ATTENTION
To ensure the safety functions regard the following instruc-
tions for adjustment:
– DIP switches of equal numbers must have identical posi-
tions in both rows.
– If an external device generating pulses is connected to a
safety input of the UR20-PF-O-2DI-DELAY-SIL, this input
must be operated in mode “no test pulses” (DIP switch
setting “ON”).
– When operating in mode “no test pulses”:
– The test pulses of the external device must be shorter
than 2ms, otherwise the safe output will be deacti-
vated.
– A safe laying of cables can be neccessary depending
on the required safety level.
▶ Please use e.g. a ball pen to set the DIP
switches and avoid spiky or sharp-edged tools.
