The parameters to be configured are:
The Lo value : when the unit exceeds this value for 30 minutes, alarm E08 is
triggered, and if alarm E11 is enabled, the Controller MASTER control VAR FAST unit
enters No Connection status and activates alarm E11.
The HI value: if the unit exceeds this value for 30 seconds, alarm E08 is triggered,
and if alarm E12 is enabled, the Controller MASTER control VAR FAST unit enters
Disconnection status and activates alarm E12.

to the normal operating status.

disconnect them if the operation requires it.
