Operation Manual

Starting and Stopping the PT-3000

CHECK BEFORE OPERATING THE ENGINE

• If the engine is malfunctioning DO NOT operate until repairs

are made.

• Be sure cover, guards and shields are in place before operating

the engine. Replace any that are damaged or missing.

• Check to see that the area around the engine is clear of foreign

objects before starting.

• DO NOT allow children or animals to approach the APU

while in operation.

• DO NOT start the engine by shorting across starter terminals.

Engine starting controls

1) PT-3000 Main switch (located on the internal control panel on the APU) must

Be in ON position.

NOTE: This switch should be in the ON position except when performing

maintenance or to prevent starting for any reason.

2) Toggle the driver control panel switch to the ON position.

3) Glow plugs will preheat for 8 seconds. LED light flashes slowly.

4) Preheating will cease during engine cranking cycle. LED light continues flashing.

5) Engine begins an 8 second 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 light 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 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, push the driver control box

switch to the STOP position.

10) If a fault occurs during the normal operation of the PT-3000 the LED on the

driver control box will repeat a flashing code. This code will help troubleshoot the

problem. Count the flashes to determine the problem and refer to the service

manual for corrective procedures. The fault codes are as follows

LED Flashes 1 Time: Failure to Start

LED Flashes 2 Times: High Water Temperature

LED Flashes 3 Times: Low oil Pressure

LED Flashes 4 Times: No AC signal
