How to Perform a Dynamic 2 Plane Procedure
Setup Options Specific to 2 Plane Balancing
Adjust the following settings on the
2-Plane
Balance Setup screen for a 2 plane
procedure:
Plane Setup
– (
Two-Plane (A=CH1&B=CH2)
or
Two-Plane (A&B=CH1)
), Select
whether you are using one or two sensors. Select
Two-Plane (A&B=CH1)
if you are
moving a single sensor between plane 1 and plane 2 to collect the measurements.
Select
Two-Plane (A=CH1&B=CH2)
to affix a sensor to each plane (using CH1 and
CH2 on the Microlog) and take both measurements simultaneously.
Note that other
setup fields adjust to display options specific to 2 plane balancing
Solution
– (
Dynamic
or
1-2 Plane with Prognosis
), Select
Dynamic
to compute two
correction weight solutions for a 2-plane balancing procedure. Select
1-2 Plane with
Prognosis
to start with a dynamic 2-plane balancing procedure, but after plane A’s trial
run, have the Microlog determine whether a single plane balancing procedure might be
a viable option, and if so, be able to convert from the 2-plane to a single plane
procedure for the rest of the balancing job.
Plane B Offset
– If necessary, you can enter plane B’s offset relative to plan A in
degrees. To have the ability to enter an offset,
Channel Setup
(on the device Setup
screen) must be set to
Individual
, and you must select
Component
for both
Plane A
Corr Type
and
Plane B Corr Type
. Enter the appropriate number of components for
each plane, as necessary, and then enter the
Plane B Offset
.
How to Perform a Dynamic 2 Plane Procedure
After setting up your balance measuring equipment, and setting the Microlog’s
balancing measurement parameters, you are ready to perform the dynamic 2 plane
balancing procedure.
To perform a dynamic 2 plane balancing procedure, the
2-Plane
Setup screen’s
Solution
field is set to
Dynamic
.
Perform the Reference Run
The 2 plane procedure is slightly different depending on whether
you are using one sensor or two. When usi
ng one sensor, Plane
1 and Plane 2 runs are performed sequentially, allowing the user
to move the sensor between the planes. Prompts indicate when
to move the sensor to the other plane.
When using two sensors,
it is assumed the sensor positions remain fixed and all Plane 1
and 2 runs occur simultaneously. The following instructions
detail the
two sensor procedure. When
you are using two
sensors, the Plane 1 and Plane 2 results display side-by-side on a
single screen.
To begin the dynamic 2 plane balancing procedure:
•
Start the machine
and bring it up to its steady running speed.
•
At the
2-Plane
Balance Setup screen, press the
Start
function button (or an
Enter / Fire button). The
Balancing
Summary
screen displays.
