2°7 ENGINE GOVERNORADJUSTMENT
If both AC l_-equeney and voltage are eorrespondtagly
high or low, adjust tile engine governor as follows:
2.7,1
15 KW UMTS
1. Loosen governor clamp bolt (See Figure 2.3).

2. Completely remove the idle spring.
3.
With governor arm at wide open throttle position,
rotate governor shaft ikflly clockwise. Tighten
clamp bolt to 84 taeh-pounds.
4. Start unit and apply frill load. Use full load speed
adjust screw {Figure 2.4) to adjust frequency to
58 Hz.
5. Remove load, stop engtae, loosen the idle adjust
screw and reconnect the idle sprtag.
(3. Push the governor arm to the closed throttle posi-
tion. Make sure the idle spring does not stretch at
all.
7. Restart the unit.
8. Slowly turn the idle adjust screw to adjust the no-
load idle fi-equeney to 63-63.5 Hz.
9. The governor is now set.

2.8 VOLTAGEREGULATOR
With the Irequeney between 62-63.5 Hertz, slowly
turn the slotted potentiometer (Figure 2.5) until line
voltage reads 244-252 volts.
NOTE:
Remove the access panel on top of the control
panel to adjust the voltage regulator.

NOTE:
The voltage reg_ator is housed above the generator's
control panel. The regulator maintains a voltage in
direct proportion to frequency. For example, at 62
Hertz, line-to-neutral voltage will be 124 volts.

BREAK4N PROCEDURE
Once the unit has been tastalfed and all electrical
cheeks have been made, it is strongly recommended
that the followtag "Break-ta Procedure" be completed
to ensure correct generator operation ta the future.
1. Set the generator's AUTO/OFF/MANUAL switch to
AUTO.
2. Turn OFF the utility power supply to the transfer
switch ustag the means provided (such as a utility
mata ltae circuit breaker).
3. The unit will start, and the transfer switch will
transfer to standby.
4. Ustag the transfer swifeifs built-ta emergency
load center, mrn on circuits to load the generator
to approximately 25% rated load and run the unit
%r one hour.
5. Run the unit for one hour at 50% rated load.
6. Run the unit for one hour at 75% rated load.
7. Run the unit for one hour at 100% rated load.
8. _[_lrn ON the utility power supply to the transfer
switch, which will allow the transfer switch to
transfer back to utility powen The unit will con-
tinue to run for one mtaute and then shut down.
