3.1 Mechanical Installation - Linear Actua-
tors
The mounting set is used for mounting POSIFLEX positioners
on linear actuator which have mountings in accordance with
DIN IEC 534-6. All parts are made from stainless steel. The
mounting sets contain two different levers for different stroke
ranges:
1.
Stroke 10 - 65 mm
2. Stroke 65 - 100 mm
Mounting is possible for actuators with pillars, by using the
bracket (7) with the U-bolt (8). Or for actuators with a cast pad,
by direct fitting using the screw M8x20 (16) with washer M8
(17). The linear moving of actuator has to be converted into a
rotation of the shaft of positioner. The distance ”A” between
coupling bolt (6) and shaft of positioner is set with reference to
the table below. This distance is a function of stroke S. Pre-
setting the linkage with this distance ”A” enables the best range
setting to be achieved with only a small adjustment on the
positioners’ range setting. A spring (3); (5) in lever (2); (4)
eliminates play in the linkage.
3.1.1 Installation sequence
The following installation sequence is for a positioner with a
direct action (increasing signal opens the valve with rising
spindle.)
1. Insert lever (2); (4) at end of positioner shaft and fix it with
screw.
2. Check the standard interface of actuator and mount bracket
(7) at left side of actuator - at pillar or casting pad.
3. Choose the position of bracket (7) where lever (2); (4) is in a
horizontal position and the actuator is in mid stroke.
4. Position the coupling bolt (6) for a correct distance ”A”, with
reference to the table 3.2.
5. Fix coupling bolt with nut M6 (10).
6. Adjust positioner (zero, range, amplification).
7. Change setting of zero and range as required.
Note:
1. POSIFLEX positioners for linear applications are adjusted
for an angle of 40° as standard (see table above). For
different strokes i.e. 10mm or 100 mm (other angle!) reset
zero and range adjustment of F20.
2. Several parts, standard parts e.g., of mounting kit are
already pre-assembled for ease of assembly.
3. Using only one lever is possible in applications of F20 if the
relation of stroke and distance ”A” is not more than 1,0. To
use this type of assembly, please also order coupling bolt
ES (Part number 6.003618).
