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.
