Your IRU should be installed in an area—indoors or outdoors—which meets the following
conditions:
بAmbient temperature between -20° to 140°F (-30° to 60°C).
بAmple space for maintenance and inspection
Additional care must be taken to ensure:
بThe sensor has a clear, perpendicular sound path to the surface being monitored.
بThe sensor is mounted away from tank or vessel walls and inlets.
بThe sound path is free from obstructions and as open as possible for the 9° off axis
beam pattern.
بThe sensor is tightened by hand to avoid cross-threading.
*Important: For user interface guide and sensor conguration see the full user manual.

Doc #9004254 Rev B
Each label comes with a full model number, a part number, and a serial number. The
model number for your IRU will look something like this:
The model number tells you exactly what you have. You can also call us with the model,
part, or the serial number and we can help you.
You’ll also nd all hazardous certication information on the label.
SAMPLE: IRU-6429-C6
The IRU series is APG’s line of general purpose ultrasonic sensors. With a choice of
operating ranges from just a few inches to as far as 50 feet, the IRU product line is
designed to t a wide range of industrial automation applications. It is certied for
installation in hazardous areas in the US and Canada by CSA for Class I, Division 2, Groups
C & D and Class I, Zones 2 environments.

Figure 5.1
All IRU sensors (excluding the IRU-6429S and IRU-9429S) are fully programmable using
an RST-3002 programming module. The RST-3002 is connected in series between the
sensor and its power source using the two 2-pin Phoenix connectors on the module
(See Figure 5.1). 15-28 VDC from the power source is connected to one 2-pin connector,
while the VDC + and DC Ground of the sensor is connected to the module through the
second 2-pin connector. When power is applied, the red LED between the Phoenix
connectors on the RST should illuminate and the sensor should start audibly “ticking”.
The operating parameters of the sensor can then be adjusted using the Windows-
based utility software (available at www.apgsensors.com/resources/product-resources/
software-downloads).

8General Care
Your level sensor is very low maintenance and will need little care as long as it was
installed correctly. However, in general, you should periodically inspect your IRU sensor
to ensure the sensor face is free of any buildup that might impede the function of
the sensor. If sediment or other foreign matter becomes trapped on the sensor face,
detection errors can occur.
If you need to remove the sensor, be sure to store it in a dry place at a temperature
between -40° and 180° F.
If your IRU ultrasonic level sensor needs repair, contact us via email, phone, or online
chat on our website. We will issue you an RMA number with instructions.
