A-3 Error Displays
When an error occurs, the error contents are shown on the No. 1 or the No. 2 display.
This section describes how to check error codes on the display, and the actions to be taken to remedy
the problems.
s.err
Meaning
The input value has exceeded the control range. *
The input type setting is not correct.
The sensor is disconnected or shorted.
The sensor wiring is not correct.
The sensor is not wired.
* Control Range
Resistance thermometer,
thermocouple input:
ES1B input:
Analog input:
Action
Check the wiring of inputs for miswiring, disconnections, and short-circuits and check the input type.
If no abnormality is found in the wiring and input type, turn the power OFF then back ON again.
If the display remains the same, the Controller must be replaced. If the display is restored, then the
probable cause is electrical noise affecting the control system. Check for electrical noise.
Note: With resistance thermometer input, a break in the A, B, or B' line is regarded as a disconnection.
Operation
After an error occurs, the error is displayed and the alarm outputs function as if the upper limit has
been exceeded.
If an input error is assigned to a control output or auxiliary output, the output will turn ON when the
input error occurs. The error message will appear in the display for the PV.
Note: The heating and cooling control outputs will turn OFF. When the manual MV is set, the control output is
determined by the set value.
