Description
Cause :
It occurs when the battery charge is calculated being
less than or equal to 10% of the full charge and the
BATTERY CHECK setting is other than 0 (refer to SET
OPTION menu).
Troubleshooting :
Get the battery charged. If it doesn't work, measure with
a voltmeter the battery voltage and compare it with the
value in the BATTERY VOLTAGE parameter. If they are
different adjust the value of the ADJUST BATTERY
function.
"If the" "battery check" "option is ON, a battery discharge
algorithm is carried out. When the charge level is 10%,
this alarm is signalled and the current is reduced to the
half of the programmed level.Troubleshooting: recharge
the battery."
This alarm occurs if the circuit to limit via hardware the
current in the motor is either always active at key-on or
repeatedly active when the motor is turning. Check the
motor is suited to work with the eps-ac 0 (not oversized).
Otherwise it is necessary to replace the controller.
This alarm occurs when the current in the phase V of the
motor is zero and the motor is commanded for moving.
Check the power fuse is OK. Check the battery positive
arrives to the controller. Check the continuity of the wire
in the phase V of the motor. Otherwise it is necessary to
replace the controller.
This alarm occurs when the current in the phase U of the
motor is zero and the motor is commanded for moving.
Check the power fuse is OK. Check the battery positive
arrives to the controller. Check the continuity of the wire
in the phase U of the motor. Otherwise it is necessary to
replace the controller.
This alarm occurs when the current in the phase W of
the motor is zero and the motor is commanded for
moving. Check the power fuse is OK. Check the battery
positive arrives to the controller. Check the continuity of
the wire in the phase W of the motor. Otherwise it is
necessary to replace the controller.
Cause :
The driver of the main contactor coil is shorted or the coil
is disconnected.
Troubleshooting :
A)
Check if there is a short or a low impedance pull-down
between NMCC (CAN#12) and -BATT.
B)
The driver circuit is damaged in the controller, which
has to be replaced.
C)
The wires to the LC coil are interrupted or not
connected, so check the coil related harness.
