DANGER
On the side of the actuator there is a blanking cover for the
manual override. The crank handle for manual override is loc-
ated on the base of the actuator. Actuation of the manual
override additionally actuates a switch that shuts off power to
the actuator.
Example: Actuator version 2070
If manual override is required, take the following steps:
1. Unscrew the blanking cover using a screw driver.
2. Insert crank handle and actuate the actuator by hand.
Crank into the desired valve position (in the direction indic-
ated on label):

16.2.3 Setting the end positions
The GEMÜ 9468 motorized actuator is delivered in its open
position.
The "OPEN" and "CLOSED" end positions are set using the
limit switch 4. These are actuated using the lever 9 and can
be adjusted by undoing the two screws (see chapter "Product
description").
Destruction of the actuator!
▶ Do not move the right limit switch too far to the right and
the left limit switch too far to the left, otherwise the actu-
ator will continue running in the end position (i.e. the limit
switch cannot be actuated by the lever and the actuator
continues to run).
Designs 00, 0E, 0P:
- The actuator is not reversible, i.e. it must be stopped briefly
when switching over from "OPEN" to "CLOSED" or "CLOSED"
to "OPEN".
- For the above actuator types, overall height 1 applies (see
chapter "Dimensions").
