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 unit 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.
Hold down Drive Controller for more than
3 s. The actuator automatically moves until
reaching the end position. (For 2SG7 and
2SQ7, continue with step 14.)
