EA06

 

SECTION 1 : SUMMARY 

EA06 is equipped with 3 separate sensing inputs (1-2, 
3-4, 5-6 terminals R.S.T phase), which can survey from 
single  up  to  three  phase  voltages  and  check  the 
average voltage from Y, YY or 

 wiring accordingly to 

the generator requirement or user preference. 
 
 

The AVR is equipped with adjustable under frequency 
protection  and  over  voltage  protection  to  prevent 
generator from overloading and over excitation. 
 
The  3  LED  each  represents  (Green)  normal  operation, 
(Red) under frequency and (Yellow) over excitation. 
 
The  built  in  EMS  filter  helps  to  prevent  possible 
interference from the AVR to the generator.

ATTENTION 

1.  AVR  can  be  mounted  directly  on  the  engine,  genset, 

switchgear,  control  panel,  or  any  position  that  will  not 
affects operation. For  dimension  reference, please  see 
Figure 1. 

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.  Secure  all  wiring  connection.  Do  not  install  AVR  at  a 

place with high vibrations to prevent loose connections. 
For safety do not touch the heat sink while in operation. 

4.  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.
