POLARIZED DISCONNECT SWITCH (JACK PLUG) AND HINGED CONTROL PANEL

The Accu/StatTM 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.

VARI-AMPTMPOSITION INDICATOR

The Vari-AmpTMfeature 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.

REMOTE MOUNTING

OF CONTROL

EQUIPMENT

The Accu/StatTM 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.
