The rotation speed monitor RC3 500 Hz controls the three speed ranges of the underspeed, nominal speed and overspeed as well as the state of the direction reversal. The hazardous conditions of underspeed, change of direction, overspeed and sensor failure lead to the motor being switched off. Inductive proximity switches can be adapted as pulse pick-ups. The sensor is supplied by the device and does not require an external power supply. A floating relay contact is required for connection to the staircase control.
Special features include:
The rotation speed monitor RC3 500 Hz is used in escalators.
