Notes for parameter settings
– The module independently performs a plausibility test for
the relevant pair of inputs or outputs, if the dual channel
mode is parameterised. On this it will be checked if both
inputs or outputs become active or inactive simultane-
ously within the discrepancy time.
– The “test pulse” parameter of an input must be disabled
(V1 variant) or set “external” (V2 variant) 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 UR20-4DI-4DO-PN-FSPS-V2 mod-
ule:
– 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.
ATTENTION
Please regard the following to ensure that the safety func-
tion will not be influenced.
– In the event that the output test pulses of a
UR20-4DI-4DO-PN-FSOE-V2 module are disabled output
errors will only be detected under the following condi-
tions:
– No filament lamp load must be connected.
– The capacitive load at this output may be 250 µF at
maximum.
