Check List for Common Problems

This section provides a brief checklist of common failures.

1. Verify that the AC power cord is connected to the TC-5942B.

Make sure that the power cord is firmly plugged into the power module on the left side. Also

make sure that the power source for the TC-5942B is energized.

2. Verify that the TC-5942B power switch is depressed.

3. Verify the line voltage.

The line voltage to the power source should be 100 ~ 240 VAC.

4. Verify the compressed air and air cables.

The compressed air to the TC-5942B should be 5 ~ 7.5 bar.

5. Verify external cables provide good connections.

6. Verify shield box specifications if the shield box is functional.

NOTE:

First verify that the problem is not a result of an external connection before considering the

problem is with the shield box. Then isolate the failure to the shield box before troubleshooting or

repairing the TC -5942B. Verify the shield box performance is to specification while troubleshooting

the problem.
