To prevent accidents be aware of potential dangers and act safely. Read and follow all safety precautions and instructions. SAVE THESE INSTRUCTIONS.
metal surface away from the battery. To avoid sparks, do not disturb the battery charger connections while the battery is charging. Always turn the battery charger off before disconnecting the battery connections. Ventilate the compartments containing batteries to prevent accumulation of explosive gases. Battery short circuits. Explosion can cause severe injury or death. Short circuits can cause bodily injury and/or equipment damage. Disconnect the battery before generator set installation or maintenance.
Propane (LPG)—Adequate ventilation is mandatory. Because propane is heavier than air, install propane gas detectors low in a room. Inspect the detectors per the manufacturer’s instructions. Natural Gas—Adequate ventilation is mandatory. Because natural gas rises, install natural gas detectors high in a room. Inspect the detectors per the manufacturer’s instructions. Gas fuel leaks. Explosive fuel vapors can cause severe injury or death. Fuel leakage can cause an explosion.
Short circuits. Hazardous voltage/current will cause severe injury or death. Short circuits can cause bodily injury and/or equipment damage. Do not contact electrical connections with tools or jewelry while making adjustments or repairs. Remove all jewelry before servicing the equipment. Engine block heater. Hazardous voltage will cause severe injury or death. The engine block heater can cause electrical shock.

transfer switch. Also see Section 2.7, Model RXT Transfer Switch Operation. The RDC2 controller must be in AUTO mode for automatic transfer switch operation. Automatic Start The RDC2 controller receives utility source voltage sensing data from the Model RXT transfer switch. 1. If the utility source voltage falls below an acceptable level, the controller starts the engine start time delay. 2. If the utility source is not restored before the time delay expires, the generator set starts. 3.
Engine Speed, RPM 2.5.2 3 min. 1 min. Engine Exercise The unloaded full speed exercise runs the generator set at full speed for 20 minutes without transferring the load. To set an unloaded full speed exercise, follow the procedure in Figure 2-3 and select Exercise Mode: Unloaded Full. 1 min. 10 min. Unloaded Full-Speed Exercise 5 min. Full-Speed Diagnostics Cooldown Figure 2-1 Unloaded Exercise Cycle System Diagnostics During the unloaded cycle exercise, the controller monitors the following data.
If the utility power is lost during a loaded exercise, the exercise is ended. The ATS remains in the emergency position and the control goes into the AUTO mode. The generator set continues to run and supply power to the load for the duration of the utility power outage. When Utility power is restored, the ATS will re-transfer to the utility source through normal timing sequences. 2.5.
12. Set the exercise frequency (weekly or every two weeks). Weekly exercises are recommended. 13. Press the down arrow button to step to the Return menu. Press the Select button to return to the main menu. 14. Check that the AUTO LED is lit. The generator set must be in automatic mode for the exercise to run as scheduled.

Note: Do not sandblast, wire brush, scrape, or otherwise service spark plugs in poor condition. Obtain a new plug for best results. 9. Check the spark plug gap before installing any spark plug. See Figure 4-7 and Figure 4-8. Attain a correct gap when the feeler (or wire) passes between the spark plug electrode. It should pass easily but with some resistance or drag; otherwise adjust as necessary. Spark Plug Specifications Spark plug gap 0.76 mm (0.03 in.) Spark plug torque 27 Nm (20 ft. lbs.
Problem/Condition Means of Identification Possible Cause/Solution Gap-bridged spark plug Built-up deposits and gap between electrodes closing. Oil or carbon fouling. Clean and regap the spark plug. Oil-fouled spark plug Wet, black deposits on the insulator shell, bore, and electrodes. Excessive oil entering combustion chamber through worn rings and pistons, excessive clearance between valve guides and stems, or worn or loose bearings. Replace the spark plug.
4.8 Battery Consult the battery manufacturer’s instructions regarding battery care and maintenance. WARNING Sulfuric acid in batteries. Can cause severe injury or death. Wear protective goggles and clothing. Battery acid may cause blindness and burn skin. Battery electrolyte is a diluted sulfuric acid. Battery acid can cause severe injury or death. Battery acid can cause blindness and burn skin. Always wear splashproof safety goggles, rubber gloves, and boots when servicing the battery.
4.8.1 Checking Electrolyte Level Check the electrolyte level of batteries with filler caps monthly. Remove filler caps and verify that electrolyte level reaches bottom of filler holes. Refill as necessary with distilled water. DO NOT add fresh electrolyte. Tighten all filler caps. If water is added during freezing temperatures, run the generator set for 20--30 minutes to mix the electrolyte and water to prevent battery damage from freezing. 4.8.
4.9 Storage Procedure 5. Keep spark plugs in their holes or seal spark plug holes with suitable threaded metal plugs. WARNING 6. Clean the exterior of the generator set and spread a light film of oil or silicon spray over any exposed surfaces that may be subject to rust or corrosion. 7. Seal the air inlet, exhaust pipe, and fuel tank cap with tape. Hot engine and exhaust system. Can cause severe injury or death. 8. Disconnect and remove the battery.
