1) Please regard the notes for parameter settings.
Notes for parameter settings
– The module independently performs a plausibility test for
the relevant pair of inputs, if the dual channel mode is
parameterised. On this it will be checked if both inputs
become active or inactive simultaneously within the dis-
crepancy time.
– The “test pulse” parameter of an input must be disabled
(variant V1) or set “external” (variant V2) if a safety device
with OSSD outputs generating own test pulses is con-
nected.The test pulse duration depends on the parame-
terised input delay:
Input delay [ms] 1 3 10 100
Test pulse duration [ms] 0.5 1 3 10
– Please regard the following when parameterising „exter-
nal“ test pulses with a UR20-8DI-PN-FSOE-V2 module:
– An edge transition must occur at least every five min-
utes at an active input. Otherwise a module error will
be signalised.
– With this setting the module cannot detect any short
circuits. The short circuit detection must be realised by
the connected OSSD device.
