TABLE OF CONTENTS

Warning indication e control unit must be in perfect technical condition

before use.

Damage that can aect safety must be remedied

immediately.

Maintenance/Repairs e function of the control unit should be checked regularly.

Troubleshooting and repairs may only be performed by trained

personnel.

Prescribed electrical protection must be implemented.

Disposal and recycling When replacing components or when the control unit in its

entirety need replacing, please follow the advice below:

e aim should always be maximum possible

recycling of raw materials, with minimum possible

environmental impact.

Never dispose of electrical components with ordinary waste,

always use the designated collection points.

Disposal should be as environment-friendly as the technology

allows in terms of environmental protection and recycling.

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.

Connected terminals contain residual voltage even aer

the main current 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 rotary 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

rotor 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.

• 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.

• MiniMax starts automatically aer voltage drop-out,

and resets all alarms on restart.

• 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

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 speed for 10 seconds.

Rotation monitor 1 Rotation monitor set to ON position.

High speed *) 1e rotor rotates at the set maximum

rpm when the switch is set to ON.

Low speed *) 1e rotor 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 if a pulse is not received every 5 minutes.

- Magnet turned the wrong way

- Rotation monitor incorrectly connected; refer to “Connections” on

pages 11 -12.

- 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

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 connection voltage exceeds 276 V for more than

4-5 seconds.

Undervoltage Alarms and trips if the vonnection voltage falls below 195 V for more

than 4-5 seconds.

ALARMS

All alarms remain in state.
