AZR31T0/24VDC/AC
- Fail-safe standstill monitors
- Sensor-free detection of standstill by monitoring e.m.f.
- Direct connection to three-phase motors
- Suitable for connection to a frequency converter with the following interface date: rotary hysteresis 0 ... 1000 Hz; switching frequency of the end level up to 16 kHz; engine voltage range 0 ... 400 V
- This fail-safe standstill monitor has the particular advantage that no adjustment for a required-value is needed during comissioning.
- 3 safety contacts, STOP 0
- 1 Signalling output

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 |
