Cause
Positive terminal of EVP1 (pin A29)
is supplied by terminal PIN (pin A13)
through an embedded high-side switch.
The alarm occurs in case terminal A13
is not connected to the battery or the
voltage is different from that defined by
parameter SET POSITIVE PEB (see the
ADJUSTMENTS list).
At key-on, the logic board measures
a voltage value of the KEY input that
is constantly out of range, below the
minimum allowed value.
This alarms occur when there is an
overload on the MC driver (pin A27) or
on the right EB driver (pin A28). As soon
as the overload condition disappears,
the alarm will be removed automatically
by releasing and then enabling a travel
demand.
The controller receives from the CAN
bus the message that another controller
in the net is in fault condition; as a
consequence the controller itself cannot
enter into an operative status, but it has
to wait until the other node comes out
from the fault status.
The analogue reference for the drive
speed is not within the MIN VACC ÷
MAX VACC range, programmed through
the PROGRAMM VACC function.
The acquired values MIN VACC and MAX
VACC are inconsistent.
At start-up, the hardware circuit
dedicated to enable and disable the
EV drivers is found to be faulty. The
hexadecimal value "XX" facilitates Zapi
technicians debugging the problem.
At start-up, the hardware circuit
dedicated to enable and disable the EB
driver (output NEB, pin A28) is found to
be faulty. The hexadecimal value "XX"
facilitates Zapi technicians debugging
the problem.
No load is connected between the NLC
output (pin A27) and the positive voltage
(for example, +KEY).
Section 5 – Procedures
Troubleshooting
Check pin A13: it must have battery
voltage (after master contactor)
Check harness and that the contactor
is working correctly.
Check that the battery has the same
nominal voltage of the inverter Check
the battery voltage, if it is out of range
replace the battery.
If the battery voltage is ok, replace
the controller
The typical root cause is in the wiring
harness or in the load coil.
Check if any other device on the CAN
bus is in fault condition.
Acquire the maximum and minimum
values through the PROGRAM VACC
function. If the alarm is still present,
check the mechanical calibration and
the functionality joystick.
If the problem is not solved, replace
the joystick.
This fault is related to internal
components. Replace the controller.
This type of fault is not related to
external components replace the
controller.
Check the wiring, in order to verify
if LC coil is connected to the
right connector pin and if it is not
interrupted.
If the alarm is still present, than
the problem is inside, replace the
controller.
