(e) Set BATTERY CIRCUIT SELECTOR switch (S6, fig 2-2) to OFF.
(f) Set FIELD CIRCUIT switch (S32, fig 2-2) to REGULATOR
position. This will give regulated voltage, provided regulator has
been properly adjusted.
(g) Set MILLIVOLT METER MILLIVOLT DROP RANGE switch (S16, fig
2-1) to Xl position.
(h) Apply specified load to generator, press MILLIVOLT METER
MILLIVOLT DROP PRESS TO READ switch S34, fig 2-1) and note millivolt
drop across contacts for a given load. (Refer to equipment manufac-
turer's test procedure. )
(i)
Perform other tests required by manufacturer's specifica-
tions.
( j ) Upon completion of tests, set MASTER LOAD DISCONNECT
switch (S8, fig 2-2) to OFF.
Set FIELD CIRCUIT switch (S32, fig 2-2) to OFF.
(k)
(25) Reduce varidrive speed to one-quarter speed by turning
SPEED CONTROL (fig 2-4) clockwise, and stop varidrive by pressing STOP
pushbutton switch (S2).
(Refer to fig
c. Testing Generator-Regulator (Positive Ground).
NOTE
This test procedure is only a typical procedure.
(1) Position test stand controls in accordance with table 2-1.
(2) Install regulator on regulator mounting bracket located on
the right hand corner of test stand, and adjust to desired position.
(3) Install batteries in battery compartment (4, fig 4-3) of
test stand, and connect to proper binding posts on terminal board as-
(4) Set BATTERY CIRCUIT SELECTOR switch (S6, fig 2-2) to the
proper voltage for system under test.
(5) Set DC VOLTMETER OUTPUT VOLTAGE SELECT switch (S11, fig 2-1)
to BAT. Set MASTER LOAD DISCONNECT switch (S8, fig 2-2) to ON posi-
tion. Make certain that battery voltage is same as volts e of system
under test. Then, set BATTERY CIRCUIT SELECTOR switch (S6)to OFF,
and set DC VOLTMETER OUTPUT VOLTAGE SELECT switch (S11, fig 2-1) to
RECT GEN position. Place MASTER LOAD DISCONNECT switch (S 8, fig 2-2)
to OFF position.
