Note:
*,Once this error occurs,need according to the troubleshooting to remove the cause of failure and then
to electricity back on.
▲
,They are severe protection faults.If such faults are repeated three times within 60min, the corresponding
systems fail to automatic recovery,and they must be recovered after troubleshooting in power failure.
√
,can be automatically restored after troubleshooting
Note:
1. If the master unit malfunctions, the master unit stops, without impact on other units (except for flow
switch fault).
2. If the slave unit malfunctions, only this unit stops, without impact on other units.
