Receptacle RC3 socket connections to the welding power source control circuitry are as follows:

Socket A: Contactor control switch connection.

Socket B: Contactor control switch connection.

Socket C: Amperage or voltage control connection (maximum side).

Socket D: Amperage or voltage control connection (minimum side).

Socket E: Amperage or voltage control connection (wiper contact).

IMPORTANT: Use only one CV-2 receptacle at a time for remote current and/or voltage control or welding gen- erator may not work properly.

REMOTE-14

The 14-socket REMOTE-14 receptacle RC4 provides a junction point for connecting a Remote Amperage/Volt- age Control and/or a Remote Contactor Control or a wire feeder providing switch closure for contactor con- trol to the control circuitry of the welding generator. To make connections, align keyway, insert plug fully into re- ceptacle, and rotate threaded collar clockwise.

Receptacle With Socket Designations

The command signals required and the output signals available at the sockets of receptacle RC4 by means of the welding generator control circuitry are as follows:

Socket A: Up to 10 amperes of 24 volts ac 60 Hz with respect to socket G (circuit common), pro- tected by circuit breaker CB6.

Socket B: Weld contactor control for 24 volts ac wire feeders providing contact closure to socket A.

Socket C: 0 to +10 volts dc with respect to Socket D; reference voltage for output command sig- nal depends on the AMPERAGE & VOLT- AGE ADJUSTMENT control setting on the unit.

Socket D: Control circuit common for remote control device.

Socket E: Output command signal to wiper of remote control potentiometer, 0 volts equals ma- chine minimum; +10 volts equals machine maximum.

Socket F: Not used.

Socket G: 24 and 120 volts ac circuit common.

Socket H: Not used.

Socket I: Up to 10 amperes of 120 volts ac 60 Hz with respect to socket G (circuit common), pro- tected by circuit breaker CB5.

Socket J: Weld contactor control for 120 volts ac wire feeders providing contact closure to socket I.

Socket K: Machine chassis.

Socket L: Not used.

Socket M: Not used.

Socket N: Not used.

IMPORTANT: Use only one CV-2 receptacle at a time for remote current and/or voltage control or welding gen- erator may not work properly.
