TM 1-1510-225-10 8-13 b.  CONDITION  lever  (after  N₁  stabilizes  at or  above  12%  for  5  seconds)  –  LOW IDLE. CAUTION Monitor ITT to avoid a hot start.  If there is a rapid rise in ITT, be prepared to abort the start  before  limits  are  exceeded.    During engine start, the maximum allowable ITT is 1000  °C  for  5  seconds.    If  this  limit  is exceeded,    use    Abort    Start    procedure, Paragraph   8-24,   and    discontinue    start. Record the peak temperature and duration on DA Form 2408-13-1. c.   ITT   and   N₁   –   Monitor.      ITT   1000   °C maximum.  N₁ minimum 61%. d.  Oil pressure – Check (60 psi minimum). e.  IGNITION  AND  ENGINE  START  switch – OFF after 50% N₁. 3.  CONDITION  lever  –  HIGH  IDLE.    Monitor ITT as the condition lever is advanced. 4.  GPU  –  As  required.    Disconnect  if  second engine start is to be a battery start.  Refer to Second Engine Start (Battery Start) procedure, Paragraph 8-23. CAUTION Do   not   turn   on   generators   with   GPU connected. 5.  GEN   switch   (after   GPU   disconnected)   – RESET then ON. NOTE After  starting  the  first  engine  with  a  GPU, the   second   engine   is   normally   started utilizing  a  battery  start.    If  a  GPU  start  is required  or  desired  for  the  second  engine start,  use  the  Second  Engine  Start  (GPU Start) procedure, Paragraph 8-27. Otherwise,    use    Second    Engine    Start (Battery Start) procedure, Paragraph 8-23. 6.  BATTERY CHG annunciator – Monitor. * 8-27.  SECOND ENGINE START (GPU START). 1.  Propeller area – Clear. 2.  Engine – Start. a.  IGNITION  AND  ENGINE  START  switch – ON. IGN ON light illuminated and the associated FUEL PRESS light extinguished. CAUTION If ignition does not occur within 10 seconds after moving condition lever to low idle, initiate Engine Clearing procedure,   Paragraph   8-25.      If   for   any reason  a  starting  attempt  is  discontinued, the    entire    starting    sequence    must    be repeated after allowing the engine to come to a complete stop (1-minute minimum). b.  CONDITION lever (after N₁ RPM stabilizes at or above 12% for 5 seconds) – LOW IDLE. CAUTION Monitor ITT to avoid a hot start.  If there is a rapid rise in ITT, be prepared to abort the start  before  limits  are  exceeded.    During engine start, the maximum allowable ITT is 1000  °C  for  5  seconds.    If  this  limit  is exceeded,    use    Abort    Start    procedure, Paragraph   8-24,   and    discontinue    start. Record the peak temperature and duration on DA Form 2408-13-1. c.   ITT   and   N₁   –   Monitor.      ITT   1000   °C maximum. N₁ minimum 61%. d.  Oil pressure – Check (60 psi minimum). e.  IGNITION  AND  ENGINE  START  switch – OFF after 50% N₁. 3.  Right PROP lever – FEATHER. 4.  GPU – Disconnect. 5.  Right PROP lever – HIGH RPM. 6.  GEN switches – RESET, then ON. 7.  DC volt/loadmeters – Check loads, voltage, and current limiters. 8.  CONDITION levers – As required. 9.  CABIN TEMP MODE – Set. 10.  Inverters – Check. 11.  AC/DC power – Check. a.  Frequency and Volts: (1)  AC frequency - 380 Hz to 420 Hz. (2)  AC voltage – 105 Vac to 120 Vac. (3)  DC voltage – 27.5 Vdc to 29.0 Vdc.
