Same test as before, but additional monitoring of the input signals for compliance with the
defined level connections within a time window of 0.5 seconds. Defining the levels over a time
period of > 0.5 seconds triggers a module alarm.
Start test:
Each time the safety module (=PSCBR module) is switched on, the input element must be
tested in direction of the Low signal status (defined Safe State), e.g. by actuating the
Emergency Stop button or a door lock after the system has been started.
Operational / organizational tests:
Apart from the previously mentioned diagnostic measures for the PSCBR modules, cyclic
testing can be performed within the application. These tests can also be used when assessing
the DC.
Note:
Operational/organizational tests can also be used for a combination of hardware inputs and
functional inputs (input information transferred via standard field bus). However, an exclusive
use of functional inputs is ruled out in this context (combination of two or more functional
inputs).
The PSCBR modules therefore ensure far reaching diagnostics functions for the partial input
system. These are performed permanently or optionally (cross-shorting monitoring by means
of pulse identifier).
