Call-Out Description
D Operating Point Indication. This LED is lit during normal generator operating conditions. It
turns off when the CBS 212A is providing current boost to the exciter field. The LED turns
on again when the generator output voltage increases above the Operating Point
Adjustment setting.
E Operating Point Adjustment. This screwdriver-adjusted control is used to set the lower limit
(pickup point) of the generator output voltage. If the generator voltage decreases below
this setting, current boost is initiated until the generator voltage increases above the
dropout point. For 120 Vac nominal sensing, dropout occurs when the sensed generator
output voltage increases to 5 volts above the Operating Point Adjustment setting. For 240
Vac nominal sensing, dropout occurs when the sensed generator output voltage increases
to 10 Vac above the Operating Point Adjustment setting.
Note
An Operating Point Adjustment setting that is too close to the nominal
generator output voltage may cause oscillation of the output voltage. If
oscillation occurs, rotate the Operating Point Adjustment control
counterclockwise until the oscillation stops.
