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.
