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.
