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"
189
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."
191
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."
192
PUMP VACC
RANGE
for COMBIAC0 and COMBIACX）it
means the output of lift pot is out of
the normal range
193
SMARTDRIVER
KO
There is a hardware problem in the
smart driver circuit . The driver is
set to be ON but the output voltage
does not increase
"1- Verify that the EB coil is connected
correctly between pin A2 and pin A4.
2- Verify that the parameter POSITIVE
E.B.is set in accordance with the
actual configuration (see paragraph
8.2.5). The software, in fact,
depending on specific parameter value,
makes a proper diagnosis; a
wrong configuration of this parameter
could generate a false fault.
3- In case no failures/problems have
been found, the problem is in the
controller, which has to be replaced."
