5.4.4 Current Demand

Current demand calculates the demand based on a thermal demand meter.
Current demand =
(Average of current – last current demand value) × 90%(fixed) + Last current demand value
In case of that a stable current flows for interval time, 90% of current value is displayed.

5.4.5 Max. demand value

Maximum value of measured demand value (active, reactive, apparent, active (export), reactive (export),

It records the max. demand value of each time-zone and all time for 12-month.

5.4.6 Demand alarm output

・It output with pulse output terminal. (open collector)
・It output only when [AL-PD] is set for unit for pulse output.
・It doesn't output alarm if power demand alarm threshold is set to '0.000'kW.

5.4.7 Working at power failure and at recovery

<At power failure>
・It stops the demand measurement.
・It records monthly max. demand log, max. demand value in the internal memory.
<At recovery>
・It stops the demand measuring until next span starts. When the next span starts, it will start
demand measuring.
