VP-80/VP-80 E
108
Trigger Level e.g. 2 V
Trigger level from
which triggering
occurs.
Vib.
Threshold
e.g. 8 mm/s
A vibration reference
limit which is displayed
in the bar graph and in
the polar plots. If the
value is exceeded, the
bar graphs or vector
arrows are displayed
in red.
Solution
Standard; 1-2
Plane with Pro-
gnosis
Standard balancing
solution or 1-2 plane
with prognosis,
allowing two balan-
cing problems to be
solved:
A)
1-plane balancing with measurement
at both bearings!
In this balancing process the correction
weight of plane A is calculated after the
initial run and trial run A. The residual vib-
ration of plane 1 and plane 2 is predicted
by the VIBROPORT 80.
B)
2-plane balancing with prognosis!
In this balancing process the correction
weight of plane A is calculated after the
initial run and trial run A. The residual vib-
ration of plane 1 and plane 2 is predicted
by the VIBROPORT 80. If the predicted
residual vibration is adequate, trial run B
can be omitted.
If the predicted residual vibration is inade-
quate, the balancing process can be con-
tinued with trial run B.
