OPERATION AND SERVICE OF
LC-WA LOW CAPACITY WEIGHING ASSEMBLIES
INTRODUCTION
EAGLE MICROSYSTEMS Weighing Assemblies provide the commercial and industrial user with
an easy to use, accurate and reliable method to weigh all types of hoppers, tanks, and scale
platforms. The LC - WA LOW CAPACITY WEIGHING ASSEMBLIES are self supporting and
require no stay rods.
MECHANICAL INSTALLATION
Install the Weigh Assemblies under the vessel's supports. Installation should be on a flat and level
surface. Assemblies can be shimmed so the load cells are roughly equal on each support.
Position the Weigh Assemblies so that there is no side loads or binding. LC - WA LOW CAPACITY
WEIGHING ASSEMBLIES can be mounted in any orientation with respect to the tank or hopper. It
is recommended that Weigh Assemblies be orientated so that they do not create a tripping
hazard.
The following are important installation considerations for hoppers and tanks.
1. The Weighing Assemblies should be level and parallel so that side loads and
bending moment loads are minimized.
2. The load on each assembly should be roughly equal.
3. The structure being weighed should not touch or rub against supporting structures.
4. The filling or emptying pipes should have flexible sections or run parallel to tank for a
length so that piping is decoupled from tank and will not affect system accuracy.
5. For lower capacity systems, the attachment of pipes and feed chutes to the tank is more
critical in relation to weighing errors.
ELECTRICAL CONNECTION OF ASSEMBLIES
1. Route the load cell cables to Summing J Box so that they will not be damaged or cut.
2. Connect the load cell cables to terminals on the Summing J Board.
3. Connect the 6 conductor hook-up cable from the Summing J Board to the load cell
terminal on the Weight Indicator.
IN CASE OF DIFFICULTY
A. The Tank seems to be weighing incorrectly:
1. Empty the tank and check the Associated Weight Indicator for a zero reading
when the tank is empty.
