What your truck scale is telling you it wants
I want to remain debris-free all year ’round!
It is vital that all dirt, mud, and debris is cleaned from around load cells and cable. In the winter months, if temps are cold enough, this debris freezes and will inhibit weighbridge movement leading to inaccurate weights or even load cell damage.
I want to be snug!
As seasonal temperatures change, so do end and side-to-side bumper checking adjustments. End bumpers should be adjusted to 3/16″ and side-to-side bumpers should be adjusted to 1/8″. End plates MUST be removed to check side bumpers; a visual underneath is not enough. Plus, while the end plate is removed cleaning around the load cells is a snap!
I want to be secure!
Inspect anti-rotation pins on rocker column load cells to be sure they are intact and not bending, or worn. B-TEK Scales LLC has new anti-rotation pins and hardware kits readily available.
I want to move!
Rocker column load cells should be removed periodically so that upper and lower receivers can be cleaned, greased, and inspected. If the lower receiver does not have a convex radius, it should be replaced.
I want to be sealed and dry!
Apply dielectric grease to load cell connectors, and be sure that connectors are tightened securely (hand tight plus ¼ turn on digital cells).
If junction boxes are opened, wipe clean all gasket mating surfaces and apply a thin film of grease to gasket surface to aid sealing. Replace desiccant bags and inspect circuit boards for corrosion.
I want to be grounded!
Check, clean, and coat all ground connections with oxidation-preventing grease. Ohm readings should be taken from several points in the system, any reading over 1 ohm is suspect. Grounding problems can cause drifting, weight repeating problems, as well as leave the system susceptible to surge/lightning damage.
