Integral system diagnosis ISD
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
Inductive loads ( e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit.
notice - Wiring example
To secure a guard door up to PL 3 and Category # 03#
Monitoring 1 guard door( s) , each with a magnetic safety sensor of the BNS range
Modification for 2 NC contacts:
The safety monitoring module can be modified to monitor two NC contacts by bridging the terminals X3 and X4. The short-circuit recognition between connections then becomes inoperative.
Inversion of the output function:
By establishing a bridge between X5 and X6, the output function of the additional outputs can be altered. This control can also be realised when e.g. a PLC is running ( 24 VDC at terminal X6) .
Expansion of the enable delay time
The enable delay time can be increased from 0, 1 s to 1 s by mounting a jumper connection between the terminals X7 and X8.
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.
