notice - Wiring example |
|
Input level: The example shows a 2-channel control of a guard door monitoring with two position switches, whereof one with positive break, external reset button (R) and feedback circuit (H2). |
The control recognises cross-short, cable break and earth leakages in the monitoring circuit. |
Relay outputs: Suitable for 2 channel control, for increase in capacity or number of contacts by means of contactors or relays with positive-guided contacts. |
Time delay: The time-delayed safety enable 37/38 is adjustable for 1 to 30 seconds drop-out delay (see setting intructions). |
The safety enabling circuit 37/38 conforms to EN 60204-1 for STOP Category 1. The safety enabling circuits 13/14 and 23/24 conform to EN 60204-1 for STOP Category 0. |
Setting of the drop-out delay time is carried out by means of a potentiometer from the front of the enclosure. |
The wiring diagram is shown with guard doors closed and in de-energised condition. |
