MANY PUMP
REQ.
if there's more than one pump
function request,e.g. lift+tilt,the
alarm occrus
1-check the microswitches status
2-check the wiring of pump functions
3-disconnect the wire on the controller
side
4-If the problem is not solved, replace
the logic board.
188
PUMP VACC
NOT OK
The minimum voltage of the lift
potentiometer is not correctly
set.
1-It is suggested to repeat the
acquiring procedure of MIN LIFT and
MAX LIFT
2-check the wiring of the lift pot
3-check if it's the lift pot fault

PUMP INC
START Man-presence switch is not
enabled at pump request
1- Check wirings.
2- Check microswitches for failures.
3- Through the TESTER function,
check the states of the inputs are
coherent with microswitches states.
4- If the problem is not solved, replace
the logic board.
190
PUMP VMN NOT
OK
Switching the LC on, the
software checks the output
voltage on -P connector, and
expects that it is at a “steady
state” value (if DC PUMP option
is set to ON, see
HYDRO SETTINGS). If the
voltage is too low, this alarm
occurs.
1- The motor connected to -P must be
completely still before this alarm
occurs. The software waits 30
seconds before showing this alarm.
During this time it shows the WAIT
MOTOR STILL warning.
2- Motor internal connections
3- Motor power cables connections
4- Motor leakage to truck frame
5- If the motor connections are ok, the
problem is inside the controller it is
necessary to replace the logic board.

PUMP I NO
ZERO
In standby condition (pump
motor not driven), the feedback
coming from the current sensor
in the pump chopper gives a
value out of a permitted range,
because the pump current is not
zero.
This type of fault is not related to
external components; replace the
controller.
