Description
"This alarm occurs if a traction movement is requested
and if the inputs DEAD MAN, SIDE GATE LEFT and
SIDE GATE RIGHT read by the CAN tiller are released.
Moreover, this alarm occurs also if a pump movement is
requested and DEAD MAN, SIDE GATE LEFT and
SIDE GATE RIGHT read by the CAN tiller are released.
Troubleshooting :
Do again the traction/pump movement request with the
switches reported above closed."
"This alarm occurs when the switch input ENABLE
MAINTENANCE is closed.
Troubleshooting :
Release the switch input ENABLE MAINTENANCE."
"This alarm occurs when the ACE0 doesn't receive a
display CAN message for more than 1 minute.
Troubleshooting :
Check the CAN network harness and if the other
modules connected to the CAN network are fully
functioning."
"This alarm occurs if the safety contact managed by the
EPS (whose state is sent via CAN from the EPS to the
ACE0) is already closed during the initialization phase
where the diagnosis is done.
Troubleshooting :
Check the harness and if the alarm still remains then it
could be a problem inside the controller, which has to be
changed."
"This alarm occurs if the safety contact managed by the
EPS (whose state is sent via CAN from the EPS to the
ACE0) remains opened after the initialization phase.
Troubleshooting :
Check the harness and if the alarm still remains then it
could be a problem inside the controller, which has to be
changed."
CAN Tiller has to read 6 potentiometers signals : 2
signals for the fork lift & lower, 2 signal for the accelerator
and 2 signals for the cabin lift & lower. All these
information are sent to the ACE0 via CAN, and the
ACE0 checks the coherence between the signal couple.
If one of these 3 couples show an incoherence between
the 2 signals, this alarm is set.
Troubleshooting :
Check the harness related to the 3 potentiometers and if
the alarm still remains then it could be a problem inside
the controller, which has to be changed.
