SECTION 1.0 DESCRIPTION
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-H LOW CAPACITY WEIGHING ASSEMBLIES are self-supporting and require no stay
rods.
SECTION 2.0 PREPARAT ION FOR USE
2.1 RECEIVING INSPECTION
1. Upon receiving the assembly, carefully inspect the condition of the crate including the banding
and any protective covering used for shipping. Report any damage to the shipper and to
Eagle Microsystems.
2. Remove the assembly from crating and inspect for damage. Report any damage to the shipper
and to Eagle Microsystems.
3. In some cases, the assembly is shipped with fabreeka shock pads and, if ordered, optional upper
mounting plates removed and packaged separately. Verify that these items have been received and
save for final installation.
2.2 SHIPMENT
Should re-shipment of your assembly become necessary.
1. Use a strong, well built crate. The crate must be larger than the outer dimensions of the
assembly to protect it in shipping.
2. Make sure the hook-up cable is protected and secured in crate.
3. Use strong banding to secure assembly in shipment.
2.3 SITE SELECTION
1. Line power devices causing large inductive currents should not run off the same circuit as
the weigh system. Fluctuations in line voltage caused by such devices may result in display instability.
2. The hook-up cable to the read-out should not run close to other unshielded cables. Display
instability may result.
3. For best accuracy, a flat, level, and rigid surface is recommended to support the assemblies.
4. The area should be accessible for periodic cleaning.
2.4 INSTALLING
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 are no side loads or binding. LC–WA-H 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.
