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.
