To  start  after  engine  shutdown  caused  by  high  water temperature,  low  oil  pressure  or  overspeed,  turn  switch to STOP position and correct fault.  Then move switch to OFF/RESET   position.      Engine   can   now   be   started   in MANUAL  or  AUTO  position.    For  more  information  on the   operation   of   this   switch,   make   reference   to   the AUTOMATIC START/STOP SYSTEM.

ACV Alternating Current Voltmeter AC  voltmeter  (ACV)  shows  the  potential  differential (voltage)   between   phase   T1-T2,   T2-T3   or   T3-T1   at position  1,  2  or  3  respectively.    Make  reference  to  the ALTERNATING CURRENT AMMETER. DCA Direct Current Ammeter DC  Ammeter  (DCA)  is  used  when-the  ammeter  is ordered.  This ammeter shows the amount of DC current in   amperes,   that   flows   in   the   alternator   circuit   (if   so equipped). FM Frequency Meter Frequency  meter  (FM)  shows  the  hertz  (cycles  per second) of the electricity made when the generator set is in   operation.      There   is   a   direct   relation   between   the frequency of the electricity and the rpm of the generator set; see formula. frequency (hertz) = number of poles x rpm 120 GS Governor Switch Governor  switch  (GS)  is  used  when  the  engine  is equipped  with  a  remote  control  synchronizing  motor  for the   governor.      Engine   speed   is   controlled   with   this switch. HS Heat Switch Heat  switch  (HS)  is  when  the  engine  is  equipped with glow plugs.  This switch is used to operate the glow plugs for cold weather starting. OPG Oil Pressure Gauge Oil  pressure  gauge  (OPG)  shows  the  pressure,  in psi,   of   engine   lubrication   oil.      When   pressure   switch (PSW) is closed, oil pressure gauge (OPG) is connected across  battery  voltage.    There  is  a  relation  between  the current  flow  in  this  circuit  and  the  engine  oil  pressure read on oil pressure gauge (OPG).  Oil pressure sender (OP) controls the current flow by a change in resistance according to the change in engine oil pressure. PAM Prealarm Module Make reference to ATTACHMENTS. PL1, 2 Panel Lamps Light  for  the  control  panel  is  given  by  panel  lamps (PL1  and  PL2).    These  lamps  are  controlled  by  panel light switch (PLS). VLR Voltage Level Rheostat Voltage   level   rheostat   (VLR)   takes   the   place   of voltage  level  rheostat  (R2)  on  the  generator  regulator assembly.    It  is  used  to  adjust  the  voltage  output  of  the generator. NOTE: Make reference to OPERATION OF GENERATOR:   REGULATOR      ADJUSTMENT.      On generators    equipped    with    a    generator    mounted control   panel,   the   yellow   wire   from   voltage   level rheostat (R2) to terminal (7) on the regulator terminal strip is disconnected at terminal (7). 241
