MWG position transmitter in actuator
The histogram show the percentage distribution of exceeded acceleration. Exceeding
of the acceleration limits preset in the factory is recorded in ten different frequency
ranges with 20 Hz each (0 – 20 Hz, ..., 180 – 200 Hz).
The histogram indicates the frequency range within which the actuator was exposed
to vibration for example (e.g. vibration with the pipeline). Impermissibly high or
persisting vibration can destroy components of the actuator.

MWG position transmitter in actuator
The torque scale is divided into the following segments for both directions
(OPEN/CLOSE):
from 0 – 30 %
from 30 – 110 % (8 segments with a width of 10 % each)
more than 110 %
During each operation, the counter of the segment corresponding to the currently
required torque will be incremented. The result is shown in a bar chart. The histogram
is cyclically saved once a minute, in case a change has occurred.
The motor running time-torque histogram indicates the actuator load during service
life.
