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.
Display range over
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).

Motor calibration error (Displayed on the No. 2 Display)
Motor calibration has ended with an error.
First, correctly connect the wiring for the potentiometer, open output, and
close output.
Execute the motor calibration again.
When motor calibration is executed, open output will operate and then
close output will operate. However, as the value is incorrect, the result
turns out to be an error.
