In the picture to the
right you will see the
connection of the
temperature sensor
(red tabbed lead) into
the pin marked TEMP.
The Speed Sensor Coil
(Black tabbed lead) is
connected to the pin
marked SPEED. The blue
Data cable is connected
in to the ‘CNTL’ plug. All
of these leads need to be
fed through the rubber
grommet in the wall of the
control box.
The smaller inlaid picture below shows the JMP3 and JMP1 plug switches.
These, when set correctly, determine what fan size the PCB board will
operate.
Because there are three (3) different size fans that this one control box can
operate it is important to set the control box to the right sized fan. The plugs
location on each of the 3 sets of pins is critical in the fans correct operation.
It is important that the control box is UNPLUGGED from power when
you change the positions of these plugs!! If you change these plugs when
the control box has power flowing to it, will BLOW the safety fuse and the
control box will need to be returned to Cardiff Air.
As you can see in this
picture the factory settings will be / JMP1 has been set in position 2 / and JMP3
is in position 1. This tells us that the control box is setup to run the Cardiffair
900 unit.
• For a Cardiff Air 550
Unit JMP1 will need to be
changed to Position 1
• For a Cardiff Air 900
Unit JMP1 will need to be
changed to Position 2
• For a Cardiff Air 1070
Unit JMP1 will need to be
changed to Position 3
JMP3 REMAINS IN
POSTION NUMBER 1
(ONE) AT ALL TIMES.
The next step in the installation process is to connect the Louvre Actuator
Assembly motor to the PCB.
Feed the figure eight cable through the rubber grommet along with the speed
sensor pick up coil, temperature sensor and RJ45C data cable. The figure eight
cable is grey and grey with a black trace. Connect the grey lead to the positive
terminal marked on the PCB. Connect the grey with the ‘Black’ trace to the
negative terminal. Double check that all connections are secure and place the lid
back on the top of the control box.
Plugged in Louvre Actuator neg and pos shown.
Complete!
You have now successfully completed the installation for a Cardiffair Motor Unit.
