CAMT 20
WARNING
Injury due to cracks and related openings in the housing of
the actuator and/or its accessories.
If the housing is damaged due to stock, beakage or heavy wear,
cease using the device and follow the dismantling instructions.
WARNING
Any side-acting forces can destroy the actuator and pose a risk
of serious injury. During the stroke, do not manipulate any of the
elements connected to the actuator.
WARNING
Danger of injury caused by moving components
Rotating and/or linearly moving components can cause serious
injuries.
Therefore:
• Do not work on, or place, hand, 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 application or
system. It does not have its own operating control elements,
and does not have an independent emergency-stop function.
Therefore, the device must be installed so that it is part of an
emergency shutoff system and can be stopped if necessary.
The emergency shut-off 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-off system must always be freely
accessible.
NOTE
The processor decides which applications require installation of
an emergency shut-off 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 elements
and does not have a safety mechanism against unintended
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 an safety mechnism to prevent unintended
triggering of the operating device.
The following safety mechanisms have been
installed:
• Backup nuts are fitted on the leadscrew to prevent the lin-
ear actuator From collapsing if there is a gear nut failure.
• End limit switches are installed to provide a safe current
cut-off 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
supplycould be turned on without prior authorization. This
presents a potentially life-threatening situation for people in the
hazard zone.
Therefore:
• 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.
Protect CAMT against an unauthorized restart
Disconnect the power line plug out of the control unit and /
or the linear actuator.
