Troubleshooting

2.Preliminary Troubleshooting

The following is a check list of initial steps to perform.

•Check all LED indicators, fuses and circuit breakers. Refer to Table 6-1.

•Visually examine all areas of the CCR. Do burnt or loose connections/parts exist?

•Is the input voltage present and within +10 to –5% of nominal?

•Check all the fuses.

•Are the wire harness connectors to the control board fully seated?

•Have the PCBs been adjusted in accordance with the instruction manual?

•If the CCR works in local but not Remote, check the voltage on the Remote control lines.

•Can the CCR be re-energized by turning the rotary switch from OFF to Step B1 (B10)?

•Short the output of the CCR with an AWG 8 wire, and turn on the CCR. If the regulator operates normally, the problem is probably load related.

•If the CCR turns on and then shuts off after a few seconds and the ammeter has a high current reading, the problem is overcurrent. Adjust the output current accordingly. If the output current is not adjustable, replace the control board restart the regulator.

•If the CCR still fails in overcurrent, replace the SCR and restart.
