F21037601 - IBC Control MiniMax - Thermal Wheel Rotary Control Unit

• MiniMax (enclosed IP54) is a modern, vector modulated frequency converter, with the additional functions necessary for optimum control of rotary heat exchangers.The control unit can handle all input signals currently used in the market.

• Heat exchanger rpm and thus thermal efficiency are governed by the control unit so that wheel speed is proportional to the input signal from the control centre.

• If the input signal is less than the set threshold value the rotor is stopped.

• When the rotor has been at a standstill for 1/2 hour, cleaning begins and the rotor turns for 10 seconds at minimum rpm.

• MiniMax has an adjustable threshold of 20% of the input signal´s maximum value.

• MiniMax has adjustable boost function.

• The rotation monitor (a magnet fitted to the rotor with an associated magnetic sensor) stops the converter and generates an alarm in the case of a broken belt or similar.

• In the event of over- or under voltage on the mains, short circuit or earth fault and tripped thermal contact in the motor, the control unit trips and generates an alarm.

• MiniMax starts automatically after voltage drop-out, and resets all alarms on restart.

• The motor should not be disconnected from the control unit while under load.

• The control unit can be equipped with extra cards.
