PUMP
VACC
NOT OK
Cause:
The minimum voltage of the lift potentiometer is not correctly set.
Troubleshooting:
It is suggested to repeat the acquiring procedure of MIN LIFT and MAX LIFT (see
paragraph 9.2).
189
PUMP
INC
START
Cause:
Man-presence switch is not enabled at pump request.
Troubleshooting:
- Check wirings.
- Check microswitches for failures.
- Through the TESTER function, check the states of the inputs are coherent with
microswitches states.
- If the problem is not solved, replace the logic board.

PUMP
VMN
NOT OK
Cause:
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
paragraph 8.2.1
–
HYDRO SETTINGS). If the voltage is too low, this alarm
occurs.
Troubleshooting:
Please check:
- 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.
- Motor internal connections
- Motor power cables connections
- Motor leakage to truck frame
- If the motor connections are ok, the problem is inside the controller it is
necessary to replace the logic board.
191
PUMP I
NO ZERO
Cause:
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.
Troubleshooting:
This type of fault is not related to external components; replace the controller.
192
PUMP
VACC
RANGE
Cause:
The voltage on A30 is outside of the parameters range.
Troubleshooting:
If the EVP TYPE parameter is set to ANALOG , please acquire again the values of
MIN LOWER and MAX LOWER.
If the controller is in configuration COMBI and lifting is proportional, please
acquire again also the values of MIN LIFT and MAX LIFT.
193
SMART
DRIVER
KO
Cause:
There is a hardware problem in the smart driver circuit . The driver is set to be ON
but the output voltage does not increase
