STEER
SENSOR KO
The voltage read by the microcontroller
at the steering-sensor input is not
within the STEER RIGHT VOLT ÷
STEER LEFT VOLT range,
programmed through the STEER
ACQUIRING function
1- Acquire the maximum and
minimum values coming from the
steering
potentiometer through the STEER
ACQUIRING function. If the alarm
is still present, check the
mechanical calibration and the
functionality of the potentiometer.
2- If the problem is not solved,
replace the logic board.

WRONG ENC
SET Mismatch between parameters
ENCODER PULSES 1 and ENCODER
PULSES 2 Set the two parameters with the
same value, according to the
adopted encoder

VDC LINK
OVERV.
This fault is displayed when the
controller detects an overvoltage
condition. Overvoltage threshold
depends on the nominal voltage of the
controller.
Nominal voltage 24V 36/48V 72/80V
96V
Overvoltage threshold 35V 65V 115V
130V
As soon as the fault occurs, power
bridge and MC are opened. The
condition is triggered using the same
HW interrupt used for undervoltage
detection, uC discerns between the
two evaluating the voltage present
across DC-link capacitors:
- High voltage Overvoltage condition
- Low/normal voltage Undervoltage
condition
If the alarm happens during the
brake release, check the line
contactor
contact and the battery
power-cable connection.
208
EEPROM KO the connection of the EEPROM is not
ok
This type of fault is related to
internal components. Replace the
logic board.
