Beckwith Electric M-2286 Adapter Panel

Adapts M‑2001 Series Digital Tapchanger Control to Replace Westinghouse

MS and TM LTC Transformer Control Panels

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

mounting screws and 24‑pin connector

• Replaces MS and TM panels, fits directly into existing control cabinet cutout

and quickly plugs into existing connectors

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

Tapchanger Control is removed

The M‑2286 is a replacement panel which, when combined with the M‑2001

Series Digital Tapchanger Control, provides convenient direct replacement for

Westinghouse MS and TM Control Panels. The M‑2286 mounts directly into

the existing cutout in the control cabinet, and includes the M‑2067B Adapter

Panel with a voltage fuse and two terminal blocks on the rear for external

connections.

The M‑2286 also includes an M‑0169A Auxiliary Current Transformer that

contains sockets for existing MS and TM connectors.

Interface

External connections are made to two terminal blocks located on the rear of

the M‑2067B Adapter Panel. An additional terminal block provides access to

auxiliary functions, including self‑test alarm, user‑programmable alarm, manual

raise/lower and operations counter.

Features

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

A relay TEST/OPERATE toggle switch with INDICATOR LIGHT for CONTACT

CLOSURE; and a cam switch auxiliary relay (used only for non‑sequential

operation) are standard.

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 fungus growth.
