Safety stop
The treatment center is equipped with various safety stops to prevent
crushing and damages. The cutoff trigger points are shown in the
following illustration:
Display of triggered safety switches (all shown on one illustration)
The following occurs when one or more safety switches is triggered:
● all safety switches cause an acoustic signal to be played twice each
time a movement stops or starts. Exception for cuspidor: here only
when movement starts
● All chair movements stop immediately
● The triggered safety switches are displayed on the touchscreen.
● when the patient chair moves (this does not apply to the assistant
element or swiveling cuspidor), a corrective movement is carried out
in the opposite direction for approx. 2 seconds. Exception for lift
frame: here the corrective movement is always upward
As long as a safety switch is activated, the operation of the treatment
center is restricted.
If a safety switch is permanently blocked, please contact your service
engineer.
