5.5.2 Installing the resistance
transmitters
An actuator board with the corresponding
resistance transmitters and gear wheels is re-
quired for a resistance transmitter retrofit.
Which actuator board is to be used depends
on the actuator type designation as well as
the power supply and transit time specifica -
tions (see Annex).
The retrofitting of the resistance transmitters
varies depending on whether the actuator is
fitted with limit contacts or not.
− Actuators without limit contacts:
see instructions below.
− Actuators with limit contacts:
see page 5-15.
Actuators without limit contacts
If the actuator does not have limit contacts,
an additional retrofit kit (see Fig. 5-10) is re -
quired.
1. Unscrew fastening screws. Slide the actu-
ator board (12) from its guiding to the
right. Slightly lift the board and continue
pushing it further towards the cable en-
try.
2. Clip the spindle gear (2) onto the sleeve
(13). Make sure the latch is properly en-
Note
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. Place the tension spring (4) onto the spin-
dle 3 (11.3), ensuring that the long wire
of the tension spring rests on the interme-
diate gear (1) and that the short wire of
the spring is located between spindle 3
(11.3) and spindle 4 (11.4). Mount the
shim (10) on spindle 2 (11.2). Place the
serrated ring (6) and push it down as far
as it will go.
4. The resistance transmitter gears (22 and
23) fitted with retaining rings must be put
onto their shafts to correspond with the
rated travel of the valve. The rated travel
inscription 'A' for 30 mm rated travel or
'B' for 15 mm rated travel must be legi
-
ble from above (see Fig. 5-16).
5. Slide the actuator board (12) into its
guiding. Make sure that the gears are
properly engaged. Fasten the board us-
ing screws.
