TEST PROCEDURE

NOTE: In this test procedure, the positive output stud is used for common.

1.Using the 5/16” nut driver, open the control panel and tilt out. Remove the control board cover. Start the machine.

WARNING

There are high voltages present inside the control box while the machine is running. THE VOLTAGES ARE HIGH ENOUGH TO KILL. Use extreme cau- tion to avoid the backside of the receptacles, breakers, and terminal

strip while checking voltages inside the control box.

2.Put the range switch in the CV position on stick & wire machines, or in the 90 tap on stick only machines.

3.Check the voltage at the control board from J7 pin 10 to common at each tap on the range switch. See Figure F.28. See table F.1 below for approximate voltage reading from each tap.

4.If any of the voltages in the table are incorrect, replace the range switch.

5.If the test is complete, replace the control board cover and close the control panel.
