6-2 Troubleshooting & Error Indication
Operation at Error
• After an error occurs, the error is displayed and the alarm output
functions as if the Upper-Limit has been exceeded.
• If you configure the Input Error Output parameter in the Advanced
Setting function group to ON, the Alarm 1 output turns ON whenever
an input error occurs.
• An error message is displayed when the PV, PV/SP, or PV/MV is
displayed.
• The control output turns OFF when the manual MV, MV at stop, or
MV at PV error is configured, the control output corresponds to the
configured value.
Display Range Exceeded
Meaning
This is not an error, but rather, it is displayed if the process value (sensor
input) 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

Action
Control continues, allowing normal operation. The message is displayed when
the PV, PV/SP, or PV/MV is displayed.
