General Installation Notes
Request our installation drawings if doing the installation
yourself.
If several linked clamping units are mounted, make sure that the
flatness and height deviation of the locating surface from module
to module (based on a gauge of 200 mm) lies within 0.01 mm. The
interface position deviation must not exceed ±0.015 mm.
Due to redundancy, the clamping rings with positioning accuracy in
one direction (SRB) should be used for clamping systems that are
more than 160 mm apart or that do not show a positioning
tolerance of ±0.015 mm. For the clamping areas that are not
intended for alignment of the device or pallet, clamping rings with
centering clearance (SRC) can be used
(

NOTE
When connecting the quick-change pallet systems, ensure that it is
only possible to completely bleed the piston chambers via the air
bleed screws (item 24) during the locking process and opening
process. The relevant valves or shut-off valves should therefore be
equipped with load relief. This also applies to the turbo
connection. If the turbo connection is not used, it must be possible
to ventilate the relevant side of the piston.
When disconnecting, the relevant openings must be secured with
center plugs to prevent ingress of dirt or coolant. If several units
are activated via shared lines, feed lines with the following
minimum cross-sections must be used.
Number of modules min. nominal hose width
1 5 mm
2, 3 8 mm
4 10 mm
For bleeding the piston chamber "Clamping with turbo", the four
air bleed screws (item 24) located on the upper side must be
loosened by two turns. The piston chamber must be pressurized
until hydraulic fluid emerges at the four air bleed screws. Close the
four air bleed screws again under pressure.
In order to bleed the piston chamber "Open", the air bleed screw
(item 24) on the side of the module must be loosened by two
turns. Then pressurize the piston chamber until hydraulic fluid
emerges at the air bleed screw. Close the air bleed screw again
under pressure.
