Probable fault cause 
during installation

Probable fault cause in 
operation

- Magnet turned the wrong way
- Magnet transmitter incorrectly connected (wrong polarity),  
  

    

refer to "connections" on page 9

- Gap too wide between the magnetic sensor and magnet; max 15 mm

- Broken belt
- Belt slipping
- Stuck rotor
- Magnetic sensor or magnet not intact

Motor temperature

Alarms and trips if motor winding temperature is too high. The 
temperature switch in the motor reverts to normal mode when the 
temperature  drops.

Excess voltage

Alarms and trips if the input voltage exceeds 265 V.

Under-voltage

Alarms and trips if the input voltage falls below 190 V.

Excessive /under-
temperature

Alarms and trips if the temperature in the control unit goes above/below 
safe temperature level (+85 - -30 

O

C).

Short circuit

Probable cause

Alarms and trips in the event of short circuit phase-phase or phase-earth.

- Short circuit between phases in cable or motor
- Short circuit between phase-earth in cable or motor
- Interruption to one phase in cable or motor

Measure motor resistance; it should be identical on all coils.

Internal fault

Alarms and trips if an internal fault in the control system has occurred.

SETTINGS VIA POTENTIOMETER

Manual speed

By closing A1-A2 the speed is controlled via the potentiometer marked 
"Manual speed". Can be regulated between 1 and 350 rpm. 
The rotor rotates at the set speed, whatever the value of the input signal.
Factory setting: 1 rpm on motor shaft.

Max speed

Potentiometer for adjusting max. speed.
Regulates between 50 and 400 rpm. 
Factory setting: 50 rpm on motor shaft.

PUSH BUTTON

Reset

Reset button for resetting the control unit. The control unit is also reset in 
the event of voltage drop-out and closure between terminals 11 and 12.
