Page 6: Description Of Functions
• The VariMax50 NG has an integrated input signal offset, which means rotor efficiency is proportional to the input signal. • The VariMax50 NG threshold is set at 0.1 V (hysteresis 0.13 - 0.07 V). If the input signal drops below this value, the rotor will stop. - Page 7 • The VariMax50 NG starts automatically following a power failure, and resets all alarms upon restarting. • The VariMax50 NG is a stepper motor with high torque throughout its speed range. • The VariMax50 NG motor has no built-in thermal contact. The control unit regulates power and makes sure the motor will not overheat.

Page 9: Dip Switch
DIP SWITCH Cleaning function Cleaning function connected in ON position. When the rotor has stopped for 10 minutes, the cleaning function is activated and the rotor starts to rotate. As advance warning, the rotor rotates with a motor speed of 5 rpm for the first 6 seconds, following which the rotor stops for 3 seconds. -
Page 10: Alarms
ALARMS In the case of an alarm, the control unit will restart after 30 seconds. The relevant red LED will light up for the same period of time (30 seconds). After restart, the LED is extinguished; this takes place twice. The third time, the alarm relay closes and the alarm "moves on". -
