Integral system diagnosis (ISD)

Note (ISD -Faults) : The following faults are registered by the safety monitoring modules and indicated by ISD.

Faults :

Failure of the safety relay to pull-in or drop-out

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

Other data

Note (applications) : Safety sensor, Guard system

Note

Note (General) :

Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit.

Wiring example

Note (Wiring diagram)

The wiring diagram is shown with guard doors closed and in de-energised condition.

To secure a guard door up to PL d and Category 3

Monitoring 1 guard door(s), each with a magnetic safety sensor of the BNS range

The ISD tables (Intergral System Diagnostics) for analysis of the fault indications and their causes are shown in the appendix.
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 feedback circuit monitors the position of the contactors 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.

If only one external relay or contactor is used to switch the load, the system can be classified in Control Category 3 to ISO 13849-1, if exclusion of the fault “Failure of the external contactor” can be substantiated and is documented, e.g. by using a reliable down-rated contactor. A second contactor leads to an increase in the level of security by redundant switching to switch the load off.

If neither start button nor feedback circuit are connected, a jumper connection must be mounted between X1 and A1.

Modification for 2 NC contacts: The safety monitoring module can be modified to monitor two NC contacts by bridging the terminals A1 and X2. In this configuration, the short-circuit detection becomes inoperative.
