① Hold the MSES in an ENABLE position until the selected USI indicator energizes. The switch returns to the center position when released. This sets the PU networking address and enables the control and monitoring.
② No more than one of each indicator can be on for multi-PU operations. The light on should match USS position. The USI light will de-energize after the SMS has been in OFF for 3 seconds.
③ With the SMS in AUTO any generator started, manually or automatically, will automatically parallel to the bus. To prevent the generator from paralleling to the bus put the generator’s breaker in the Pull-To-Lock position.

u. At D-unit, observe Generator 1 automatically parallels to the system bus.
v. At D-unit, observe Generator 2 automatically parallels to the system bus.
w. Observe that each generator assumes 25KW when it parallels to the system bus.
x. From the ORT, set the desired load for all generators running. The load is set on a per generator basis.
y. Ensure generators have assumed load. After the desired load has been stabilized, proceed with the following if necessary:
z. Observe the KW, PF and KVAR of each generator at the LCP.
Note: If adjustment is needed for KVAR balance, start with the generator that is the furthest from the average KVAR (either too low or too high). Make minor adjustments of the Voltage Adjust Rheostat (VAR) until the KVAR sharing between generators are within +/– 10% of the average plant KVAR load. This adjustment will typically be required only once during initial power plant setup and is intended to compensate for meter variations among generators.
CAUTION
Improper adjustment of the VAR can cause a reverse KVAR shutdown of a generator.
NOTE: The automatic economizing feature is disabled while a generator is operating in Utility Parallel mode.
5.8.5 PLANT OPERATIONS
Refer to Chapter 5.9 for specific operating procedures.
The power plant must be in Auto Mode to be operated remotely or to adjust the load on the generators.
5.8.6 POWER PLANT TEARDOWN
5.8.6.1 SHUT DOWN GENERATORS
a. Unload all generators by opening all Tie breakers. This must be done locally from the LCP or ORT.
b. Open both generator breakers using the respective BCS switches.
c. Place both generators in cooldown by placing both ECS switches in STOP/COOLDOWN.
d. Allow all engines to complete cooldown and shut down (5 minutes).
e. Place all ECS switches in OFF/RESET.
f. Pull out the DC Control Power breaker on the PU.
5.8.6.2 DISCONNECT CABLES
NEVER REMOVE POWER CABLES BY HAND, USE HOT STICK AND HIGH VOLTAGE GLOVES. NEVER TOUCH A HIGH VOLTAGE LEAD OR TERMINAL UNTIL IT HAS BEEN DISCHARGED TO GROUND. FAILURE TO OBSERVE THE WARNING MAY RESULT IN DEATH BY ELECTROCUTION.
WARNING
USA TM 9-6115-484-14 DRS RADIAN CTM 01646.1R0253/1R0254 CAUTION
ALLOW ALL OPERATING ENGINES TO SHUT DOWN AND COOL DOWN COMPLETELY.
a. Disconnect the (A)(B) communication cables from between the PUs, Reinstall the communications cable receptacle covers, and store inside the PUs (one per unit).
b. Disconnect the ORT cable and store it in the ORT case.
c. Close and latch the ORT port on the PU.
d. Disconnect all load cables used in operation of the PUs.
5.8.6.3 DISCONNECT FUEL LINES
a. Turn all fuel system valves to the off position.
b. Disconnect the fuel hose from the PU fuel connection and the fuel supply.
c. Drain any fuel from the hoses into an auxiliary fuel supply and store the hoses.
5.8.6.4 DISCONNECT GROUNDING
a. Remove ground connections from the PU and store with the ground rod.
b. Disconnect the parking stations from the ground grid.
c. Remove the parking stations from their operating positions and reinstall them in their transportation locations on the inside of the PU rear side access doors.
5.8.6.5 PREPARE PU FOR TRANSPORTATION a. Reinstall the four radiator splashguards (PU-810B only).
b. Verify DC Control power is off.
c. Close and lock the LCP access doors.
d. Close and lock all PU side doors.
5.8.6.6 FUEL, OIL, AND COOLANT DRAINAGE
The Power Unit may be safely shipped with oil, fuel, and coolant at maximum capacities or less. Draining fluids is not required unless federal, state, or local regulations prohibit shipment with fluids present. Refer to Section 14.3.1.1, Section 13.4.5.5 and Section 6.5.3 for procedures for draining the oil, coolant and fuel liquids respectively.
