notice | |
| Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit. | |
notice - Wiring example | |
| To secure a guard door up to PL 4 and Category #03# | |
| Monitoring 1 guard door(s), each with a magnetic safety sensor of the BNS range | |
| The feedback circuit monitors the position of the contactors Ka and Kb. | |
| 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) | |
| The wiring diagram is shown with guard doors closed and in de-energised condition. | |
