REMOTE CONTROL
The AIR VANTAGE® 500 CUMMINS is equipped with a 6-pin and a 14-pin connector. The 6-pin connector is for connecting the K857 or K857-1 Remote Control or for TIG welding, the K870 foot Amptrol or the K963-3 hand Amptrol. When in the CC-STICK or CV-WIRE modes and when a remote control is connected to the 6-pin Connector, the auto-sensing circuit automatically switches the OUTPUT control from control at the welder to remote control.
When in the DOWNHILL PIPE mode and when a remote control is connected to the 6-Pin or 14-Pin connector, the output control is used to set the maxi- mum current range of the remote.
EXAMPLE: When the OUTPUT CONTROL on the welder is set to 200 amps the current range on the remote control will be 40-200 amps, rather than the full 40-300 amps. Any current range that is less than the full range provides finer current resolution for more fine tuning of the output.
The 14-pin connector is used to directly connect a wire feeder control cable. In the CV-WIRE mode, when the control cable is connected to the 14-pin con- nector, the auto-sensing circuit automatically makes the Output Control inactive and the wire feeder volt- age control active.
WARNING
NOTE: When a wire feeder with a built in welding voltage control is connected to the 14-pin connec- tor, do not connect anything to the 6-pin connec- tor.

AUXILIARY POWER RECEPTACLES
Start the engine and set the “IDLER” control switch to the “High Idle” mode. Voltage is now correct at the receptacles for auxiliary power. This must be done before a tripped GFCI receptacle can be reset proper- ly. See the MAINTENANCE section for detailed infor- mation on testing and resetting the GFCI receptacle.
The auxiliary power capacity of the AIR VANTAGE® 500 CUMMINS is 12,000 watts of 60 Hz, single phase or 20,000 watts of 60Hz, three phase power. The auxiliary power capacity rating in watts is equivalent to volt-amperes at unity power factor. The maximum per- missible current of the 240 VAC output is 50 A. The 240 VAC single phase output can be split to provide two separate 120 VAC outputs with a maximum per- missible current of 50 A per output to two separate 120 VAC branch circuits. The output voltage is within
± 10% at all loads up to rated capacity.
The AIR VANTAGE® 500 CUMMINS has two 20 Amp-120VAC single phase(5-20R) GFCI duplex receptacles, one 50 Amp-120/240 single phase VAC (14-50R) receptacle and one 240VAC three phase (15-50R) receptacle. The auxiliary power receptacles should only be used with three wire grounded type plugs or approved double insulated tools with two wire plugs. The current rating of any plug used with the system must be at least equal to the current capacity of the associated receptacle.
A 240VAC 3 phase plug is provided loose with the machine.
NOTE: The two 120V GFCI receptacles and the two 120 volt circuits of the 120/240V receptacle are con- nected to different phases and can not be paralleled.
STANDbY POWER CONNECTIONS
The AIR VANTAGE® 500 CUMMINS is suitable for temporary, standby or emergency power using the engine manufacturer’s recommended maintenance schedule.
The AIR VANTAGE® 500 CUMMINS can be perma- nently installed as a standby power unit for 240 volt-3 wire, 50 amp service. Connections must be made by a licensed electrician who can determine how the 120/240 VAC power can be adapted to the particular installation and comply with all applicable electrical codes. The following information can be used as a guide by the electrician for most applications. Refer to the connection diagram shown in Figure A.1.
1.Install the double-pole, double-throw switch between the power company meter and the premis- es disconnect.
Switch rating must be the same or greater than the customer’s premises disconnect and service over cur- rent protection.
