TEST PROCEDURE

1.Set the machine to the following settings, then start the machine:

Control dial to 1 (min)

Range dial to 90A max

Idler switch in the “Auto” position

Output control source (2-4) switch in the “Welding Terminals Remotely Controlled” position.

2.As the unit powers up, the display will step thru its’ initialization sequence. As soon as the dis- play shows “---”, the user must toggle the idler switch from “Auto” to “High” 5 times in 5 sec- onds. The display will read “tal”, then “000”. The idler switch must be returned to the “Auto” posi- tion. If the user misses toggling the Idler switch 5 times in 5 seconds, the machine will default to normal operation, and step 1 & 2 must be repeat- ed.

3.Toggle the 2-4 switch to the “Welding Terminals Always On” position. The display will read the phase 1 no load exciter voltage. The voltage should be between 400-525 Vac. Return the 2-4 switch to the “Welding Terminals Remotely Controlled” position.

4.Toggle the Idler switch from “Auto” to “High”, then back to “Auto”. The display should read “001”. Repeat step 3 to read the phase 2 no load exciter voltage.

5.Toggle the idler switch from “Auto” to “High”, then back to “Auto”. The display should read “002”. Repeat step 3 to read the phase 3 no load exciter voltage.

6.For machines equipped with G2713-1 boards, toggle the Idler switch once from “Auto” to “High”. The display should read “003”. For machines equipped with G2713-2 & 3 boards, toggle the idler switch 3 times from “Auto” to “High” to “Auto” till the display reads “000” again.

7.Turn the control dial to 10 (max). Toggle the 2-4 switch to the “Welding Terminals Always On” position. Apply a grid load so that the machine’s output is 565-585 amps at a minimum of 30 VDC. The display will read the phase 1 exciter voltage under load. Record the phase 1 exciter voltage under load. Return the 2-4 switch to the “Welding Terminals Remotely Controlled” posi- tion.

8.Toggle the Idler switch from “Auto” to “High”, then back to “Auto”. The display should read “001” (or “004” for machines equipped with G2713-1 board). Repeat step 7 to read the phase 2 exciter voltage under load.

9.Toggle the idler switch from “Auto” to “High”, then back to “Auto”. The display should read “002” (or “005” for machines equipped with G2713-1 board). Repeat step 7 to read the phase 3 exciter voltage under load.

10.If all exciter voltage readings on the display are correct, the exciter board is properly calibrated and the test is complete. If the average of the three exciter voltage readings under load is under 350VAC, then the board must be replaced.
