86 PEDAL WIRE
KO
The SW continuously checks for
the connection of the two sup-
ply ends of the potentiometer
in the accelerator. The test
consists of reading the voltage
drop on a sense diode, con-
nected between NPOT
(CNA#30) and GND and cas-
caded with the potentiometer:
if the potentiometer gets dis-
connected on PPOT (NNA#25)
or NPOT, no current flows in
the sense diode and the volt-
age on the NPOT connection
colla[pses down. When the
NPOT voltage is less than 0.3V
this alarm occurs. This alarm
also occurs when the NPOT
voltage is higher than 2Vdc (to
detect the condition of a bro-
ken sense diode).
Check the Voltage on NPOT and the potenti-
ometer connections.
51 TILLER OPEN Warning: When the tiller is
released, after a fixed period of
time of standby (30 seconds)
the main contactor open.
At the next travel request, the warning will dis-
appear.
92 CURRENT GAIN The Maximum current gain
parameter are at the default
values, which means the maxi-
mum current adjustment pro-
cedure has not been carried
out yet.
Ask the assistance of a Zapi technician to do
the correct adjustment procedure of the
current gain parameters.
68 WAITING FOR
NODE
The controller receives from the
CAN the message that another
controller in the net is in fault
condition; as a consequence
the ACOE controller itself can-
not enter an operative status,
but has to WAIT for the other
controller coming out from the
fault status.
