EF
Auxiliary coil
short circuit
When the electromagnetic connected to Can#18
output terminal or the auxiliary coil has fault, the fault
occurs. After excluding overload condition, fault is
solved through releasing brake, and thus travel request
is valid.
Fault analysis: generally the fault means the fault
occurs at the harness or loading coil. So check the
connection between controller output and load.
If the outside load does not has fault, then the
controller interior had fault, change the controller.

WATCHDOG #2
Watchdog
fault 2
The watchdog is activated before the software is started
when starting. The watchdog signal is out of effect in
spare use or travelling condition.
Watch dog hardware electric circuit or microcontroller
output part are damage. Change the controller.

TILLER OPEN
Switch open
When the input switch is open, the main contactor
opens after about 30s and the fault occurs. The fault
disappears in next travelling.

fault
When the safety input switch is open, the main
contactor opens and electromagnetic or auxiliary output
coil is driven. Check if the connection of A11 is correct.
If all outskirt is all right, change the controller.

Main
contactor coil
short circuit
Reason: when short circuit coil of the main contactor is
connected to can#16 output terminal, the fault occurs.
The fault disappear after the over load is removed
through releasing brake. Then the travelling request is
valid.
Fault analysis: generally, the fault means the fault
occurs at harness or load coil, so check the connection
between the controller output and load.
If the outside load does not has fault, then the controller
interior had fault, change the controller.

Key
switch
short circuit
During start stage, when the contactor detects low
logical level signal when the key switch is open, the
fault occurs.
Fault analysis: it may be caused by low voltage.
-
Key switch is based on outside load (such as the
start of DC-DC converter; the input signal of relay
or contactor is lower than start voltage.)
