E5@C Digital Temperature Controllers User’s Manual (H174)
Meaning
Though this is not an error, it is displayed if the process value exceeds the display range when the
control range is larger than the display range.
The display ranges are shown below (with decimal points omitted).
• When less than −1,999: [[[[
• When more than 9,999: ]]]]
Operation
Control continues, allowing normal operation. The value will appear in the display for the PV.
Meaning
There is an error in internal circuits.
Action
First, turn the power OFF then back ON again. If the display remains the same, the Digital Controller
must be repaired. If the display is restored, then the probable cause is electrical noise affecting the
control system. Check for electrical noise.
Operation
The control, auxiliary, and transfer outputs turn OFF. (A linear current output will be approx. 0 mA. A
linear voltage output will be approx. 0 V.)
