Protection during commissioning and operation
Falling or violently ejected components
Falling and violently ejected components can cause serious injuries
and even death.
• Take suitable protective measures to secure the danger zone.
• Never step into the danger zone during operation.
• Before commissioning the machine or automated system,
check that the EMERGENCY STOP system is working.
Protection against dangerous movements
Unexpected movements
If the system still retains residual energy, serious injuries can be
caused while working on the product.
• Switch off the energy supply, ensure that no residual energy
remains and secure against inadvertent reactivation.
• Never rely solely on the response of the monitoring function to
avert danger. Until the installed monitors become effective, it
must be assumed that the drive movement is faulty, with its
action being dependent on the control unit and the current
operating condition of the drive. Perform maintenance work,
modifications, and attachments outside the danger zone
defined by the movement range.
• To avoid accidents and/or material damage, human access to
the movement range of the machine must be restricted. Apply
technical safety measures to limit/prevent accidental access for
people in this area. The protection cover and protective fence
must be rigid enough to withstand the maximum possible
movement energy. EMERGENCY STOP switches must be easily
and quickly accessible. Prevent operation of the machine if this
protective equipment does not function correctly.

Mounting and connection
Flatness
If several linked clamping modules are mounted, make sure that
the flatness and height deviation of the locating surfaces from
clamping module to clamping module (based on a 100 mm gauge
for bore holes) is ≤ 0.02 mm. The gauge deviation may not exceed
± 0.015 mm.
Redundancy
Due to redundancy, the clamping pins with positioning accuracy in
one direction (SPB mini 20) should be used for clamping systems
that are more than 100 mm apart or that do not show a
positioning tolerance of ± 0.01 mm. For the clamping areas that
are not intended for alignment of the device or pallet, clamping
pins with centering clearance (SPC mini 20) can be used (also refer
to chapter "Clamping pins" (4.4, Page 24)).
Air bleeding for the piston chamber
When connecting the quick-change pallet systems, it is important
to note that it is only possible to completely bleed the air from the
piston chamber via the air connections during the locking 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, the relevant side of the piston must have a way of
being ventilated. This is done via the turbo connection itself.
Ventilation via turbo connection
Turbo connection
When using the turbo connection (if supply is connected), the
spring-actuated locking procedure is actively supported with air
pressure and in so doing strengthens the achievable pull down
force of the quick-change pallet system. One pressure pulse is
sufficient to increase the force. The pressure line can be decoupled
4.3

Assembly
20 05.00|1411420_NSE-HT mini 88-20, NSE-HT mini 88-20-V1 |en-US
afterwards without the pull down force being impaired. If the
turbo connection is not used, the relevant side of the piston must
be able to ventilate.
Connecting hose lines
If several quick-change pallet systems are activated via jointly
connected hose lines, feed lines with the following minimum
nominal widths for the hoses must be used.
Number of clamping modules
at least nominal hose width
1-4

When disconnecting hose lines, the relevant openings of the air
supply connections must be protected with seal plugs or cover
plates to prevent the ingress of dirt or coolant.
