HSB Test
SPEED SETTING NO LOAD
Do NOT move forward until the HSB generator AC output voltage
and frequency are correct and within the stated limits.
1. If the no-load voltage is correct but no-load frequency is
incorrect, the engine governed speed requires adjustment.
1a. Engine speed is normally set to 3750 RPM (62.5 HZ) high
speed no load (HSNL)
1b. Set engine speed with no electrical load on the generator
1c. Use long needle nose pliers, or a long screw driver, to
bend the spring anchor on the fixed speed controls.
i. To increase engine speed HSNL bend the spring
anchor tang on the fixed speed controls away from the
governor lever to increase spring tension.
ii. To decrease engine speed HSNL bend the spring
anchor tang on the fixed speed controls toward the
governor lever to decrease spring tension.
Bend spring anchor tang to adjust engine speed
DANGER
Proceed with caution. Once the Utility Power is turned ON, the
ATS is now electrically hot. The feeder lines and terminals are
now live.
Contact with these connections will result in extremely
hazardous and possibly fatal electrical shock. Use the correct
procedures as described in national electrical codes.
WARNING
The manufacturer recommends that a licensed electrician or
an individual with complete knowledge of electricity perform
these procedures.
