Integral system diagnosis $missingShortName$
 
Integral system diagnosis ISD
- The following faults are registered by the safety monitoring modules and indicated by ISD
- Interruption of the connections to the inductive proximity switches
- 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

notice
 
Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit.
 
notice - Wiring example
 
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".
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.
