ARMY  TM  9-6115-645-10 AIR  FORCE  TO  35C2-3-444-11 MARINE  CORPS  TM  09244A/09245A-10/1 j. Rotate  the  VOLTAGE adjust  potentio- meter  of  generator set No.    1 until ammeter  (PERCENT RATED  CURRENT)  reads approximately  “O". k. Close the load contactor at the load. NOTE If the REVERSE POWER  indicator of  either generator  set lights, and the AC  Circuit Interrupter relay  opens, open the load contactor at load and de- synchronize  the generator sets. (Repeat  the necessary  steps d through k above.) l. Compare  ammeter (PERCENT RATED CURRENT)  readings  of both generator sets. If readings are not within 10 percent, notify  next  higher level of maintenance. m. Compare  kilowatt- meter  (PERCENT POWER) readings of both generator sets. If readings are not within 10 percent, notify  next  higher level of maintenance. 2-10.4  Removal  from  Parallel Operation. If necessary to move  a  generator set which has been  operating in parallel with another  genera- tor set, shut down  remaining generator  set connected to the load, prior to removing  load cables or ground. Failure to observe this warning  can result in injury or death by electrocution. Prior to removal of generator set from parallel operation,  make sure load does not exceed full load rating of generator  set remaining on the line. Failure to observe this caution  can result in damage to  generator set. a. Position  AC  CIRCUIT INTERRUPTER  switch to OPEN until indicator goes out. b. Return  UNIT-PARALLEL switch to UNIT position. 2-28
