Lincoln Electric IM849 manual Interfacing to the Switch Panel Controls

A-4 INSTALLATION A-4

4.Replace the Switch Panel on the POWER FEED™ 10A CONTROLLER with the blank panel included with the pendant box.

5.Connect the Switch Panel to the mating 10-pin con- nector inside the pendant box.

6.Fasten the Switch Panel to the pendant box.

7.Connect the 14-pin/9-pin pendant cable to the mat- ing cable connector on the bottom of the POWER FEED™ 10A CONTROLLER and the mating cable connector on the pendant.

8.The remote pendant is now ready to be used.

Interfacing to the Switch Panel Controls:

The Switch Panel circuits can be accessed on the screwless terminal strip. Easy access to these circuits enables the POWER FEED™ 10A CONTROLLER to interface with custom controls or PLC’s. These circuits must see a contact closure to function properly.

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

2.Remove the fasteners from the Switch Panel and disconnect the Switch Panel from the wire harness. The Switch Panel should be stored in a secure

CAUTION

place in the event that it is needed in the future.

The Switch Panel should not be left in the POWER FEED™ 10A CONTROLLER if the switches are not connected. This could cause a safety concern due to the fact that the switches will not stop the welding sequence, etc.

3.Jumper the wire harness connector (J2) to the mat- ing 10-pin connector (P2P) that is floating inside the control box (See Wiring Diagram).

4.Replace the Switch Panel on the POWER FEED™ 10A CONTROLLER with the blank panel included with the pendant box.

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

6.Remove the leads going to the Pendant 14-pin con- nector from the right side of terminal strip blocks #39, #40, #41, #42, #43, #44, #45, #46, & #47. (Note – see Auxiliary Input Power Connection Instructions on how to remove/install wires to the screwless terminal strip)

7.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 interfacing leads.

8.Connect the interfacing leads to the Switch Panel circuits on the terminal strip (see Wiring Diagram for terminal strip designations). The supply for START, STOP, and INCH UP comes from SWITCH GROUP #1 SUPPLY on block #39. The supply for TRAVEL AUTO, TRAVEL ON, FLUX FILL, and INCH DOWN comes from SWITCH GROUP #2 SUPPLY on block #43.

9.To activate any of the Switch Panel circuits, a con- tact closure must be established between the sup- ply and the particular circuit it is referenced to – for instance, to start the weld sequence, a contact clo- sure must be established momentarily between ter- minal strip blocks #39 (SUPPLY) and #40 (START). See FIGURE A.2.

10.The leads from the 14-pin connector that were removed from the terminal strip can be taped and secured in the wire duct located next to the termi- nal strip.
