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.

Available Options

SCADA Cutout switch allows the local blocking of SCADA commands (for use

with SCADA enabled M-2001C controls). Use of the SCADA Cutout switch

requires a M-2001C Control with firmware version D‑0146V08.01.22 or later

installed.

SCAMP™ (SCADA Controlled 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 requires a M-2001C Control with firmware

version D-0146V08.06.XX or later installed.

Voltage Reduction (VR1/OFF/VR2) switch allows Local Voltage Reduction 1 or 2

to be initiated.

Siemens PDS Connector: 10 position Male Pin Connector Half, #421‑00251.

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.
