Replacing AQS2100
NOTICE! Only trained engineers may replace the sensor module.
The sensor module must be replaced under the following conditions:
●
QSM2162 (PM2.5 + r.h. + temperature): An output signal of 10 V/5 V/20 mA is provided
at signal outputs X1 and X2 and an output signal of 0 V/4 mA at signal output X3.
●
QSM2100/QSM2162 (PM2.5 + PM10 + temperature): An output signal of
10 V/5 V/20 mA is provided at signal output X1 and an output signal of 0 V/4 mA at sig-
nal output X2.
Replacing the sensor module:
NOTICE! As the replacement on QSM2162 and QSM2100 is identical, the steps to re-
place the QSM2162 sensor module serve as an example.
1. Detach the sub-housing from the main housing.
CAUTION! Avoid touching any exposed electrical elements.
