Manual Mode; Mechanical Override - Samson TROVIS 5724-3 Mounting And Operating Instructions

Operation

8.4 Manual mode

The actuator stem can be moved mechani-
cally or alternatively electrically in the manu-
al level in TROVIS-VIEW (u EB 6661).
Note
A manual adjustment of the stem position
only makes sense when the power supply is
switched off as the stem position is deter-
mined by the actuator in closed-loop opera-
tion, meaning any manual adjustment would
be automatically corrected by the actuator.
