input (-) = terminal 1).
Note (B):
Auxiliary safety device for robot position (use is application depending and may be optional):
When a safety switch (that typically does not have a test input) is used as robot position sensor, connect the test output terminal 58
as shown above, in order to ensure the switch being also tested.
When no robot position sensor is used, connect the unused terminals to power and to the test output: S31 to (dc-); S32 to 58.
