MultiLoad II/ RCU II Explosion Proof Lite (EXL) Installation Guide - Part # 6070
Depending on the date of manufacture, the MultiLoad II may have one of three types of external switch
design. All can be sealed and locked to prevent access to Program Mode and to prevent changes of
Weights and Measures controlled parameters.
6.1.1.1
Magnetic Bolts Program / W&M Switches (current)
This design is the most current and can be found on all new units. This design consists of two separate
external magnetic bolts, one for Program Mode Access, and one for W&M change access. Program or
W&M access is achieved by removing the corresponding bolt. Each bolt has a small hole that can be
sealed with a wire and lead seal to detect unauthorized access. A single fold--down cover can be
locked to prevent bolt removal. The cover is marked “W&M” or “Program” adjacent to each bolt to
indicate the bolt function.

Type 3 Program / W&M Switch with Magnetic Bolts
Do not use a wrench to tighten the bolts. Insert the bolts and hand tighten only. Over-tightening
will damage the bolt assembly.
Two (2) Rotary Program / W&M Switches (obsolete)
This design consists of two separate external rotary switches: one for Program Mode Access, and one
for W&M Change Access. Each switch has an external fold-down cover that can be locked or sealed
with a wire and lead seal to prevent moving the switch into the active state. Each cover will also be
stamped as “W&M” or “Program” to indicate their respective function.
