Notes:
*)
If the signal output of X1 & X2 is 10 V or 20 mA, the cause of the error is one of the follow-
ing:
●
The selected measuring range of PM2.5 & PM10 is below the measured PM2.5 or PM10
value. E.g., if the selected measure range is 0...50 μg/m
PM10 value is 100 μg/m
higher range resolves this error.
●
If the signal output is still 10 V or 20 mA after changing the selected measuring range,
the cause is a PM2.5 communication error.

Sensor data refresh frequency
The sensor data refresh frequency only applies to smart work mode (DIP8 = ON). It is de-
fined as per the real-time concentration of PM2.5 & PM10 and the interval is 3...8 min. The
data is updated under the following conditions:
