NOTE: TRAVEL AUTO and TRAVEL ON should not be closed at the same time. Either one OR the other should be closed at any time, and must remain closed to keep particular Travel Mode active. If neither switch is closed at any time, travel will be turned OFF, regardless of the welding state. Inching and Flux switches will activate their particular function when the switch is closed, and will cease when opened. The START and STOP switches are MOMENTARY and only need to be closed for a short period of time to start or stop the weld sequence.

CONTROLLING NON-LINCOLN

AUXILIARY EQUIPMENT:

Custom motion control and/or other auxiliary equip- ment can be powered using the terminal strip and relays. To use non-Lincoln motion control and/or flux hoppers, follow instructions below.

1.Remove all input power to the POWER FEED™ 10A CONTROLLER including any auxiliary power supplies.

2.Remove the wire duct cover to gain access to the leads on the right side of the terminal strip.

3.Remove one of the plug buttons located on the bot- tom of the POWER FEED™ 10A CONTROLLER control box and install some type of strain relief for the auxiliary control leads.

4.Remove the leads going from the terminal strip to the corresponding connectors, i.e. terminal strip blocks #11, #13, and #16 for the 4-pin TC-3 Travel Carriage or terminal strip blocks #19, #20, and #23 for the 3-pin Automatic Flux Hopper.

5.These loose leads can be taped and secured in the wire duct.

6.Any custom or non-Lincoln equipment can be pow- ered by the normally open contacts from relays CR1, CR2, or CR3. The normally open contacts for CR1 are located on terminal strip blocks #5 and #6. The normally open contacts for CR2 are located on terminal strip blocks #12 and #13. The normally open contacts for CR3 are located on terminal strip blocks #19 and #20. CR1 and CR2 are BOTH turned ON when the weld sequence starts and are BOTH turned OFF when the weld sequence stops as long as the TRAVEL MODE Switch is in the AUTO position.

7.The input supply voltage to power these devices is provided by the end user. As shipped, the PF-10A has the auxiliary supply blocks (terminal strip blocks #48 and #49) connected to the CR2 relay and CR3 relay inputs, respectively. When the end user con- nects a supply to the AUX blocks #48 and #49, this voltage will be jumpered to the CR2 and CR3 relay inputs on terminal strip blocks #11, #17, and #18. Note – the CR1 relay is not connected to the AUX terminal strip blocks; the customer must connect power to this relay if it is to be used. See relay rat- ings listed earlier.
