 The
M-2279C is an adapter panel which, when combined with the M-2001
Series Digital Tapchanger Control, provides convenient direct replacement
for the following Pennsylvania Transformer and McGraw- Edison LTC transformer
and regulator controls manufactured from 1963–1978: 550, 550A, 550B, 550C,
396B, 494B, 496B, 995 and 996.
- Connects easily to the M-2001 Series Digital Tapchanger Control using
mounting screws and 24-pin connector
- Provides direct mechanical replacement of the old LTC transformer
or regulator control using the same four mounting studs, front door
braceand locking knob
- Provides built-in CT shorting protection when the M-2001 Series Digital
Tapchanger Control is removed
Interface
External connections are made at two terminal blocks located on the rear
panel of the M-2279C, and at two terminal blocks located on the printed
circuit board. These terminal blocks provide access to auxiliary functions,
including self-test alarm, user-programmable alarm, auto disable and manual
raise/lower. A fifth terminal block provides for the addition of the M-0329B
LTC Backup Control. The four mounting studs, front door brace and the
front door locking knob must be saved from the existing control cabinet.
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 regulators equipped with a circuit for this purpose.
