Safety
Integration of a patient release system (for certain applications)
The device is intended only for installation into an application or sys-
tem. It does not have its own operating control elements, 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 patient
release must be installed, to allow safe release of the patient in case
of emergency, or equipment failure.
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.
The following safety mechanisms have been installed:
•
The telescopic pillar CPMT is fitted with a thermoswitch in the
motor, which switches off the telescopic pillar if the temperature
reaches a certain threshold, in order to reduce the risk of fire.
•
Backup nuts are fitted on the ballscrews to prevent the pillar from
collapsing if there is a ballscrew 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 mechanical safety end-stop
prevents the device from exceeding its intended stroke.
!
Note!
The processor decides whether the intended application
requires the installation of an emergency patient release
system.
