Check that

the control unit is connected as per instructions on page 9.
Power supply 230-240 V +/-15%, 50/60 Hz.

Check that

the input signal is 0-10 V.

Check that

the rotation monitor and cleaning function are connected.

INPUT SIGNAL/ROTATION SPEED

The input signal is directly 
proportional to the efficacy of the 
rotor, which implies that input signal 
and rotation speed are as per the 
adjacent diagram.

CHECKS BEFORE POWERING UP THE CONTROL UNIT

Check that

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

Adjustment of max. 
speed

Set the High Speed DIP switch to the ON position. 
Adjust "Max rpm" so that the rotor rotates at 10-12 rpm 
(or as per rotor manufacturer's directions).

Checking minimum 
speed

Set the Low Speed DIP switch to ON. 
Check that the rotor starts. 
The minimum speed is preset. 

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. 
After switching on the voltage the rotor rotates for 20 seconds at 12 rpm 
on the motor. 

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 rotor at maximum and minimum 
rotation speeds and checking that the operating rotor speed is correct. 

COMMISSIONING THE EQUIPMENT

Should be accomplished in sequence

Input signal - rotation speed

Rotation speed (%)

Input signal 0-10 V
