Assembly instructions
The PSM 1 is affixed by means of screwed on plates (Fig. 14.10). You can choose between: 4x M Allen screws, from above
( .5 mm hole), . 4x M screws, from below (M thread). Spacings: see Sections (I) and (J). The surface must be clean and
level. The parallelism of the sleeve to the enclosure and/or screwed-on plates is achieved by means of two feather keys.
Alternatively, the PSM 1 can be pinned to the surface using 4 cylindrical pins (ø 4 mm).
Compressed air connections
There are three compressed air connections on the rear of the PSM 1 (Fig. 14.17): 1. compressed air motor connection (middle)
for hose, with an external diameter of 10 mm, . connections (right and left) for the prestroke and return stroke for the
hose with an external diameter of mm. Caution! When sizing the compressed air line, please ensure that the section
of the line is large enough so that there is always a pressure of 5-7 bar at the air inlet of the PSM21 when the motor is
running. The air consumption is 5.4 l/sec at .3 bar.
Lubrication
The motor and cylinder should be run with dry (DTP +3...+10°C), filtered (5 µm) and oiled air. You can find special and very
interesting information on the subject of „Lubricating compressed air tools and transmissions“ at [www.psm-muenchen.
de/psm_katalog/einzelstellenoeler_spl_ 007_10.pdf]. Caution! If you run the PSM21 free of oil, please make sure that
the bladed shutter is 6-8 times higher, for instance.
Stroke setting
The overall stroke consists of the fast stroke and the working stroke (Fig. 14.11). The stroke is set with two screw-components.
The screw-component ( , Fig. 14.12 and Fig. 14.13) is used to set the overall stroke. Caution! First unscrew stud screw
(51, Fig. 14.14). By means of the stud screw (13, Fig. 14.12 and Fig. 14.16) set the fast stroke and/or the retarded working stroke.
This adjusting screw has a Long-Lok ® thread-lock and must thus not be specially countered or secured. First tighten the
stud screw again (51, Fig. 14.14). Once the stroke settings have been completed, the „optional“ proximity switches (Fig. 14.18)
can be set up.
