Beckwith Electric M-2356B Adapter Panel

The M-2356B is an adapter panel which, when combined with the M-2001 Series

Digital Tapchanger Control, provides convenient direct replacement for General

Electric ML-32 balance beam regulator controls. The M-2356B consists of a front

panel and two wiring harnesses with octal plugs which mount into the control

cabinet. All mounting hardware from the faceplate and socket housing of the

original control must be saved , including: the two wing nuts, the two thumbscrews

and C-clips, and two nuts, washers and bolts.

• Connects easily to the M-2001 Series Digital Tapchanger Control using mounting

screws and 24-pin connector

• Fits directly into existing regulator control cabinet using the same mounting

hardware from the faceplate and socket housing of the original control

• Provides built-in CT shorting protection when the M-2001 Series Digital Tapchanger

Control is removed

Tapchanger Control, provides convenient direct replacement for General Electric ML‑32

Interface

External connections are made via two wiring harnesses with octal plugs that mount

through the octal sockets onthe existing control cabinet. Most connections come from

a fifteen‑position terminal block on the printed circuitboard and a four‑position terminal

block to the octal plugs. An additional terminal block (TB2) on the printed circuit board

provides access to auxiliary functions, including self‑test alarm, user‑programmable alarm,

auto disable and manual raise/lower.

Features

Separate fuses for test terminal, voltage sensing and motor power are on the front panel.

Spare fuses for each are in the fuse holder.

Binding posts on the front panel allow easy connections for test procedures.

RAISE/OFF/LOWER, AUTO/OFF/MANUAL and VOLTAGE SOURCE switches, DRAG HANDS

RESET button, and NEUTRAL LIGHT are standard.

NEUTRAL LIGHT will light to indicate that the regulator is in the neutral position, for those

products equipped with a circuit for this purpose.
