Error Display
When an error has occurred, the No.1 display alternately indicates error codes together with the current display
item.
This section describes how to check error codes on the display, and the actions you must take to remedy the
problem.
Meaning
The input value has exceeded the input indication range: −1999 to 9999 or −199.9 to 999.9
Action
Check the wiring of inputs for miswiring, disconnections, short-circuits and the input type.
If no abnormality is found in the wiring and input type, turn the power OFF then back ON again. If the display
remains the same, the E5AZ/E5EZ must be repaired. If the display is restored, then a probable cause could be
electrical noise affecting the control system. Check for electrical noise.
Operation at error
After the error occurs, the error is displayed, and control output functions turn OFF. (Current output is approx.
0 mA).
Alarm outputs function as if the upper limit value has been exceeded.
When “output input error” (advanced function setting level) is set to ON, the alarm 1 output turns ON when an
input error occurs.
An error message is displayed when “process value” or “PV/SP” are displayed.
