2-2 SCP 250 Controls 911000099Y Rev T
Locator Control Description
B Var/Power Factor Adjust Control. This control is used to establish the var level or power
factor, depending on the position of the mode switch. The control has two sets of calibration
marks—one set for var control and one set for power factor control. The power factor
calibration marks shown in Figure 2-1 are for an SCP 250-M and will differ from the power
factor calibration marks on an SCP 250-G.
C VAR Range Control. This single-turn potentiometer calibrates the SCP 250 when the mode
switch is the VAR position. Var calibration is described in Section 5, Operation.
D Output Limit Control. This single-turn potentiometer adjusts the control output of the SCP
250. The output is adjustable from approximately ±1 Vdc (fully counterclockwise) to
approximately ±3 Vdc (fully clockwise) or ±9 Vdc (jumper removed from terminals X and Y).
This causes a corresponding change in generator output voltage of about ±10% to ±30%
when the generator is isolated from the bus.
E Balance Control. This single-turn potentiometer is ordinarily set at its midrange position. It
can be adjusted to attain extra precision in the maintenance of power factor in peaking
service over a wide range of kW loading. Use of the balance control is described in Section
5, Operation.
