Functional Description; Description Remote Control Signal And Handling; Motor Output - Electrolux EL4300 Service Manual

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 Power Module 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:
