Integral system diagnosis $missingShortName$
 
Integral system diagnosis ISD
- The following faults are registered by the safety monitoring modules and indicated by ISD
- 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
- Difference in time setting between channel I and channel II
- Cross conclusions to the input lines
- Interruption of the input connections

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
Monitoring time for unlocking of solenoid interlocks
The solenoid interlock releases the guard device only when the set time has elapsed.
The time begins to run when the power contactors have dropped out.
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.
