Installation instructions for standard cylinder
typeĂDNCI−...
ć Any mounting position is permitted (horizontal, vertical or
diagonal)
· Note that in conjunction with the SPC200, the complete
stroke of the drive must not be used.
Permitted work stroke = stroke length minus stroke
reduction
On each side of the drive positioning must not take place in
the range of the stroke reduction (see also chapter 3.4).
ć The best possible positioning behaviour can be
achieved if you use only 80 % of the stroke length of
the drive, symmetrically to the two end positions.
ć If demands placed on the positioning behaviour are
only slight, observe at least the following stroke reĆ
ductions in both end positions:
Piston j [mm] 32 40 50 63
Stroke reduction per end position [mm] 10 10 15 15
· Recommendation: Limit the movement range by means of
shock absorbers. In this way you can avoid damage in the
event of operating and system faults.
· Arrange the tubing between the valve (MPYE−5−...) and the
drive (DNCI−...) symmetrically and as short as possible.
Maximum tubing length = cylinder stroke length + 50 mm.
· Lubricate the external guide at suitable maintenance inĆ
tervals (be sure to note manufacturer specifications).
· Use only fastening elements which can permanently resist
the acceleration forces.
