STAB Stability Adjustment
Correct
stability
adjustment
must
be
conducted while the generator is operating
without load. First adjust this STAB (POT)
anti-clockwise until the voltage becomes
unstable, and then slightly adjust it clockwise
(about 1/5 turn). When the voltage just
reaches the critical point (knee point) of
stabilization, where the voltage is stable yet
very close to becoming unstable.
U/F LAMP
Lights up when the generator is in U/F (Under
Frequency Protection)
Select frequency 50 or 60Hz according to the
generator in use(refer to section 4)
U/F Under Frequency
Protection Adjustment When generator speed
falls below the knee point, the under frequency
protection circuit will activate and the voltage
begin to decrease in linear descend.
