6.3.7 Bat Hi
Meaning: Battery over voltage
Reason: Battery voltage is too high
Solution: 1. When there is a sudden disconnect the battery connection action, the action is very
dangerous, check the battery wiring is reliable.
2. The battery capacity is too small, the charging current relative to the battery is too
high, increase the battery capacity.
3. The battery is damaged, replace the battery.
6.3.8 SYN Acc
Meaning: Synchronous fault
Reason: Grid input phase not SYN with device
Solution: 1. The frequency accuracy of the GRID power supply is poor,do not connect the own
power supply to the device grid input,and the device can not be used to load at the
same time.
2. The grid input excessive ripple interference,installation of input filter.
3.Grid input terminals of the device should not connect the offline without phase lock
power, such as: dual power switch or unlock phase UPS, otherwise phase will
dangerous mutations caused by a short circuit
6.3.9 DCBUS-H
Meaning: DC Bus over voltage
Reason: Bus voltage is too high
Solution: 1. There is a surge voltage input, if the power supply have quality problems, please add
the input surge absorption equipment and filtering device.
2. Output error of active devices, remove suspected load.
3. Output soft short circuit or grounding, check the output circuit.
6.3.10 EEP ROM
Meaning: Storage fault
Reason: Interior storage break down
Solution: Interior fault
6.3.11 Samp-?
Meaning: ADC testing fault
Reason: ADC detection circuit internal fault ("?" can be "1" to "4" arbitrary value)
Solution: Interior fault
6.3.12 CAN M-E
Meaning: CAN communication conflict
Reason: Series parallel device detected more than two units of the master
Solution: 1. The series parallel network can only have one master
