notice - Wiring example
 
To secure a guard door up to PL 3 and Category #03#
Monitoring a guard door using zwei position switches with safety function.
The NC contact A must have positive break when the guard door is opened.
Category 3 to EN 954-1 can also be achieved using only one safety switch with one NO and one NC contact. Exclusion of faults due to breakage or loosening of the actuating element or the actuating head as well as releasing, dismantling.
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.
If neither start button nor feedback circuit are connected, a jumper connection must be mounted between X1 and X2.
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.
