(2) Remote  Mode Stopping.  To stop the gen- erator set from a remote position, make contact be- tween  the  stop  terminal  and  common  terminal  of the remote control terminal board (fig. 2-9). A soon as the unit stops, break contact. d. Operation of Equipment. (1) General.  When  the  unit  is  operating  and is connected to a load the generator normally oper- ates at the selected voltage, a value that will be in- dicated by the voltmeter. The operator must be ob- servant  of  the  generator  set,  pay  particular attention to any unusual sounds that may indicate malfunction. In case of such an event, stop the unit and report the condition to organizational mainte- nance. (2) Operation. (a) Start the engine (para. 2-2b). (b) Adjust  the  governor  to  achieve  a  reading of 60 Hz on the model MEP-017A unit or a reading of 400 Hz on the model MEP-022A unit (fig. 2-12). (c) Observe  the  voltmeter  (fig.  2-3).  Turn the knob of the voltage adjusting rheostat (fig. 2-3). if necessary, until the proper voltage is attained, as indicated by the voltmeter. TM  5-6115-332-14 P-8-614-14 TO 35C2-3-424-1 NOTE If   voltage   does   not   build   up.   exercising   care   not   to touch    electrical    contacts,    momentarily    depress    the field   flash   switch   (fig.2-5). (d) Position the circuit breaker (fig. 2-3) in the ON position. (e) Again, observe the voltmeter and adjust the voltage adjusting rheostat to attain the proper voltage, if necessary. (f)  Position   the   ammeter   phase   selector switch  (fig.  2-3)  in  each  of  the  three  positions  in turn, and at the same time observe the current indi- cator meter (fig. 2-3). The meter should not give an indication greater than 100% in any phase with any type load. With a straight, resistive load, such as in- candescent lighting, it should not exceed 80% (100% at  1.0  power  factor).  If  the  meter  indicates  a  load greater than these values in any phase, reduce the load.  Balance  the  load  on  each  of  the  three  phases,  if possible. (g)  Position  the  voltage  selector  switch (fig. 2-3) in each of the six positions, in turn, and ob- tain a voltmeter reading in each of the six positions. NOTE If   the   voltage   drops   under   load,   the   voltage   regu- lator   is   defective.   Report   the   condition   to   or ganizational    maintenance. Section II. OPERATION  OF  AUXILIARY  EQUIPMENT 2-3.  General A blowtorch  that  is  specifically  designed  for  pre- heating the engine is available for issue. It is nor- mally  to  be  used  at  temperatures  below  -25°F (-31.7°C). Refer to paragraph 2-4 for the operating instructions  and  special  precautions  that  apply  to the use of the blowtorch. 2-4.  Blowtorch a.  Description.   The  blowtorch  is  a  multifuel pump-type torch. It has a fuel capacity of one pint. hold  the  flame  in any  one  spot.  Keep heat   and   flame   away   from   non- metallic  parts.  When  cranking  with the starter, do not crank longer than 8 seconds.  Allow  2  minutes  for  the starter  to  cool,  between  cranking periods. b. Operation and Service. For blowtorch oper- ation and service instructions, refer to figure 2-11. It is used to preheat the engine crankcase, cylinder heads, intake manifold, and aid intake preheater. CAUTION When  using  a  torch  for  preheating, play the flame back and forth. Do not NOTE Play   the   flame   back   and   forth   over   the   cylinder heads    and    intake    manifold,    briefly,    then    play    the flame   over   the   air   intake   preheater   for   1   or   2 minutes.    While    still    applying    heat,    crank    the    en- gine.   If   the   engine   fails   to   start   after   several   tries, apply   heat   to    the   drive   end   of   the   magnets   briefly and   then   to   the   exposed   surfaces   of   the   oil   pan   for about    5    minutes.    Extended    cranking    with    the    choke “closed’”   will   cause   flooding   of   the   engine.   If   this happens,   remove,   dry   and   reinstall   the   spark   plugs.
