7�5 End positions – non intrusive
The end positions must not be set according
toaspecicsequence.Adjustmentofend
position OPEN is described in the following.
End position CLOSED is adjusted accord-
ingly.
5. Selectendpositiontobesetrst(inour
exampleendpositionOPEN)(g.3,item1)
andconrm.
Display changes to end position adjustment
and you are requested to approach end posi-
tionOPEN(g.4).OPENdirectionisoffered
as operation direction. End position OPEN
symbol is shaded in orange (g.4,item.1).
If operation in the opposite direction is
desired, turn Drive Controller and set orange
selectionmarkedtosymbolCLOSED(g.4,
item 2).
Generally, the end position selected in
operationstep4istobeadjustedrst!
Furthermore, the display indicates the set
cut-off mode. In our example
■
End position CLOSED= torque-dependent
(item 3) and
■
End position OPEN = travel-dependent
(item 4).
6. Depending on whether the cut-off mode
for the end position is travel-dependent or
torque-dependent, select the following op-
eration sequence.
■
Travel dependent cut-off mode:
a) Heed valve position and approach end
position; press Drive Controller.
Operate the actuator until the valve has
reached the end position.*
The LED of the selected end position
asheswhiletheactuatorisoperated.
■
WhenpressingtheDriveControllerforashorttime(<3s),theactuatormovesaslong
astheDriveControllerispressed.Forlongeractivation(>3s),latchingstarts(display
shows ‘Latching active’) and the actuator moves until the Drive Controller is pressed
again.
■
If torque-dependent tripping occurred in travel-dependent cut-off mode, e.g. if the MOV
is sluggish, unfavorable torque characteristics or approaching of a mechanical stop,
"Torque dependent cut-off" is shown in the display.
b) Once the desired position has been
reached, press Drive Controller to stop
theactuator.Performpossiblene
adjustment by operation in the opposite
direction.

___________________________
* If the actuator has switched off automatically before reaching the end position, two causes are possible:
– Sluggish MOV or unfavorable torque curve. In this instance, abort process. Or
– Valve has reached mechanical stop. In this instance, return to desired end position.
