The M‑2174B is a replacement panel which, when combined with the M‑2001

Series Digital Tapchanger Control, provides convenient direct replacement for

Tempo (Moloney) LTC Control Panels. The M‑2174B hardware consists of a

front panel with a hinge on the right side, and mounts into the control cabinet

using the same door mounting hardware which must be saved from the original

panel. The door mounting hardware consists of either a locking handle, or two

thumbscrews, depending on the original panel configuration.

The M‑2174B features a voltmeter testing terminal, circuit breakers for the

motor and for the voltage transformer, a manual RAISE/OFF/AUTO/OFF/LOWER

switch, and a fuse for control motor power.

The M‑2174B also includes the M‑2067B Adapter Panel, which contains a voltage

fuse and two terminal blocks on the rear for external connections,
