STEP MOTOR VARIMAX
The rotor is powered by a step motor with automatic restart and alarm reset in the
event of power failure. The unit has an integrated blow-off function as standard.
When the rotor is stationary, a holding torque is activated, which ensures that the
rotor actually remains stationary.
The control unit is equipped with a rotation monitor that emits an alarm if e.g. the
belt becomes dislodged. A built-in input signal offset provides an efficiency proportio-
nal to the input signal.
Two LED lights indicate operation.
The alarm is triggered for the following reasons:
•
Rotation monitor
• Motor temperature
• Overvoltage
• Undervoltage
• Over/under temperature, control unit
• Short circuit
• Internal fault

Operation Illuminates when the motor will rotate, i.e. when the input signal exceeds
the threshold value
Rotation Flashes every time the magnet passes the magnet sensor, regardless the
setting of the DIP switch “Rotation monitor”.
Also flashes if the input signal is lower than the threshold value.
