645.4.4 Current DemandCurrent demand calculates the demand based on a thermal demand meter.Current demand =(Average of current – last current demand value) × 90%(fixed) + Last current demand valueIn case of that a stable current flows for interval time, 90% of current value is displayed.(%)90intervaltime5.4.5 Max. demand valueMaximum value of measured demand value (active, reactive, apparent, active (export), reactive (export),current)) during 1-month are considered to the max. demand value.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・It stops the demand measurement.・It records monthly max. demand log, max. demand value in the internal memory.・It stops the demand measuring until next span starts. When the next span starts, it will startdemand measuring.Phone: 800.894.0412 - Fax: 888.723.4773 - Web: www.clrwtr.com - Email: info@clrwtr.com |
