Warning

When something abnormal but not serious happens, the PWS2-30K will report a warning.

Usually a warning will not cause PWS2-30K to stop, unless the warning is caused by the power. For example, if the grid voltage drops to 0 due to an AC disconnect shut-down by someone.

For the PWS2-30K, utility voltage down is reversible, but without utility voltage to support the PWS2-30K to continue operation, the PWS2-30K will shut down and report warning (actually there should be 2 warnings because AC voltage contains amplitude and frequency). And when the utility voltage restores, the PWS2-30K will start again automatically without EMS command.
