IBCcontrol MicroMax750, Manual

Page: 7 / 16

•
The MicroMax750 is part of a range of control units adapted, with the necessary
additional functions, for optimum control of rotary heat exchangers.
The series consists of five sizes, MicroMax, MicroMax180, MicroMax370,
MicroMax750 and MicroMax1500.
All of the control units drive three-phase asynchronous motors with associated
gearing, the control unit designation denotes motor output. All control units
have an input signal of 0-10 V.
•
MicroMax750 is designed for rotors up to 5000 mm with a rotor speed of
max 12 rpm.
If a faster rotor speed is necessary, rotor diameter should be reduced.
•
Heat exchanger rpm and thus thermal efficiency are governed by the control unit
so that rotor speed is proportional to the input signal from the control centre.
•
MicroMax750 a adjustable threshold value of 0-2 V.
•
MicroMax750 has adjustable boost function.
•
MicroMax750 has a rotation monitor (magnet mounted on the rotor with
associated magnetic sensor) and built-in cleaning function.
The functions can be disconnected via DIP switches.
•
MicroMax750 starts automatically following voltage
drop-out and resets all alarms on restart.
•
The motor should not be disconnected from the control unit while under load.
