8. Operation
All internal parameters, like required motor torque, actual position, functional status, etc., are being permanently
monitored during operation of the actuator PSF-Q-M. This ensures that the actuator positions with optimum
accuracy, and closes the valve always tightly.
Cut-off in end positions
Depending on the selected switch position S2-3/4/9, it is determined how the actuator approaches an end position.
When selecting "closing/opening with torque", the end position retraction of 3% is active in both directions, in which
case switch S2-1 has no function. In the operating modes "opening with swing angle", the actuator remains in the
open position that was set during automatic or manual calibration. The end position to be reached by torque is
always approached with a retraction of 3%.
9. Commissioning
•Open the cover (see 5.), mount the actuator on the valve (see 4.), connect the electric supply
(see 6.).
•Perform automatic (see 9.1) or manual commissioning (see 9.2).
•Close the cover.
9.1 Automatic commissioning
•Ensure secure connection between valve and actuator.
•To start the automatic commissioning push button B2 for minimum 7 seconds.
-Option 1: If adjusted “open with torque – close with torque”, the actuator will drive to the final open valve
position via torque, and back to the final closed valve position.
-Option 2: If adjusted “open with travel”, the actuator will store the open position with the torque end stop
(through adjusted end stop screw e.g.) and stop at the saved position during normal operation.
•After successful commissioning, the green LED is flashing 7 times.
•Push button B1 to return to normal operation.
•After successful commissioning check the found or adjusted rotation angle by comparing the set value and the
valve position.
•In case of unsuccessful commissioning the green LED is flashing quickly. Please check valve mounting.
•For commissioning, residual rotation angle of at least 2° in the end positions is required before the actuator has
reached its mechanical stop.
9.2 Manual commissioning
•Ensure secure connection between valve and actuator.
•To start the individual calibration push button B1 for minimum 7 seconds.
•For manual operation use push buttons B1 and B2 until the required open valve position is reached.
•Start commissioning of both positions and store them by simultaneously pushing the buttons B1 and B2 for
minimum 3 seconds.
•After successful commissioning, the green LED is flashing 7 times.
•Push button B1 to return to normal operation.
•Check the set rotation angle by specifying the setpoint and measuring the actual value.
•In case of unsuccessful commissioning the green LED is flashing quickly. Please check valve mounting.
•For commissioning, residual rotation angle of at least 2° in the end positions is required before the actuator has
reached its mechanical stop.
