FCR Pre-position 1 – Traverse Rate/Enable. When enabled, this setting controls the amount of time
required to drive the operating setpoint to the FCR pre-position 1 setpoint. The rate setting establishes the
length of time for the setpoint to travel the full setting range.
FCR Pre-position 2 – Setpoint. The second pre-position (predefined) field current setpoint for FCR mode
is entered in this setting field. The setting range is identical to the FCR setpoint.
FCR Pre-position 2 – Mode. This setting determines whether or not the DECS-400 will respond to further
setpoint change commands once the operating setpoint is driven to the pre-position 2 value. The
available mode settings are identical to mode settings for pre-position 1.
FCR Pre-position 2 – Traverse Rate/Enable. When enabled, this setting controls the amount of time
required to drive the operating setpoint to the FCR pre-position 2 setpoint. The rate setting establishes the
length of time for the setpoint to travel the full setting range.
Field Voltage Regulator (FVR) – DECS Setpoint. This read-only field displays the DECS FVR setpoint as
entered in the FVR setpoint field.
Field Voltage Regulator (FVR) – Setpoint. When operating in FVR (Manual) mode, this setting establishes
the field dc voltage setpoint. The Setpoint range depends on the Field Type setting (Configure screen,
Options tab) and the associated ratings.
Field Voltage Regulator (FVR) – Min (% of rated). This setting, expressed as a percentage of rated field
voltage, establishes the minimum field voltage setpoint. A setting of 0 to 150 percent may be entered in
0.1 percent increments.
Field Voltage Regulator (FVR) – Max (% of rated). This setting, expressed as a percentage of rated field
voltage, establishes the maximum field voltage setpoint. A setting of 0 to 150 percent may be entered in
0.1 percent increments.
Field Voltage Regulator (FVR) – Traverse Rate. This setting determines the time required for the FVR
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.
FVR Pre-position 1 – Setpoint. The first pre-position (predefined) field voltage setpoint for FVR mode is
entered in this setting field. The setting range is identical to the FVR setpoint.
FVR Pre-position 1 – Mode. This setting determines whether or not the DECS-400 will respond to further
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 FVR setpoint.
FVR Pre-position 1 – Traverse Rate/Enable. When enabled, this setting controls the amount of time
required to drive the operating setpoint to the FVR pre-position 1 setpoint.
FVR Pre-position 2 – Setpoint. The second pre-position (predefined) field voltage setpoint for FVR mode
is entered in this setting field. The setting range is identical to the FVR setpoint.
FVR Pre-position 2 – Mode. This setting determines whether or not the DECS-400 will respond to further
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 FVR setpoint.
FVR Pre-position 2 – Traverse Rate/Enable. When enabled, this setting controls the amount of time
required to drive the operating setpoint to the FVR pre-position 2 setpoint.
VAR/PF
VAR/PF tab functions are shown in Figure 41 and described in the following paragraphs.
Fine Voltage Adjustment Band. This setting, expressed as a percentage of the generator nominal voltage,
defines the upper and lower boundaries of voltage correction during var or power control. A setting of 0 to
30 percent may be entered in 0.01 percent increments.
