Wiring example
| Note (Wiring diagram) |
The wiring diagram is shown with guard doors closed and in de-energised condition. 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). 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. The control recognises cross-short, cable break and earth leakages in the monitoring circuit. Switch setting: The cross-wire short detection function (factory default) is programmed by means of the switch located underneath the front cover of the module: Pposition nQS (top): no cross-wire short protection, suitable for 1-channel applications and applications with outputs with potential in the control circuits. Position QS (bottom): cross-wire short protection, suitable for 2-channel applications without outputs with potential in the control circuits. For 1-channel control, connect NC contact to S11/S12 and bridge S12/S22 (QS-switch = nQS) Connect potential p-type outputs of safety light grids/curtains to S12/S22. The devices must have the same reference potential. QS-switch = nQS Automatic start: The automatic start is programmed by connecting the feedback circuit to the terminals S12/X3. If the feedback circuit is not required, establish a bridge. F1 = Hybrid fuse |
