Detection
switch
(1) Normal operation
1UP/ DOWN
Air intake grille is raised/ lowered by
instructions of “UP”and “DOWN”.
Air intake grille does not move under the
state of no-load detection or obstacle detection.
Air intake grille stops automatically at the set lowering
distance from the ceiling level.
2STOP
It stops in the cases below :
•When it reaches at the set lowering distance from
the ceiling level.
It automatically stops based on the calculation at
distance from the time taken to lower.
•When it is stored in the panel.
Air intake grille is judged to be stored in the panel
when storage detection switch is pressed for 3 seconds continuously.
•When receiving instructions of “STOP”, “DOWN”while moving up and “UP”while moving down.
“STOP”button is only for the remote controller for Automatic Filter Elevation Panel.
As for wired remote controller, it takes several seconds to stop due to transmission speed.
•When both wire 1b and wire 2b are no-loaded.
Only the wire b in each UP/DOWN Machine has tension detection switch.
(2) Special operation
1 Re-storing operation
Case : Catch of grille or malfunction of storage detection switch
Re-storing operation will be done when storage detection switch is not pressed with air intake grille raised
by the set distance. And operation below will be repeated up to 4 times.
10cm down 30cm up ···· 10cm down 30cm up
2No-load detection
Case : “UP/DOWN”instruction without grille.
When both wire 1b and wire 2b are no-loaded, grille does not move.
3Obstacle detection
Case : Making contact with something while lowering.
When both wire 1b and wire 2b is no-loaded by making contact with something while lowering, it stops and
is raised by 10cm and stops again.
[Emergency operation]
•When the wireless remote controller cannot be used (in the case of battery discharge, misplacing of the wireless
remote controller, malfunctioning and so on), the emergency switch on the sensor can be used as an alternative.
* When doing this, particular caution must be taken not to fall.
To lower the air intake grille : Press the button once.
(For emergency heating operation, press this button.)
To raise the air intake grille : Press the button once.
(For emergency cooling operation, press this button.)
•To stop the air intake grille from moving, use the opposite buttons to those used to initiate movement.
(To stop it from lowering, press the “UP”button; To stop it from rising, press the “Down”button.)
•When up/down machine is out of order, fix air intake grille temporarily and indoor can be operated.
wFor details, refer to installation manual for grille.
