3 Levels of Electronic Control 3.1 Display Layout for models without remote controlled HBTN: 3.1.1 Basic software functionality - ON/OFF switch Soft-start, function according to chapter “Softstart and motor power change”. Automatic 50/60Hz detection. When started, raise power to maximum power. ( + ) increase motor power, one press increase power with one step. After maximum power has been reached, the power stays in maximum power independent further activations of the “+” button.
3.2 Display Layout for models with RF controlled HBTN: 3.2.1 Basic software functionality - ON/OFF switch Soft-start Automatic 50/60Hz detection. When started from unplugged, cleaner starts in AUTO mode, otherwise in last used mode. Toggle between cleaning modes, 5 manual power steps. Power indication, “fading light”. 6 light intensity levels for LED:s when running in auto. In manual mode, one LED per power level. LED1 in power step 1, LED2 in power step 2.. AUTO lightened when function activated.
- Motor turns off; last power setting and mode is remembered by the microcontroller. - LED indication shows the last used power setting by flashing the corresponding LED with 1Hz, same function as for level 1. 7. Cleaner is turned on by one of the On/Off switches after being at point 6: - Motor turns on and run into manual mode, and starts at the last used power setting. - LED indication shows used power setting, with continuous light. 8.
3.3 Display Layout for models with Aeropro active system: 3.3.1 Basic Software functionality - ON/OFF switch Soft-start Automatic 50/60Hz detection When started from unplugged, cleaner starts in AUTO mode, otherwise in last used mode. Toggle between cleaning modes, 5 manual power steps. Power indication, “fading light”. 6 light intensity levels for LED:s when running in auto. In manual mode, one LED per power level. LED1 in power step 1, LED2 in power step 2.. AUTO lightened when function activated.

- 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. On the cleaner, press the ON/OFF button. The cleaner will now be in standby mode. Start the cleaner either with the remote control or on the cleaner. 3.6.
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.
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.
4.3 Low Current Power Module The low current power module contains a capacitive power supply. The low current power module can always be replaced by a high current power module, or International power module (see parts lists). 4.3.1 Power supply design low current power module The 5V power supply is of the type capacitive supply. Principal schematic: 4.3.2 Electrical specification Input voltage: Output voltage: Max output current: 230V / 50Hz. 5V 35mA@4,8V.
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.
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.
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.
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.
8 TROUBLE SHOOTING Problem Checks Cleaner without remote: - Investigate if the plastic knob reaches the ON/OFF switch on the PCB. - Replace the control unit (display PCB) Cleaner doesn’t start; if standby is indicated on display Cleaner with radio remote: - Investigate if both ON/OFF (cleaner and remote) is not working. If remote ON/OFF working, but not cleaner ON/OFF: - 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 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.
