ARMY TM 9-6115-464-12 AIR FORCE TO 35C2-3-445-1 NAVY NAVFAC P-8-624-12 2-7 STOPPING THE GENERATOR SET. a. Normal Stopping. (1) Refer to Figure 2-9 for stopping procedures. (2) Refer to Table 2-2 and perform the AFTER OPERATION checks and services, If acoustic suppression kit is installed, do not allow persaonnel to open or dose exhaust discharge door when unit is hot. Serious burns or personal injury may result. NOTE if acoustic suppression kit is installed, after unit has cooled, close both inlet and discharge doors on roof after operation. b. Stopping by Safety Devices. NOTE if any emergency situation requires continued operation of the generator set, the BATTLE SHORT switch may be used to over-ride any of the safety devices except the over-speed and short circuit devices. The generator set is equipped with safety devices which will automatically stop the engine and simulta- neously open the main load contactor upon the occurrence of engine overheating, loss of engine oil pres- sure, engine over-speeding, generator overvoltage, or no fuel. The occurrence of short circuits, over- loads, generator under voltage, generator under frequency, or reverse power will result in the actuation of a protective device circuit which will automatically open the main load contactor, but will not stop the engine. The actuation of any protective device will result in the illumination of the corresponding indicator light on the fault indicator panel. Actuation ratings for each of the protective devices is given in the tabu- lated data portion of paragraph NO TAG. 2-8 PARALLEL OPERATION OF TACTICAL PRECISE GENERATOR SETS. This paragraph provides load connection and operating instructions for parallel operation of the 50/60 Hz and 400 Hz Tactical Precise Generator Sets. Parallel operating procedures are given for Load Sharing and Load Transfer separately. NOTE Prior to attempting parallel operation, ensure all generator sets have the same frequency and voltage output. 2-9 LOAD CONNECTIONS FOR PARALLEL OPERATION. Lethal voltages are present at the load terminal board of the generator set during operation. Do not attempt to connect or disconnect load leads while the generator set is operating. Do not attempt to connect or disconnect load leads with the generator set shut down and the load connected to another power source, or while the generator set is paralleled to another set which is operating. 2-11
