M-2271B Adapter Panel – Specification

The M‑2271B is an adapter panel which, when combined with the M‑2001

Series Digital Tapchanger Control, provides convenient direct replacement

for Siemens (Siemens‑Allis and Allis‑Chalmers) and TSEA Toshiba regulator

controls.

Interface

External connections are made via a wiring harness that connects from a

sixteen‑position terminal block to the existing quick disconnect terminal block

on the Siemens control cabinet, or the existing terminal block on the TSEA

Toshiba control cabinet. The Siemens harness may be ordered with the optional

10 position male pin PDS Connector Half.

An additional terminal block 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. 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.
