LOGIC FAILURE
#1
This fault is displayed when the
controller detects an undervoltage
condition at the key input (A1).
Undervoltage threshold depends on
the nominal voltage of the
controller.
Fault at startup or in standby:
- Fault can be caused by a key
input signal characterized by
pulses below the undervoltage
threshold, possibly due to external
loads like DC/DC converters
starting-up, relays or contactors
18
LOGIC FAILURE
#2
Fault in the hardware section of the
logic board which deals with voltage
feedbacks of motor phases.
The failure lies in the controller
hardware. Replace the controller.
17
LOGIC FAILURE
#3
A hardware problem in the logic
board due to high currents
(overload). An overcurrent condition
is triggered even if the power bridge
is not driven.
The failure lies in the controller
hardware. Replace the controller.
220
VKEY OFF
SHORTED
The logic board measures a key
voltage that is constantly out of
range, below the minimum allowed
value.
- 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.
- In case the problem is not solved,
replace the logic board.
230
LC COIL OPEN
This fault appears when no load is
connected between the NLC output
(A16) and the positive voltage (for
eKEY).
- 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 the logic
board;
replace it.
