WARNING
This Automatic Voltage Regulator is not
equipped with loss-Sensing Protection function /
Over
Excitation
Protection.
An
additional
Over-Voltage Protection device for load may be
required to avoid possible damage to the
equipment or severe personal injury or death.
ATTENTION
1. AVR installation should only be performed by
a qualified technician.
2. Install AVR inside the generator control panel
to avoid high temperature, moisture, and
location where AVR cannot be easily reached.
3. AVR heat sink may reach a high temperature
(above 60
˚C) when AVR is powered, do not
touch or ground AVR heat sink.
4. Make sure you have read and understand the
contents of the instruction manual prior to
installation. Incorrect wiring connection may
result in irreversible damage to the product
and other equipments.
SECTION 6 : TROUBLE SHOOTING
SYMPTOM
POSSIBLE CAUSES
SOLUTIONS
Voltage does not
build up
Residual voltage below 5
Vac
Field flash is required
Incorrect wiring
Check wiring diagram for proper connection
Engine under speed
Increase engine speed to above 25 Hz
Carbon brushes were worn out
Replace with new carbon brushes
Low output voltage
Voltage set point is not properly adjusted
Adjust VOLT POT clockwise to reach
desired voltage
External voltage adjusted too low
Turn the external VR to reach desired
voltage
Under Frequency Protection is activated
Refer to Section 4
Frequency selection and
knee point adjustment
Over output voltage
Voltage set point is not properly adjusted
Adjust VOLT POT anti-clockwise to reach
rated voltage
Output voltage
unstable (Hunting)
Stability range is not set properly
Refer to Section 2 Adjustment
Field voltage or field resistance is too low
Connect suitable resistor in series to
increase total resistance
