Wiring

: please note that 24 VDC is the absolute maximum value of voltage 

used. Because of this, the user should pay attention to possible voltage peaks 
when using the device. Care must be taken especially when the device is 
powered from the power supply in an industrial environment.

5. OPERATION 

Dumo measures solid particles in ambient air. The device has “Alert” and 
“Alarm” levels which correspond to certain dust concentration levels above the 
“Normal”. These three levels are indicated by Red, Yellow and Green colours 
of indicator led in front cover. 

Green
