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
Blanking cover

override
Crank handle
for manual
override
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):
Actuator version 2070
Clockwise: Open
Anticlockwise: Closed
Actuator versions 4100, 4200, 6400
Clockwise: Closed
Anticlockwise: Open
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").
CAUTION
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 (see chapter "Functional versions"):
• 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").
Designs A0, AE, AP, E1, E2 (see chapter "Functional ver-
sions"):
• The actuator is reversible, i.e. it can be switched directly
from "OPEN" to "CLOSED". To this end, a dead zone of 200
ms is integrated into the electronic system, i.e. when
switching over, the actuator does not run for this time.
• Independent of the supply voltage, the OPEN/CLOSE control
is freely selectable via a mains supply of 24 V DC, 24 V AC
up to 250 V AC or operated directly via a PLC.
• An electronic current limitation limits the torque.
• For the above actuator types (except for code 2070), overall
height 2 applies (see chapter "Dimensions").
DANGER
Risk of electric shock
▶
Risk of injury or death (if operating
voltage is higher than safe extra low
voltage).
▶
Adjustments are made with the actu-
ator cover removed.
▶
Electric shock can cause severe burns
and fatal injury.
●
Always disconnect the product from
power supply!
●
Therefore, have all work performed
only by qualified electricians.
