INTRODUCTION

The AVC Sensing Module provides a convenient and cost-effective method for expanding the applica tio ns where AVC63-12 and AVC125-10 voltage regulators can be applied. The AVC Sensing Module incr eases 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 fr equ encies 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 illust rated 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

). 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 connect e d to a voltage source.
