204 "VACC NOT
OK"
Warning: Accel-
erator siganal
(CPOT) voltage
higher than
VAC C M I N + 1 V
While the trac-
tion enable
switch is open
PUMP • This fault indicates that the accelerator
voltage is 1volt greater than the mini-
mum value programmed by PROGRAM
VACC function.
• The potentiometer is not correctly cali-
brated.
• The potentiometer is defective.
• Tilt or sideshift switch activated at star-
tup
205 "INCOR-
RECT
START"
Warning: Wrong
traction request
sequence
PUMP • This fault indicates an incorrect starting
sequence.
• Lift or enable switch failure
• Error in sequence made by operator.
• Incorrect wiring.
• If the fault persist after checking the wir-
ing,
• Pot partially activated at startup
Replace con-
troller
206 "PEDAL
WIRE KO"
Fault in Accelera-
tor negative
(NPOT) Input cir-
cuit.
PUMP • Check accelerator wiring and connec-
tions for opens
• Check accelerator input voltage using
PcConsole handset in tester mode (volt-
age should range from xx VDC to
approx. xx VDC).
207 "MOTOR
TC START"
Warning: Pump
motors tempera-
ture high
PUMP • Pump motor analog temperature sensor
is greater than the temperature set in
ADJUSTMENT #4 (130°C) in the
ADJUSTMET submenu.
• When this fault occurs, current goes
down to IMX PROTECTION value and
motor rpm begins to decrease. Motor
current and speed decrease linearly as the
temperature increases until MOTOR-
SHUTDOWN is reached.
• If it happens when the motor is cold,
check the wring. If all is ok,,
Check tempera-
ture shown on
handset in tester
mode
Replace con-
troller
