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.
However, 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.
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.
