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 instructions” 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 rotary heat exchanger Type designation MicroMax Article number F21009301 EU directive The manufacturer's declaration of conformity with the applied to the requirements of the EMC Directive 2004/108/EC.
All of the control units drive three-phase induction motors with associated gearing, the control unit designation denotes motor output. All control units have an input signal of 0-10 V. MicroMax is designed for wheels up to 1500 mm with a wheel speed of • max 12 rpm.
TECHNICAL DATA Connection voltage 1x230-240 V +/-15% Ambient temperature, -25 - +45 50/60 Hz non condensing Power input, max. 210 W Protection form IP54 Input current, max. 0.9 A Weight 0.9 kg External fuse, max. 10 A Dimensions, HxWxD 158x165x60 mm Exact value cannot be obtained with a digital measuring Output voltage*) 3x0-230 V...
DIP SWITCH Cleaning function 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 rpm for 10 seconds. Rotation monitor Rotation monitor set to ON position. High speed*) The wheel rotates at the set maximum rpm when the switch is set to ON.
Alarms and trips in the event of a phase-to-phase or phase-to-earth overcurrent short circuit and overcurrent. Short circuit phase-phase or phase-earth (earth fault) MicroMax trips immediately. Probable fault cause - Motor winding fault Measure motor resistance, it should be identical on all phases.
Continued from previous page Overcurrent MicroMax limits current at 1.2 A and trips then after 4-5 s. Probable fault cause - The motor is too small in relation to wheel diameter - Wheel rotation sluggish - Damaged motor, e.g. bearing fault Measure current.
CONNECTION DIAGRAM U V W 13 14 15 9 10 1x 230 V 3x 230 V Thermal Alarm relay 0 -10 V Rotation contact monitor (Max 2 A / 250 V AC) CONNECTIONS Switch off power before starting work on the equipment. Recommended tightening torque on terminals 0.5 Nm, max tightening torque 0.8 Nm.
CHECKS BEFORE POWERING UP THE CONTROL UNIT Check that the control unit is connected as per instructions on page 10. Connection 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/7G0.75 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.
