7.2 Setting the volume restriction
Q
The volume restriction Q is used to adapt the
air delivery to the size of the actuator:
4
Actuators with a transit time < 1 s, e.g.
linear actuators with an effective area
smaller than 240 cm², require a re-
stricted air flow rate (MIN setting).
4
Actuators with a transit time
³
1 s do not
require the air flow rate to be restricted
(MAX setting).
Intermediate settings are not permitted.
Note: The positioner needs to be initialized
again after the position of the restriction has
been changed.
