Anleitung Zusammenfassung
Check oil level (see Section 4-2). Engine will not start if oil pressure is too low. Reset circuit breaker CB10 (see Section 7-8). Check coolant level and fan belt (see Section 4-2 and engine manual). Engine will not start if engine temperature is too high. Check and refill crankcase with proper viscosity oil for operating temperature, if necessary (see engine manual). Have Factory Authorized Service Agent check low oil pressure switch S2 and engine coolant temperature switch S3. Engine does not stop. Stop engine by pushing down engine stop lever (see Section 4-2) or closing fuel valve (see Section 4-2). After stopping engine, adjust fuel solenoid linkage (see engine manual). Engine stopped during normal operation. Check fuel level (see Section 4-2). Open fuel valve (see Section 4-2). Check oil level (see Section 4-2). Engine stops if oil pressure is too low. Check coolant level and fan belt (see Section 4-2 and engine manual). Engine stops if engine temperature is too high. Bleed air from fuel system according to engine manual. Have Factory Authorized Service Agent check low oil pressure switch S2 and engine coolant temperature switch S3. Battery discharges between uses. Clean top of battery with baking soda and water solution; rinse with clear water. Periodically recharge battery (approximately every 3 months). Replace battery. Check voltage regulator according to engine manual. OM-492 Page 35 Trouble Remedy Engine does not go to low (idle) speed with Engine Control switch in Run/Idle position. Be sure Engine Control switch S1 is in Run/Idle position. Remove all weld and auxiliary power loads. Turn off remote device connected to Remote 14 receptacle RC5 (see Section 4-8). Check for obstructed movement of throttle solenoid linkage. Have Factory Authorized Service Agent check voltage regulator board PC8 and current transformer CT1. Reset circuit breaker CB9 (see Section 7-8). Engine does not go to high (run) speed when auxiliary power or large weld load is applied with Engine Control switch in Run/Idle position. Place Engine Control switch in the Run position. Have Factory Authorized Service Agent check unit. Engine uses oil during run-in period; wetstacking occurs. Dry engine (see Section 9 and engine manual). Coolant recovery tank continuously overflows. Bleed air from radiator, and replace lost coolant (see Section 4-3).

Circuit Diagram For Welding Generator OM-492 Page 39 200 955 SECTION 9 – RUN-IN PROCEDURE run_in4 6/99 9-1. Wetstacking 1 Welding Generator Run diesel engines near rated output during run-in period to properly seat piston rings and prevent wets- tacking. See nameplate or rating label to find rated output. Do not idle engine longer than necessary. Piston rings seat faster if engine runs at weld/ power rpm, and the welding generator is kept loaded during run-in. 2 Engine Exhaust Pipe Wetstacking is unburned fuel and oil in the exhaust pipe and occurs during run-in if the engine is run too long at light load or idle rpm. If exhaust pipe is coated with a wet, black, tar-like substance, dry the engine using one of the following run-in procedures. See the engine manual for additional engine run-in information. 1 2 OM-492 Page 40 9-2. Run-In Procedure Using Load Bank S-0683 Stop engine. Do not touch hot exhaust pipe, engine parts, or load bank/grid. Keep exhaust and pipe away from flammables. 1 Load Bank Turn all load bank switches Off. If needed, connect load bank to 115 volts ac wall receptacle or generator auxiliary power receptacle. 2 Welding Generator 3 Weld Cables Connect load bank to generator weld output terminals using proper size weld cables with correct connectors. Observe correct polarity. Start engine and run for several minutes. Set load bank switches and then adjust generator V/A control so load equals 225 amps at 30 volts. Check generator and load bank meters after first five minutes then every fifteen minutes to be sure generator is loaded properly. Check oil level frequently during run-in; add oil if needed. After one hour (minimum) place V/A control in minimum position, then turn off load bank to remove load. Run engine several minutes at no load. Stop engine and let cool. 4 Engine Exhaust Pipe Repeat procedure if wetstacking is present. 2 3 4 1 OM-492 Page 41 9-3. Run-In Procedure Using Resistance Grid S-0684 Stop engine. Do not touch hot exhaust pipe, engine parts, or load bank/grid. Keep exhaust and pipe away from flammables. 1 Resistance Grid Use grid sized for generator rated output. Turn Off grid. 2 Welding Generator 3 Weld Cables Connect grid to generator weld output terminals using proper size weld cables with correct connectors (polarity is not important). 4 Voltmeter 5 Clamp-On Ammeter Connect voltmeter and ammeter as shown, if not provided on generator. Start engine and run for several minutes. Set grid switches and then adjust generator V/A control so load equals ...
