How To Read Your Label
2
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:
 SAMPLE: IRU-6429-C6
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 find all hazardous certification information on the label.

Installation Guidelines
4
Your IRU should be installed in an area—indoors or outdoors—which meets the following
conditions:
‫ب‬
Ambient temperature between -20° to 140°F (-30° to 60°C).
‫ب‬
Ample space for maintenance and inspection
Additional care must be taken to ensure:
‫ب‬
The sensor has a clear, perpendicular sound path to the surface being monitored.
‫ب‬
The sensor is mounted away from tank or vessel walls and inlets.
‫ب‬
The sound path is free from obstructions and as open as possible for the 9° off axis
beam pattern.
‫ب‬
The sensor is tightened by hand to avoid cross-threading.
*Important: For user interface guide and sensor configuration see the full user manual.
 IMPORTANT: Refer to section 10 for Hazardous Location Wiring.

RST-3002 Programming Module Wiring

Sensor
DC Ground
Sensor
+24 VDC
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
software-downloads).
