Calibration data error
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.
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).
• When less than “-1999” [
]
• When greater than “9999” [
]
Control continues, allowing normal operation.
