Initial Checks & Adjustments At Installation
Introduction
This section is a guide to be used for first installation of the engine or when a replacement of any of the equipment has been made. Too often the equipment is damaged or destroyed before it ever has a chance to be used because of incorrect wiring, lead shorts, wrong polarity, a mechanical problem, or overvoltage.The information that follows contains a basic, step by step checklist to be followed. Before any supply power is applied, all wiring and settings are verified to be correct, as well as the correct voltage level. Then the governor is energized and the components are checked out to see if they function correctly. Finally the engine is started, and the complete system is checked and adjusted dynamically.The correct use of these initial checks will eliminate most of the early failures that can occur.Static Checks
Visual Inspection
At Engine
1. Governor linkage checks: a. Linkage moves freely, not binding.b. Correct thread engagement of rod ends.c. Full travel available to Fuel Off position.d. Full travel available to Fuel On position.2. Magnetic pickup to flywheel ring gear tooth clearance ... 0.5 to 0.8 mm (.02 to .03 in)3. Magnetic pickup resistance ... approximately 200 ohms4. Shielded wire checks: a. Only governor end to be connected to terminals indicated on Governor Connection Diagram.b. Not in same conduit with high current cables.Power Supply Check
It is recommended to use a battery with a charger (60A hour battery rating or larger), or a separate DC power supply (8A or larger).The following tests are performed to verify that the power supply is in the correct voltage range, is clean (no alternating current), and is of sufficient amperage (little or no voltage drop).
KG30 Governor Control Unit
(1) 14 Pin receptacle. (2) 2 Pin receptacle (magnetic pickup). (3) 10 Pin receptacle (accessory connection).1. Before turning on the power to the KG30 governor control unit, disconnect the large 14 pin plug from the 14 pin receptacle (1) and connect a multimeter in the DC volts mode to this plug in the wiring harness at pin E (+) and pin F (-). Turn on power to the KG30 governor control unit. The voltage must be 20 to 35V DC (preferably 24V DC). With the multimeter still connected, put the multimeter in AC volts mode. If it reads more than approximately 1V AC, the voltage supply must be inspected to find the source of the excessive AC voltage. Do not connect the plug to the controller if any excessive AC voltage is present. The governor system will not function properly, and it can be damaged.2. Once the voltage is verified to be clean and in the correct range from the previous test, connect the main 14 pin connector to the KG30 governor control unit and disconnect the magnetic speed pickup connector (2) and accessory connector (3).
