TM 5-6115-593-12 TO 35C2-3-463-1 CHAPTER 2 OPERATING INSTRUCTIONS Section I. OPERATING PROCEDURES 2-1. GENERAL. a. Instructions  in  this  section  are  provided  for information  and  guidance  for  personnel  responsible  for operation of the generator set. b. The   operator   must   know   how   to   perform every operation of which the generator set is capable of performing.    This  section  describes  and  illustrates  the various controls and instruments required to operate the generator set, and step-by-step instructions with supporting  illustrations  for  operating  the  generator  set under normal conditions. 2-2. The purpose and location of generator set controls and instruments are described in tables 2-1 through 2-4 and illustrated in figures 2-1 through 2-4. 2-3. NORMAL OPERATING CONDITIONS WITHOUT HOUSING KIT INSTALLED.  The following paragraphs provide step-by-step procedures with supporting illustrations. Preparation for starting (figure 2-5), starting instructions  (figure  2-6),  stopping  instructions  (figure  2- 7), and operating instructions for a single generator unit (figure 2-8).  See par. 2-9 for operation with housing kit installed. 2-4. STARTING. a. Preparation  for  Starting.  Instructions  to  be followed  when  preparing  to  start  the  engine  generator set  are  shown  in  figure  2-5.    Preventive  maintenance procedures    to    be    performed    before    operation    are provided in table 3-2. b. Starting.    After  performing  the  preparation for starting procedure, start the engine generator set as shown in figure 2-6. If the engine will not start, or if any other    abnormality    is    observed,    notify    higher    level maintenance personnel. 2-5. STOPPING. a. Normal Stopping. (See figure 2-7). Preventive   maintenance   procedures   to   be   performed after equipment operation are provided in table 3-2. b. Stopping by Safety Devices.  The generator set is equipped with safety device electrical circuits that automatically  stop  the  engine  and  simultaneously  open the  main  AC  circuit  breaker  in  the  case  of:    (1)  high coolant   temperature,   (2)   low   oil   pressure,   (3)   engine overspeed,  (4)  overvoltage,  (5)  no  fuel,  or  (6)  high  oil temperature.  A short circuit, overload, or reverse power protective   relay   will   automatically   open   the   main   AC circuit breaker but will not stop the engine. Undervoltage relay  protective  circuit  will  similarly  open  the  main  AC circuit   breaker   but   will   also   not   stop   the   engine.      A specific  fault  indicator  (five  for  the  engine  and  five  for the  generator,  figure  2-2)  will  light  when  any  of  these abnormal conditions occur.  Once the generator set has been  stopped  due  to  the  action  of  one  of  these  safety devices,   the   problem   must   be   corrected   before   the generator set is placed back in operation. c. Emergency Stopping.  To stop the generator set   in   an   emergency,   open   the   24V   DC   CONTROL CIRCUIT    BREAKER    (figure    2-7)    or    EMERGENCY SHUT DOWN switch (figure 2-3). 2-6. OPERATION OF EQUIPMENT. a. Remote Control Module Operation. See par. 2-10. b. Automatic  Control  Module  Operation.    See par.  2-11. 2-1
