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

when used with regulators which provide a circuit for this purpose.

Options

SCADA CUTOUT switch allows Local blocking of SCADA commands (for use with

SCADA enabled M-2001C controls). Use of the SCADA Cutout Switch with the

M-2001C, requires a M-2001C Control with firmware version D-0146V08.01.22

or later installed.
