Check that

the control unit is connected as per instructions on page 10.
Connection voltage 230-240 V +/-15%, 50/60 Hz.

Check that

the motor is wired for 3 x 230 V. If there is an operating switch between 
the motor and the control unit, the motor thermal contact should be 
connected via the auxiliary terminal in the operating switch.

Check that

the input signal is 0-10 V

.

Check that

the cleaning function and rotation monitor DIP switch are set to ON.

PUTTING THE EQUIPMENT INTO OPERATION

 

Should be done in sequence. 

Check that

the motor rotates in the right direction in relation to the wheel's direction 
of rotation. In the event of a fault, switch two phases to the motor.

Adjustment of  
maximum rpm

Set the “High Speed” DIP switch to the ON position. 
Adjust "Max. rpm" so that the wheel rotates at 10-12 rpm  
(or as per directions from wheel manufacturer).
After a test run, set the DIP switch to OFF.

Checking 
minimum rpm

Set the “Low Speed” DIP switch to ON. 
Check that the wheel starts. 
The minimum rpm is preset. 
After a test run, set the DIP switch to OFF.

Checking the  
cleaning function

Switch off the voltage.
Make sure the “Cleaning function” DIP switch is set to ON and the input 
signal is disconnected. When power is switched on, the wheel will rotate 
at minimum rpm for 10 seconds.

Checking the  
rotation monitor

The yellow “Rotation” LED will flash when the magnet passes the 
magnetic sensor, regardless of DIP switch position.

Finish by

having the control unit drive the wheel at maximum and minimum  
rpm and checking that the wheel speed is correct.
