CONTROLLING NON-LINCOLN AUXILIARY EQUIPMENT

Custom motion control and/or other auxiliary equipment can be powered using the terminal strip and relays. To use non-Lincoln motion control and/or flux hoppers, fol- low instructions below. See Figure A.4.

1.Remove all input power to the MAXsa™ 10 CON- TROLLER 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 a plug button from one of the .875” (22.2mm) access holes on the bottom of the MAXsa™ 10 CON- TROLLER control box. Install a suitable strain relief to protect the leads. See Figure A.1.

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. See the Wiring Diagram.

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

.

6.Any custom or non-Lincoln equipment can be powered by the normally open contacts from relays CR1, CR2, or CR3. The contacts for CR1 are connected to the terminal strip blocks #3 through #8. The contacts for CR2 are connected to terminal strip blocks #10 through #15. The contacts for CR3 are connected to terminal strip blocks #17 through #22. See Figure A.3.

CR1 and CR2 relay coils are in parallel and are BOTH turned ON and OFF as determined by the Travel Options setting (P12 in the Set-up Menu) as long as the TRAVEL MODE is set to AUTO. CR3 turns ON with the START command and OFF with the STOP Command.

7.The supply voltage to power the devices is provided by the end user. As shipped, the MAXsa™ 10 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 connects a supply to the AUX blocks #48 and #49, this voltage will be jumpered to the CR2 and CR3 relay inputs on ter- minal strip blocks #11, #17, and #18.

NOTE: The CR1 relay is not connected to the AUX terminal strip blocks; the customer must con- nect power to this relay if it is to be used. See relay ratings listed earlier.

8.Connect input supply voltage per the Auxiliary Input Power Connection Instructions listed earlier.

9.The relays can also be used to provide contact closure for any interfacing signals out using the normally open contacts. An external auxiliary supply voltage would not be necessary to use the relays as hard contact clo- sure out signals.

NOTE: The CR1 relay as shipped does not have AUX leads connected to it. This relay operates as described above and has two normally open / normally closed contacts that could be used as a signal out when interfacing to PLC’s or cus- tom controls.
