Reactive Power Control (VAR) – DECS Setpoint. This read-only field displays the DECS-400 setpoint as
entered in the var setpoint field.

Reactive Power Control (VAR) – Setpoint. This setting, expressed in kvar, establishes the reactive power
setpoint for var mode. The range of this setting depends on the generator settings and the Min and Max
settings for the Reactive Power Control setpoint.

Reactive Power Control (VAR) – Min (% of rated). This setting defines the generator minimum var
setpoint and is expressed as a percentage of the generator rated VA output. A setting of –100 to 0% may
be entered in 0.1 percent increments.

Reactive Power Control (VAR) – Max (% of rated). This setting defines the generator maximum var
setpoint and is expressed as a percentage of the generator rated VA output. A setting of 0 to +100% may
be entered in 0.1 percent increments.

Reactive Power Control (VAR) – Traverse Rate. This setting determines the time required for the var
setpoint to be adjusted from the minimum value to the maximum value of the adjustment range. A setting
of 10 to 200 seconds may be entered in 1 second increments.

VAR Pre-position 1 – Setpoint. The first pre-position (predefined) generator output terminal voltage
setpoint for var mode is entered in this setting field. The setting range is identical to that of the var
setpoint.

VAR Pre-position 1 – Mode. This setting determines whether or not the DECS-400 will respond to further
var setpoint change commands once the operating setpoint is driven to the pre-position 1 value. Two
mode settings are available in the pull-down menu: Maintain and Release. If Maintain is selected, further
setpoint change commands are ignored. If Release is selected, subsequent setpoint change commands
are accepted to raise and lower the var setpoint.

VAR Pre-position 1 – Traverse Rate/Enable. When enabled, this setting controls the amount of time
required to drive the operating setpoint to the reactive power pre-position 1 setpoint.

VAR Pre-position 2 – Setpoint. The second pre-position (predefined) generator output terminal voltage
setpoint for var mode is entered in this setting field. The setting range is identical to that of the var
setpoint.
