1.0 Overview
Thank you for purchasing a Setra particle counter, the world’s smallest, remote particle
counter sensor available for measuring and monitoring particle counts in clean room and
controlled environments for the Aerospace, Life Science, Data Storage, IAQ and Industrial
Hygiene Markets.
This user manual will provide the detailed explanation and instructions for the proper use and
operation of this feature-rich particle counter.
The Setra particle counters provide a range of particle size measurement from 0.3 μm to 10.0
μm for both 0.1 and 1.0 CFM flow. These sensors allow for efcient particle counting with
high accuracy and resolution that meets ISO 21501-4 for the calibration of a particle sensor.
These particle counters are congured with 2 or 4 particle size channel versions. The output of
these sensors can be accessed through the use of external software, a PLC, SCADA or facility
monitoring system that communicates via MODBUS ASCII or RTU protocols over an RS-485
connection.

Careful consideration was given to our packing material to ensure that your Setra Particle
Counter will reach you in perfect condition. If the Instrument has been subject to excessive
handling during shipping, there may be visible damage to the shipping carton. In the event
of damage, keep the shipping container and packing material for the carrier’s inspection.
Carefully unpack the Instrument from its shipping container and inspect the contents for
damaged or missing items. If the Unit appears damaged or something is missing, contact
the carrier and Setra immediately. Please save the container and packing material in case you
must return the Instrument.
2.1 Registering your product
All Setra Systems 3000 Series Instruments are automatically registered upon sale for the warranty period
and tracked by Serial number.
2.2 Contacting Setra
To order accessories, receive technical assistance, report damaged or missing items from your shipment,
or get contact information for your nearest Setra authorized reseller, call +1-978-263-1400
2.3 Storing and shipping the instrument
If the unit needs to be packed and shipped for annual calibration or service, it is recommended to use the
original packing materials. If they are not available, please insure that the instrument is packaged in a box
that is sturdy and that the unit is well protected with proper packing materials to cushion and protect it from
harm during transit.
To store the instrument, place it in a box, under cover, in an environment as stated in our specications.
2.4 Power considerations and connecting to AC power
The Setra 3000 Series Instrument is powered from a customer provided external DC power source between
9 – 24 VDC.
2.5 Turing the unit on
The 3000 Series instruments are designed to operate as xed installed instruments, and automatically
power on when power is applied to the external power connector. The instrument can be powered down if
the power connection is removed.

2.6 Laser safety information
The Remote Particle Sensor is a Class 1 laser-based instrument.
• During normal operation, you will not be exposed to laser radiation.
• Precaution should be taken to avoid exposure to hazardous radiation in the form of intense, focused,
invisible light.
• Exposure to this light may cause blindness.
• Take these precautions:
• DO NOT remove any parts from the particle sensor unless you are specically told to do so in this
manual.
• DO NOT remove the housing or covers. There are no user-serviceable components inside the housing.
2.7 Electrostatic safety information
Please complete all service and maintenance work at a static-safe work station.
If you fail to do so, electrostatic discharge (ESD) may result in damaging electronic components. Please
consider the following for creating a static-safe work station:
• Make sure all the test instruments are earth-grounded.
• Use a resistor-isolated wrist strap as well as a grounded conductive table mat.
DANGER
Any use of controls, adjustments, or procedures other than those specied in this
manual may result in exposure to hazardous optical radiation.
WARNING !

3.2 Installation
Please follow the steps below to prepare the instrument.
1. Locate where instrument(s) are going to be mounted.
2. Attach the Optional Isokinetic Inlet Joint Tube to the top of the inlet.
3. Attach the Optional Isokinetic Inlet to Joint Tube.
4. Please refer to section 3.4 and 3.5 for communication and wiring details.
5. Attached the sensor to an external vacuum pump system with a tube at the bottom of the instrument.
Add a negative pressure gauge to the other end of the tube. If the pressure is more than -15 in.Hg
(-50kPa) vacuum. The flow rate of a 3000 series is controlled to maintain proper flow (There is a critical
orice inside of the unit, which controls the flow rate when the negative pressure is equal to our greater
than -15 in. Hg (-50kPa) vacuum. After checking the negative pressure, remove the negative pressure
gauge, and then attach the tube to the outlet on the bottom of the sensor.
There is flow sensor in the unit. When the flow value is below the target threshold (e.g. the tube is bent,
vacuum pump is not functioning, etc.), the sensor status register during sampling (see Modbus register
map) will indicate a flow error. The Modbus Last record flow rate register (see Modbus register map) can
be used to monitor flow rate.

3.6 Cautions during setup
1. Factory default address for the unit is 247. The default Baud Rate is 115200 bps, but the following baud
rates are possible: 9600, 14400, 57600 bps. Communication is 8 data bits, at least 1
2. The length of optional sampling tubing can have a length of up to 1 meter with an inside diameter of 5
or 6 mm. If longer or thinner tubing is used it could create head loss and reduce the flow rate. Please
select the tube made of antistatic materials and deploy as straight as possible.
4.0 Communication protocol
The remote particle sensor can be communicated with using the Modbus-RTU or Modbus- ASCII protocol.
Facility/Cleanroom Monitoring software can be used as the monitoring system. If you would like to use your
own monitoring system, please contact Setra Systems.

5.0 Maintenance/Calibration
• Please do not open the enclosure of the unit. If you need to open the enclosure, please contact Setra
Systems for consultation.
• ISO 21501-4 states that the recommended calibration interval of an LSAPC (light scattering airborne
particle counter) is one year or less. For calibration, please contact Setra Systems or an authorized
distributor.
• Please check the negative pressure at the tube (where it connects to the outlet of the unit) to ensure
that the vacuum pump is providing enough negative pressure to the unit. Section 3.3, line 5 for more
details.
• Before cleaning / disinfecting the environment, please turn off the unit, stop the vacuum pump, and
then put the included red cap on the inlet nozzle.
For cleaning (fumigation) please be sure to follow this procedure:
[Before fumigation]
1. Turn off the Power of the unit.
2. Turn off the vacuum pump.
3. Put the red inlet cap on the isokinetic probe to protect the optical block from the agent.
[After fumigation]
4. Please make sure the air ventilation is completed (If agent is left in the environment and gets into the
optical block, it will cause a malfunction).
5. Turn on vacuum pump and power.
