Introduction

Thank you for purchasing an LPU-2428 ultrasonic sensor and RST-4001 programming module from APG. We

appreciate your business! Please take a few minutes to familiarize yourself with your LPU-2428, RST-4001,

and this manual.

The LPU-2428 loop-powered ultrasonic sensor provides a low-power, non-contact level measurement

solution rated for hazardous locations and suitable for harsh chemical environments. The RST-4001 oers

a two-line by eight-character LCD display and ve-button keypad or USB connection for programming your

sensor.

The default Application setting for the LPU-2428 is Distance, which will work in a wide variety of settings. The

LPU-2428 has several additional Application settings that can be congured to meet your needs.

Reading your label

Every APG instrument comes with a label that includes the instrument’s model number, part number, serial

number, and a wiring pinout table. Please ensure that the part number and pinout table on your label

match your order. The following electrical ratings and approvals are also listed on the label. Please refer to

the Certicate of Compliance at the back of this manual for further details.

IMPORTANT: Your LPU-2428 MUST be installed according to drawing 9002747 as

indicated above to meet Instrinsically Safe approvals. Faulty installation will invalidate all

safety approvals and ratings.

Chapter 2: Installation and Removal Procedures and Notes

Tools are not necessary for installing the LPU itself. If you are using a stand pipe to mount your LPU, you will

probably need tools to install the stand pipe, but not for the LPU.

• Tools Needed

• Installation Notes

• Mount your LPU sensor so that it has a clear, perpendicular sound path to the surface being moni-

tored. Your sensor should be mounted away from tank or vessel walls and inlets. See Figure 2.1.

• The sound path should be free from obstructions and as open as possible for the 9° o axis beam

pattern.

• If you are using a stand pipe, please see our guide to stand pipes on our website:

http://www.apgsensors.com/about-us/blog/how-to-install-a-stand-pipe.

Figure 2.1

NOTE: Do not mount the sensor where the beam will intersect objects such as ll

streams, pipes, ladder rungs, wall seams, or corrugated tank walls.

4Tel: 1/888/525-7300 • Fax: 1/435/753-7490 • www.apgsensors.com • [email protected]

• Mounting Instructions

For normal operation, connect the provided cable to your control system:

• Connect the red wire to +24 VDC.

• Connect the black wire to 4-20 mA input. Circuit load resistance + input resistence must be greater

than 150Ω. 249Ω is recommended for optimal signal tranmission.

• Refer to drawing 9002747 (page 42) for Intrinsically Safe installation.

• Refer to drawing 9002745 (page 43) for hazardous location installation.

For programming:

• Connect (+) terminal of RST-4001 to +24 VDC supply of sensor (red wire).

• Connect (-) terminal of RST-4001 to 4-20 mA signal from sensor (black wire).

• Ensure that load resistor is between RST-4001 and control network or PLC, rather than between sensor

and RST-4001. (See Figure 2.2)

• Electrical Installation

Mounting your LPU is easy if you follow a few simple steps:

• Never over-tighten the sensor.

• Always screw in your sensor by hand to avoid cross-threading. Thread failure can be a problem if you

damage threads by over-tightening them or by crossing threads.

IMPORTANT: Do not over tighten! The sensor should be threaded in only hand tight.

• Download the software zip le from http://apgsensors.com/support.

• Open the zip le.

• Choose “Install” from the options at the top of the zip le window.

• The installation process will prompt you as needed to complete the installation.

• The software will create and run from a folder in your start menu titled “APG”.

• Software Installation

• Ensure that power to the sensor is o.

• Disconnect the cable from the sensor.

• Remove the sensor and store it in a dry place, at a temperature between -40° F and 180° F.

• If the sensor was installed in a hazardous location, ensure that the cable will not be energized while the

sensor is disconnected.

• Removal Instructions

DANGER: Do not disconnect equipment installed in hazardous locations unless power

has been switched o or area is known to be non-hazardous.

IMPORTANT: The LPU-2428 software will only operate in a 32-bit Windows environ-

ment. It WILL NOT operate on a 64-bit Windows machine.

Your LPU-2428 ultrasonic sensor is very low maintenance and will need little care as long as it was installed

correctly. However, in general, you should:

• Avoid applications for which the sensor was not designed, such as extreme temperatures, contact with

incompatible corrosive chemicals and fumes, or other damaging environments.

• Inspect the threads whenever you remove the sensor from duty or change its location.

measure

This procedure uses targets at known distances to calibrate the sensor’s accuracy. A wall or other large, at

object is recommended for the long range target.

• Point the sensor at a target at a known distance near the maximum range of the sensor, 25’ for a single

solid object (See Figure 3.1).

• Adjust the Multiplier value until the distance reading on the sensor matches the actual measured dis-

tance to the target (See Figure 4.29).

• Point the sensor at a target near the minimum measurement range, 1’ plus any Blanking distance (See

Figure 3.2).

• Adjust the Oset value until the distance reading on the sensor matches the actual measured distance

to the target (See Figure 4.29).

• Repeat previous two steps until no further adjustment is required.

• Calibration

Figure 3.1 Figure 3.2

Should you have problems with your LPU-2428, here are some troubleshooting steps.

• Check the received signal strength (just to left of the three Help buttons in the lower right corner. See

Figure 4.32). If the signal strength is low, alternately increase Pulses and Sensitivity (Figure 4.30) until

the signal strength improves.

• Ensure Temperature Compensation (Figure 4.30) is turned on.

• Set the Gain Control to AutoSense (Figure 4.30).

• Ensure that Blanking (Figure 4.30) is accurately set to account for any unwanted targets between the

sensor and the closest acceptable target.

• Ensure that the LPU-2428 software is installed in a 32-bit Windows environment. Although the software

will install in a 64-bit environment, it will not operate.

• Trouble Shooting

IMPORTANT: The LPU-2428 software will only operate in a 32-bit Windows environ-

ment. It WILL NOT operate on a 64-bit Windows machine.
