All internal parameters, like required motor torque, actual position, functional status, etc., are being permanently
monitored during operation of the actuator PSF. This ensures that the actuator positions with optimum accuracy, and
closes the valve always tightly.
Cut-off in end positions
Depending on the settings of S2-3/4/9 the actuator drives to a distinct position. When selecting “Close with
force/Open with force”, the shut-off minimum is active at 3% in both directions. In this case, the switch S2-1 has no
function. When using the function “Open with stroke” the actuator stops at the upper end position which was found
during automatic commissioning or which was manually set. The actuator drives to the lower end position by force at
a minimum shut-off window of 3%.
8.1 Split Range / Split range
Bei der Einstellung „Sollwert/Splitrange“ Schalterstellung S2-2/7/8 wird der Sollwert je in einen unteren oder oberen
Bereich aufgeteilt. Dadurch können mehrere Antriebe mit nur einem Sollwert-Signal angesteuert werden.
The setting “set value/splitrange” at S2-3/4/9 splits the set value into an upper and a lower range. Due to this
function multiple actuators can be controlled by only one set value signal.
Sollwert / Set value
Stellantrieb 1 / Actuator 1
Stellantrieb 2 / Actuator 2
