EEPROM KO Damage of
programmable
memorizer
Fault in the area of memory in which the adjustment
parameters are stored; this alarm inhibits machine
operation. If the defect persists when the key is
switched OFF and ON again, replace the logic. If the
alarm disappears, remember that the parameters stored
previously have been cancelled and replace by the
default values.

This alarm signals that an undervoltage /overvoltage
protection operation has occurred. The voltage detected
by controller higher than 65V or lower than 11V.
Possible causes:
1. Short circuit in electric system, such as DC-DC,
brake coil or check if the controller input power to earth
is well connected.
2. Over low or over high of battery voltage
3. Check if the cables on binding post such as B+, B
and main contactor are firmly connected.
4. Check if the calibration parameter of the controller
voltage agrees with the actual voltage.
5. Fault of logic board hardware electric circuit on over
voltage protection, change controller

VMN LOW VMN LOW MOS high-end voltage lower than 66% of compactor
voltage or lower than the required value during running
Possible causes:
1. incorrect wiring or fault of motor circuit; check
if the three phase connecting of the motor is correct;
check if the motor to earth leaks; check if the motor coil
has broken circuit.
2. Check if the main contactor is firmly connects
and the connecting points are worn.
3. Change controller

VMN HIGH VMN HIGH When turning on the key switch, MOS lower end
voltage is higher than 10% of the normal battery
voltage or phase voltage higher than 1/2 of the battery
voltage.
Possible causes:
1. incorrect wiring or fault of motor circuit; check
