Airnet II Particle Sensor Operations Manual
Chapter 1
Getting Started
Physical Description
Top
Two LEDs are located on the top of each Airnet II particle sensor chassis:
• Status LED
– Indicates the operational status of the instrument.
• Activity LED
– Flashes when a particle is detected.
When connected to Facility Net software, the LED is controlled by Facility Net’s alarm
settings. When disconnected from Facility Net, you can set the unit to run the status
LED two distinct ways.
•
Set the status LED to flash green when disconnected.
•
Set the status LED to represent the internal state of the flow and laser status.
The LED will normally remain green, except for a low flow or laser status error.
The failure state depends upon how the particle sensor is configured in Facility
Net. You can set the LED to appear green, flashing, or dimmed.
