Disclaimer
The purpose of this procedure is to verify
the basic functionality of the Autodaptive
®
Regulator Control (ARC). Considering the
inherent Autodaptive characteristics of the
regulator control, such as cumulative behavior
of operating variables, the reproducibility of
some variables may be limited. For additional
information regarding testing of the ARC,
please contact Beckwith Electric Company.
Refer to Chapter 7, M-2802 SLIMcom™ for
SLIMcom operating instructions.

NOTE: This procedure is to be performed
by qualified personnel who are familiar with
the safe operation of test equipment in
substation environments.
6.0 Bench Test
Equipment needed:
• Variable voltage and current source
• 90-145 V ac, 60 Hz
• 0-200 mA, 60 Hz phase locked to
voltage source. Phase angle ad-
justable from 0 to +180°
• High impedance true RMS voltmeter
with accuracy of ±0.2% or better
• AC current meter with accuracy of ±1%
or better
• Two 120 V ac indicator lamps
• PC with SLIMcom software and RS-232
cable
Procedure:
1. Connect the equipment as shown in
Figure 6-1.
2. Apply 120 V ac and verify that the
green OK LED is blinking.
3. Using SLIMcom, check that the
displayed secondary voltage is 120 V
ac ±0.3% with the same voltage applied
to the control.
4. Apply 100.0 mA 0° confirm that the
displayed secondary current is 100.0
mA ±2.0%.
5. Remove the current applied in step 4.
6. Bandcenter check:
a. Set the voltage bandcenter to 120 V.
b. Slowly raise the input voltage until
the green LOWER LED lights.
Record the voltage at which the
LED first lights.
c. Slowly lower the input voltage un-
til the green RAISE LED lights.
d. Record the voltage at which the
LED first lights.
e. The bandcenter should be the mid-
way point between these two volt-
ages.
7. Return the input voltage to 120 V ac.
