Adjusting the volume restriction Q
The volume restriction Q (see Fig. 17) serves to adapt the air output capacity to the size of
the actuator:
Actuators with a
transit time < 1 s
, e.g. linear actuators with an effective area smaller than
240 cm², require a restricted air flow rate.
Setting to MIN
Actuators with a
transit time ≥ 1 s
do not require the air flow rate to be restricted.
Setting to MAX
Additional points that apply concerning the volume restriction:
Î
Intermediate settings are not permitted.
Î
Re-initialize positioner after changing the volume restriction setting.
