Error Message Possible Cause Fault Elimination
Code Error Text
48 EVP DRIVER KO The EVP valve driver is not able
to drive the load (cannot
close).
The device or its driving circuit is damaged,
replace the controller.
47 EVP2 DRIVER
KO
The EVP2 valve driver is not able
to drive the load (cannot
close).
The device or its driving circuit is damaged,
replace the controller.
56 PUMP I NO
ZERO
In staNdby condition (pump motor
not driven), the feedback com-
ing from the current sensor in
the pump chopper gives a
value out of a permitted range.
This type of fault is not related to external
components; replace the controller.
52 PUMP I=0 EVER This test is carried out when the
pump motor is running, and it
verifies that the current feed-
back sensor is not constantly
stuck to 0.
This type of fault is not related to external
components; replace the controller.
49 LIFT + LOWER This alarm occurs when both fork
movement requests (Lift +
Lower) are active at the same
time.
Check the wiring of the lift and lower inputs
(use the readings in the TEST to facilitate
the troubleshooting). Check the micros-
witches for failures.
A failure in the logic is possible too. So, when
you have verified the travel demand
switches are working fine and the wiring is
right, it is necessary to replace the control-
ler.
