• 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

- noticeThe PFH value is applicable for the combinations listed in the table for contact load (K) (current through enabling paths) and switching cycle number (n-op/y).
In case of 365 operating days per year and a 24-hour operation, this results in the specified switching cycle times (t-cycle) for the relay contacts.
Diverging applications on request.

notice - Wiring example
 
The sensor-free standstill monitor checks the e.m.f. of the three phase motor.
To secure a guard door
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.
The wiring diagram is shown with guard doors closed and in de-energised condition.
