Details compliance with EMC Directive 2004/108/EG and low voltage directive 2006/95/EG.
Use shielded cable for motor and control signal, connect screen at both ends.
Explains the MiniMax V/VK inverter's function in controlling rotating heat exchangers.
Provides technical specifications including motor size, current, voltage, and dimensions.
Controls cooling recycling, sets adjusted max speed when run (5-6) is closed.
Controls defrosting, sets adjusted min. speed when run (5-6) is closed.
Adjusted to central control, supporting various voltage and current signals.
0-10VDC input relates to 0-100Hz for rotor speed proportionality.
Must be closed if external start is not being used.
Must be closed if thermal contact in motor is not used.
Monitors rotor for belt breakage or disorders, stops inverter and gives alarm.
Remote reset of alarm; inverter resets automatically when input power is disconnected.
Connected between 14-15 when alarm or power is off.
Connected between 16-17 when run is enabled, max 8A/250V AC.
Allows testing of motor rotation at adjusted maximum and minimum speeds.
Adjusts low speed torque; may increase motor temperature if increased.
Sets time of acceleration (0-30 sec), adjusted to max before delivery.
Sets retardation time (0-30 sec), adjusted to max before delivery.
Inverter starts when speed signal exceeds threshold, adjustable 0-20% of max input.
Sets minimum speed (1-20Hz), adjusted before delivery to 4 Hz.
Sets maximum speed (40-100Hz), adjusted before delivery to 50 Hz.
Details DIP-switch settings for various input signals and functions.
Verify motor connection, inverter wiring, input power, DIP-switch, and monitor connections.
Check motor rotates correctly in relation to the rotor rotating direction.
Adjust 'Max rpm' using 'High speed' pushbutton or A1-A2 and 'Run' 5-6.
Adjust 'Min rpm' using 'Low speed' pushbutton or A2-A3 and 'Run' 5-6.
Verify rotation monitor function; yellow LED flashes when magnet passes transmitter.
Adjust threshold value on central control to stop rotor if it continues rotating.
Check cleaning function operation when power is on and speed reference is low.
Run rotor at max and min speeds via central control and verify correct speeds.
Explains status indicated by Green, Yellow LED 1, and Yellow LED 2.
Details conditions indicated by Red LED 1, 2, 3, 4, and 3+4 for various faults.
Inverter trips at 250V (over) or 190V (under) with 7 sec delay.
Inverter limits current to 4.0 Amps.
Inverter limits current during short circuits between phases or phase/earth.
Rotor rotates at min. speed for 10 sec. every 30 min. if idle below threshold.
Automatic restart after failure; disconnection of motor under load is not allowed.
Troubleshoots issues causing inverter trips, like rotation monitor or thermal contact faults.
Diagnoses why rotor lacks power to start or gain speed, e.g., acceleration ramp, motor size.
Guides on checking drive, speed signal, operation conditions, and output voltage.
