Configuration jumper for OUT2 output
The output OUT2 can be used as a voltage or current output. The output is
configured by the jumper on top of the PCB. The configuration of the output can be
changed by moving the jumper to the desired position. The output has to be
reconfigured before the unit is powered up.

and current position
Self-diagnostics
The system contains complete self-diagnostic procedures that are executed
automatically when the sensor is in operation. Sensors with display show a wrench if
an error is found. The wrench is shown during the first seconds after power up and if
the measuring range 2000 ppm is exceeded. The output OUT2 indicates the same
information by setting the output to 1 V or 2 mA.
PLEASE NOTE!
The sensor accuracy is defined at continuous operation (at least 3 weeks after
installation)
