Field Setting; Field Setting Switches; Dip Switch Setting - Fujitsu AOU36RLAVM4 Installation Manual

6.6.2 External input terminal
Setting to low noise mode, cooling priority/heating priority selection, outdoor unit operation
peak control setting, emergency/batch stop and electricity meter pulse are possible from
the outside.

* If the outdoor unit is not installed in the wall, cover
the exposed part of cable with a 1 mm thick or more
tubing.
insulation
Wiring method and specifications
* A twisted pair cable (22 AWG (0.33 mm²)) should be used. Maximum length of cable is
492 ft (150 m).
* Use an external input and output cable with appropriate external dimension, depending
on the number of cables to be installed
* For each input, pin No. 1 is of positive polarity and pin No. 2 is of ground level.

The operations of each input terminal and the selection of function are set with the push
button on the PC board of outdoor unit. About the setting, please refer to "7.4. Push button
setting".
NOTE:
*1: The "external input priority mode" must be set by pressing push button on PC board
of outdoor unit. (Refer to "7. FIELD SETTING".)
*2: Batch stop or Emergency stop pattern can be selected by outdoor unit PC board
push button. (Refer to "7. FIELD SETTING".)
*3: The emergency stop function mounted in this product does not guarantee the regu-
lations of each country. For this reason, sufficient checking is necessary regarding
use.
Especially, since the fact that the equipment may not be emergency-stopped in the
case of breaking of the wiring to the external input terminals and communication
line, communication error due to noise, VRF external input circuit trouble, etc. must
be considered, the provision of double measures that add direct interruption of the
power supply by switch, etc. is recommended as a precaution.
*4: Pulse input to CN135 must be width 50 ms or more, and must be interval 50 ms or
more.

*5: Provide a DC 12 to 24 V power supply.
Select a power supply capacity with an ample surplus for the connected load.
*6: The allowable current is 30 mA or less.
Provide a load resistance such that the current becomes 30 mA or less.
*7: Polarity is [+] for pin 1 and [-] for pin 2. Connect correctly.
Do not impress a voltage exceeding 24 V across pins 1-2.
* A twisted pair cable (22 AWG (0.33 mm²)) should be used. Maximum length of cable is
492 ft (150 m).
* Use an external input and output cable with appropriate external dimension, depending
on the number of cables to be installed.

7. FIELD SETTING

Input5
Discharge the static electricity from your body before setting up the DIP switches.
CN135
Never touch the terminals or the patterns on the parts that are mounted on the PC
(Orange)
board.

7.1. Field setting switches

Remove the service panel of the outdoor unit and the cover of the electrical component
box to access the PC board of the outdoor unit.
PC board switches for various settings and LED displays are shown in the figure.
