SAFETY INSTRUCTIONS
Safety instruction refers to instructions whose specic 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.
Residual voltage remains in connected terminals
even aer main power has been switched o.
e following symbols and references are used in this description. ese instructions
are important; they apply to personal and technical safety during operation.

•MiniMax (enclosed IP54) is a modern, vector modulated frequency converter, with the
additional functions necessary for optimum control of rotating heat exchangers.
e control unit can handle all input signals currently used in the market.
•Heat exchanger rpm and thus thermal eciency 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.
•e rotation monitor (a magnet tted 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.
•e control unit restarts automatically following a power failure.
•e motor should not be disconnected from the control unit while under load.
•e control unit can be equipped with extra cards. e following cards are available:
- Dierential temperature regulator with electrical heating output
- 2-rotor module

Cleaning
1
Cleaning function set to ON position.
When the wheel has stopped for
30 minutes, the cleaning function is
activated and the wheel rotates at
minimum speed for 10 seconds.
Rotation monitor 1 Rotation sensor set to ON position.
High speed* 1e wheel rotates at the set maximum
rpm when the switch is set to ON.
Low speed* 1e wheel rotates at the set minimum
rpm when the switch is set to ON.
*) Manual operation (test mode)
OPERATIONAL INDICATIONS
On "Power on" is lit continuously.
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
during installation
Probable fault cause
during operation
Alarms and trips unless a pulse is received every 5 minutes.
- Magnet facing the wrong way
- Magnetic sensor incorrectly connected; see “Connections” on
pages 11 -12.
- Too wide a gap between the magnetic sensor and magnet; max 15 mm
-Broken belt
- Belt slipping
- Stuck wheel
- Magnetic sensor or magnet not intact
Overtemp. 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 input voltage exceeds 276 V for more than
4-5 seconds.
Undervoltage Alarms and trips if the input voltage falls below 195 V for more than
4-5 seconds.
ALARMS
All alarms remain in state.
