Electrolux Oxy3etage, Manual

Characteristics of the circuit card

1. Soft start

The moment of start is delayed with a TRIAC relay, giving a delay 
of start-up current to the motor with about 1 second. The start-
up tension will in this way be much lower, which in turn means 
that the wear on fuses, circuits and motor will be lower.

2. Low tension LED Auto-polarity *2 

The green LED for the power cable, which is on the unit, will 
always shine when there is current

3. Counter for hours worked *3

Through the use of EEPROM technology (program memory), 
the card registers two types of timings that the user can easily 
control, using a simple LED indicator that is placed on the shield 
of the circuit board.

a

. Short time 

b

. Total time

4. Test of functions

After the power cable has been connected, the circuit board 
performs a test of functions.
If everything is OK, the LED will flash rapidly for a few seconds 
and then stop. Delay in shutdown. When turning off the vacuum 
cleaner, a 2 second delay will be added in order to ensure that 
the pipes and the hose are empty when the unit is turned off.

  how the pipe are laid out, and by noting where the suction is 
  still good, it should be possible to logically work out where the 

stoppage is located. 

5. Imagination? Many people, who just have had central vacuum 

cleaners installed, are making an error in determining the suc-
tion, because the sound effects are absent.
