Description
"This alarm occurs when both a Lifting request and a
Lowering request are active at the same time. Pump
motor is stopped.
Troubleshooting :
Check the wiring of the Lifting/Lowering pair. A failure in
the logic is possible too. When you have checked the
Lifting/Lowering switches are fine working and the wiring
is right, it is necessary to replace the controller."
It occurs when the voltage on CNA#4 (NK1: Lower
potential terminal of the safety contacts is higher than 12
V before to turn the safety contacts closed. When the
safety contacts are open, the voltage on CNA#4 is
expected to be close to 0 Vdc and this is independent
from whether the safety contacts are connected to a plus
battery or to a minus battery. In the first case (safety
contacts connected to a plus battery), when the safety
contacts are open, CNA#4 is connected to a minus
battery through a load. Only a harness mistake may
connect NK1 to a higher than 12 V voltage.
"There are 4 switches that give information about the
position of the forks; two of these switches are read by
the ACE0 and two of these are read by the CAN Tiller
and their status are sent via CAN to the ACE0. This
alarm occurs if there is any inconsistency between the
status of these switches. These switches are normally
closed (when the forks are in the lower position) and if,
for instance, switch 4 is released (because the forks are
in the higher position) but either switch 1 or switch 2 or
switch 3 is closed, then this allarm occurs (switch 1 is the
lower one, while switch 4 is the higher one). This alarm
causes the truck to stop.
Troubleshooting : Check the harness related to the 4
switches (CNA-7 and CNA-6 of the ACE0 and CNC-1
and CNC-4 of the CAN Tiller). If the state of these inputs
is right, then it could be a problem inside the controller,
which has to be changed."
"This alarm occurs when the ACE0 doesn't receive the
enable signal from the display; this enable signal is sent
by the display after the password is entered.
Troubleshooting :
This fault could be determined by a problem in the truck
Canbus line or by an internal problem in the display logic
card. It is suggested to preliminary check Canbus
connection. The alarm does not occur if the display is set
to off in the Set options menu."
