Remote Voltage Control

Usage:

Partial View Of Regulator
(1) Potentiometer. (2) Jumper. (3) Regulator.

Generator output voltage level can be controlled from a remote location. This is done by connecting potentiometer (1) between terminals 6 and 7 on voltage regulator (3).

Remove jumper (2) between terminals 4 and 7 for remote voltage level control.

For acceptable voltage control, the remote mounted potentiometer must be 10k ohms ±5% with three turns and a dielectric strength of 1000 VAC minimum.

The terminals of the remote mounted potentiometer are fragile. The wiring connected to remote mounted potentiometer (1) should not have a diameter larger than 18 gauge. Larger diameter wire is not recommended. The wire should be 600 volt class with a 90°C (194°F) insulation.

NOTE: Either jumper (2) or remote potentiometer (1) is required for regulator operation. If one or the other is not connected the regulator will go to high voltage.
