Interface

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

panel of the M‑2278. Additional connections may be made to two terminal blocks

located on the printed circuit board of the adapter panel.

These terminal blocks 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.

NEUTRAL LIGHT will light to indicate that the regulator is in the neutral position

for those products equipped with a circuit for this purpose.
