PT-ECU-63 ENGINE CONTROL MODULE
1)
Generator Main Switch must be in the ON position.
2)
Hold Start/Stop Switch for 1 second and release.
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-63 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-63
will terminate the cranking cycle and LED will flash a fault code.
6)
Starter disengages immediately after engine run is verified.
7)
PT-ECU-63 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-63 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, hold the Start/Stop Switch for 1 second and
release.
10)
If a fault occurs turn Generator Main Switch OFF and then ON to reset PT-ECU-63.

NOTE:
The PT-ECU-63 is designed
to operate on 12V DC power. In a low
battery situation the PT-ECU-63 may
not initiate the normal cranking cycle.
To start the generator you can press
and hold the Start/Stop Switch for
approximately 10 seconds or until the
engine starts. Once the engine starts
the PT-ECU-63 will resume normal
operations. If this situation reoccurs,
charge or replace the battery.
