SECTION 9 : TROUBLE SHOOTING 

SYMPTOM 

POSSIBLE CAUSES 

SOLUTIONS 

Voltage does not 

build up 

Engine under speed 

Please refer to generator service manual 

Low residual voltage 

Please refer to section 8. Field Flashing 

B,  C,  F+,  F

-

,  Terminal  connection  not 

properly connected 

Reference from Figure 3 

 Figure 5 

Defective generator 

Please refer to generator service manual 

Blown Fuse 

Over excitation current / incorrect wiring   

Reference from Figure 3 

 Figure 5 

Low output voltage 

A, C, B, C, Terminal incorrect connection 

Reference from Figure 3 

 Figure 5 

Defective VR or not properly connected   

Check connection and VR 

Under frequency 

Please refer to generator service manual 

Incorrect exciter specification 

Please refer to generator service manual 

AVR Incorrect voltage selected 

Please refer to section 4. DIP Switch setting 

Over output voltage 

A,  C,  terminals  not  properly  connected  or 
incorrectly connected 

Reference from Figure 3 

 Figure 6 

AVR Incorrect voltage selected 

Please refer to section 4. DIP Switch setting 

Output voltage 

unstable (Hunting) 

STAB

Stability incorrectly adjusted 

Please refer to section 6. Adjustment 

 

ATTENTION 

1.  AVR can be mounted directly on the engine, genset, switchgear, control panel, or any position that will not 

affect operation. For dimension reference, please see Figure 2. 

2. All voltage readings are to be taken with an average-reading voltmeter Meggers and high-potential test 

equipment must not be used. Use of such equipment could damage the AVR. 

3. Improper  setting  of  under-frequency  protection  could  cause  the  output  voltage  of  the  unit  to  drop  or 

become  unstable  under  with  changes  in  load.  Avoid  making  any  changes  to  the  U/F  setting  unless 
necessary.
