which must be saved from the original control.

• Fits directly into existing regulator control cabinet using the existing two hinges

and knurled knob

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

Control is removed

• Optional SCADA Cutout (Local/ Remote) switch (for use with SCADA enabled M-2001C

controls) allows Local Blocking of SCADA commands

• Optional SCAMP™ (SCADA Controllable Auto/Manual Pushbutton) switch replaces

• Optional 2 Level Local Voltage Reduction switch

The M‑2324C is an adapter panel which, when combined with the M‑2001 Series Digital

Tapchanger Control, provides convenient direct replacement for Pennsylvania Transformer

(McGraw‑Edison) Pole Star regulator controls hinged on the right side.

The M‑2324C consists of a front door panel with hinge leaves on the right side and mounts

into the control cabinet using the existing two hinges, and knurled knob which must be

saved from the original control.

Interface

External connections are made via a wiring harness that connects to the terminal block in

the existing control cabinet. Most connections come from a fifteen-position terminal block

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

includes a front door hinge for easy replacement of the control panel.

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

screws and 24-pin connector

• Provides direct mechanical replacement of Allis-Chalmers surface-mount LTC

transformer controls

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

Control is removed

The M‑2278 is an adapter panel which, when combined with the M‑2001 Series

Digital Tapchanger Control,

provides convenient direct replacement for Allis‑Chalmers surface‑mount LTC

transformer controls. The

M‑2278 is designed to mount against a flat surface using four screws and includes

a front door hinge for easy replacement of the control panel.

Interface

External connections are made to a terminal block located on the top of the rear

panel of the M‑2278. Additional connections may be made to two terminal blocks

located on the printed circuit board of the adapter panel.

These terminal blocks 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.

Replaces Westinghouse Type SJS Transformer Control Panel

• Replaces Westinghouse Type SJS voltage regulating relay

and thermal time delay relay

• Wiring harness quickly connects to existing terminal block

• Fully transient-protected

• Will operate properly over a temperature range from –40°

to +80° C

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 mount ing 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.

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.

Options

SCADA CUTOUT switch allows Local blocking of SCADA commands (for use with SCADA enabled M‑2001

controls). Use of the SCADA Cutout switch with the M-2001C, requires a M-2001C Control with firmware

version D‑0146V08.01.22 or later installed.

SCAMPTM (SCADA Controllable Auto/Manual Pushbutton) switch allows the Auto/Manual state on the adapter

panel to be changed by a SCADA command. Use of the SCAMP pushbutton switch with the M‑2001C,

requires a M-2001C Control with firmware version D-0146V08.05.XX or later installed.

Voltage Reduction switch allows 2 levels of Voltage Reduction to be selected.

Testing Specifications

High Voltage: All input and output terminals will withstand 1500 Vac rms to chassis or instrument ground for

one minute with a leakage current not to exceed 25 mA, for all terminals to ground. Input and output circuits

Surge Withstand Capability: All input and output circuits are protected against system transients. Units

pass all requirements of ANSI/IEEE C.37.90.1-1989 defining surge withstand capability.

Radiated Electromagnetic Withstand Capability: All units are protected against electromagnetic radiated

interference from portable communications transceivers.
