When

vcltcge reyufctor is first put into service, or when ou:put (gcnerai-x-
to-aircraft) cabJes cte changed, the
regulator may
require up to five scparafe
s
adjustmer:fs. The five adiustmenfs are for generator output voltage value,
damping gain, damping rate, line drop compensation gain, and line drop
comper.sation rate.
See Figure 6 for ider.tification of components used for
reguJator adiustment.
.
.
(a) Adiust generator output voltage.
This is a reJativeJy ecsy adjustment to make. Witlt the generator running
at a rated speed (2000 RPM) end rated cycles-per-second (400 Hz}, rotate
the rheostat knob (7) CLOCKWISE to INCREASE voltage and COL!NTER-
CLOCKWJSE to DECREASE voltcge.
Obse,rve the AC voltmeter and adjust
output vohcge to 115 V AC.
(b) Adiust cable length and cabfs size compensation rheostats.
These' two adjustments should be made together. Switch (4., Fig. 6) must lx
ON. Proceed as follows:
(aa) Adjust the rheostat (2) to point to the length, in feet, of output
cable being used.
Various cable lengths are indicated on a plate
mounted behind the rheostat knob.
(bb) Adjust rheostat (3) to point to the size of cable being used. Various
cable sizes are also indicated on a plate behind the rheostat knob.

(cc) With
generator running
(no load), check output voltage value, which
should be oxactJy 115 V AC.
If not, adjust in accordance with Pam.
