The M‑2069 is an adapter panel which, when combined with the M‑2001C or M‑2001D Digital

Tapchanger Control, provides convenient direct replacement for Westinghouse SVC and SVR

controls and Beckwith Electric M‑0067E controls. The M‑2069 can also be used, with the M‑2001

Series Tapchanger Control, as a general purpose LTC transformer control. The M‑2069 permits

changing of the M‑2001 control without adapter panel removal or rewiring.

Interface

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

The second terminal block provides auxiliary functions, including self‑test alarm, user‑programmable

alarm, manual raise/lower, operations counter and ∆VAr 2 disable.

enables tapchanger adjustment from the front panel using the Raise/Lower toggle switch.

RAISE/LOWER: allows local manual Raise and Lower commands to be initiated in Manual mode.
