6.3 Exchange of Sensor Element
Consider static electricity See point 3.
Sensor should always be installed without power applied:
Unplug basic PCB AT03 carefully from the bottom part.
Unplug old sensor element from the PCB.
Take the new sensor out of the original packing.
Plug the sensor element in the PCB.
Replug the PCB AT03 in the terminal blocks X4, X5 carefully.
Calibrate according to section 5.
7 Troubleshooting
7.1 Analog Mode
Trouble
Cause
Solution
Output signal < 3 mA / 1,5 V
and/or control voltage < 30 mV
Jumper 0-20 % not set
Check jumper position
Measure tension at X4:
only for starting signal 2V/4 mA Power voltage not applied
Two-wire: Pin 1 (+) and 4 (-)
Three-wire: Pin 1 (+) and 2 (-)
PCB AT03 not plugged in correctly at X4
and X5
Replug PCB correctly
Wire break
Check the wiring
Output signal > 22 mA /220 mV Short-circuit
Check the wiring
Control voltage does not reach
the calculated value
Sensor element not calibrated
Calibrate sensor element
Sensor sensitivity < 30 %
Replace sensor element
No reaction of the output signal
in spite of gas concentration
Power voltage not applied
Measure tension at X4
Signal (Pin 4) not wired correctly
Check the wiring
8 Cross-sensitivity Data
The cross sensitivity can be read from the table Technical Data (see section 9). The table doesn’t claim to
be complete. Other gases can have an influence on the sensitivity, too. The indicated sensitivity data
are only standard values referring to new sensor elements.
