Integral system diagnosis $missingShortName$
 
Integral system diagnosis ISD
- The following faults are registered by the safety monitoring modules and indicated by ISD
- Failure of door contacts to open or close
- Cross-wire or short-circuit monitoring of the switch connections
- Interruption of the switch connections
- 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

notice
 
Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit.
 
notice - Wiring example
 
To secure one or a number of guard doors up to PL d and Category 3
Monitoring a number of guard doors using magnetic safety sensors BNS range
The NC contact must have positive break when the guard door is opened.
If one or two external relays or contactors are used to switch the load, the system can then only be classified in Category 3 to EN ISO 13849-1, if exclusion of the fault “Failure of the external contactors” can be substantiated and is documented, e.g. by using reliable down-rated contactors. A second contactor leads to an increase in the level of security by redundant switching to switch the load off.
Expansion of enable delay time:
The enable delay time can be increased from 0,1 s to 1 s by changing the position of a jumper link connection under the cover of the unit.
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.
