2.2 Other hazards
The manufacturer has constructively, and with protective
measures, minimized the eects of existing residual haz-
ards. Pay attention to the residual hazards and the potential
countermeasures given in the following chapters
Residual hazards to people, objects and
property
Pay attention to the following residual hazards and the pos-
sible countermeasures for dealing with them.
WARNING
Warning against hand injuries caused by trapping. Do not let any
object or person come into contact with the inner tube and/or the
final plate while the motor is running. Hold the TLC only by the
external tube
WARNING
Warning for risk of crushing and damage to the TLC caused by
static and dynamic overloading of the telescopic pillar. When
driving against fixed objects the impact of the force can cause
personal injury. Make sure that there are no persons or fixed
objects present in the danger zone during the strok
• Note the maximum permissible operating data in the Appendix
(⮑ Technical data, page 17)
• Note the type plate of the telescopic pillar
WARNING
Warning of side-acting forces. Excessive side-acting forces destroy
the pillar and pose a danger to persons. During the stroke, do not
manipulate any of the elements that are connected to the TLC.
• You can nd the maximum permissible values in the appendix
(⮑ Technical data, page 17)
CAUTION
Beware of electric shock due to a squashed cable. Ensure that
cables cannot get pinched or damaged. Check that the mains
voltage corresponds to the nominal value on the type plate. Ensure
that the strain relief clamp and cabling are correct
CAUTION
Beware of damage to the TLC caused by splashing or hose-
directed water. The telescopic pillar TLC is, in accordance with
IP30, not protected against splashing or hose-directed water.
Exposure of the TLC to splashing or hose directed water must be
prevented at all times
• If required, protect your telescopic pillar with appropriate protec-
tive measures.
CAUTION
Beware of personal injury caused by the application falling off. The
final plate, which is made of plastic, can break when under load. It
is prohibited to operate the telescopic pillar TLC without adequate
support for the fastening plate or without an adapter plate!
Reinforced adapter plates are available as accessories
(⮑ 4.1.2 Accessories, page 20).

3.0 Function
9
3.0 Function
3.1 General function
The TLC is an electrical linear actuator which uses virtually
play-free guide tubes. It has been designed for holding and
moving centric and eccentric loads.
An AC motor drives a threaded nut that is fastened in the ro-
tor shaft. This nut then runs up and down the torsionally rigid
threaded spindle, which thereby generate the feed motion.
The telescopic tubes are retracted and run out depending on
the direction of the motor.
The AC motor is operated as a capacitor motor on a sin-
gle-phase AC voltage network.
3.2 Correct use
The TLC has been designed specically for adjusting equip-
ment carriers, lifting tables, chairs and oce furniture which
comply with standards EN 60601-1, EN 60601-1-2 and UL
2601.
The TLC should only be subjected to compressive loads. It is
only suitable for indoor use and must not be subjected to the
elements.
For pull applications, specially equipped pull version actua-
tors are available.
Specify the direction of load when ordering. The unit must
not be converted or modied.
CAUTION
Where eccentric loads are involved, the permissible maximum
load decreases. Please observe the permissible load on the load
diagram contained in the datasheet. If an eccentric overload occurs,
the actuator can be damaged. The load can tip sideways.
3.3 Ambient conditions
3.3.1 Operation
• Temperature 10 °C to 40 °C
• Humidity max. 85%
3.3.2 Storage / transport
• Temperature -20 °C to 40 °C
• Humidity max. 95%
WARNING
The TLC telescopic actuator must not be operated in an explosive
atmosphere.
NOTE
For transport purposes, the TLC defined for push load can be
loaded with a pull force of up to 50 kg for a short period.
CAUTION
The maximum centric load specified on the data label and the
permissible eccentric load specified in the transverse load diagram
must not be exceeded. A push actuator must never be used to
pull. The actuator may be destroyed if these instructions are not
observed.
3.3.3 Operating mode
See Technical Datasheet.
The actuator has been designed for intermittent operation. If
a higher duty cycle is required, contact Ewellix
CAUTION
If the duty cycle is too long, a temporary malfunction may occur.

3.4 Construction
The TLC is tted with a thermal fuse. The thermoswitch inte-
grated into the motor winding switches the actuator o if the
temperature becomes excessive. After cooling down, the
thermoswitch is reactivated automatically
CAUTION
The first failure safety of the overall system must be checked in the
end product in order to rule out risks to life/limb and property.
3.4.1 Control unit
The TLC telescopic actuator is controlled by external pneu-
matic control devices, an electrical cable via which the mo-
tor's direction of rotation is controlled externally, or via a
low-voltage interface using an electrical handswitch or
footswitch.
Feeding and control of the actuator is possible at either the
top or the bottom as standard. This cable feedthrough is
permitted for 230 V, 6 A.
The TLC has extensive protection against faults. First failure
safety cannot be ensured, however, since unpredictable
faults - e.g. to a control device - can result in slow, uncon-
trolled movements.
3.4.2 Terminal-position shutdown
The stroke of the TLC is limited by the integrated limit
switches. These switch o the actuator.
