The emergency shut-off system has to be connected in such
a way that a disruption of the power supply or the reactiva-
tion of the power supply after a power disruption cannot
cause a hazardous situation for persons and objects.
The emergency shut-off systems must always be freely
accessible.
Integration of an emergency-stop system (for
certain applications)
The device is only intended for installation into an applica-
tion or system It does not have its own operating control ele-
ments and does not have an independent patient release
mechanism.
If required by the application, a seperate provision for pa-
tient release has to be installed to allow safe release of a pa-
tient in case of emergency or equipment failure.
To increase more safety, anti-pinching
protection can also be connected (optional).
NOTE
The processor decides which application require the installation of
the following safety systems:
• Emergency shut-off system
• Patient release system
• Anti-pinching protection
NOTE
The TXG telescopic pillar does not contain displaying operational
conditions. For end applications in medical field it is mandatory to
ensure displaying operational conditions.
The following safety features may have been
installed:
• The TXG telescopic pillar is fitted with a thermoswitch. The
thermoswitch integrated into the transformer switches the
actuator off if the temperature becomes excessive. For
TXG10 a thermal protection must be provided by the used
control unit.
• End limit switches are installed to provide a safe current
cut off when the end position of the device is reached. In
case of failure of the end limit switches, an additional limit
switch prevents the device from exceeding its intended
stroke.
2.6 Safeguard against
restart
DANGER
Life-threatening situation through unauthorized restart!
For work in hazard zones, there is a risk that the power supply is
turned on without prior authorization. This presents a lifethreatening
situation for people in the hazard zone.
Therefore:
• Follow the information concerning the safeguarding against
re-starting of the power supply in the chapters of this operating
manual.
• Always follow the process to safeguard against a restart as de-
scribed below.
Protect TXG (AC version) against a restart.
Pull the power line plug out of the power outlet.
Protect TXG1 (DC version) against a restart.
Pull the power line plug of the Ewellix control unit or a mas-
ter actuator out of the power outlet.
WARNING
To avoid hazardous situations and to ensure optimal performance,
do not make any changes or modifications to the device unless they
have been specifically authorized by Ewellix.
