Initial Checks And Adjustments At Installation - 2301 Governor (Load Sharing Only)
Introduction
This section is a guide to be used for first installation of the engine and generator, 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 or a mechanical problem.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. 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

I. Visual Inspection
A. At Engine1. Governor Linkage Checks: a. 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, 0.56 to 0.85 mm (.022 to .033 in.). See Service Procedure K.3. Magnetic Pickup Resistance (approximately 200 ohms).4. EG3P & EG10P Actuator Connector: a. Jumper must be across pins C and D of mating connector (for those actuators that use pin connectors).5. Shielded Wire Checks: a. Only one end to be grounded (to governor chassis).*b. Not in same conduit with high current cables.*Except when overspeed switch is used. B. At Governor1. Check for shielded wire on the governor inputs that follow: T10 & T11 (Paralleling Lines)T14 & T15 (Ramp Switch)T18 & T19 (Magnetic Pickup)T20 & T21 (Jumper or Remote Speed Pot)T22 & T23 (Engine Protection System)T23 & T24 (SPM Synchronizer)T26 & T27 (Droop/Isoch Mode)2. Check for broken or loose terminals at all connections that follow: T1 (Phase A) Potential TransformerT2 (Phase B) Potential TransformerT3 (Phase C) Potential TransformerT4 & T5 (Phase A) Current TransformerT6 & T7 (Phase B) Current TransformerT8 & T9 (Phase C) Current Transformer Dynamic Checks must also be made for terminals T1 thru T9.T10 (+) & T11 (-) Paralleling lines common to all units.T12 (+) & T13 (-) DC Voltage Supply.T14 & T15 Ramp Switch - Close for Rated speed or open for Low Idle speed (jumper for initial start-up).T16 (-) & T17 (+) Actuator terminals:a. Measure resistance (infinity) from T16 to ground and T17 to ground.b. Remove actuator wires from T16 & T17. Measure resistance (30 to 40 ohms) across disconnected wire ends (with actuator still connected).c. Install wires correctly back to terminals when finished.T18 & T19 Magnetic Pickup - Measure resistance (approximately 200 ohms) in wires to and from mag. pickup (with mag. pickup connected).T20 & T21 Speed Trim - Use 100 ohm variable resistor or jumper across terminals.T22 & T23 Minimum Fuel - Keep open unless
