The following section lists the residual risks that have been
determined by a risk assessment.
• Heed the safety instructions listed here, and the warnings
in sub-sequent chapters of this manual, to reduce health
hazards and to avoid dangerous situations.
WARNING
Danger of injury caused by moving components
Rotating and/or linearly moving components can cause serious
injury.
Therefore:
• Do not work on, or place, hands ,arms or any other parts of the
body, close to moving components.
2.5 Safety equipment
Integration of an emergency-stop system (for
certain applications)
The device is intended only for installation into an applica-
tion or system. It does not have its own operating control el-
ements, and does not have an independent emergency-stop
function. Therefore, the device must be installed so that it is
part of an emergency shut-o system and can be stopped if
necessary.
The emergency shut-o system must be connected in such
a way that any disruption of the power supply or reactivation
of the power supply after a power disruption, cannot cause a
hazardous situation for persons or objects.
The emergency shut-o system must always be freely ac-
cessible.
NOTE
The processor decides which applications require installation of
an emergency shut-o system.
Integration of a patient release system (for
certain applications)
The device is intended only for installation into an applica-
tion or system. It does not have its own operating control el-
ements, and does not have an independent patient release
mechanism. In the event of a malfunction, the device cannot
extend or retract.
If required by the application, a separate provision for pa-
tient release must be installed, to allow safe release of the
patient in case of emergency, or equipment failure.
NOTE
The processor decides whether the intended application requires
the installation of an emergency patient release system.
Integration of a safety mechanism to prevent
unintended triggering of the operating device
(for certain applications)
The device does not have its own operating control ele-
ments, and does not have a safety mechanism against unin-
tended triggering of the operating device.
If required by the application, a safety provision must be
provided to prevent unintended triggering of the operating
device.
NOTE
The processor decides whether the intended application requires
the installation of a safety mechanism to prevent unintended
triggering of the operating device.
The following safety mechanisms have been
installed:
• The telescopic pillar CPMT is tted with a thermoswitch in
the motor, which switches o the telescopic pillar if the
temperature reaches a certain threshold, in order to re-
duce the risk of re.
• Backup nuts are tted on the ballscrews to prevent the pil-
lar from collapsing if there is a ballscrew failure.
• End limit switches are installed to provide a safe current
cut-o when the end of stroke position of the device is
reached. In case of failure of the end limit switches, a me-
chanical safety end-stop prevents the device from exceed-
ing its intended stroke.
2.6 Safeguard against
restart
WARNING
Life-threatening situation through unauthorized restart
For work in hazard zones, there is a risk that the power supply
could be turned on without prior authorization. This presents
a potentially life-threatening situation for people in the hazard
zone.
• Read the information contained in this manual, concerning safe-
guarding against any unintentional restart of the power supply.
• Always follow the procedure as described below.

Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic propagation is aected by absorption and reection from structures, objects and people.
1) Field strengths from xed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio
broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to xed RF transmitters, an electromagnetic site survey
should be considered. If the measured eld strength in the location in which the telescopic pillar CPMT is used exceeds the applicable RF compliance level above, the Model 006
should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the telescopic pillar
CPMT.
2) Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF communications equipment and the

4.2 Brief description
The functional principle of the telescopic pillar CPMT is
based on a push or pull force for the movement of centric
and eccentric loads. The CPMT requires an external control-
ler for it to be operational.
A DC gear motor attached to the middle tube drives two
spindle nuts simultaneously via a spur gear. The rotation of
the nuts induces a linear motion of the two ballscrews in op-
posing directions. The ballscrews are attached to the base
plates and cause an extension or retraction of the telescopic
tubes depending on the direction of motion. A built-in brake
holds the position at a standstill or during power cut.

CPMT
Outer tube base plate (a1)
The outer tube base plate has four holes to access attach-
ment bores in the outer tube (b1) for the mounting screws.
This enables the pillar to be fastened to one side of the ap-
plication. The outer tube base plate must be attached per-
manently with fastenings screws M10 to a metal plate in the
application, which has to support the areas of force distribu-
tion (c1, c2).
Motor cable (a2)
The cable (a2) exits to one side at the outer tube base plate
(a1) and has to be connected to an external control unit via
the DIN-8 plug or the ying leads cable attached.
Outer tube (a3)
The outer tube is the tube with the largest outside dimen-
sions. The CPMT pillar can be mounted in any orientation to
place the outer tube (a3) at the top or bottom of the
application.
Middle tube (a4)
The middle tube is the tube between the outer and inner
tubes.
Inner tube (a5)
The inner tube is the tube with the smallest outside dimen-
sions. The CPMT pillar can be mounted in any orientation to
place the inner tube (a5) at the top or bottom of the
application.
Rim covers (a6)
The purpose of the rim covers for the outer and middle tube
is to protect the tube guiding system from dust and to pre-
vent the ingress of foreign matter. The rim covers must not
be removed under any circumstances.
Glide pads (a7)
The purpose of the glide pads (a7) is to provide a sti, virtu-
ally play-free guiding of the tube sets.
Inner tube base plate (a8)
The inner tube base plate has four holes to access attachment
bores in the inner tube (b1) for the mounting screws. Its pur-
pose is to fasten the pillar to one side of the application. The
inner tube base plate must be attached permanently with fas-
tenings screws M10 to a metal plate in the application, which
has to support the areas of force distribution (c1, c2).
Mechanical safety end-stops (a9)
The purpose of the mechanical safety end-stops (a9) is to
block the extension of the tubes in the event of failure of the
end limit switches. This is a safety mechanism only.
Areas of force distribution (c1, c2)
The outer and inner tube base plates must be attached to a
support plate in the application. The areas of force distribu-
tion have to be supported in the application by an ade-
quately dimensioned support plate covering these areas.
This support plate must not be removed under any
circumstances.
Guide tube unit
The guide tube unit is made up of the outer tube (a3), middle
tube (a4) and inner tube (a5), and its purpose is to carry cen-
tric and eccentric loads.
Drive unit
The permanent magnet motor is a 24–30 V DC gear motor
and drives the ballscrews via a spur gear. The speed of the
movement depends on the load and the direction of the
movement. The motor and spur gear are attached to the
middle tube (a4).
Spur gear
The spur gear drives the ballscrews. It is driven via the per-
manent magnet motor.
End positions
The stroke is limited by the integrated end limit switches that
cut the power to the DC gear motor. If the CPMT moves be-
yond the end limit switches (in the event of a malfunction), a
mechanical safety end stop (a9) halts the movement.
Thermo-switch
The thermo-switch in the motor, controls thermal and electri-
cal overload and switches o the permanent magnet motor if
it overheats. The pillar cannot be operated again until the
drive temperature has fallen below the switching threshold.
Brake
The brake is attached to the gear motor. Its purpose is to
block the movement of the pillar during standstill or if the
power supply to the motor is cut.
External control unit
The DC gear motor is fed via an external control unit through
the cable connection (a2). The control unit controls the run-
ning direction of the telescopic pillar. An integrated 2-hall
encoder on the motor can be accessed by the controller to
enable variable speed control or positioning.
NOTE
Additional variations between CPMT pillars are given in the
appendix.

4.0 Structure and function
4.3 Requirements for
third party control units
(mandatory in medical
applications)
Control units not approved by Ewellix for CPMT pillars, are
treated as third party control units.
NOTE
It is strongly recommended to use original Ewellix controls for
the operation of the CPMT pillar. If third party controls are used,
there must be good documented evidence that the requirements
listed below are complied with.
The secondary circuit of third party control units must be
designed as an overvoltage category 1 circuit. The third
party control unit must be tted with an overload safety cut-
o. The maximum power input to the device should be only
0.5 A above the nominal value. The maximum shut-o value
may be only 1 A above the nominal value. For example: The
maximum power consumption is 12 A. The recommended
shut-o value is 12,5 A, the maximum cut-o value is 13 A.
NOTE
The current cut-o has to be set dierently if the main load
direction is in pull mode. Consult the Technical Data or
datasheet in this manual, for maximum power consumption
values for each type.
The third party control must enable the drive to draw cur-
rents up to 25 A for 200 ms after switching on (start-up cur-
rent). The excess power shut-o feature can also be tempo-
rarily de-activated for this purpose.
The operating voltage of the CPMT pillar is 24-30 V DC. The
no-load voltage of 36 V DC must not be exceeded. After the
system has been installed, ensure electro-magnetic compati-
bility. The operating time and duty cycle of the CPMT pillar may
not be exceeded (⮑ “Technical data”, Appendix, page 31).
NOTE
The third party power supply must have an isolation between
the primary and secondary circuits according to 2 MOPP, and
provide a non-grounded secondary circuit.
Push-to-run operation (recommended): The pillar operates
as long as the switch is pressed. The device does not have
signals to indicate operation, and depending on the applica-
tion, it is recommended to have an operational signal in-
stalled in the third party control unit.
For the 2-Hall encoder impulse transmitter, the third party
control unit must fulll the following additional requirements:
• Feed the hall sensors with a current of 4,5–26,5 V DC and
a current limit of no more than 200 mA.
• Load the hall sensor outlets with a maximum of 20 mA.
• Connect the hall sensor outlets to the supply with pull-up
resistors so that the signal of the open collector outlets
can be analyzed.
4.4 Connections
Electrical connection
The telescopic pillar is connected to the control unit via the
DIN-8 plug or the ying leads cable.
Connected load is 24 V–30 V DC and up to 12 A according
to the technical data (⮑ Appendix, page 31).
Important: Ensure that cables cannot get pinched or dam-
aged. Check that the mains voltage corresponds to the
nominal values on the type plate.

tachment bores on the outer and inner tube, which are acces-
sible through the top and base plates (⮑ g. 1, page 12).
Screw 8 × M10
Screw-in depth 25 to 35 mm in the pillar
Strength class 10,9
Tightening torque 40 Nm
CAUTION
The outer and inner tube base plates are not designed to
support the rated load of the pillar without additional support
provided by mounting plates. If a custom mounting plate is used,
ensure that it is dimensioned to provide sucient support of the
base plates.
The telescopic pillar CPMT can be mounted with the outer tube
or the inner tube at the bottom. If the inner tube is xed and the
outer tube is able to move in the application, ensure that there
is no possibility of strain or pinching of the power cable.
Any subsequent fastening bores in the aluminium tubes may
be made only by Ewellix.
Care must be taken not to damage or scratch the sides of
the tubes, as this can damage the guiding system and lead
to product malfunctions.
6.3.2 Installation steps
1. Remove the transportation screws from the mounting
bores at the outer and inner tube base plates.
2. Fasten the mounting plates, or the attachment points in
the application, to the mounting bores at the outer and
inner tube base plates.
Important: Screw in to a minimum of 25 mm and torque the
screws with 40 Nm.
NOTE
Fastening screws are not supplied. The bore dimensions can be
found in ⮑Plans and diagrams, page 32.
3. Check that all screws are suciently secured against
self-loosening.
4. Check that all interfaces and connections have been
mounted and/or connected correctly.
5. Ensure that the motor cable cannot be crushed, jammed
or pulled during operation, due to tension or pressure.
6. You are now ready to connect and operate the telescopic
pillar using the corresponding control unit and operating
device.
Before connecting the telescopic pillar CPMT to a control
unit, ensure that:
• the telescopic pillar CPMT is attached to the metal plates
of the application on both sides
• all attachment points are securely screwed to the application
• the elements are fully aligned and seated at the top and
bottom
• the areas for force distribution are supported
• the acting force does not impact the guide tubes with inad-
missibly high values, as side-impacting forces that are too
high can destroy the telescopic pillar CPMT
• the telescopic pillar is not obstructed in any way in the en-
tire lifting area
• the cables are not pinched, or caught or subject to tension,
bending, or pull stress.
WARNING
Risk of injury and device damage due to insucient
