Model AVC Sensing Module
Part Number 9488800100
INTRODUCTION
The AVC Sensing Module provides a convenient and
cost-effective method for expanding the applications
where AVC63-12 and AVC125-10 voltage regulators
can be applied. The AVC Sensing Module increases
the nominal sensing voltage of style BX AVC63-12
and AVC125-10 voltage regulators from 200/240 Vac
to 480 Vac or 600 Vac. The AVC Sensing Module is
compatible with nominal sensing frequencies of
50/60 Hz and 400 Hz.
A compact, rugged (potted) case enables the AVC
Sensing Module to be mounted directly on the
generator. Other than making connections during
installation, the AVC Sensing Module requires no
adjustment or calibration.

MOUNTING
The AVC Sensing Module is housed in a potted,
plastic case that can be mounted in any convenient
position. Overall module dimensions and panel
drilling dimensions are illustrated in Figure 1.
Mounting Hardware
The AVC Sensing Module can be mounted directly
on a genset using #10-32 or equivalent hardware. A
lock washer should be used between the screw head
and body of the module. Torque applied when
tightening the mounting hardware should not exceed
25 inch-pounds (2.8 N
•m).
CONNECTIONS
All AVC Sensing Module connections are located on
the back panel. Sensing voltage is applied to the
lower, six-position terminal block. Sensing voltage is
supplied to the voltage regulator from the upper,
three-position terminal block. Connections consist of
#6 terminal screws. Each terminal accepts a
maximum wire size of 12 AWG (13 mm
2 ). When
securing connections, apply no more than 9 in-lb
(1 N
•m) of torque to each terminal screw.
Before connecting the module, review the terminal
descriptions listed in Table 1 and the connection
diagram of Figure 2. At any given time, only one of
the two sets of sensing voltage input terminals can be
used. Under no circumstance can both the 480 Vac
and 600 Vac sensing input terminals be connected to
a voltage source.
