Measure dc voltage across pins A and B of GOVERNOR CONTROL receptacles J18, J19, or J20 (see Figure
2-18). Voltage should be 5.4 to 5 6 V dc If not, proceed as follows:
Open upper cabinet B door.
See Figure 2-6 Adjust LOAD SHARING SENSITIVITY (5) on the load sharing module to obtain a
reading of 5.4 to 5.6 V dc across PARALLEL LINES terminals 10 and 11. These are on the terminal
board across the bottom of the load sharing module
Close upper cabinet B door.
Set BREAKER CONTROL switch S4 (20, Figure 2-2) to TRIP
Operate generator set until engine thermostats open and normal coolant temperatures can be obtained. Add
additional coolant If necessary
Allow generator set to operate at least 5 minutes at no load. Then shut down generator set in accordance with
Leave generator set connected to utility power at all times, if possible. If not possible, set UTILITY
POWER circuit breaker CB125 (5, Figure 2-11) to OFF, operate circuit breaker locking beam (3), and set SET POWER
circuit breaker CB124 (4) to ON.
Leave EMERGENCY LIGHTING switch CB CB2 (17, Figure 2-1) on at all times Emergency lights will
automatically shut off in presence of set or utility power.
(3) Leave generator heaters and engine coolant and oil heaters on at all times The heaters will automatically
shut off when the generator set is running.
SECTION II. MOVEMENT TO A NEW WORK SITE
4-3. DISMANTLING FOR MOVEMENT. Shut down generator set in accordance with Figure 2-15 (single set) or Figure
2-20 (parallel), then proceed as follows
Load Circuit Breaker CB101 and Main Disconnect Switch S120. The generator set Is shipped with main
disconnect switch S120 locked in CLOSED position and the kirk-key interlock key Installed on load circuit breaker
CB101. For shipment purposes, load circuit breaker C8101 Is held In place using integral shipping braces that are
installed as follows ;
Open lower cabinet B door (Figure 4-6) Remove shipping screws (2) Installed on threaded mounts on both
sides of the circuit breaker frame
Loosen mounting screws holding shipping braces (1) Rotate shipping braces 90 degrees upwards and
towards center of compartment
With racking handle (7), turn racking crank (3) counterclockwise until load circuit breaker CB101 (8) frame
is flush against shipping braces (1). Position braces (1) so that mounting holes on load circuit breaker CB101 (8) frame
and braces are exactly aligned. Then tighten screws holding braces against cabinet frame.
Install shipping screws (2) removed from threaded mounts on braces (1) against load circuit breaker
CB101 (8) frame and tighten.
Disconnection of Cables Harnesses and Hoses
Never remove power cables by hand unless generator set Is off and
power cables are not connected to a live voltage source. Never touch a
high-voltage lead or terminal until it has been discharged to ground.
Failure to observe this warning may result in death by electrocution.
