3.2.1 Mountingsequence
Î Mounting parts and range spring: see
Table4/Table5.InstallationinFig.7.
Valvewithcastyoke
1. Screwtheplate(20)tothestemconnec-
tor of the actuator and plug stems using
the countersunk screws.
Usetheadditionalbracket(32)for2100
and2800cm²actuatorswith120mm
travel.
2. Removetherubberstopperfromthe
adapter housing and fasten the adapter
housing either on the left or right of the
NAMURribusingthehexagonhead
screwasshowninFig.6.
Valvewithrod-typeyoke
1. Screwtheplate(20)tothefollower
clamp of the plug stem.
2. Screwthestuds(29)intotheadapter
housing.
3. Place the adapter housing with the plate
(30)ontoeithertheleftorrightvalverod
andscrewtightusingthenut(31).Make
sure that the adapter housing is at the
correctheighttomountthelever(18)so
that it is in a horizontal position when
thevalveisatmid-travel.
4. Screwthepin(19)intothemiddlerowof
holesontheplate(20)andlockitinto
position over the correct lever marking (1
or2)asindicatedinTable6.
5. Clamptheclip(21)ontothelever(18).
Theclipmustbeclampedontothelever
(18)withtheopensidefacingdown-
ward when the positioner is attached
with the air connection at the front.
6. Attachthelever(18)includingclamping
plate(22)totheshaft(25),makingsure
thattheclipclaspsthepin(19).
3.2.2 Initialadjustmentof
travel
1. Movethevalveto50%travel.
2. Movetheshaft(25)intheadapterhous-
ingsothattheblackpointer(24)match-
es the cast marking on the adapter hous-
ing.
3. Fastentheclampingplate(22)inthispo-
sitionusingthescrew(23).
4. Screwthepin(27a)intothepositioner
lever on the side where the press nut is
located. Lock it in position with the hex
nutontheotherside,observingthe
mounting position A or B according to
Table6andFig.7.
5. Place the positioner on the adapter hous-
ing, taking into account the mounting di-
rection. Fasten it, making sure that the
pin(27a)restsagainstthebracket(28).
Thepinmustnotslipoutofthebracket
once installed.
6. Check whether the correct range spring
hasbeeninstalledaslistedinTable6.
Range spring 1 is installed as standard.
If necessary, replace it with range spring
2includedintheaccessoriesandxitat
theouterhook-inholes.
7. Performpositionersettingasdescribedin
section5.1.
