Getting Started
The Airnet II particle sensor is a laser-optical aerosol particle sensor that accurately
detects, counts, and measures particles suspended in air. This manual includes
information on operating the following Airnet II models:
•301
•501, 501A, 510, and 510XR
•510s and 510s XR (stainless steel enclosure models)
For ease in understanding, this entire group of Airnet II models is referred in the
remainder of this document as Airnet II particle sensors. When a reference is given that
ONLY pertains to one or more models in this set, that specific model (or models) is
referenced.
An automated laser power control has been implemented that automatically shuts off
the laser power after 10 seconds of continuous bad flow. The laser power is restored
after 10 seconds of continuous good flow.
Airnet II particle sensors communicate by means of Ethernet with Facility Pro and
Facility Net1, monitoring system and software packages that store and display particle
data and allows the user to control the Airnet II.
Airnet II models also have the ability to communicate via Modbus TCP for an easier
integration to any third party system.
Airnet II models, except the stainless steel enclosed version, also have the option of
adding a 4-20 mA output board that can send a 4-20 mA signal which can be
customized for 4-20 mA-capable data systems.
1. This manual references Facility Net when discussing the software used to control these Airnet II
particle sensors. However, you can use either Facility Net or Pharmaceutical Net wherever this
reference is noted.

Class I Laser Product
The Airnet II particle sensors are Class 1 laser products.
Airnet II 510XR and 510s XR
The variant optical block components of the Airnet II 510XR and 510s XR particle
sensors are coated with a special Teflon®lining that allows them to withstand
environments that standard particle sensors cannot.
These environments are non-condensing and potentially corrosive or oxidizing to
other standard model Airnet or Airnet II particle sensors. Tests performed at the
Boulder factory allow Particle Measuring Systems to define environments where you
can use the Airnet II 510XR and 510s XR particle sensors.
WARNING
This instrument is a Class 1 laser product.aUse of controls, adjustments, or
performance of procedures other than those specified here may result in
hazardous radiation exposure.

CAUTION
When using the Airnet II 510XR or 510s XR particle sensors, it is important to
verify with Particle Measuring Systems that the unit can be used safely under
specific site conditions. Failure to verify this shall automatically void the
warranty.

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.
Bottom
Airnet II 301, 501, 501A, 510, and 510XR
(Polycarbonate enclosure version):
The bottom of the Airnet II unit contains four tapped-thread fittings that match the
countersunk screw holes on three of the four mounting brackets. These brackets are
used to mount the Airnet II to vertical or horizontal surfaces.
Airnet II 510s, and 510s XR
(Stainless steel enclosure version):
•The bottom of the Airnet II Stainless Steel enclosure version unit contains a dedicated
single thread fitting that match the countersunk screw holes of the dedicate wall
mounting stainless steel bracket (provided with the Airnet II 510s and 510s XR).

Instrument Connections
Airnet II 301, 501, 501A, 510, and 510XR
(Polycarbonate enclosure version):
All connectors are found on the back of the unit’s chassis, including:
• Electrical Power – Power can be provided through the 24 VDC power connector
(see Figure 2-6 on page 2-7) or though the Ethenet connection if Power over
Ethernet (PoE) is being utilized.
• Ethernet – The UTP Ethernet connector allows the unit to communicate with
Facility Net by connecting an Ethernet cable from the particle sensor to the
Ethernet hub.
•Modbus is also communicated via this connection when it is configured.
•When connected to a router that provides PoE the Ethernet connection will
power the system also.
• RS-232 – The RS-232 RJ-11 jack is used for configuring the unit and performing
limited diagnostics.
• Vacuum Source – The barbed fitting allows a source of house vacuum (>12in. Hg
for 510/510XR units and > 11 in. Hg for 301 and 501/501A units) to be supplied to
the unit.
• Calibration – A BNC connector is available for calibrations only and is not used for
system operation.
• Optional 4-20 mA Output – The six-pin Molex® connector outputs a scaled 4-20
mA signal that transmits the following:
•Channel 1 and 2 particle counts
•Instrument status messages
NOTE: If any modifications are made to the factory connector, make sure to verify the
24 VDC and GND lines before connection to the Airnet II unit.
NOTE: For best results, use a CAT 5 UTP cable. If PoE is used, you must use a shielded
CAT 5 UTP cable or ground the unit locally.
NOTE: Airnet II 301, 501, 501A, 510, and 510XR connection is a 1/4 inch tubing
connection.

Ethernet connector – For data transferring and power over Ethernet powering (PoE).
•Ethernet - The UTP Ethernet connector allows the unit to communicate with
FacilityPro and Facility Net by connecting an Ethernet cable from the particle
sensor to the Ethernet hub.
•Modbus is also communicated via this connection when it is configured.
•The instrument must be connected to a dedicated Ethernet switch that provides
PoE in order to provide the necessary power to the system.
