Integral system diagnosis (ISD)

Note (ISD -Faults)	The following faults are registered by the safety monitoring modules and indicated by ISD.
Faults	Failure of the safety relay to pull-in or drop-out Fault on the input circuits or the relay control circuits of the safety monitoring module Failure of the proximity switches Failure of one channel being evaluated Interruption of the connections to the inductive proximity switches

Other data

Note (applications)	safe standstill monitoring

Notes

Note (General)	Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit.

Circuit example

Note (Wiring diagram)	The wiring diagram is shown with guard doors closed and in de-energised condition. The ISD tables (Intergral System Diagnostics) for analysis of the fault indications and their causes are shown in the appendix. To monitor one guard door at plants with dangerous run-on movements up to PL d and Category 3 Standstill monitoring for unlocking solenoid interlocks The solenoid interlock can be opened, when the fail-safe standstill monitor has detected the end of the run-on movement by means of two inductive proximity switches. When the button (E) is actuated, the coil of the solenoid interlock is energised. For suitable IFL range p-type inductive proximity switches, refer to 'Schmersal Catalogue Automatisierungstechnik'.
