Wiring example
| Note (Wiring diagram) | The wiring diagram is shown with guard doors closed and in de-energised condition. The sensor-free standstill monitor checks the e.m.f. of the three phase motor. The SRB range guard door monitor checks the position of the guard door. Monitoring the guard door using a solenoid interlock and a safety switch with separate actuator (A and B). Release takes place by means of the NO contact (E) only when the run-down movement has been terminated. After release has taken place, the guard door must be opened. To secure a guard door |
