Rice Lake BCi Belt Scale - Installation & Operation Manual Version 2.00 - Manual (Page 28)

22 BCi Installation & Operation Manual
The scale frame should be shimmed to match the weigh idler to the plane drawn by the alignment strings.
Figure 2-15. Shim Carriage if Needed
Recheck the level of the scale carriage and weigh idler.
The other idlers in the scale area should be shimmed to match the alignment strings. The finished aligned scale
area idlers should be equally spaced, level, and in a plane 1/4" higher than the adjacent idlers on the conveyor.
2.5 Speed Sensor Installation
The installation of the speed sensor will vary based upon accessibility to the tail roller, belt speed and distance
from the electronic integrator (BCi).
There are a variety of scenarios that can be used to install the speed sensor depending on accessibility. The
following steps go through various types of speed sensor installations but individual applications vary for each
job.
Encoder Speed Sensor Located on the Tail Pulley or Live Shaft Roller
1. Drill and tap a 3/8" hole centered on the tail roll shaft.
2. Prepare a mounting stud by removing the head of 3/8" x 1 1/2" bolt.
3. Thread the mounting stud into the tail roll shaft.
4. Install the 3/8" to 10mm encoder coupling to the mounting stud.
5. Install the encoder to the coupling.
6. Fabricate a mounting bracket to support the encoder.
Proximity Sensor Located on Idler Pulley
1. Measure the diameter of the idler to be used for the speed sensor.
2. Determine the number of targets to give a pulse a minimum of every 4" of travel.
3. Install steel targets equal around the idler.
4. Mount the proximity sensor within 1/4" of the targets.
