and current under load and varies the exciter field either up or  down  to  keep  the  generator  field  at  such  a  value  as  to maintain  constant  alternator  output  voltage.  The  regulated voltage   setting   can   be   varied   using   the   voltage   adjust rheostat  (R1). An  ac  receptacle  (J14)  is  connected  through  a  protective circuit breaker (CB3) to provide 120 VAC. Outputs  from  the  voltage  regulator  (A2)  transformed  by transforms  (T1  and  T2)  to  a  value  suitable  for  input  to frequency transducer (A3) which energizes frequency meter (M3). 1-10.  TABULATED  DATA.

OPERATING  INSTRUCTIONS Hot refueling of generators while they are oper- ating  poses  a  safety  hazard  and  should  not  be attempted. Hot engine surfaces and sparks pro- duced  from  the  engine  and  generator  circuitry are possible sources of ignition. Severe injury or death  to  personnel  and  damage  to  the  equip- ment may result. Ground set to avoid shock hazard. BEFORE STARTING SET NOTE: Push in DC CONTROL CIRCUIT BREAKER.  Pull  manual  governor  control throttle all the way out and then push back in approximately halfway. 1. Fill  crankcase  (do  not  overfill)  and  fuel tank. Ensure that vent cap on underside of the  fuel  filler  cap  is  open  before  starting generator. 2.  Set  batteries  are  negative  ground. STARTING SET 1. 2. 3. 4. 5. 6. Move “MASTER SWITCH” to “PRIME & RUN” position to allow fuel to prime set. Move “MASTER SWITCH” “PREHEAT”   position   and   hold   for   (1) minute. NOTE: Preheat is not required when engine is  hot. Move  “MASTER  SWITCH”  to  “START” position and hold until engine fires continu- ously.  If  engine  does  not  start  within  15 seconds repeat steps 1 and 2. “MASTER   SWITCH”   will   return   to “PRIME & RUN” position when released. If running from auxiliary fuel source, move “MASTER SWITCH” to “PRIME & RUN AUX FUEL” position. After   warm   up.   Check   frequency   and voltage  and  adjust  if  necessary. Move  “AC  CIRCUIT  BREAKER”  to  “ON” position. STOPPING SET 1.   Move “AC   CIRCUIT   BREAKER”   to “OFF” position. 2.   Move   “MASTER   SWITCH”   to   “OFF” position. INSP  STAMP: 3.  For  emergency  stop  pull  “DC  CONTROL CIRCUIT  BREAKER.” Change 9 1   -  5
