b.
Remove the jumper and connect termi-
nals CB– and CB+ to the CBS 305 inputs
(if used). If the CBS 305 is not being used,
leave the jumper in place.
c.
If an external voltage adjust control is
being used, connect the potentiometer to
terminals 6 and 7 as shown. If not, con-
nect a jumper between terminals 6 and 7.
d.
Connect the exciter field to terminals F+
and F–. Be sure to observe polarity.
e.
Connect the input power to the genera-
tor stator to provide power to terminals 3
and 4. Fuse both leads. Install the op-
tional shutdown switch, if desired.
f.
Connect the sensing input to either 240
or 480 depending on voltage. The sens-
ing should be connected line-to-line.

OPERATION
The following system operation procedures
provide instructions for adjusting the APR 63-
5 Voltage Regulator.
CAUTION
Meggers and high potential test equipment
must not be used. Incorrect use of such
equipment could damage the semiconduc-
tors contained in the regulator.
PRELIMINARY SETUP
To prevent damage to the regulator, complete
the following steps before proceeding with
system startup.
a.
Verify that the voltage regulator specifi-
cation conforms with the generator sys-
tem requirements.
b.
Ensure that the regulator is correctly
connected to the generator. See inter-
connection diagram.
c.
Install fuses per
FUSES paragraph.
During periods of prime mover idling, use the
excitation shutdown switch.
SYSTEM STARTUP
a.
Start the prime mover and bring it up to
rated speed. Voltage should build up. If a
minimum residual of 6 Vac is not present,
perform field flashing.
b.
Slowly adjust VOLT control until voltage
reaches nominal value. If used, adjust
remote voltage adjust to set generator
output to exact value desired.
c.
Apply and remove load to check stability.
Adjust per
STAB CONTROL paragraph
if voltge is unstable.
d.
Reduce generator frequency (speed) to
55 Hz (on 60 Hz systems) or 45 Hz (on
50Hz systems). Check that generator
output decreases from this point. If it does
not, adjust per
FREQ CONTROL para-
graph.
ACCESSORY EQUIPMENT
Power Isolation Transformer - BE 18674 001
Parallel Compensation - APM2000 and Cur-
rent Transformer
Manual Voltage Control - MVC-300
Current Boost System - CBS305 and Current
Transformer
OPERATIONAL TEST
a.
Connect the test setup as shown below
and apply 240 Vac as shown.
b.
Adjust the VOLT control fully CCW. Ob-
serve that the lamp is not lit.
c.
Adjust the VOLT control fully CW. Ob-
serve that the lamp is lit.
d.
Adjust the VOLT control until the lamp
just goes out.

Operational Test Setup
FIELD FLASHING
When the regulator is operated with the gen-
erator for the first time, the polarity of residual
magnetism may not be correct or the magni-
tude may not be enough. If the generator does
not build up, shut down the prime mover and
proceed as follows.
a.
With the prime mover at rest, apply a dc
source (not grounded) of not more than
48 Vdc to terminals F+ and F– in series
with a limiting resistor. Use 1 ohm of re-
sistance for each volt from the dc source
with a power rating of at least 1 watt per
volt.
b.
Allow approximately 30 seconds before
removing the dc source.
c.
Start the prime mover and measure the
voltage at the regulator leads 3 and 4. If
the voltage is greater than 6 Vac, voltage
buildup should occur. Repeat flashing if
less than 6 Vac residual is measured.
