5-8 EB 8332-1 EN
Installation
Actuators with resistance transmitters
Parts from the retrot kit (see Fig.5-5 on
page 5-5) are required. Intermediate gear
(1), spindle gear (2) and serrated ring (3)
from the basic unit (see Fig.5-5 on page
5-5) are already installed.
1. Unscrew screws on housing cover and
take the cover off the actuator.
2. Move the actuator stem to the end posi-
tion "actuator stem extended" or "actua-
tor stem retracted” (see the 'Operation'
section).
3. Continue as described in item 6 on
page5-6.
The basic unit is not required for the version
with resistance transmitter.
5.5.2 Installing the resistance
transmitters
An actuator board (available on request)
with the corresponding resistance transmit-
ters and gear wheels is required for a resis-
tancetransmitterretrot.
If the actuator does not have limit contacts,
parts from the retrot kit (see Fig.5-5 on
page 5-5) are required.

Note
Actuators without limit contacts
1. Unscrew fastening screws. Slide the actu-
ator board (12) from its guiding. Slightly
lift the board and continue pushing it fur-
ther towards the cable entry.
2. Clip the spindle gear (2) onto the sleeve
(13). Make sure the latch is properly en-
gaged in the groove of the sleeve. Slide
the intermediate gear (1) onto the spin-
dle 1 (11.1), mount the serrated ring (3)
and push it down as far as it will go.
3. The resistance transmitter gears (22 and
23)ttedwithserratedringsmustbeput
onto their shafts to correspond with the
rated travel of the valve. The rated travel
inscription'A'for60mmratedtravelor
'B'for30mmratedtravelmustbelegi-
blefromabove(seeFig.5-9).
4. Slide the actuator board (12) back into
its guiding. Make sure that all the gears
are properly engaged. Fasten the board
using screws.
