Meaning
Though this is not an error, this is displayed when the process value exceeds the display range when the con-
trol range is larger than the display range ( − 1999 to 9999 or − 199.9 to 999.9).
• When less than " − 1999 or − 199.9"
• When less than "9999 or 999.9"
Action
Control continues, allowing normal operation. An error message is displayed when "process value" or "PV/SP"
are displayed.

Memory error
Meaning
Internal memory operation is in error.
Action
First, 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
Control output and alarm output turn OFF. (Current output is approx. 0 mA).
