3 Electronic Control
3.1 Motor power regulation
1. Main plug connected:
- Motor shall be off.
2. First start (after main plug is connected):
- Motor power starts in Max power position (remote version).
3. Power setting is changed by regulation button:
- Motor power steps up or down.
4. Cleaner is turned off by On/Off switch:
- Motor turns off; last power setting is remembered by the microcontroller (remote version).
5. Cleaner is turned on by On/Off switch after being at point 4:
- Motor turns on, and starts at the last used power setting (remote version).
3.2 RF transmitter
Introduction
The RF transmitter is used as remote control for a vacuum cleaner powered by a 3V changeable
lithium cell. The transmitter uses the 2.4 GHz (carry over from Ceres/Castor).band for transmitting data
inside EU. With the transmitter it is possible to turn the appliance on and off, and regulate the motor power.
Estimated lifetime for the battery in normal use is approximately 8-12 months.
Learning
If the PCB has not saved transmitter address –New PCB from supplier
1. Plug in the cord to the main. The motor will fluctuate.
2. Push the buttons in the given combination at the same time (to do this you have 20s after connection
to main )
/ 1+3+4 /
3. If the teaching was successful the cleaner will turn on (1.5s) and after that turns off.
4. The cleaner is ready to use.

Reset
If the receiver has saved transmitter address –New transmitter / New bentend
1. Plug in the cord to the main. Do not turn on.
2. Send Reset signal - 1+4 button combination at the same time (to do this you have 20s after
connection to main ) ) If the cleaner received the right reset signal it will fluctuate.
3. Unplug the cord from the main.
4. Wait min 5sec.
5. Plug in the cord to the main again. The cleaner should fluctuate.
6. Send teaching signal - 1+3 button combination at the same time (to do this you have 20s after
connection to main )
7. If the teaching was successful the cleaner will turn on (1.5s) and after that turns off.
8. The cleaner is ready to use.

4 TROUBLE SHOOTING
Problem
Checks
Cleaner does
n’t start
Cleaner without remote:
-
Investigate if the plastic knob reaches the ON/OFF switch on the PCB.
-
Replace the control unit (display PCB)
Cleaner with radio remote:
-
Investigate if both ON/OFF (cleaner and remote) is not working.
If remote ON/OFF w
orking, but not cleaner ON/OFF:
-
Investigate if the plastic knob reaches the ON/OFF switch on the PCB.
-
Replace the control unit (display PCB).
If cleaner ON/OFF working, but not remote ON/OFF:
-
Investigate if the LED on the remote indicates transmission. If
not, change
battery and try again.
-If still no LED indication on remote, change remote control and reprogram
the cleaner according to above instruction.
-If LED indicates transmission, try replacing the remote according to above
instruction. If cleaner starts, replace the RF remote control.
-
If still no function, replace the control unit in the cleaner. Be aware of the
position of the radio antenna. If replacing the control unit this has to learn the
RF-remote address according to above description.
If no rea
ction on any ON/OFF buttons: replace the control unit (display PCB).
Cleaner doesn’t start
-
Check if the Power module PCB gets main voltage.
-
Check communication wire between Power module and control unit for
failure or bad connection.
-
Change the control unit.
-
Change the Power module.
Cleaner doesn’t start
-
Check motor voltage, if no voltage, check the electronics as below, else
check motor TCO and motor.
-
Check communication wire between Power module and control unit for
failure or bad connection.
-
Change the control unit.
-
Change the Power module.
Not pon
ssible to
change power level
Cleaner without remote:
Investigate if the plastic knob reaches the
potenciometer on the PCB.
-Reseting the main/power PCB
-Change power regulation wheel
-Replace the control unit (PCB).
Cleaner with radio remote:
-Investigate if the LED on the remote indicates transmission. If not, change
battery and try again.
-If still no LED indication on remote, change remote control and reprogram
the cleaner according to above instruction.
-If LED indicates transmission, try replacing the remote according to above
instruction. If cleaner starts, replace the RF remote control.
-
If still no function, replace the control unit in the cleaner. Be aware of the
position of the radio antenna. If repla
cing the control unit this has to learn the
RF-remote address according to above description.
No failure found
If no any
fault found after
investigate the
appliance, then use
following coding
Product: 901
-
Please use correct defect code to describe problem details, such as 53
(Customer misuse), 54 (Instructions missing or unclear), 55 (Not meeting
expectations), 57 (No fault found)
