11.1
Errors (
Errors are exclusively generated when a communication trouble occurs between the sensor and
the internal board. Errors are identified in the following format
the error code). No corrective action is possible for the operator. In this case, sensors must be
returned to the manufacturer or his local agent.
Number Cause
35 to
Communication error with the sensor
39
40 to
Communication error with the infrared sensor block (OLCT

IR).

Faults (
A fault signal alerts about a material fault (voltage, sensor etc...). Here below is the list of possible
faults. Please note that the occurrence of more than one fault is not displayed by showing a
sequence of the reference code numbers but rather by adding them up to each other.
If, for example, a zero fault (code 1) and a sensitivity fault (code 2) are detected, the display will
show the fault code 3. In this case the analogic output signal will equal 1 mA.
N°
Cause
1
Zero fault after calibration
2
Sensitivity fault after calibration
4
Sensor worn out after calibration
8
Memory problem.
16
Excessive negative signal.
32
Measuring beyond upper range.
64
Fault after an internal control
256
Line voltage too low.
512
RAM memory problem.
1024 Memory programmation problem.
