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
- Fault on the input circuits or the relay control circuits of the safety monitoring module

- Width75 mm
- Height100 mm
- Depth110 mm
Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit.
notice - Wiring example
To secure 4 guard doors up to PL d and Category 3
Monitoring 4 guard door(s), each with a magnetic safety sensor of the BNS range
The feedback circuit monitors the positions of the positive-guided NC contacts on the conactors K3 and K4.
Start push button A start push button (NO) can optionally be connected into the feedback circuit. With the guard door closed, the enabling paths are then not closed until the start push button has been operated.
The NC contacts of the external contactors must be wired in series to X1 (+) and X2.
If less than 4 switches are connected, those S21/S22 terminals which are not used for connection of an NC contact must be fitted with a shorting connection. This is based on the applicable jumper inside the safety monitoring unit being set for the NC-NO configuration.
The switch (H6) connected to terminals X3 and X4 switches the enabling outputs Y14 and Y24 on and off with the guard door closed. If no switch is connected, a jumper connection must be mounted between the terminals X3 and X4.
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.
