INTRODUCTION
The Basler APR 63-5 Voltage Regulator is a
CSA/UL approved unit contained in an encap-
sulated plastic case. The regulator controls
the dc exciter field power of conventional, 50
or 60 hertz brushless generators that have a
63 Vdc field to regulate the output voltage.
Regulation is provided by sensing the genera-
tor output voltage, converting it to a dc signal
and comparing the signal to a reference volt-
age signal. An error signal is developed and
used to control the dc field power in order to
maintain a constant generator output.

OVEREXCITATION SHUTDOWN
If the exciter field voltage exceeds 100 ±5 Vdc,
the regulator automatically removes the field
current after a time delay. The time delay is
inversely proportional to the magnitude of the
detected overvoltage condition. At approxi-
mately 135 ±5 Vdc, the field voltage is removed
instantaneously. Refer to the following figure.
Upon detection of overexcitation and the re-
sulting field voltage shutdown, the regulator
will not reset or return to an operational condi-
tion until the generator output drops to less
than 6 Vac for 10 seconds minimum.

REGULATOR CONTROLS
FREQ CONTROL
This control prevents generator and regulator
damage by dropping the generator output volt-
age when the generator frequency drops.
a. Set generator RPM to desired frequency
roll-off.
b. Adjust FREQ control until voltage starts
to drop off.
c. Speed up generator to rated speed. Volt-
age should be at nominal.
STAB CONTROL
This control allows the generator response
time (and thus voltage stability) to be adjusted.
Use an oscilloscope or other voltage record-
ing device to set this control.
a. Rotation of STAB control CW will slow
voltage response time.
b. Rotation of STAB control CCW will speed
response time. If rotated too far, genera-
tor voltage will hunt (oscillate).
c. Rotate STAB control CW just past point
where voltage oscillation occurs.
VOLT CONTROL
Rotation of VOLT control CW will increase gen-
erator output voltage.
Removing jumper (terminals 6 and 7) and con-
necting external potentiometer (1,000 ohms,
2 watts) allows a ±10% adjustment of voltage
range with nominal set by VOLT control.
INTERCONNECTION
Refer to the following interconnection dia-
grams.
a. Connect the jumper from COM to either
the 50 Hz or 60 Hz terminal depending
upon the generator frequency.

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 6and 7as 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.

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 3and 4. If
the voltage is greater than 6 Vac, voltage
buildup should occur. Repeat flashing if
less than 6 Vac residual is measured.
