70 195 CHARGER ON Battery charger in operation
mode The alarm is normally present when the system is switched
on and the battery charger is in operation: all movements
are disabled.
Check that the NC mains contact, inside the battery charger,
is closed and that the wiring for connecting the contact to
the controller is correct.
71 210 WRONG RAM MEM. RAM memory error This type of error is not related to external components, so if
present, replace the controller.
72 30 VMN LOW Drive motor phase voltage too
low
A) If the problem occurs at start-up (line contactor open),
check:
- The internal connections of the motor (ohmic continuity);
- Power cable connections of the motor;
- Loss of insulation between the motor and vehicle chassis;
If motor connections are OK, the problem is inside the
controller
B) If the alarm occurs during motor operation, check:
- Motor connections;
- If the motor winding / cables phases have insulation
losses toward the machine chassis;
- If the power contact of the line contactor goes off correctly
and keeps a solid contact;
If motors do not have any problems, the fault is in the
controller.
72 207 INIT VMN LOW Initial drive motor phase voltage
too low Please check
- The internal connections of the motor (ohmic continuity);
- Power cable connections of the motor;
- Loss of insulation of the motor on vehicle chassis;
If motor connections are OK, the problem is in the controller,
which must be replaced.
74 74 DRIVER SHORTED Short circuit on line contactor coil
output
A) Check if there is a short circuit or low impedance
between NLC CNB # 6 and -BATT.
B) The driver circuit is be damaged in the controller, which
must be replaced.
C) The LC line contactor coil wires are broken or not
connected, then check the coil.
75 75 CONTACTOR
DRIVER
Error on line Contactor output This type of error is not related to external components;
replace the controller.
75 75 CONTACTOR
CLOSED
Error on line Contactor output It is recommended that you check the LC line contactor
power contacts;
Replace the LC line contactor if necessary.
75 75 CONT. DRV. EV. Error on the solenoid valve driver
circuit The device or its driver circuit is damaged, replace the
controller.
76 223 COIL SHOR. MC-EB Contactor/electric brake control
short circuit
A) The main typical cause of this error code is in the wiring
or in the coil. Then check the connections of the controller
outputs.
B) If no failures / problems outside are detected, the
problem is in the controller, which must be replaced.
77 38 CONTACTOR OPEN Line contactor open It might be due to a contact problem in the LC line contactor
that does not work (no pull-in); try replacing the line
contactor.
78 78 VACC NOT OK Drive potentiometer not
calibrated
If the alarm appears at the machine start-up, the initial
calibration of the drive potentiometer must be executed.
If the alarm is displayed with the machine already calibrated,
check the mechanical calibration and functionality of the
drive potentiometer.
