3.7 Error messages at non-specified sensor temperatures
The pyrometer gives the following error messages for the protection of the electronics and the
machines if the temperature of the sensor head is out of specified values:
Excess of specified sensor head temperature (corresponding to the model: 85 °C or
180 °C):
- Output of the serial interface code 75550
-
Output of the analog output: 22 mA at 0/4 to 20 mA, 5 V at 0 to 5 V,
excess of end of measuring range at thermocouple output
- The relay is de-energized (contact open)
- Display of (IN 510 or IN 520): ERR 1 instead of the temperature reading
Sensor head temperature falls below specified value (0 °C):
- Output of the serial interface code 74440
-
Output of the analog output: 22 mA at 0/4 to 20 mA, 5 V at 0 to 5 V,
excess of end of measuring range at thermocouple output
- The relay is de-energized (contact open)
- Display of (IN 510 or IN 520): ERR 2 instead of the temperature reading
There is no error message if the converter temperature runs out of its specified operating
temperature.
