68. Error ID: 02A48
Error Description: EVP DRIVER OPEN
Cause A
The driving circuit of the auxiliary coil cannot drive load.
Handling Method:
1)Check whether there is a short circuit or low impedance pulling down the output
between B3 and B2.
2)The drive circuit of the controller failure, replace the controller.
Operation method of replacing the controller is the same as the Error ID 02A00.
69. Error ID: 02A57
Error Description: EVP DRIV. SHORT
Cause A
The driving circuit of the proportional valve coil cannot drive load.
Handling Method:
1)Check whether there is a short circuit or low impedance pulling down the output
between B3 and B2.
2)The drive circuit of the controller failure, replace the controller.
Operation method of replacing the controller is the same as the Error ID 02A00.
66. Error ID: 02A30
Error Description: INIT VMN HIGH
Cause A
Before the contactor is opened, the software will check whether the controller drives it. The
software expects the pull-in voltage to be at a "steady state" value. If it is too high, it will
alarm.
Handling Method:
1) The motor is not connected properly, or there is something wrong with the motor
circuit; check whether the three-phase connection of the motor is correct; whether the
motor has leakage to ground, whether there is motor coil open-circuited.
2) Replace the controller.
67. Error ID: 02A32
Error Description: PUMP VMN NOT OK
Cause A
Before the contactor is opened, the software will check the output voltage of controller -P
and expect it to be in the "steady state" value (The truck type option is set to LEVEL = 1). If
the voltage is too low, it will alarm.
Handling Method:
1) The motor is not connected properly, or there is something wrong with the motor
circuit; check whether the three-phase connection of the motor is correct; whether the
motor has leakage to ground, whether there is motor coil open-circuited.
2) Replace the controller.
