Automated Laser Power Control
Airnet II 4-Channel particle sensor units contain an automated laser power control that
automatically shuts off the laser power after 10 seconds of continuous bad flow (flow
rate that is ± > 15% of the specified flow rate).
The laser power is restored after 10 seconds of continuous good flow.
Detector Board Monitor
The Airnet II 4-Channel particle sensor has an automatic monitor to assure the
detector board is operating correctly. In many applications the normal condition is
no
particle counts being detected
for an extended period of time.
NOTE:
If installation of the Airnet II 4-Channel particle sensor will
prevent access to its RS-232 port (needed for configuration),
configure the particle sensor first and then install the unit. See
