Information:
Knee Frequency and Underfrequency Selection
Illustration 1 g00695812
The physical differences between the VR3 and the VR3F are minor. The hole for Gain adjustment is eliminated and another terminal is added to the upper row (terminal 10) on the VR3F. All VR3F connections to the generator or external options are identical to the VR3. The additional wiring for the VR3F is shown in the previous diagram. The following information is applicable to both VR3F designs: Self-Excited and Permanent Magnet Excited.
In order to determine the knee frequency, install a jumper from terminal 6 to terminal 10 on the regulator if the generator is operating at 60 Hz. If the generator is operating at 50 Hz, remove the jumper.
In order to determine the underfrequency slope selection, install a jumper from terminal 6 to terminal 8 on the regulator if a 1:1 Volts/Hertz underfrequency slope is desired. remove the jumper If a 2:1 Volts/Hertz underfrequency slope is needed.Typical Permanent Magnet Excited VR3F
