4.3 Preparation of the actuator
First the rotary adaptor is being prepared:
For attachment to a counter-clockwise or left turning
actuator secure the stud screw
4
on the left side of
the
“R”
in the threaded hole of the rotary adaptor
(see the big
“L”
marked drawing below).
For attachment to a clockwise or right turning actuator
secure the stud screw
4
on the right side of the
“L”
in
the threaded hole of the rotary adaptor (see the big
“R”
marked drawing below).
Than the feed back shaft
9
should be turned with the
bevelled side (flat part) according to the stud screw 4
(on the 0% position of the rotation indicator). Now screw
and tighten the bolt in the coupling against the flat part
of the feedback shaft (do not screw against the thread!).
Finally turn the feedback shaft in such a way that the
“R”
or the
“L”
of the coupling points to the arrow
10
of
the EP100 housing. Now place the rotary adaptor
3
with
two washers
5
on the feedback shaft
9
of the positioner
against the stop.
Note :
When the product temperature rises, than the
drive shaft
1
becomes longer. Therefore, the rotary
adaptor
3
must be mounted so that approx. 1 mm
(0.04 inch) of clearance results between the drive
shaft
1
and the rotary adaptor
3
. This is achieved by
placing an appropriate number of washers
5
on the
feedback shaft stub
9
before attaching the rotary
adaptor. Two washers should result in a clearance of 1
mm.
Beginning and end positions of the actuator drive shaft
1
and feedback shaft
9
are marked in the figures below
( the big
“L”
for the left-rotating actuator and the big
”R”
for the right-rotating actuator) by light-grey arrows
for the respective direction of rotation. The feedback
shaft is now in the normal position corresponding to the
failsafe position of the actuator. No shifting of feedback
shaft anymore!
4.4 Mounting of positioner
EP100 positioner and actuator are in failsafe position.
Attach the EP100 on the console in such a way that the
catch of coupling
3
is guided into the groove of shaft
1
.
Use bolt
2
to center and align the positioner to the
actuator. Be careful not to shift shafts
1
and
9
and that
both shafts are exactly flush. Fasten the EP100
positioner to the bracket by means of 4 lock washers
and 4 screws M6 x 12.
