LTC transformer controls

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.
