About LoadMaxx Full and Dual Trailer Scales Installation Overview There are ive major components of the LoadMaxx scale that you will install: Trailer scale display • • Power interface and extension cables • Sensor interface and extension cables • Bracket Optional ComLink cable •...
Mounting the Scale There are three ways you can mount the trailer scale: • Flush mounted to the trailer frame itself • Using a van bracket • Using a frame rail bracket Choose the mounting method that will work the best with your trailer coniguration.
Mounting Flush to the Trailer A lush mounted scale is mounted directly to the side of the trailer. 1. Determine the best location to mount the scale. This should be a lat area of the trailer, thin enough to make drilling possible and accessible from both front and back.
Mounting with a Van Bracket Van Mounting Bracket The Van bracket is used mainly for van and refrigerated-type trailers. However, this bracket can be used on any surface-mounted installation. 1. Determine the best location to mount the scale. The bracket screws should be mounted on a ledge, and the scale itself should hang off the ledge with no obstacles blocking it.
Mounting With a Frame Rail Bracket Frame Rail Mounting Bracket A Frame Rail bracket is used primarily for lowboy or latbed-style trailers. However, you can use this bracket on any trailer frame rail. 1. Determine the best location to mount the scale on the frame rail.
Connecting Power to the Scale You can connect the LoadMaxx trailer scale to the trailer’s power either through the ABS brake harness or directly through the lighting junction box. Both methods are equally effective regardless of your trailer setup; choose the method that is most convenient.
toward the location where the scale is installed. If possible, route along an existing wiring harness. If the trailer has a sliding suspension you must use an existing wiring harness or umbilical to avoid damaging or breaking the cable. 6. Secure the cable loosely to the frame using zip ties. 7.
Installing Air Sensors Note: Avoid dropping sensors. Dropping can cause the sensors to fail immediately or shorten their lifespan. Note: This process will be repeated for both air sensors. 1. Locate the height control valves and the air bags they control. Full and dual trailers require two air sensors to be installed, so you will install one sensor on each height control valve.

5. Insert the airline into the top of the T itting. 6. Connect the airline itting to the side of the brass T itting and tighten securely. 7. Insert the air sensor into the airline itting. See diagram of the T itting and sensor set up below. 8.
Routing Cables Depending on whether you are installing LoadMaxx on a trailer with dual height control valves or on a full trailer, the process of routing sensor cables will differ slightly. Follow the instructions in the applicable section. Routing Sensor Cables for Dual HCVs 1.
Routing Sensor Cables for a Full Trailer 1. Find the two sensor cables provided in your scale kit and connect each to the air sensors you installed earlier. 2. Route the two cables along the axle and the frame of the trailer toward the location you chose earlier for the scale.
Checking for Correct Installation After you inish installing your LoadMaxx scale, follow the steps below to make sure you have installed the scale correctly. This will prevent the end user from running into issues when calibrating and using the scale. You should see 2 sensors in your A/D readings in Scale Diagnostics.
