4.2 Brief description
A description of their function enables better understanding
of what telescopic pillars CPMA and CPMB and their individ-
ual parts do.
Functional principles
The functional principle of the telescopic pillars CPMA and
CPMB is based on a pushing force for the movement of cen-
tric and eccentric loads. The telescopic pillars CPMA and
CPMB have an integrated control unit and power supply
which is used as an individual lifting pillar.
A DC motor drives a lead screw via a bevel gear. A spindle
nut, which is attached to the push tube, moves up and down
on the lead screw. The telescopic tubes extend and retract
depending on the direction of the motor. The built-in brake
decelerates the movement or holds the position at a
standstill.
The telescopic pillars CPMA and CPMB for 100–240 V AC
are equipped with AC mains connection, and the mains volt-
age is internally transformed to 24 V DC. The telescopic pil-
lars CPMA and CPMB for 24 V DC are equipped with DC
connection and the voltage is internally transferred to the
control unit.
Control unit
The DC motor is driven via an integrated control unit. The
control unit controls the running direction of the telescopic
pillar and is equipped with an encoder for position detection.
During the acceleration or deceleration phase, the telescopic
pillars CPMA and CPMB use a soft start and soft stop func-
tion, which allows smooth running without jerking motion.
This function is automatically activated when buttons on the
operating device are pressed or released, or when the end
position is reached.
End position
The stroke is limited by the integrated control unit. If the tele-
scopic pillars CPMA and CPMB move beyond the end posi-
tion (in the case of a malfunction), after 3 mm a mechanical
block stops the movement. The control unit interrupts the
movement and the CPMA and CPMB can no longer be
moved in the blocking direction.
Outer tube base plate (a1)
The outer tube base plate has four connection nuts (b1) for
the fastening screws M6. Its purpose is to fasten the pillar to
one side of the application. The outer tube base plate must
be attached permanently with fastening screws M6 to a at
metal surface in the application, which has to support the
areas of force distribution (c1, c2, c3).
Outer tube (a2)
The outer tube is the tube with larger outside dimensions.
The outer tube can be located in upper or lower position of
telescopic pillars CPMA and CPMB.
Outer tube rim cover (a3)
The purpose of the rim cover for the outer and inner tube is
to protect the tubes’ guiding system from dust and to pre-
vent the ingress of foreign matter according to IP20. It must
not be removed under any circumstances.
Inner tube (a5)
The inner tube is the tube with smaller outside dimensions.
The inner tube can be located in upper or lower position of
telescopic pillars CPMA and CPMB.
Inner tube base plate (a7)
The inner tube base plate has four connection nuts (b1) for
the fastening screws M6. Its purpose is to fasten the pillar to
the other side of the application. The inner tube base plate
must be attached permanently with fastening screws M6 to
a at metal surface in the application, which has to support
the areas of force distribution (c1, c2, c3).
4.3 Special features
Guide tube unit (a2, a4)
The guide tube unit is made up of the outer tube (a2) and the
inner tube (a4), and its purpose is to carry centric and ec-
centric loads.
Drive unit
The permanent magnet motor is a 24 V DC motor and drives
the lead screw via the bevel gear. The speed of the move-
ment depends on the load and the direction of the move-
ment. The motor location can be selected on the inner tube
base plate or the outer tube base plate.

CPMA and CPMB
Bevel gear
The bevel gear drives the lead screw. It is driven via the per-
manent magnet motor.
Thermo-switch
The thermo-switch in the control unit controls thermal and
electrical overload and switches o the permanent magnet
motor in an emergency. The pillar cannot be operated again
until the drive temperature has fallen below the switching
threshold.
Switching o in the event of overcurrent
The control unit has an integrated switch-o facility in the
event of overcurrent, which protects the pillar from overload.
Brake
The brake is attached to the lead screw, and its purpose is
to decelerate the lead screw and hold the position.
4.4 Requirements for
third party power supply
(mandatory for telescopic
pillars CPMA and CPMB
24 V DC in medical
applications)
The operating voltage of telescopic pillars CPMA2 and
CPMB2 is 24 V DC. The no-load voltage of 32 V DC must not
be exceeded.
• After the system has been installed, ensure EMC compli-
ance.
• The third party power supply must have an isolation be-
tween the primary and secondary circuits according to
2 MOPP and provide a non-grounded secondary circuit.
• The third party power supply must be able to draw cur-
rents up to 20 A for 200 ms after switching on (start-up
current). For starting movement of the telescopic pillars
CPMA or CPMB, it must be able to draw currents up to
6,5 A for 1,6 s for nominal load pushing. During movement
according to the duty cycle of 1 minute ON and 9 minutes
OFF, it must be able to draw current up to 5 A.
4.5 Connections
Connection nut (b1)
The lower base plate and upper base plate are equipped
with connection nuts in each corner. The purpose of the
base plates is to attach the pillar to the at metal surface in
the application with fastening screws. The connection nuts
must not be removed under any circumstances.
Thread in connection nut (b2)
The purpose of the M6 thread in the connection nut is to fas-
ten the pillar to the application with fastening screws. The
fastening screws must have a screw-in depth of between
6 mm (min) and 11 mm (max) in addition to the interface
width of the application.
Terminal for operating device (b3)
The terminal for the operating device provides connection
for the operating device plug. Standard conguration is with
the operating device socket on the side of the motor. If the
optional conguration of an operating device on both sides
is selected, then the terminal on the opposite base plate
provides a connection for the second operating device.
Terminal for LAN cable through (b4)
The terminal for LAN cable through supplies connections on
both base plates for the LAN plug. It is necessary to use a
LAN cable with shielded plugs and for it to be shorter than
2 m on the bottom of the pillar to provide connection to the
network. This optional LAN cable through can only be
selected if the operating device through is not selected.
LAN and operating device cable channel (b5)
The cable channel provides space to place the cable for op-
erating device or LAN cable (CPMA only).
Mains cable channel (b6)
The cable channel provides space to place the mains cable.
The mains cable must be equipped with an outside diameter
of 8,2 mm ±0,5 mm.
Terminal for mains feed through (b7)
The terminal for the mains cable supplies external devices
with power via the mains cable feed through.
Areas for force distribution (c1, c2, c3)
The outer tube base plate and the inner tube base plate
must be attached to a at metal surface in the application.
The areas for force distribution have to be supported in the
application, and this support must not be removed under
any circumstances. The at metal surfaces must be at-
tached for force reasons and for EMC compliance according
to IEC/EN 60601-1-2.
