VAR Pre-position 2 – 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 2 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 2 – Traverse Rate/Enable. When enabled, this setting controls the amount of time
required to drive the operating setpoint to the reactive power pre-position 2 setpoint.
Power Factor Control (PF) – DECS Setpoint. This read-only field displays the DECS power factor setpoint
as entered in the PF setpoint field.
Power Factor Control (PF) – Setpoint. This setting establishes the operating power factor for the
generator. The Setpoint setting range is determined by the PF (Leading) and PF (Lagging) settings.
Power Factor Control (PF) – PF (Leading). The minimum desired leading power factor level is entered in
this setting field. A setting of –1.000 to –0.500 may be entered in 0.005 increments.
Power Factor Control (PF) – PF (Lagging). The minimum desired lagging power factor level is entered in
this setting field. A setting of 0.500 to 1.000 may be entered in 0.005 increments.
Power Factor Control (PF) – Traverse Rate. The power factor setpoint traverse rate is entered in this
setting field. This setting determines the time required to adjust the AVR setpoint 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.
PF Pre-position 1 – Setpoint. The first pre-position (predefined) power factor setpoint is entered in this
setting field. The setting range is identical to the power factor setpoint.
PF Pre-position 1 – Mode. This setting determines whether or not the DECS-400 will respond to further
setpoint change commands once the power factor 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 power factor setpoint.
PF Pre-position 1 – Traverse Rate/Enable. When enabled, this setting controls the amount of time
required to drive the operating setpoint to the power factor pre-position 1 setpoint.
PF Pre-position 2 – Setpoint. The second pre-position (predefined) power factor setpoint is entered in this
setting field. The setting range is identical to the power factor setpoint.
PF Pre-position 2 – Mode. This setting determines whether or not the DECS-400 will respond to further
setpoint change commands once the power factor setpoint is driven to the pre-position 2 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 power factor setpoint.
PF Pre-position 2 – Traverse Rate/Enable. When enabled, this setting controls the amount of time
required to drive the operating setpoint to the power factor pre-position 2 setpoint.
PF Active Power Level – Level%. This setting establishes the level of generator output power (kW) where
the DECS-400 switches to/from Droop Compensation/Power Factor mode. If the level of power decreases
below the setting, the DECS-400 switches from Power Factor mode to Droop Compensation mode.
Conversely, as the level of power increases above the setting, the DECS-400 switches from Droop
Compensation mode to Power Factor mode. A setting of 0 to 30% may be entered in 0.1% increments.
Startup
Startup tab functions are shown in Figure 42 and described in the following paragraphs.
Soft Start – Soft Start Level (SS Level). This setting, expressed as a percentage of the nominal generator
terminal voltage, determines the starting point for generator voltage buildup during startup. A setting of 0
to 90 percent may be entered in 1 percent increments.
Soft Start – Soft Start Time (SS Time). This setting defines the amount of time allowed for the buildup of
generator voltage during startup. A setting of 1 to 7,200 seconds may be entered in 1 second increments.
