SAFETY INSTRUCTIONS
Safety instruction 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.
Residual voltage remains in connected terminals
even aer 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 eciency 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:
- Dierential 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* 1e wheel rotates at the set maximum
rpm when the switch is set to ON.
Low speed* 1e 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.

Short circuit
Probable fault cause
Probable fault cause
Alarms and trips in the event of short circuit phase-phase, phase-earth
and overcurrent.
Short circuit phase-phase or
phase-earth (earth fault)
MiniMax 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 motor or cable
Overcurrent
MiniMax limits current at 4 A and trips then aer 4-5 s.
- e motor is too small in relation to wheel diameter
- Wheel rotation sluggish
- Damaged motor, e.g. bearing fault
Measure current.
NOTE! Precise voltages and amperages can only be obtained with a
moving-iron instrument.

PUTTING THE EQUIPMENT INTO OPERATION
Should be done in sequence.
Check that the motor rotates in the right direction in relation to the wheel's direction
of rotation.
In the event of a fault, switch two phases to the motor.
Setting max speed Set the “High speed” DIP switch to the ON position.
Adjust "Max rpm" so that the wheel rotates at 10-12 rpm
(or as per wheel manufacturer directions).
Aer a test run, set the DIP switch to OFF.
Setting min speed Set the “Low Speed” DIP switch in the ON position.
Adjust "Min rpm" so that the wheel rotates at 0.2-1 rpm
(or as per wheel manufacturer directions).
Aer a test run, set the DIP switch to OFF.
Checking the cleaning
function
Switch o the voltage.
Make sure the cleaning DIP switch is set to ON
and the input signal is disconnected.
When power is switched on, the wheel will rotate at minimum rpm for
10 seconds.
Checking the
rotation monitor
e yellow Rotation LED will ash when the magnet passes
the magnetic sensor, regardless of DIP switch position.
Setting the threshold
value
Make sure the control centre is connected. Jump "Run" 5-6.
Set the minimum output signal on the control centre.
If the rotor continues to turn, increase the threshold value until it stops.
Finish by allowing the control unit to drive the wheel at maximum and minimum
rotation rpm and checking that wheel rpm is correct.
13
Check that the DIP switch is set for the type of signal the control equipment outputs.
See “DIP switch” setting, page 7.
Check that the cleaning function and rotation sensor DIP switch are set to ON.
