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
Miscellaneous data
Applications safe standstill monitoring
- Width45 mm
- Height100 mm
- Depth121 mm
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.
If only one inductive proximity switch is connected to the standstill monitor, the standstill frequencies must be identical and inputs X2 and X4 must be bridged.
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.
