Error Displays (Troubleshooting)

When an error occurs, the No.1 display shows the error code. Take necessary measure according to the error code, referring the table below.

Note: If the input value exceeds the display limit (-1999 to 9999), though it is within the control range,

will be displayed under -1999 and

above 9999. Under these conditions, control output and alarm output will operate normally.

For details on the control range, refer to the E5CN/E5AN/E5EN Digital Temperature Controllers User's Manual Basic Type (Cat. No. H156).

✽ These errors are displayed only when the PV/SP is displayed. Errors are not displayed for other displays.
