Lincoln Electric 500 Engine Operation, Circuit Breakers, 21. 120VAC SINGLE PHASE RECEPTACLES

B-5 OPERATION B-5

20. CIRCUIT BREAKERS

These circuit breakers provide separate overload current protection for each 120V circuit at the 240V single phase receptacle, each 120V single phase receptacle, the 240V three phase receptacle, the 120VAC in the 14-Pin connector, the 42VAC in the 14-Pin connector and battery circuit overload protec- tion.

21. 120VAC SINGLE PHASE RECEPTACLES

These two 120VAC (5-20R) receptacles with GFCI protection provide 120VAC single phase for auxiliary power. Each receptacle has a 20 amp total rating. They are designed to protect the user from the haz- ards of ground faults. When the GFCI has tripped there will be no voltage available from the recepta- cle. Refer to the AUXILIARY POWER RECEPTA- CLES section in the installation chapter for further information about these receptacles. Also refer to the AUXILIARY POWER OPERATION section later in this chapter.

22. GROUND STUD

Provides a connection point for connecting the machine case to earth ground. Refer to “MACHINE GROUNDING” in the Installation chapter for proper machine grounding information.

23. 240VAC THREE PHASE RECEPTACLE

This is a 240VAC (15-50R) receptacle that provides 240VAC three phase auxiliary power. This recepta- cle has a 50 amp rating.

ENGINE OPERATION

STARTING THE ENGINE

1.Open the engine compartment door and check that the fuel shutoff valve is in the open position (lever to be in line with the hose).

2.Check for proper oil level and coolant level. Close engine compartment door.

3.Remove all plugs connected to the AC power receptacles.

4.Set IDLER switch to “AUTO”.

5.Set the RUN/STOP switch to “RUN”. Observe that the engine protection and battery charging lights are on. The engine protection light may turn off after 5 seconds or remain on until the engine is started.

6.Within 30 seconds, press and hold the engine START button until the engine starts. If the engine does not start within 30 seconds the RUN/STOP switch must be returned to the STOP position, then return to step 5.

7.Release the engine START button when the engine starts.

8.Check that the engine protection and battery charg- ing lights are off. Investigate any indicated problem.

NOTE: The engine will go through a 3 minute warm- up cycle if cold. If the engine coolant is still warm from recent operation, the engine will go immediately to high idle and then to low idle if the idle switch is in the “AUTO” position.

COLD WEATHER STARTING

With a fully charged battery and the proper weight oil, the engine should start satisfactorily even down to about 0°F(-18°C). If the engine must be frequently started below 10°(-12°C), it may be desirable to install the optional ether start kit (K887-1). Installation and operating instructions are included in the kits.

STOPPING THE ENGINE

1.Switch the RUN/STOP switch to “STOP”. This turns off the voltage supplied to the shutdown solenoid. A backup shutdown can be accomplished by shutting off the fuel valve located on the fuel line.
