Beckwith Electric M-2302 Adapter Panel

Adapts M‑2001 Series Digital Tapchanger Control to Solid‑State Controls

for Howard Industries SVR‑1

• 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 SCAMPTM (SCADA Controllable Auto/Manual Pushbutton)

switch replaces AUTO/OFF/MANUAL toggle switch

• Optional 2 Level Local Voltage Reduction switch

The M‑2302 is an adapter panel which, when combined with the M‑2001

Series Digital Tapchanger Control, provides convenient direct replacement

of Howard Industries SVR‑1 solid‑state controls. The M‑2302 consists of

a front panel with hinge leaves, and mounts into the control cabinet using

the same two hinge pins which must be saved from the original control.

Interface

External connections are made using a wiring harness that connects from

a sixteen‑position terminal block to the terminal block on the existing control

cabinet. An additional terminal block provides 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, and spare fuses for each are located 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 pushbutton, and NEUTRAL LIGHT are standard.

AUTO/OFF/MANUAL switch may be configured for switch status detection.

NEUTRAL LIGHT will light to indicate that the regulator is in the neutral

position, for those regulators equipped with a circuit for this purpose.

Options

SCADA CUTOUT switch allows Local blocking of SCADA commands (for use

with SCADA enabled M‑2001C controls). The SCADA Cutout switch must

be used with a M-2001 Series 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.

The SCAMP pushbutton switch must be used with a M‑2001 Series 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 are 

electrically isolated from each other, from other circuits and from ground.

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.

Environmental

Temperature Range: Functionality is maintained from -40° to +85° C.

Humidity: Functionality is maintained under 95% relative humidity (non-condensing).

Fungus Resistance: A conformal printed circuit board coating inhibits fungal growth.
