Applications
The Load Ranger wheel weigh pads can be arranged to serve multiple applications. The adjustment from one scenario to another is made quickly and easily with the wireless and portability features of the Load Ranger system. This section highlights several of the arrangements available.
Wireless Setup
A wireless system allows for weighing with up to 16 connected wheel weigh pads per Ai-1 indicator. The wireless system is connected by following sections Section 1. through Section 3.
Typically wireless setup is configured for 2, 3, 4,5 or 6 pads.
Two Platform Applications
Two platform applications include weighing axles of the vehicle individually or trailers with only one axle.
Three Platform Applications
Three platform applications include weighing small planes, three-wheeled vehicles or trailers with a support pin.
Four Platform Applications
Four platform applications include weighing two-axle vehicles, trailers, containers, or other items with four support points.
Five Platform Applications
Five platform applications include weighing two-axle trailers with a support pin. When weighing both directions, a sixth platform can be used.
Six Platform Applications
Six platform applications include weighing three-axle vehicles or structures with six support points.
Wired Setup
A wired system allows for weighing up to four connected wheel weigh pads. The data communication port is located on the underside of the wheel weigh pad. For the RF-MD, the port is located at the handle end of the platform and is the port further from the edge. For the RF-WD and RF-XWD, the port is located at the end opposite of the platform handles.
Wired Setup Connection Procedure
- Assign channel numbers and ID numbers to the wheel weigh pads.
- Pair the Ai-1 indicator with the wheel weigh pads.
- Turn off the wheel weigh pads and the Ai-1 indicator.
- Connect RS-485 cables to the wheel weigh pads data communication ports.
- Connect free ends of each RS-485 cable to one of the Ai-1 indicator’s communication ports.
NOTE: The wheel weigh pads can be connected to any of the RS-485 ports on the Ai-1 indicator. The pad ID assigned within the wheel weigh pad dictates the scale number and it does not need to match the Ai-1 indicator channel number. - Turn on all of the wheel weigh pads.
- Turn on the Ai-1 indicator. briefly displays on wheel weigh pads (represents the assigned pad ID number). then displays on the wheel weigh pads and they are ready for use.
