Operation Manual

PT-ECU-64 ENGINE CONTROL MODULE
1) Generator Main Switch must be in the ON position.
2) Toggle the Start/Stop Switch to the START position.
3) Glow Plugs will preheat for 8 seconds. LED flashes slowly.
4) Preheating will cease during engine cranking cycle. LED continues flashing.
5) Engine begins an 8 seconds crank cycle, After 4 seconds of cranking the PT-ECU-64 will check for an
AC signal from the generator. If an AC signal is verified the engine will start and the LED will remain
ON during the normal run operation. If the AC signal is not verified the PT-ECU-64 will terminate the
cranking cycle and LED will flash a fault code.
6) Starter disengages immediately after engine run is verified.
7) PT-ECU-64 deactivates the Low Oil Pressure and High Water Temperature Switches for 6
seconds, this will assure oil pressure build-up time. If oil pressure does not build-up the engine will
immediately shut down and go into a fault mode. Likewise for a high temperature situation.
8) If engine will not start on the first attempt the PT-ECU-64 will initiate the start cycle 2 more times
before going into a fault mode. Glow Plugs will preheat for 8 seconds per attempt. Engine will crank
for 8 seconds per attempt.
9) To shut down the engine under normal operations, press the Start/Stop Switch to the STOP position.
10) If a fault occurs turn Generator Main Switch OFF and then ON to reset PT-ECU-64.
