Page 6: Description Of Functions
DESCRIPTION OF FUNCTIONS • The VariMax25 NG is part of a new range of control units that, with the necessary additional functions, are suitable for the optimum control of rotary heat exchangers. The series comes in two sizes, the VariMax25 NG and VariMax50 NG. Both the control units operate 3-phase stepper motors. -
Page 7: Mounting
Continued from previous page • As an alternative, the VariMax25 NG can have an external rotation monitor (magnet mounted on the rotor with an associated rotation monitor). This is connected at terminal connections 9 and 10, and the DIP switch for the “External rotation monitor” should be in the ON position. -

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". -
