Input sensor is not properly
connected.
Connect the input sensor with the correct
polarity.
–
Input is short-circuited during the
use of the type R thermocouple.
Change the parameter setting of
to 3,
and check the the reading. If the reading is
around the room temperature, there is no
short-circuiting. The error code appeared
because the type R thermocouple tends
to show large error around the room
temperature.

The input sensor in use is not
appropriate for the version of
PXR3 you ordered.
Use the right sensor for your PXR3 or the
right PXR3 for the sensor you use.
2, 11
The connection of the input is
loose.
Fasten the terminal connection.
–
Input circuit is opened or shorted. Replace the sensor, or solve the short
circuit.
–
Sensor is failed.
Replace the sensor.
–
Process temperature is too high or
too low.
Replace the sensor appropriate for the
measurement range.
