Rev. B, 1/12 LOE Series Warranty and Warranty Restric ons APG warrants its products to be free from defects of material and workmanship and will, without charge, replace or repair any equipment found defec ve upon inspec on at its factory, provided the equipment has been returned, transporta on prepaid, within 24 months from date of shipment from factory.
LOE Series Rev. B, 1/12 • Understanding Ultrasonics Ultrasonic sensors use a transducer to transmit bursts of ultrasonic sound waves. Each burst contains a series of pulsed sound waves that emit in the shape of a cone, reflect off the target, and are detected by the sensor. The me required for the sound waves to travel to and from the target is converted into a distance measurement by the sensor. Ultrasonic sensing is affected by several factors including the target surface, distance, size, and angle.
Rev. B, 1/12 LOE Series Angle The inclina on of the object’s surface in rela on to the sensor face will affect the strength of the reflected sound waves. Surfaces perpendicular to the sensor will reflect more signal directly back to the sensor. If a surface is more than a few degrees off perpendicular, enough of the signal will be reflected away from the sensor that the target will not be detected. Generally speaking, a target angle greater than 5 degrees off perpendicular will not be detected.
LOE Series Rev. B, 1/12 Installa on The LOE must be mounted in a loca on with an unobstructed column of air to the target. The beam-spread chart on the previous page can be used as a rough guide to determine the required diameter of the air column for ranges of 10 feet or less. A 3 to 4 foot diameter air column is typically sufficient even at the maximum range of the sensor. The sensor should be mounted to ensure the target does not come closer than the minimum sensing range (blanking distance).
Rev. B, 1/12 LOE Series Powering the LOE The LOE can be powered using a 48 V POE connec on or a standard 12-28 Vdc power supply. POE Wiring To Network Connection LAN LAN + DC POWER POE Power Injector 24V B A RS-485 GND Terminal inside housing supplies 24 Vdc to power attached Modbus devices when powering the LOE from a POE source.

Rev. B, 1/12 LOE Series Sensor Setup via DHCP (automa c IP configura on) Connect the LOE to a network that provides access to the internet, and apply power to the sensor. The COM LED should begin to flash once every 30 seconds, indica ng the DHCP is a emp ng to establish communica on with the web site. Once communica on is established, the COM LED will illuminated. NOTE: see Troubleshoo ng DHCP if COM LED con nues to flash from more than 2-3 minutes.
LOE Series Rev. B, 1/12 Chick the “Home” bu on again to enter the main page. The sensor parameters are described in the ensuing pages. Network Se ngs The Network Se ngs are provided for advanced users only and shouldn’t normally require changes. The LOE comes defaulted with DHCP enabled, meaning the sensor only requires access to internet and it will automa cally connect to the www.levelandflow.com website and configure its own Network Se ngs.
Rev. B, 1/12 LOE Series Security Se ngs The Security Se ngs allow the user to set the username and password required to access the sensor se ngs. The default Username is admin and the Password is password. Labels Allows the user to assign custom labels to the Main Display. Labels apply only to the internal webpage--labels on the www.levelandflow.com website must be set through the website. Basic Parameters Automation Products Group, Inc. APG...
LOE Series Rev. B, 1/12 Basic Parameters (con nued) Sensi vity Controls the level of amplifica on applied to the target signal. The sensi vity se ng is expressed as a percentage; 0 to 100%. When opera ng in Autosense mode, the Sensi vity se ng acts as an upper limit constraint (see Gain Control for details). Blanking Sets the distance, beginning at the sensor face, to the point where the sensor will begin looking for target signals. All targets closer than the blanking distance will be ignored.
Rev. B, 1/12 LOE Series Basic Parameters (con nued) Averaging Defines the number of target readings that will be averaged together. Each qualified sample (see Filter Window and Out of Range Samples below) is placed into a first-in, first-out (FIFO) buffer and averaged with previous samples to generate a steady output. A higher Averaging se ng will result in smoother readings, but will also result in slower the response me to rapid target changes. Window Sets the width of the target acceptance window.
LOE Series Rev. B, 1/12 Basic Parameters (con nued) Mul plier Sets the conversion Mul plier that will be applied to the sensor readings. The default is 1.000 (see note below) and typically does not need to be adjusted. However, since the speed of sound is not constant through all environments, the mul plier parameter allows the user to adjust for varia ons in atmosphere when maximum accuracy is required.
Rev. B, 1/12 LOE Series Trip Point Relay Control The standard version of the LOE comes equipped with two solid-state relay outputs (trip points), which can be programmed to perform one of several logic func ons. In addi on, the LOE can be configured to ini ate immediate email and/or text message alerts whenever either of the trip relays ac vates or deac vates (see Immediate Website Alarms for more informa on).
LOE Series Rev. B, 1/12 Trip Point Relay Control (con nued) Type 4 (Inclusive): ac vates when the target is within the trip window. This can be used for various presence detec on applica on. Type 5 (Hysteresis Far): When the target moves beyond the Trip Distance + Trip Window, the relay will ac vate and remain on un l the target moves closer than the Trip Distance. The relay will then deac vate and remain off un l the target once again moves beyond the Trip Distance + Trip Window.
