1.0 Introduction
or
The Survivor® 1700HE Weigh Module
Kit is ideally suited for light to medium
capacity micro-ingredient batching and
mixing in a variety of hostile environments, especially where moisture is present. The load cell is stainless steel and
hermetically sealed with an IP rating of
IP68 to provide superior corrosion, moisture ingress, and mechanical protection.
The RLHBB and RLHTO load cells are
each waterproof guaranteed and OIML
C3 certified (20kg-5,000kg) to offer the
ultimate in durability and accuracy in any environment.
An important feature of the Survivor 1700HE is that the load may
be checked in one of two directions. This allows positioning in
one of two orientations for proper checking.
Integral jacking/shipping bolts offer a means to remove the load
from the load cell for quick removal and replacement of a load
cell and worry-free transport. The load introduction mechanism
also isolates the load cell from side loads, overloads, and underloads. For reliability
and accuracy, the Survivor 1700HE is the perfect mounting assembly for light capacity weighing.
The 1700HE modules are available from 5-250kg (11-550lb) capacities using
RLHBB cantilever beam load cells. In capacities from 500-5,000kg (1,100-11,000lb),
the units use RLHTO single-ended shear-beam load cells.
The installation should be planned by a qualified structural engineer. Each installation
is unique, and this manual is meant to serve only as a general guideline for installation.
Manuals can be viewed or downloaded from the Rice Lake Weighing
Systems website at

2.1
Installation Guidelines for Compression Weighing Assemblies
1. The mounting surface for the base plate and top plate must be level. After installation, the top and bottom plates must be level within ±0.5°. If the mounting surfaces are not level, then shims and/or grout may be used to level the mount.
If possible, check that the mount is level when the vessel is fully loaded because
excessive deflections in legs and supporting structures may cause additional side
forces that affect accuracy. Deflection of the mount’s top or base plate due to
loading should not exceed ±.5°. Reinforcement of legs or support structure may
be necessary. Vessels with long legs should have cross bracing applied between
adjacent legs to keep them from spreading under loads.
2. Compression mounting systems use 3, 4, or more mounts. More than eight mount
systems should be avoided as even weight distribution becomes extremely difficult to achieve. The load on each mount assembly should vary by no more than
20%. During installation, add shims where necessary to achieve correct load distribution.
3. If the actual load cel ls are used during installation of the weighing assembly,
extreme care must be taken to prevent overload damage. A tank or hopper weighing several tons can exert huge forces when dropped only a fraction of an inch.
The 1700HE series weigh modules incorporate a unique jacking bolt assembly
that should be used to remove the load from the cells during installation.
4. It is cruc ial that all piping or conduit
be horizontal and flexible. If flexible
piping is not used, make sure the distance from the vessel to the first pipe
support is 20-30 times the pipe diameter. For details, see our Weigh Mod-
ules & Vessel Weighing Systems
manual, PN 43918. In smaller, lower
capacity tanks and hoppers, isolating
the resultant forces becomes
extremely critical.
5. Load cells should not be installed in
the mounts until all welding is completed. The heat generated by welding current passing through a load cell can
damage the adhesive holding the strain gauge to the body. If possible, remove the
load cell when welding using the jacking/shipping bolts to mainta in fi nal height.
If welding is unavoidable after load cell installation, connect the ground in such a
way that the current does not flow through the load cell. For example, if welding
on the mount top plate, the ground must be connected to the vessel, not to the
mount base or support structure. Also, protect the load cell and cable from weld
splatter.
The arrow on the load cell should point in the direction of the load.
6. All support points should be equally stiff so that they deflect by the same amount
as the vessel is loaded.

The type of installation, vessel support structure, and the surface upon which the
mount is to be placed determines the method of locating, attaching, and assembling
the 1700HE weigh module. Carefully consider three areas that commonly cause accuracy problems:
• Are the supporting legs adequately braced so they will not spread when the
system is fully loaded?
• Does the supporting structure have the necessary strength to prevent excessive
deflection when the system is fully loaded?
Is there attached equipment such as skirting, venting, or piping which is likely to
•
cause binding or lack of flexibility?

After considering any areas that may cause accuracy problems, follow these installation
ABC D
Note
or
steps.
1. Determine where to position the mount and in which direction it should be oriented. The preferred mounting orientation for single ended beams is with the longitudinal axis of the load cell pointing toward the center of the vessel in circular
mounting configurations as illustrated in A and B in Figure 2-1.
Figure 2-1. Load Cell Orientation
Mounting configurations for square and rectangular vessels are shown in D an C
in Figure 2-1. For rectangular vessels, the load cell’s longitudinal axis should be
aligned along the vessel’s longest dimension as shown in Figure 4. In any application where a recurring side force is present in one direction, such as in a conveyor belt or roller platform, the longitudinal axis of the load cell should align
with that force.
The load may be checked in one of two directions. Make sure the top
plate moves in the proper direction (see step 2).
2. To assemble each module, remove the load cell bolts, position the load cell, and
pass the load cell bolts through the load cell and the load cell spacer, and thread
them into the base plate. Lift the top plate (do not loosen the retaining bolts) and
place the load button into the load hole of the load cell. Rest the top plate on the
load button. Verify that the retaining bolts do not protrude above the plane of the
top plate. Adjust if necessary.
During installation or transport, the jacking nuts may be used to isolate the top
plate from the load cell to avoid any damage to the load cell.
The load may be checked in one of two directions. To use the
alternate checking feature, lift the top plate clear of the load
button, turn the load button 90°, and restore the top plate to its
original position.
3. Lift and block the vessel to the same height as the assembled
mounts.
Use the jacking nuts to fully raise the top plate, automatically ensuring correct align-
4.
ment of the top plate and base plate during installation.
5. Remove the block from one support point and slide a mount into position.
6. If the mount is bein g fit ted under the leg of a vessel, verify that the leg’s center
line passes through the center of the load button.

7. Attach the top plate by bolting. Do not fully tighten as shimming may be

threads. The threads in the top plate of the 500-5000kg modules are 3/4”10 N.C. threads.
8. Repeat steps 4, 5, and 6 for the remaining mounts. The vessel should now be supported on the mounts alone.
9. If necessary, move the vessel to its final position. Verify that there is no initial
misalignment between the base plate and top plate. Verify that the load button is
centered in the top plate to allow equal travel on either side.
10. If the jacking nuts were used to isolate the load cell from the load, lower them to
the jacking spacers to lower the vessel to rest on the load cells.
11. Attach the base plates to the foundation using anchors for concrete or by bolting
or welding to a steel structure. Verify that the base plates are no more than ±.5°
out of level. Shim as necessary.
12. Check that the top plates are no more than ±.5° out of level. Shim if necessary
and fully tighten the bolts.
13. The load distribution can be checked by lifting the vessel sightly at each support
point in turn or, more accurately, by exciting each load cell in turn and measuring
the output with a voltmeter. The variation in load among the cells should be no
more than 20%. Shim if necessary.
14. Check that the two screws securing the load cell to the base plate are tight.

3.0 Load Cell Wiring
Drip Loop
1. Route the load cell cables so they will not be damaged or cut. Cable should not be
routed near heat sources greater than 150° F . Do not shorten any load cell cable.
The load cell is temperature compensated with the supplied length of cable. Cutting the cable will affect temperature compensation. Coil excess cable and protect it so it will not be mechanically damaged or be sitting in water.
2. Provide a drip loop in all cables so that water or other liquids will not run directly
down the cables onto either the load cells or the junction box. Attach load cell
cable to the dead structure, not the vessel.
3. If conduit protection is necessary against mechanical or rodent damage to the
load cell cables, use flexible conduit and conduit adapters at the load cells.
4. Connect cables for RLHBB, RLHTO, TEDEA 355, and TEDEA 3510 load cells
to the summing board in the junction box according to the guide shown below
and the labels on the terminal strips of the junction box. To verify the wiring
scheme, see the certification shipped with the load cell.
5. For better performance, use positive and negative remote sense lines if the wiring
run from the junction box to the indicator is longer than 25 feet.

5.0 Troubleshooting
If the system powers up and gives some type of stable digital readout that varies with
the load on the system, any system problems are probably caused by factors other
than the load cells. The load cells are often blamed for a malfunctioning system, but
90% of the time, the problem lies elsewhere. Look for mechanical causes for your
problem first.
If the system can be calibrated but doesn’t return to zero, loses calibration, or demonstrates non-linearity or non-repeatability, see the following chart for possible causes
and do the following checks.
1. Check load cell mount for debris restricting load cell movement or debris
between scale and structure.
2. Check that tank/ vessel and mounts are plumb, level, and square at critical areas.
3. Check all piping and cond uit for connections which restrict vessel movement.
Symptom Possible Cause
No return to zero Mechanical binding or debris in seals or under load cells
Non-linearity Thermal expansion or deflection under load causing binding
Non-repeatability Loose load cell mount
Lost calibration Out of level or plumb
Drifting readout Moisture in junction box, cables or load cells
May have lost system calibration
or side load.

4. If check rods are used, loosen all connections to finger tight only for testing.
5. Check load cel l cables for physi cal or water damage.
6. Check all electrical connections, especially in the junction box.
If the problem still is not found:
7. Check possi ble indicator malfunction by using a load cell simulator to input a
known good signal into the indicator.
8. Disconnect each load cell’s signal leads at the junction box and check individual
load cell outputs with a multimeter. Then check input/output impedances for
comparison with load cell manufacturer’s specifications.
If after all these checks the problem still cannot be isolated, reconnect all but one load
cell. Replace load cell with a load cell simulator. Alternate so that each load cell is
individually disconnected and replaced with a simulator. If there is a problem with a
particular load cell, the symptom should disappear when that load cell is disconnected
and replaced with simulator.
