14 Planmeca Chair User’s manual
7.7.2 Automatic operation
The chair incorporates a memory in which you can store
the chair positions that you want the chair to move to in
the automatic mode. There are four chair positions
available: the rinsing position (C) and three working
positions (A, B, D). The positions have been
preprogrammed at the factory, and can be changed by
the user. See section 8 "PROGRAMMING CHAIR
POSITIONS" on page 15.
It is possible to disable the automatic movement to the
preprogrammed positions by connecting a jumper to the
Power supply PCB. Contact your Planmeca dealer, if
needed.
Push the foot control briefly to the position (A, B, C, or D)
where the preprogrammed chair position is stored. The
chair will move automatically to the preprogrammed
position.
Position C is the rinsing position. Push the foot control
briefly to position C and the chair will move to the
preprogrammed rinsing position. The chair remembers its
previous working position; push the foot control again
briefly to position C to return back to this previous position.
To stop the chair from moving before it reaches the
preprogrammed position, push the foot control in any
direction or press the backrest, the stop plate, or the stop
bar, or, press the stop cover on the underside of the lifting
mechanism upwards.
If you stop the chair by lifting the backrest, the stop plate,
stop bar or stop cover before it reaches its
preprogrammed position, you will hear a signal tone. You
will also hear a signal tone every two seconds when the
stop switch is active. To operate the chair again, use the
foot control.
If you wish to adjust the position of the chair when it has
reached its preprogrammed position, simply use the foot
control in manual mode to drive the chair to the desired
position.
