2 Function
2.1 Fascia Panel
The fascia is opened and closed by activating a touchpad sensor on the front.
The fascia panel drive is provided by a 24VDC motor and its power is applied
equally to either side via a number of gears. The complete fresh/condensed
water container assembly is transported to the front to simplify ease of
access to these parts.
Note:
The DC motor operates with only 12 volts in order to reduce the speed and
power of the fascia section movement.
Fascia panel movement begins after the sensor is activated. The fascia
mechanism includes a metal bracket which is moved forward or back. This
metal bracket activates a microswitch which indicates the end stop area.
When the microswitch is activated (end stop area), the fascia moves at a
slower speed. In the area where the microswitch is open, the fascia panel
moves at full speed. After a power failure or if the fascia is opened or closed
manually, the direction of movement attempted by the motor may be
incorrect. The mechanical block causes the motor (M19) current to rise. This
is detected by the electronic, which then acts to reverse the polarity of the
motor and the fascia moves in the correct direction.
At the end of a transport path, the microswitch is closed, the fascia panel
movement is at low speed and the end stop is reached. The mechanical
block causes the motor (M19) current to rise. The fascia panel transport
stops.
If the fascia panel is blocked when it is not at its end stop (microswitch open),
it automatically moves in the other direction. If a current rise at the motor
(M19) is detected when the microswitch is open, the polarity of the motor is
reversed and the fascia moves in the opposite direction. Information that the
fascia cannot be closed is shown in the display. If a blockage occurs in the
end stop area (microswitch closed), the polarity of the motor is not reversed.
The fascia stops and does not move any further. As the power transfer of the
motor is very low, it cannot cause injury.
