Troubleshooting (cont’d)
Diagnosing Faults
The controller includes a number of features designed to help the user track down operational, wiring, or
internal controller faults. The diagnostic LED mounted next to the calibrator connectors on the front of the
controller serves as a simple diagnostic tool. Use the table below to identify faults. Faults are cleared by
re-initiating the start sequence.
