Balancing settings . In addition to the geometrical values, the Detector uses
69
the imbalance measured in the previous run in order to calculate the
suggested value. This is a reference or trim run for Plane 1 and for Plane 2 if
the test weight has been removed. The following applies for Plane 2: If the
weight has not been removed from trial run 1, the Detector takes the imbalance
from Trial run 1 in order to calculate the suggested weight value.
The Detector compares the calculated balance weights using a prescribed
safety limit that applies to the test weights. If the values calculated for the
weights exceed the safety limit, a warning message is displayed.
If the balancing measurement is performed using at least two sensors, after
each trial run for Plane 1 the Detector evaluates whether the number of
balancing planes should be modified. In the Balancing settings a value
69
greater than 0 must be entered for the balancing threshold (input field
Balancing OK at). If you adjust the plane number based on the Detector's
recommendation, the settings of the balancing measurement are copied along
with the reference run and trial run into a free measurement. This then allows
you to continue the balancing measurement. For the transmission to the
Trendline you must sort this measurement using the Wizard because the
115
measurement can no longer be assigned to the machine automatically.
If the coefficients determined after a trial run are used multiple times with
different balance weights for the trim runs, under some circumstances they
may no longer be meaningful. The Detector therefore checks the measured
result after each trim run using the calculated expected values and displays a
warning message if these values deviate from one another by more than 20 %.
If this is the case, you should first perform a new trial run.
As a general rule the amplitude units you specified in the Trendline program
settings 146 will be displayed during balancing. If a value in the current unit is
too large for the Detector display, the Detector will round this up automatically
to the next higher unit of measurement, for example, from 1050 m to 1.05 mm.
During balancing the internal amplifier is adapted to the input signal before the
start of each measuring procedure to optimize performance. However, if the
signal overmodulates during the measurement, the Detector displays a
message accordingly and reduces the amplification factor. This message
remains displayed if the input continues to overmodulate once the
amplification has been reduced. You will not be able to save the measurement
and must cancel it using the Esc button .
Starting the balancing measurement
Select the Balance menu item in the Detector.
Select the measuring point with the RFID Reader or manually (see "Selection
of measuring point 224 ").
