VOLTAGE REGULATOR WIRING
AS480AutomaticVoltageRegulator
The following is a list of connections on the AVR. These have been
factory set and other than voltage adjustment, should never be
changed.
1.GeneratorACsensingconnection(6,7,&8)
 FieldvoltageDC(F1&F2)
2. Voltage adjustment
3. External voltage treatment rheostat.
No external rheostat - link 1 & 2
With external rheostat - 1 & 2 unlinked, connect external rheostat
leads to 1 & 2
4. AVR input selection
 Highvoltage208/240/277-nolinkbetween3&4
Low voltage 120 - link 3 & 4
5. Under Frequency Roll Off adjustment
6. Under Frequency Roll Off indication light
7. Frequency selection:
 50Hzoperation-linkCto50
 60Hzoperation-linkCto60
8.Stabilitycontrol
