AVR WIRING
AS440 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. VOLTS - Adjust generator output voltage.
Clockwise to increase voltage.
2. LINK: HAND TRIMMER
1-2: NO TRIMMER
NONE: TRIMMER FITTED
Adjust alternator output voltage.
Clockwise to increase voltage by AVR voltage adjustment.
3. STABILITY - To prevent voltage hunting.
Clockwise to increase dampening effect.
4. LINK: POWER: RESPONSE
A-B: > 550kW : Fast
B-C: 100-550kW : Fast
A-C: < 100kW : Fast
B-D: < 100kW : Slow
5. UFRO - Under Frequency Roll Off
Clockwise decreases ‘KNEE’ point.
6. SWITCH - Select alternator frequency for UFRO
SWITCH LEFT: 60Hz
SWITCH RIGHT: 50Hz
7. LED Indicator Light - LED light on in UFRO or O/EXC
condition.
8. DROOP - Adjust alternator droop to 5% at zero power
factor.
Clockwise to increase droop.
9. TRIM - Adjust analog input sensitivity.
Clockwise to increase sensitivity.
10. O/EXC - Adjust over-excitation trip.
Clockwise to increase trip voltage.
11. LINK: SUPPLY
8-Z2: Main stator
None: Auxiliary winding
Select AVR supply source.
