11.7 Measuring the transit time
Risk of injury due to the actuator stem extending or retracting.
Do not touch or block the actuator stem.
The process is disturbed by the movement of the actuator stem.
Do not perform the initialization while the process is running. First isolate the plant by closing
the shut-off valves.
During transit time measurement, the actuator stem moves from its current position to the 0%
end position. Starting from the 0% end position, the actuator stem moves to the 100% end
position and back again to the 0% end position. The transit time is measured during the up
and down strokes and the average transit time calculated.
After the measurement is completed, the actuator returns to operating mode last used.
The 0% and 100% end positions depend on the operating direction used (see section9.3).

12 Communication level
In the communication level, details and possible settings for the actuator interfaces are dis-
played. Codes of the communication level have an 'A' prex to identify them. All the param-
eters of the communication level are listed in sectionFig.22 on page65.
