Introduction
Thank you for purchasing an LOE Ultrasonic Level Sensor and Web Enabled Controller from APG. We
appreciate your business! Please take a few minutes to familiarize yourself with your LOE and this manual.
The LOE Ultrasonic Level Sensor and Web Enabled Controller oers a wide degree of integrated, exible,
remote and local control and monitoring for your system. The LOE can control up to 10 APG Modbus
sensors--any combination of level, pressure, magnetostrictive and ultrasonic--and two input or output
relay terminals. All readings are available for control and monitoring via TCP/IP for local or remote network
access. The LOE also had exible power options: it can use either POE or an independent 12-28 VDC power
source.
Reading your label
Every APG controller comes with a label that includes the controller’s model number, part number, and
serial number. The LOE label also indicates the default IP address, subnet mask, and mac address. Please
ensure that the model number on your label matches your order.

Chapter 2: Installation and Removal Procedures and Notes
• Connection Notes
• Up to 10 Modbus sensors can be connected to the LOE in any combination.
• Output SSR’s are rated for 120V, 120mA max.
• Flat head screwdriver to remove knockouts for cables.
• If you are using a stand pipe to mount your LOE, you will probably need tools to install the stand pipe.
• For any attached Modbus sensors, please consult each sensor’s user manual for installation notes and
instructions.
• Tools Needed
• Use at head screwdriver to remove knockouts on either side of LOE housing.
• Insert included cable ttings in knockout holes.
• Connect any relays rst.
• Connect LOE to Ethernet/network.
• Connect independent 12-28 VDC supply if not using POE.
• Connect and set up one Modbus sensor at a time.
• Electrical Installation
IMPORTANT: Each Modbus sensor must be connected to the network individually and
assigned a unique Sensor Number before the next sensor can be added.
IMPORTANT: Multiple Modbus sensors added to the network simultaneously are all
assigned the same Modbus address/sensor number: 1. Sensors MUST be added to the
network individually.

• Installation Notes
• Mount your LOE 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
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.
• Mounting Instructions
Mounting your LOE 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.

Initial setup of the LOE and individual Modbus sensors is done via an embedded web server. The embedded
server can be accessed by using either the serial number or local IP address of the LOE and a web browser
(Internet Explorer, Chrome, Firefox, etc).
• Software Setup
The easier way to access the embedded web server is to type loe_xxx into a web browser on a computer
connected to the same local network as the LOE. xxx represents the numeric portion of the LOE’s serial
number. See Figures 2.2 and 2.3.
Accessing LOE Embedded Web Server via Serial Number
NOTE: If your web browser performs a web search for “loe_xxx” istead of accessing the
server, type “http://loe_xxx”.
Figure 2.2
Figure 2.3
NOTE: Port 6700 must be open on your local network for the LOE to connect.

Figure 2.6
On the Sensor Information screen you will see
the IP Address of the newly installed LOE. (See
Figure 2.6.)
Type the LOE’s IP address into your browser’s
address bar (See Figure 2.7).
Figure 2.7
Logging on to the LOE Embedded Web Server
The LOE’s embedded webpage should now be open, showing the Main Display page (See Figure 2.8). This
page lists the LOE, any Modbus sensors attached to the LOE, and displays each sensor’s current reading.
The LOE is displayed as sensor #11. The congured sensor number for each Modbus sensor will show as its
Sensor Number. Every new Modbus sensor defaults to sensor number 1.
IMPORTANT: Multiple Modbus sensors added to the network simultaneously are all
assigned the same sensor number: 1. Sensors must be added to the network individually.

Click on Home to bring up the Menu page (See Figure 2.9). The rst menu link clicked during each session
will prompt a User Name and Password login for the LOE (See Figure 2.10). The default User Name is admin,
and the default Password is password.

Assigning Modbus Senor Numbers
Click on RS-485 Network Settings to bring up the RS485 Settings page (See Figure 2.11). See section RS-485
Network Settings for a full description of each parameter in this menu (Page 38).

IMPORTANT: None of parameters in the RS485 Settings menu automatically update.
Each one must be manually congured.
• Disconnect power to the LOE rst.
• Disconnect network connection.
• Disconnect any sensors, relays, and switched inputs.
• Remove the LOE and store it in a dry place, at a temperature between -40° F and 180° F.
• Removal Instructions
NOTE: If you control the power to each Modbus sensor seperately, powering up a new
sensor after assigning a Modbus address to the previous sensor will allow you to assign
an address to the new sensor without leaving the RS845 Settings Menu.
Change Numb of Sensors On Line to reect the total number of Modbus sensors you will be connecting to
your LOE. Click Change (or press Enter) to send the new value to the LOE.
With Sensor Number to View set to 1 (for the latest sensor added to the Modbus network), set New Sensor
Number to the highest available number. Click Change (or press Enter) to send the new value to the LOE.
Repeat this process for each Modbus sensor as it is added to the network.

Chapter 3: Programming with Modbus TCP/IP
Using the LOE’s IP address, and port number 502, readings can be polled from the LOE for any attached
sensors via RS-485 Modbus commands. Up to 14 16-bit Input Registers, beginning with register 299, can be
polled with a single command. Below is a sample Modbus command illustrating the necessary syntax.
Example:
00 01 : Transaction Identier
00 00 : Protocol Identier
00 06 : Message Length (6 bytes to follow)
0B : The Reporting Unit Identier [sensor number] (0B hex = 11)
04 : The Function Code (04 = read Input Registers)
01 2E : The Data Address of the rst register requested. (12E hex + 1 = 303)
00 02 : The total number of registers requested. (read 2 registers, i.e. 303 to 304)
Byte order (hex values)
00 01 00 00 00 06 0B 04 01 2E 00 02
Notes:
• Reporting Unit indicates the sensor reading being polled from the LOE, in hex. 01 - 0A are for Modbus
sensors 1 - 10 attached to the LOE. 0B (i.e. sensor 11) reads the values from the LOE sensor (See Figure
2.8). Unused registers (i.e., those not associated to an attached sensor) will return zeros when polled.
• Data Address of registers, decimal to “hex minus 1” conversion:
Decimal Address Hex minus 1 Decimal Address Hex minus 1

300 12B 307 132

LOE Application Parameters
Figure 4.3
The Application Parameters menu congures the application-specic parameters applied to the calculated
reading from the LOE sensor.
PARAMETER RANGE
Units 1 - feet
2 - inches
3 - meters
Units is used to select the units of measurement for distance or level applications. The units will also
determine the resolution of Basic and Application Parameters. The resolution is: feet 0.01, inches 0.1, and
meters 0.001.
PARAMETER RANGE
Decimal Place 0 - 3
Decimal Place determines the number of decimal places shown on the output reading (see Figure 4.1). As the
output reading is used for setting/evaluating Trip Distance and Window, the Decimal Place setting applies to
those parameters as well.
