The maximum demanded value is stored in non-volatile memory. It is not cleared when the relay is turned off. When the
relay is turned on again, the maximum values are updated.
States associated to the demand (“Actual>Status>Records Status>Demand”) are the following:

Besides the previously considered demand measures, two states are used for demand control:
DEMAND TRIGGER INP Bit type state, Programmable at “Setpoint>Relay Configuration>Protection Elements” in the
EnerVista 650 Setup software. This signal is used by the Block Interval demand method.
DEMAND RESET INP Bit type state, programmable at “Setpoint>Relay Configuration>Protection Elements” in the
EnerVista 650 Setup software. When this bit is activated, the demand measures are reset. All
stored values are reset to zero (for demand dates, this value represents January 1
st
