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 automatic recovery,and they must be recovered after troubleshooting in power
failure.
√ ,can be automatically restored after trouble
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.
