Balancing Extension Module Chapter 2
Specific differences exist between single and two-plane balancing measurement
field settings. Setup options specific to two-plane procedures are detailed below.
See Single Plane Balancing on page 26
section for all other settings that apply to
both single and two-plane balancing.
Set-up Options Specific to Two-plane Balancing
Adjust these settings on the Balance Setup screen for a two-plane procedure.
See Balance Extension Module Parameters on page 22
for descriptions.
1. Enter 2 for Num. of Planes to specify a two-plane balancing procedure.
Other setup fields may adjust to display options specific to two-plane
balancing.
2. Select whether or not you are using one or two transducers in the Num.
Transducers field.
• Select one if you are moving a single transducer between channel 1 and
channel 2 to collect the measurements.
• Select 2 to affix a transducer to each plane (using Connector A and
Connector 2 on the data collector) and take both measurements
simultaneously.
3. In the Solutions field, select whether or not you are using a Dynamic or
Static-Couple
• Select Dynamic to compute two correction weight solutions for a
two-plane balancing procedure.
• A Static-Couple option is available for situations where you wish to
compute three correction weights, one to correct the static unbalance,
and two to correct the couple unbalance (static-couple balancing).
See Static-couple Balancing on page 18
for more information about the
Static Couple parameter.
4. Select Plane 1/Plane 2 – When setting up two planes, the Balance - Setup
screen expands to include a section for Plane 2 settings.
• When two-plane balancing with one transducer, the Input Channel,
Coupling, Sensitivity, and Input Range are set on Plane 1 and apply to
both planes.
IMPORTANT
If using only one transducer, you must also specify the same input
channels for both Plane 1 and Plane 2 sections.
For two transducer balancing, you must also specify X and Y input
channels for Plane 1 and Plane 2 sections.
