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.
