Safety
This section gives instructions to promote safe and proper handling of
the AeroTrak®+Remote Particle Counter.
I M P O R T A N T
There are no user-serviceable parts inside the instrument. Refer all
repair and maintenance to a qualified factory-authorized technician. All
maintenance and repair information in this manual is included for use by
a qualified factory-authorized technician.
Lase r Safet y
The TSI AeroTrak®+ Remote Particle Counter (particle counter) are
Class I laser-based instruments. During normal operation, you
WILL NOT be exposed to laser radiation.
The following precautions should be taken to avoid exposure to
hazardous radiation in the form of intense, focused, visible light.
Exposure to this light may cause blindness.
•DO NOT remove any parts from the particle counter unless you are
specifically told to do so in this manual.
•DO NOT remove the housing or covers. There are no user-
serviceable components inside the housing.
W A R N I N G
There are no user-serviceable parts inside this instrument. The
instrument should only be opened by TSI or a TSI approved
service technician.
W A R N I N G
If the Particle Counter is used in a manner not specified by the
manufacturer, the protection provided by the equipment may
be impaired.
W A R N I N G
The use of controls, adjustments, or procedures other than those
specified in this manual may result in exposure to hazardous
optical radiation.
When operated according to the manufacturer’s instruction, this device is
a Class I laser product as defined by U.S. Department of Health and
Human Services standards under the Radiation Control for Health and
Safety Act of 1968. A certification and identification label like the one
shown below is affixed to each instrument.

Safety ix
Warning
WARNING
Warning means unsafe use of the instrument could result in serious
injury or cause irrevocable damage to the instrument. Follow the
procedures prescribed in this manual to use the instrument safely.
Caution or Warning Symbols
The following symbols may accompany cautions and warnings to
indicate the nature and consequences of hazards:
Warns that uninsulated voltage within the instrument may
have sufficient magnitude to cause electric shock.
Therefore, it is dangerous to come into contact with any
part inside the instrument.
Warns that the instrument contains a laser and that
important information about its safe operation and
maintenance is included in the manual.
Warns that the instrument is susceptible to electro-static
dissipation (ESD) and ESD protection procedures should
be followed to avoid damage.
Indicates the connector is connected to earth ground and
cabinet ground.
Reusing and Recycling
As part of TSI Incorporated’s effort to have a minimal
negative impact on the communities in which its products

C H A P T E R 1
Introduction and
Unpacking
The AeroTrak®+ Remote Particle Counter (particle counter) is a compact
sensor that is appropriate for use in multiple locations in a large clean
room or critical environment to continuously monitor a process. The
sensors are very simple compared to a typical particle counter. They
have no display (other than several LED indicators) and can run with no
pump (central vacuum is used along with an integrated critical orifice) or
with an internal pump that is controlled to provide a constant volumetric
flow rate for 0.1 cfm (2.83 L/min) models.
Sensor data and particle counter information is communicated to an
external device via integrated Ethernet (TCP/IP), serial Modbus RTU
communications, a digital contact. 4-20 mA or wireless outputs are
available on select models. Oftentimes, this data is sent to a data logging
and reporting software, like TSI Incorporated’s Facility Monitoring
System Software.
The following table shows the remote particle counter models covered by
this manual.
* A denote 4-20 mA analog outputs
+ V denotes VHP resistant
* W denotes unit is capable of receiving the external wireless node

Installation and
Getting Started
This chapter describes the features, connections, and installation of the
AeroTrak®+ Remote Particle Counter.
Indi cator LEDs
The three LEDs on the front of the Remote Particle Counter provide
indication of the particle counter’s operation as described in the
table below.
Indicator
Status
Function
Status
Green
No errors are detected.
Red
Device is in a service alert from 1 or
more of the following conditions:
•Laser current error
•Laser scatter error
•Flow error
•Calibration error
•Ambient condition error
Flow
Yellow—solid
Device flow is good.
Yellow—flashing
Device has a flow error.
Off
No flow detected.
Sample
Blue—solid
Device is sampling and no particles
are detected.
Blue—blinking
Blinking rate is indicative (a guide) of
particle count activity in real time.
NOTE: The maximum blinking rate is
50 times per second.

2–2 AeroTrak®+ Remote Particle Counter Operation Manual
Elec trica l C on nec ti ons
The state-of-the art AeroTrak+ Remote Particle Counter supports
multiple communications and connectivity options. A brief description of
each of the connections is listed below.
Device Connections
•12-24 VDC/Relay Output Connector
•Ethernet Connector
•USB-C Connector
•AeroTrak+ Wi-Fi Node Operation
•4-20 mA Analog Output/Wireless Connector
12-24 VDC / Relay Connector
This connector can be used as either a 12–24 VDC power connection
when Power-Over-Ethernet (PoE+) is not available and as a relay
connection.
If used as a power connector, only a TSI-supplied 12 VDC power supply
(such as TSI model PSU-ARWP) should be used.

RELAY2 –Contact 2 for internal relay
If used as a relay, the alarm contact is used to indicate an alarm
condition. The alarm contact closure is normally open. The contact
closes upon an alarm, which could be a high particle alarm, a laser error,
a detector error, or a flow error, depending on the configuration of the
particle counter. The relay contact is rated for a 2A @ 30 VDC load. This
relay can be controlled by external software (i.e., FMS) and is configured
on the Configuration Utility.
