SAFETY INSTRUCTIONS
“Safety instructions” refers to instructions whose specic
intent is to avoid the risk of personal injury and to prevent
damage to equipment.
Danger! Electrical current to electrical components!
Note: Switch o main power before removing the cover.
Never touch electrical components or contacts while main
current is switched on. Risk of electric shock, resulting in
serious injury or death.
Connected terminals contain residual voltage even aer
the main current has been switched o.
e following symbols and references will be used in this description.
ese important instructions apply to personal protection and technical safety
during operation.

• e MicroMax180 is part of a range of control units adapted, with the necessary
additional functions, for optimum control of rotary heat exchangers.
e series consists of ve 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.
• MicroMax180 is designed for rotors up to 2500 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 eciency are governed by the control unit
so that rotor speed is proportional to the input signal from the control centre.
• MicroMax180 has a adjustable threshold value of 0-2 V.
• MicroMax180 has adjustable boost function.
• MicroMax180 has a rotation monitor (magnet mounted on the rotor with
associated magnetic sensor) and built-in cleaning function.
e functions can be disconnected via DIP switches.
• MicroMax180 starts automatically following voltage
drop-out and resets all alarms on restart.
• e motor should not be disconnected from the control unit while under load.

TECHNICAL DATA
FUNCTIONS
6

DIP SWITCH
Cleaning function Cleaning function connected in ON position.
When the rotor has stopped for 30 minutes, the cleaning function is
activated and the rotor rotates at minimum rpm for 10 seconds.
Rotation monitor Rotation monitor set to ON position.
High speed*) e rotor rotates at the set maximum rpm when the switch is set to ON.
Aer a test run, make sure the DIP switch is set to OFF.
Low speed*) e rotor rotates at the xed minimum rpm when the switch is set to ON.
Aer a test run, make sure the DIP switch is set to OFF.
*) Manual operation (test mode)
OPERATIONAL INDICATIONS
On/alarm Lit with xed light
It ashes when the control unit has tripped.
Run Comes on when the motor is to rotate, i.e. when the input signal exceeds
the threshold value.
Rotation Flashes when the magnet passes the magnetic sensor, regardless of the
“Rotation monitor” DIP switch setting.
Flashes even if the input signal is lower than the threshold value.

Rotation monitor
Probable fault cause on
installation
Probable fault cause in
operation
Alarms and trips if a pulse is not received every 5 minutes.
- Magnet turned the wrong way
- Rotation monitor incorrectly connected (wrong polarity),
refer to “Connections” on page 10
- Too wide a gap between the magnetic sensor and magnet, max 15 mm
-Broken belt
- Belt slipping
- Stuck rotor
- Magnetic sensor or magnet not intact
Overtemperature motor
Probable fault cause
Alarms and trips if motor winding temperature is too high.
e thermal contact in the motor reverts to normal mode when the
temperature drops.
See "Overcurrent" on page 9.
Overvoltage Alarms and trips if the connection voltage exceeds 276 V
for more than 4-5 seconds.
Undervoltage Alarms and trips if the connection voltage drops below 195 V
for more than 4-5 seconds.
Short circuit/overcurrent
Probable fault cause
Alarms and trips in the event of a phase-to-phase or phase-to-earth
short circuit and overcurrent.
Short circuit phase-phase or phase-earth (earth fault)
MicroMax180 trips immediately.
- Motor winding fault
Measure motor resistance, it should be identical on all phases.
- Short circuit between phases in the cable
- Earth fault in the motor or cable
ALARMS
All alarms remain in state.
