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.
