13 Setting and operation
13.1 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 ac-
tuator 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 dir-
ectly from "OPEN" to "CLOSED". To this end, a dead
zone of 200 ms is integrated into the electronic sys-
tem, 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").
Electric shock by dangerous voltage!
▶ Risk of injury or death (if operating
voltage is higher than the 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.
