Setting the operation mode

PVST: Stroke = stroke-con-

trolled PVST; based on travel

across a defined stroke (stroke

PVST) within a given time

(PVST monitoring time); can be

started in any valve position

(even outside the end position)

End position test = PVST based

on test when leaving the end

position within a defined time

(PVST travel time); Can only be

started from an end position
