ADVR-16-400HZ
SECTION 7 : TROUBLE SHOOTING
SYMPTOM
POSSIBLE CAUSES
SOLUTIONS
Voltage does not
build up
Residual voltage below 5 Vac
Reference from section 6. Field Flashing
F+, F- polarity reversed
F+ and F- reverse the connection
F+, F-, P1, P2, VS1, VS2 not connected Reference from Figure 4 and 5 connection
Burnt fuse
Change fuse 16A 500V
Ext. Switch (Breaker) not turned on
Switch on (ON)
Engine RPM under speed
Increase engine speed / frequency above 25 Hz
Low output voltage
Poor adjustment is made
Read start procedure carefully and adjust again
U/F protection activated
Increase generator speed
U/F activated / Incorrect voltage selection
Read user’s manual to select correct voltage
Over output voltage
Poor adjustment is made
Read start procedure carefully and adjust again
Incorrect voltage selection
Read user’s manual to select correct voltage
Output voltage
unstable (Hunting)
Poor adjustment is made
Read start procedure carefully and adjust again
Field voltage requirement lower the
rang of regulator
Connect appropriate resistors in series to
increase total impedance
