3.05 Modular Scale Description, HY Models
The HY15 is different from our other scales in that it a modular design. It does not have a single
rigid frame that an idler can be mounted on before scale installation. Instead it is a left and right
hand module that needs to be mounted on the conveyor structure and then the idler is mounted
between the modules. An HY15 is supplied with the components shown below.
An HY15 scale can be mounted in series creating a dual idler scale, an HY25. An HY25 would
include a second scale that would be identical to the first, but with out the signal conditioner
enclosure. See XXX for mechanical drawings of the HY15 and HY25.
3.06 Idler Preparation, HY Models
After finding a suitable location for the scale, reduce the conveyor belt tension. Raise the belt so
it is supported at least one foot above the idler where the scale will be located and also one foot
above the two idlers before and after the scale. Note, if you are installing a dual-idler scale
(model HY25), follow the same instructions as for the single-idler scale (model HY15) and just
repeat the instructions for both idlers.
DO NOT WELD ON OR NEAR THE SCALE!!!
1) Mark the center of each roller on the scale idler, two idlers before the scale, and two after (see
below).
2) Remove the idler where the scale will be located--this will be used as the weigh idler.
3) Weld a reinforcement gusset in each corner of the weigh idler.
4) Remove the weigh idler's factory mounting pads.
5) Paint the weigh idler for corrosion prevention.
