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 oers 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.
