4.3.2 Diagnoses in the cut-off circuit
The cut-off circuit is equipped with durably implemented and parametrizable diagnostics
functions. Certain diagnostics functions also include the external part of the cut-off channel.
Depending on he use of these diagnostics functions, different DC-values will arise.
4.3.2.1 Diagnostic Functions
Durably implemented diagnostics functions:
Cross-wire readback of outputs:
All safety outputs are read back in the complementary channel. Faults in the internal cutout circuit
of the PSCBR module are thus detected with DC = High.
Test of cutout ability for Rel 1 and 2 (only control of relay), DO 0P, DO 0M,
DO 1P, Do 1M:
The cutout ability of these outputs is cyclically tested. Failure of the cutout possibility is clearly
detected.
Parametrizable diagnostics functions:
Readback of the actuator status via auxiliary contacts, position indicators, etc.:
