This error is output only during temperature input, and is displayed for
two seconds when the power is turned ON.
Calibration data is in error.
Must repair.
Both control output functions and alarm output functions operate. How
ever, note that readout accuracy is not assured.
Though not an error, this is displayed when the process value exceeds the
display range when the control range (setting range ±10%) is larger than
the display range ( 1999 to 9999).
When less than  1999"
When greater than 9999" [
Control continues, allowing normal operation.
The communications read/write data assignment is in error.
This error occurs in the following instances:
When the same data is set to two or more channels
When write only data is set to a read data assignment
When read only data is set to a write data assignment
Check and reset the communications read/write data assignment data in
the option mode. For details, see 6.4 Data Assignments."
Control output functions turn OFF (2mA max. at 4 to 20mA output, and
output equivalent to 0% in case of other outputs).
Alarm output functions turn OFF.
