cleaner is turned on, it will start in AUTO mode.
If turned off when running in AUTO mode, the power bar shall show “walking light”, and the “AUTO”
LED:s shall be turned on.
If turned off in manual mode, the last indicated power shall start to flash with 1Hz. The “AUTO”
LED:s shall always be turned off, both when running in manual mode or when in stand by for manual mode.

- Keep the ON/OFF button pressed until the AUTO LED:s start flashing, the cleaner is now in RF
learning mode. Release the ON/OFF button.
- On the remote control press the ON/OFF button.
- If the cleaner have received the new RF remote address the power bar will start flashing, indicating
that the learning process is finalized.

3.7 Auto function, pressure sensor PCB (position 014D)
Auto function is a function for automatically regulate the motor power depending on the air pressure.
To the control PCB a pressure switch/sensor PCB is connected. The control PCB senses that the auto board
is connected and activates the software for automatic power regulation.
The Auto PCB is connected to the Control unit PCB like below sketch:
If pressure PCB is not connected, this will be indicated on the display by flashing the AUTO LED:s
with 1 Hz.
3.7.1 Functional description
When the pressure is too high the pressure switch is activated, and the controller starts to d ecrease
the power. When the switch is inactivated, depending on to low pressure, the controller starts to increase the
motor power until the switch activates.
In normal auto mode this means that the motor power will oscillate around the pressure setting of the
pressure switch.

4 PCB Power Module (position 014A)
4.1 Introduction
Power module is intended as a module PCB for mainly vacuum cleaners from Electrolux Floor Care
& Small Appliances AB. The module is intended to consist of a Triac, triggering a motor, and a power supply
for additional connected electronic.
The component layout for the power module should look like below sketch:
1. Power Module PCB.
2. Connector main voltage
3. Alternative main power connector / main power out
4. Motor connector
5. Connector to control PCB
All different kinds of Power modules have the same configuration of connector configuration, simplifying
design, service and cross over.
4.2 Connection for control unit
To be able to control the power module a control unit is connected to the 5-pol connector, which also
power supplies the control unit with 5VDC.
The configuration for the connector is following:
1. Ground.
2. 5VDC, maximum current according to level of power module.
3. Zero cross signal, square wave that follows the main frequency (5V amplitude).
4. Reserved for TCO signal (temperature control signal). Not implemented on the PCB, only
reserved for the function.
5. Triac ignition signal from the control unit to the power module.

4.3 Low Current Power Module
The low current power module contains a capacitive power supply.

5 RF transmitter
5.1 Introduction
The RF transmitter is used as remote control for a vacuum cleaner powered by a 3V changeable
lithium cell. The transmitter uses the 433MHz 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.
5.2 Design
5.2.1 Mechanical design, PCB shape
SW1 – Auto function on/off
SW2 – Cleaner on/off
SW3 – Manual power step
5.3 LED indication
The assembled LED is intended to communicate the battery status to the user. When there is no
LED indication it is time for the user to change the battery. In normal condition (standby) the LED are
inactivated. If a button is pressed the LED activates for approximately 250 milliseconds.
5.4 Changing the battery
Change the battery when light indicator is not responding when pressing any button. Observe polarity of
battery.

6 Aeropro PCB 230V/110V motor
6.1 Introduction
Aeropro PCB 230V is a new PCB to support the drive of a 230VAC motor mounted in the Aeropro
nozzle. The motors continuously current consumption is maximum 1A. The PCB can also be used without
nozzle motor, and then only support a wired remote control between the cleaners bent end and the cleaners
control unit.
6.2 PCB variants
The 230V variant use single sided PCB. Low voltage variant (100V for USA, Japan) use double sided PCB
together with UL approved coating.

6.3.1 Functional description
The Aeropro PCB is supplied with main voltage, dimensioned to be used with both 230V and 100V
main power. A capacitive power supply is used to supply the electronics with 5VDC. The motor speed and
motor status in the nozzle are controlled by a triac. The triac are controlled by the cleaners control unit.
6.4 Description Remote control signal and handling
The remote control is connected to connector on the Aeropro PCB. The remote control uses a two
wire connection to the Aeropro PCB, and is connected as following:
- KEY +5V analog signal.
- M2 GND. Note: live voltage potential.
The controller on the Aeropro PCB reads the analog signal level, and converts the signal to a frequency
output signal, which is communicated to the Elara control PCB.
6.5 Motor output
The on/off of the motor nozzle is controlled by a Triac.
The motor is also connected as follows
- M1 motor phase
- M2 motor neutral (shared with the GND for the remote control)
Nozzle motor status is following:
Plug in: OFF
Switch cleaner on: OFF or last status.
Switch cleaner off: OFF
Auto on: No change
Auto off (manual): No change
Manual power toggle: No change
Nozzle on/off: If nozzle motor is off and cleaner motor running – turn it on
Nozzle on/off: If nozzle motor is on and cleaner motor running – turn it off
Cleaner motor is off: Always off.
7 INDICATION & DIAGNOSTICS
7.1 Filter and S-bag indicators
7.1.1 Activation
The indicators are operated by the controller. If the pressure switches activates, this is indicated by
the indicator LED:s.
After 2 seconds activation the corresponding LED will light up for 1 second, and after additional 57
seconds the corresponding LED will start to indicate continuously.
During this time delay the pressure switch must not be deactivated. If it is deactivated, there will be a
new 60 second delay when activated next time.
The LED:s will continue to indicate after the cleaner is turned off and in standby mode.
At first start, after the main plug is connected, the S-BAG and FILTER indicator will turn on for one
second,
indicating that the LED:s is working.

7.1.2 Deactivation
To deactivate the LED indicator after activation this can be made in three ways. First is to disconnect
and reconnect the main connector.
Also this can be made by turning off the cleaner, turn it on again and keep the on/off button pressed
for 5 seconds.
At last when turned on after being activated, and running without the actual pressure switch is
activated for 30 seconds.
7.2 Error handling
7.2.1 General startup error
If the micro controller doesn’t receive any signal, the triac triggering is turned off, and the power
LED:s start to flash with 1 Hz. No other functions are activated. To start the cleaner again, the main plug
must be disconnected and connected again.
7.2.2 Auto board error
On RF- and active versions, if the auto control PCB is missing, both bag and filter LED starts to flash
with 1 Hz. It will still be possible to run the cleaner in manual mode. If either the filter or the bag switch is
activated, this LED will light continually according to description in chapter “Filter and S-bag indicators”, while
the inactivated LED will continue to flash.
7.2.3 Aeropro PCB error handling
If the control unit receives an error signal from the Aeropro PCB, or no signal at all, the cleaner motor
stops and a signal sent to the Aeropro PCB to stop the nozzle motor. AUTO LED:s indicating failure by
flashing with 1 Hz if no signal is received. If error signal, this is indicated as a normal on/off –
“walking light”.
