Load control monitor object can be total instantaneous active power(import + export), total
instantaneous import active power, total instantaneous export active power, Maximum current in
three phase, Maximum active power in three phase.
Overload disconnect logic:
When load is higher than the preset threshold A and duration the preset delay time B, relay
will disconnect, relay status turns from connected to ready for reconnection
After relay is disconnected, it will keep this status for a preset time C, relay will turn
connected and detect the load again
If overload counts more than D times, relay will not execute off/on again, relay will keep the
initial status(consumer can decide to turn off or on by himself), this initial status called G.
If overload does not happen in E minutes, the meter will restart the overload counts.
