Action
Control continues, allowing normal operation. The message is displayed when the PV, PV/SP, or PV/MV is dis-
played.
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 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 at Error
The control outputs and alarm outputs turn OFF. An error message is displayed when the PV, PV/SP, or PV/
MV is displayed.
When the manual MV is set, the control output corresponds to the set value.
For alarm outputs, the operation indicators and status normally turn OFF, but they will turn ON if the “Open in
alarm” parameter for alarms 1, 2, or 3 in the advanced function setting level is set to
n-c
(Open in alarm).
