1. Sensor Adjustment
The amplification factor of the sensor can be adjusted by the gain switch (see figure 6).
Figure 6: View of sensor board
2. Transmitter Adjustment
The analog output range of the DIN-rail transmitter can be adjusted with the
potentiometers
ZERO and SPAN . In center position, the ZERO potentiometer maps the
lower measuring range to a current output of 4mA. By adjusting the potentiometer to the
lower or upper end, the current output is increased or decreased by up to 4mA
respectively.
If the SPAN potentiometer is in center position, the upper measuring range is mapped
to a current output of 20mA. By adjusting the potentiometer to the lower or upper end,
the current output is increased or decreased by up to 4mA respectively.
However, the current output is limitated to a maximum range of 3.8mA to 20.5mA.
8.3 Operation
The emerging particle load is continuously captured and output as an analog value,
corresponding to the previously adjusted settings.
In case of a communication error between sensor and transmitter, the device outputs
3mA.
