7.2 Safety switches
Care should be taken when driving the patient chair from one position to
another. Obstructions in the patient chair’s line of movement activate safety
switches that stop the motorised movements. The safety switches and their
functions are described below.
1. Backrest
An obstruction between the backrest and the floor when driving down the
chair and/or the backrest stops downwards chair and backrest
movements. Remove the obstruction to resume normal operation.
2. Chair bottom and lift adapter
An obstruction between the chair and the floor stops downwards chair
and backrest movements. Remove the obstruction to resume normal
operation.
3. Legrest
The position of the legrest is identified as ‘locked’ or ‘unlocked’ (= hangs
freely). Based on this information, the chair can be driven lower when it
is locked.
4. Bowl
The bowl is above the patient chair and stops upward chair movements.
Move the bowl into home position to resume normal operation.
5. Cuspidor door
The patient chair up/down movement is inhibited when the cuspidor door
is open. Also, the operation of instruments is inhibited. Close the door to
resume normal operation.
7.3 Stopping chair movements quickly
The chair movements can be stopped quickly by:
•
touching the chair buttons on the control panel,
• kicking safety switch number 2 on the chair bottom,
• pushing the foot control pedal or the centre knob in any direction, or by
• pressing the handle of the foot control.
