Commissioning button
During automatic commissioning the actuator goes through the full programmed valve stroke / angle automatically.
Parameters specific to the valve are being measured and calculated values are permanently stored in the actuator.
At the same, set value and position feedback range are scaled.
To enable Automatic Commissioning, a mechanical stop is required in at least one end position (usually the closed
position) of the valve. This mechanical stop can be either given by design of the valve, or it may be adjusted by the
stop screws of the actuator (only when cut-off “by position automatically“ is programmed).
11.1.1 Adjusting the Mechanical Stop
Shown is the adjustment of a mechanical stop in closing direction for a valve closing clockwise.
.
Item 1: Allen screw for CLOSED position
Item 2: Allen screw for OPEN position
Item 3: protective caps
11.1.2 Commissioning Procedure
When adjusting a mechanical stop, drive the actuator only by
hand wheel, not electrically!
Figure 22: Adjusting the final position
Remove the cap (fig. 22, item 3) from the stop screw for CLOSED
position.
Unscrew the Allen screw by approx. five turns.
Drive actuator clockwise by hand wheel to close the valve.
Screw-in the Allen screw until a slight resistance is felt. (fig. 22; item 1)
Drive actuator counter-clockwise by hand wheel to open the valve.
Fig. 22, item 2 is the stop screw for OPEN position.
Screw back protective caps.
Figure 23: Commissioning button
Ensure that all mechanical and electrical
connections have been made properly. Switch on
power supply. Unscrew the side cap for the
actuator’s main cover and press the commissioning
button with an insulating pin for about 3 seconds.
Caution!
The actuator will now travel through the full valve
angle!
