Troubleshooting
1. Check whether the CAN
communications cable and
build-out resistor are
correctly connected. If not,
rectify the fault.
2. Exchange the slot of the
faulty module with that of a
normal module. If the fault
occurs only in the original
slot, the slot is abnormal and
needs to be handled.
3. Exchange the slot of the
faulty module with that of a
normal module. If the fault
occurs again after the slot
exchange, replace the faulty
module or contact the
technical support.
1. Check whether the output
port of the charging module
is short-circuited.
2. Replace the faulty module.
1. Check whether the air
channel of the charging
module is seriously blocked. If
yes, rectify the fault.
2. Check whether the output of
the charging module is short-
circuited. If yes, rectify the
fault.
3. Exchange the slot of the
faulty module with that of a
normal module. If the fault
occurs only in the original
slot, the slot is abnormal and
needs to be handled.
4. Exchange the slot of the
faulty module with that of a
normal module. If the fault
occurs again after the slot
exchange, replace the faulty
module or contact the
technical support.
