Power Factor Step Response - Power Factor Setpoint (Nominal).
This read-only field indicates the PF
setpoint. (The PF setpoint is set by using the Setpoint tab of the Setting Adjustments screen.) The value
displayed in the FCR Setpoint field is selected by clicking the adjacent pushbutton. Clicking this button
sends the PF setpoint value to the DECS-100 and changes the color of the pushbutton from gray to red.
Power Factor Step Response - Increment of PF Setpoint.
This field indicates the new PF setpoint that is
established when the corresponding increment button is clicked. Any setpoint value within range or higher
than the existing setpoint value can be typed into the "Increase PF Setpoint =" field. The PF setpoint
changes to this value when the adjacent button is clicked. When clicked, the Increment button changes
from gray to red to indicate that the PF setpoint has increased to the value in the "Increase PF Setpoint ="
field.

Power Factor Step Response - Decrement of PF Setpoint.
This field indicates the new PF setpoint that is
established when the corresponding decrement button is clicked. Any setpoint value within range or lower
than the existing setpoint value can be typed into the "Decrease PF Setpoint =" field. The PF setpoint
changes to this value when the adjacent button is clicked. When clicked, the Decrement button changes
from gray to red to indicate that the PF setpoint has decreased to the value in the "Decrease PF Setpoint
=" field.
Power Factor Step Response - PF Value.
This field and the dial pointer indicate the value of the selected
PF setpoint. When the PF setpoint is changed by clicking the increment, decrement, or setpoint button,
the meter value field and dial pointer indicate the new setpoint value. A new PF setpoint can be typed
directly into the "PF Value" field or selected by dragging the dial pointer to the desired value. The new
value is sent to the DECS-100 by clicking the Send button.
Power Factor Step Response - Current Setpoint.
The active DECS-100 setpoint (adjusted by using any of
the previously mentioned methods) is displayed in this field. To return the PF setpoint to the nominal
setting, the button adjacent to the PF Setpoint (Nominal) field should be clicked. If the PF tab is left to
view other tabs or screens without returning the PF setpoint to nominal, a PF setpoint dialog box appears.
Clicking the Yes button returns the AVR setpoint to nominal. Clicking No maintains the AVR setpoint at
the current value.
