ECO Mode: Enables or disables the Energy Optimization Mode feature for all rectifiers.
When enabled, the following parameters can be set.
Energy Save Pt: Energy Optimization is disabled if the load is greater than this setting.
Best Oper Point: Percent of full load capacity that the rectifiers operate under in the
Energy Optimization mode.
Fluct Range: If load fluctuation is less than this value, rectifiers are not turned on or off
for Energy Optimization.
Cycle Period: This is the time period that rectifiers are turned on and off to maintain an
equal operating time for all rectifiers in the system.
Rects ON Time: Time all rectifiers are turned on at End of Cycle.
Turn Off Delay: When the Energy Optimization feature determines a rectifier can be
