The manual voltage control is an option. The manual voltage control can be used to control the generator voltage when there is a failure in the generator regulator assembly. The manual voltage control will manually control the current flow to the exciter stator. The manual voltage control panel has a switch (1) and a voltage control potentiometer (2) for the manual operating mode. The switch (1) is used to make the selection between the following positions: AUTO, MAN and OFF.

There is a manual voltage control in case of a regulator failure. The stability adjustment allows the quickest response time to block loading while still maintaining steady state stability. Technical specifications for the VR6 AVR The regulator response is less than 4 milliseconds.

In the AUTO position, the VR6 voltage regulator controls the generator voltage. Acer travelmate 4335 drivers free download.

In the OFF position, the generator output voltage will go to near zero.

In the MAN position, the generator output voltage is controlled by the voltage control potentiometer (2).

Note: The manual voltage control panel must not be installed in a location that is subject to engine vibrations or to outside weather.

Note: Do not rapidly switch the 'Manual Voltage Control' (MVC) from 'Manual' to 'Auto' or from 'Auto' to 'Manual'. The switch must stop or pause at the 'OFF' position momentarily. If the position of the switch is changed too rapidly, then the VR6 will shut down due to the 'Over Excitation' protection function.
