The controller:
•Provides a status of current sampler operations to the site operator.
•Provides an interface for recording initial and final measurements of the filters during sample changes
to the site operator.
•Provides options for selecting sampling protocols.
•Keeps the current date and time.
•Switches the filter solenoids and pump relays on and off.
•Records pressure transducers measurements. A standard configuration has 3 transducers:
Barometric Pressure, One Vacuum per module, and temperature. Measurement is done once a
minute and averages are recorded on the CompactFlash memory card every 15 minutes. The
averages are also recorded whenever there is a power outage or the operator starts the sample
change.
•Records the solenoid valve number that is open.
•Downloads all the measurements to the removable CompactFlash memory card.

2.5.1 Cyclone and Inlet
The ambient air enters through a screened inlet on top of the stack. The screened inlet removes bugs,
rain, and particles larger than approximately 15 µm. The air stream then passes through a cyclone that
removes particles larger than 2.5 µm. The cyclone is located inside the module, as shown on the
previous page. The cyclone is 50% efficient at removing particles with aerodynamic diameters larger
than 2.5 m at the nominal flow rate of 22.0 Lpm. It is volumetric flow controlled using a mass flow
controller and corrections are made for temperature and barometric pressure variations. A temperature
probe is inserted in the inlet tee of the Module C. The temperature probe is situated in the air stream just
prior to the cyclone. The temperature is measured and the average temperature is recorded on the
CompactFlash memory card.
μ
2.5.2 Mass Flow Controller
The Mass Flow Controller is used to maintain a constant flow rate during a sampling period. It is located
within the Pump Enclosure, near the base of the stand. For service/removal instructions, see Section 9.5.
2.5.3 Filter Cassettes and Cartridges
The filter cassettes and cartridges are manufactured specifically for the URG-3000N sampler. They are
made of acetyl homopolymer with stainless steel screens. The two halves of the cassette snap together
and are sealed with an o-ring. A special tool is required to separate and assemble the two halves. The
individual cassettes are always installed in cartridges, with four cassettes per cartridge. Most cassettes
are secured in the cartridges by a snap ring and cannot be removed easily. Each cartridge has a center
hole and a small alignment hole. When the cartridge is placed on the cyclone manifold, alignment pins on
the manifold prevent the cartridge from being installed incorrectly.

3. Mass Flow Controller: The Mass Flow Controller is located on a bracket within the pump enclosure.
For brief information see Section 2.5.2 and for service instructions see Section 9.5
4. Power Terminal: Underneath the door shown in the photo are two power outlets. The top outlet is the
correct outlet for usage with the Pump. This outlet is controlled to power on and off the pump. The bottom
outlet is to be used for the optional Enclosure Heater. Note that the red lever is a dummy lever and does
not perform any function.
5. Pump: The URG-3000N utilizes a 120V pump that is seated in the pump enclosure as shown. It
mounts with four nuts from the bottom, and service details can be found in Section 9.6
6. (Optional) Enclosure Heater: The area with four small mounts on the wall of the pump enclosure is
shown to indicate where the optional Enclosure Heater would be located. This heater is available for
usage with the URG-3000N in colder environments. Installation instructions can be found in Section 9.7.

3.3 Assembling the URG-3000N
The following steps show how to properly attach all cables for the URG-3000N prior to operation. At the
end of the instructions, a wiring diagram is shown for reference. Additional steps must be taken if a
collocated Module C is being used.
3.3.1 Keypad & Memory Card
The Keypad has magnetic strips on the back, which allow it to sit in a holder as shown below. Directly
below the Keypad holder is a cord storage area and memory card slot. To attach the Keypad, drop the
cable through the cord storage area and pull the data jack through the slot in the bottom left as shown.
Plug this data jack into the designated jack on the controller, also shown below. Afterwards, insert a
compatible CompactFlash memory card into the slot.
3.3.2 Pump Relay Cable
On the side of the pump enclosure, the cable furthest to the left is the relay control, which is fixed at the
pump end. The relay cable leaving the pump should be connected to the controller, as shown below. A
close-up of where the pump relay connects is also shown.
17

3.3.3 Controller Cable
The second cable to be attached is the 20” 12-pin to 12-pin data cable that connects the Controller to the
Module C and Mass Flow Controller. Begin by inserting the single end of the data cable (without the mass
flow controller connector) to the Controller as shown. Then, plug the other 12-pin connector into the
Module C. The breakout cable on that end is connected to the Mass Flow Controller, which is the central
port on the side of the pump enclosure, as shown.
3.3.4 Air Line
The Air line is a 30” black cable with Colder fittings at each end. It connects to the Module C and then to
the pump enclosure as shown, on the far right.
18

3.3.5 Temperature Probe
The temperature probe is mounted in the bottom left of the Module C, in
the inlet tee. To install, make certain that the plug is inserted in the inlet
tee. Drop the cable out of the bottom of the Module C, and affix the
plastic disc in the hole. Plug the connector into the rear right of the
Controller. See the Wiring Diagram for more details.
3.3.6 (Optional) Collocated Module C
The optional Collocated Module C is installed exactly the same as the standard Module C. The only
differences is that (2) of the cables are much longer so that the Collocated Module C can be installed 1
meter (inlet to inlet) away from the Module C. See the wiring diagram below for details.
3.3.7 Bottom-View Wiring Diagram
The following diagram shows a bottom view of the modules for wiring. Cable lengths are not to scale.
These bottom views are as if the front of the Controller, Module C, or Collocated Module C are facing up.
Example: Take a Controller with the front facing you and you lie it on it’s back. The bottom view that you
would see is what is detailed below.
