Mass load (
8 )
• Mount the mass load so that it is free of play.
Warning
Lateral loads produce incorrect measured results and can
even damage the measuring system.
• Use an external guide for the work load in order to
prevent transverse loadings on the piston rod.
For possible moveable mass loads, see chapter 2. The tables
listed there contain all the combinations of drives, valves and
mass loads permitted for operation with the SPC11 type
SPC11-INC-... .
Fixed stops (
9 )
Caution
If the entire drive length is used without fixed stops, the
DNCI or DDPC internal damping discs (pneumatic cushion-
ing) will deform. This can cause faults.
• Fit the metal fixed stops in such a way that the internal
damping discs will not be stressed.
If the DNCI or DDPC is operated in conjunction with the
SPC11, external fixed stops will be required. By means of the
fixed stops, the end positions can be set as desired.
Please note
During the teach procedure and during operation, a work
load is pressed against the stops at a pressure up to the
level of the operating pressure. Make sure that the fixed
stops resist this pressure.
