7�4�2 Signaling gear ratio
The number of rotations required to cover the whole travel must be known. For the required set-
ting of the signaling gear, refer to the "Signaling gear setting" table below. Intermediate values are
rounded up to the next incremental value (e.g. for 30 rev/stroke, the incremental value 36 has to
be set).
If an additional gear was set in the “Additional gear“ menu („7.2 Additional gear“ on page 36) , the
rmwarewillcalculatethesignalinggearsetting.
Setting the amount of the stroke at the additional gear output in the display is therefore required.
Depending on the additional gear, the following setting units are displayed:
– Actuator without or with rotary gearbox = rev./stroke,
– Actuator with connected linear thrust unit = mm/stroke,
– Acutator with connected part-turn gearbox = degrees [°].
The valve maker can also provide the data (number of revolutions for the entire travel).
If the number of revolutions per stroke is not known, because, for example, the actuator is to be
operated on an available "old" valve, operate the actuator over the whole travel and note the num-
ber of revolutions of the output drive shaft.
If the output shaft cannot be observed, proceed according to the descriptions of the following
chapter "Procedures for end position adjustment" and heed the information in the display under
"Help" on the signaling gear and proceed accordingly.
The table shows possible signaling gear setting for actuators without additional gears.
