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. 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. To secure a guard door up to PL e and Category 4 The feedback circuit monitors the positions of the positive-guided NC contacts on the conactors Ka and Kb. |
