• When setting 1 (MV at PV Error) is being used, set the MV at PV Error in
variable type D5/95. For details, refer to MV at PV Error on page 74.
• If this parameter is set to 2: stop control, control will stop when an error
occurs and will not be restored automatically even if the error is cleared.
Execute the Reset Error operation command to restore operation.
• Each set value determines the operation for different errors, as shown in
the following table.
Note Applies to the channel associated with the CT (current transformer).
For example, when the Control Output 1 Assignment is set to Channel 1 Con-
trol Output (Heating) and the CT1 Assignment is set to OUT1, channel 1 will
operate according to the Operation During Error (Selection B) setting if a
heater burnout is detected at CT1.
Since CT1 is associated with channel 1, channel 1 will operate according to
the Operation During Error (Selection B) setting if an error is detected at CT1.
