VKEY OFF
SHORTED
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.
1- Check that the battery has the
same nominal voltage of the inverter.
2- Check the battery voltage, if it is
out of range replace the battery.
3- If the battery voltage is ok, replace
the logic board.
221
HANDBRA
KE
Handbrake input is active.
1- Check that handbrake is not active
by mistake.
2- Check the SR/HB input state
through the TESTER function.
3- Check the wirings.
4- Check if there are failures in the
microswitches.
5- If the problem is not solved,
replace the logic board.
222
SEAT
MISMATC
H
This alarm can appear only in a Traction
+ Pump configuration or in a multimotor
one. There is an input mismatch
between the traction controller and the
pump controller relatively to the
TILLER/SEAT input (A1): the two values
recorded by the two controllers are
different.
"1- Check if there are wrong
connections in the external wiring.
2- Using the TESTER function, verify
that the seat inputs are in accordance
with the actual state of the external
switch.
3- In case no failures/problems have
been found, the problem is in the
controller, which has to be replaced.

COIL
SHOR.
MC (For
Combi
AC0/Combi
ACX and
ACE4)
This alarm occurs when an overload of
the MC driver
1- Check the connections between
the controller outputs and the loads.
2- Collect information about
characteristics of the coil connected
to the driver and ask for assistance to
a EP technician in order to verify that
the maximum current that can be
supplied by the hardware is not
exceeded.
3- In case no failures/problems have
been found, the problem is in the
controller, which has to be replaced.
