The displacement (deflection), in mm, displayed for each isolator is proportional to the load compression
of the isolator’s internal high-frequency elastomer mount. The table shows the corresponding load range
in lbs or kg based on range of deflection.

15) Isolator Load Re-Distribution Using the Internal Wedgemount
For a 3-isolator system
,
if the isolators are not properly loaded, their installation location
must be changed until each isolator is within the proper load range specified above. The
loading of the isolators should not be adjusted using the internal wedgemount
.
If proper loading cannot be achieved,
a different load capacity isolator may need to be
purchased to correct the problem.
•
Readings less than 2.2 mm may be an indication of an under-loaded isolator, whereas
readings greater than 4.5 may be an indication of an over-loaded isolator.
•
For proper loading, each isolator should have between 2.2 and 4.5mm deflection. If an
isolator is loaded outside of this range, follow the instructions in the following section to
re-distribute the load. If all isolators are out of this range, please contact TMC.
The controller should have been configured at the factory to the correct number of
isolators (2, 3 or 4). If not, (typically when the controller is shipped as a replacement)
the display may not show the correct number of readings. If this is the case, refer to the
Menu Driven Functions
in the Section 5 for instructions on how to configure the
controller for the correct number of isolators.
