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.

Interface

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

of the rear panel of the M‑2280B.

Additional connections may be made to two terminal blocks located on

the printed circuit board of the adapter panel. These terminal blocks

provide 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

located 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.

Adapts M‑2001 Series Digital Tapchanger Control to Replace McGraw‑Edison

550 BHS LTC Transformer Controls

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

mounting screws and 24‑pin connector

• Provides direct mechanical replacement of the existing control using the

same two hinge pins

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

Tapchanger Control is removed

The M‑2354C is an adapter panel which, when combined with the M‑2001

Series Digital Tapchanger Control, provides convenient direct replacement

of McGraw‑Edison 550 BHS LTC transformer controls. The M‑2354C consists

of a front panel, and mounts into the control cabinet. The hinge hardware,

knob, and the mounting hardware must be saved from the original control.

Interface

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

fifteen‑position terminal block to the two terminal blocks on the existing

control cabinet. An additional terminal block provides access to aux iliary

functions, including self‑test alarm, user‑programmable alarm, auto disable

and manual raise/lower. An auxiliary current transformer is supplied to

convert the 5 A load current into the 0.2 A used by the control.
