Error messages

The controller can detect various types of malfunctions when reading an analog signal. It differentiates between ADC converter failure, processor or expansion board analog input error, and for thermocouples, it detects exceeding the maximum adjustable value, reversed thermocouple polarity, and often the wrong type of selected thermocouple. Any error will cause the program to stop (if it was started) and prevent the program from starting. The error is evident on the display according to the following indicators:

•the status bar is displayed in red

•an inscription appears in the middle of the status bar Error followed by an error code

•a text abbreviation of the error is displayed at the temperature location in the respective zone

The following table describes the errors:

Error number	Displayed error and description	Error removal
1	ETHI Maximum temperature exceeded	Check the type of thermocouple at the corresponding analog input. Adjust the control constants when controlling near the maximum adjustable temperature. Increase the maximum adjustable temperature if the connected device, type of thermocouple and material allows it
2	EPOL Reverse thermocouple polarity	Rotate the thermocouple for correct polarity
3	ETYP Wrong type of thermocouple	Change the thermocouple type in Settings (Type of analog input Zx) according to the thermocouple actually connected
4	EADC ADC converter error	Analog-to-digital converter error in the processor or expansion board - contact the controller manufacturer (Introduction)
5	ECON Error in the analog part of the input	Error of the analog part of the input in the processor or expansion board - contact the controller manufacturer (Introduction)

The error code in the status bar identifies the error. Each digit of the code corresponds to a zone: the first digit (thousands) belongs to zone 1 (Z1), and the fourth digit (units) belongs to zone 4 (Z4). The actual digit then expresses the error code according to the above error table. For example, code 3000 (pictured above) indicates the wrong type of thermocouple in zone 1.

If it is possible to zoom the module (Increase area module), then by touching the error message a description of the corresponding shortcut will be displayed (see following picture).
