INSTALLATION INSTRUCTIONS Warning indication The control unit may only be used in perfect technical condition. Any damage that may affect safety must be dealt with immediately. Maintenance/Repairs The function of the control unit should be checked regularly. Troubleshooting and repairs may only be performed by trained personnel.
SAFETY INSTRUCTIONS The following symbols and references will be used in this description. These important instructions apply to personal protection and technical safety during operation. Safety instruction refers to instructions whose specific intent is to avoid the risk of personal injury and to prevent damage to equipment.
MANUFACTURER'S DECLARATION Manufacturer IBC control AB Brännerigatan 5 A, SE-263 37 Höganäs, Sweden Product Control unit for rotating heat exchanger Type designation MicroMax370 Article number F21037401 EU directive The manufacturer's declaration of conformity with the requirements of the applied to the EMC Directive 2004/108/EC.
All control units have an input signal of 0-10 V. • MicroMax370 is designed for wheels up to 3500 mm with a wheel speed of max 12 rpm. If a faster wheel speed is necessary (15-25 rpm), wheel diameter should be reduced.
TECHNICAL DATA Input voltage 1x230-240 V +/-15 % Overload 1 min/30 min 3.5 A 50/60 Hz Internal fuse **) 10 AT Power input, max. 650 W Acceleration time (Fixed) 30 sec Input current, max. 2.8 A Retardation time (Fixed) 30 sec Incoming fuse, max.
DIP SWITCH The default DIP switch setting is 100 Hz. Max frequency To increase speed, the DIP switched may in special cases be set to 150 Hz 100/150 Hz This may however result in a shorter service life for the VVX motor. Cleaning Cleaning function set to ON position.
Undervoltage and over- circuit and overcurrent. voltage both light up Phase-to-phase short circuit MicroMax370 limits current to 4 A, above which it will trip after 4-5 seconds. Probable fault cause - Motor winding fault Measure motor resistance; it should be identical on all phases.
In the event of an earth fault, the control unit must be reset with power off. ------------------------------------------------------------------------------------------------------ Overcurrent MicroMax370 limits current to 4 A, above which it will trip after 4-5 seconds. Probable fault cause - The motor is too small in relation to wheel diameter - Wheel rotation sluggish - Damaged motor, e.g.

CHECKS BEFORE POWERING UP THE CONTROL UNIT Check that the control unit is connected as per instructions on page 10. Input voltage 230-240 V +/-15%, 50/60 Hz. Check that the motor is wired for 3 x 230 V. If there is an operating switch between the motor and the control unit, the motor thermal contact should be connected via the auxiliary terminal in the operating switch.
EMC INSTALLATION Incoming EKK 3G1.5 Magnetic sensor, LiYCY 2x0.34 Not shielded Shielded Motor cable Input signal, LiYCY 2x0.34/0.5 Ölflex Classic 110 CY/7G0.5 Shielded Shielded EMC glands must be used for shielded cables. The above cables or equivalent must be used to comply with the EMC Directive. EMC GLAND NOTE! When connecting the shield to the EMC gland, it is important to do so as shown above.
