POLARIZED DISCONNECT SWITCH VARI-AMP TM POSITION INDICATOR
(JACK PLUG) AND HINGED
CONTROL PANEL
The Accu/Stat
TM
control panel is hinged and may be re-
moved completely from the regulator control box by
removing the wing nuts on the polarized jack plug and
pulling the jack from its fixed position. This will
automatically de-energize the control. It is not necessary
to bypass or de-energize the regulator to remove the
control.
A spring-loaded shorting bar in the plug automatically
short circuits the current transformer secondary when
the jack is removed.
REMOTE MOUNTING
OF CONTROL
EQUIPMENT
The Accu/Stat
TM
control may be remotely mounted.
Remote cable is available in standard lengths of 18, 25
and 30 feet incorporating oil and moisture resistant,
color-coded conductors.
The Vari-Amp
T M
feature provides a method of operating the
regulator at increased load by decreasing the range of op-
eration. It provides operator flexibility by allowing the range of
regulation to be adjusted in 1¼ percent increments. The
various regulation ranges together with the corresponding
current capacities for standard regulators are listed on the
next page. All that is necessary to adjust the range of
regulation anywhere from ±5 percent to ±10 percent is to
turn the adjusting knobs until the proper range of regulation
is shown on the side of the position indicator. The upper and
lower limits need not be the same.
It is not necessary to remove the regulator from service to
make this adjustment. The switches are, however, in the
motor power circuit so the motor should not be running while
the switches are being set.
