5.7 Operation of the self-cleaning system
Models 126MA, 126TA, 236TA, 350TA and 469TA have a self-cleaning system for the filter that can operate
at intervals programmable according to requirements, limiting maintenance to the replacement of the
collection bag.
A timer controls the frequency of daily cleaning of the filter.
The operation of the device originates from a compressor that feeds a 7-litre air receiver tank with a preset
pressure of up to 4-5 bar.
At the time set in the inverter (to change the time setting, see below), the system generates three high-
pressure airshcoks at two-minute intervals for a period of about six minutes. These airshocks clean the filter
by blowing off the dust, which adheres to the outer walls of the filter, so it can fall into the dust container.
During the self-cleaning cycle, the vacuum system signals an "Autoclean ON" warning. The turbine
continues to operate for the duration of the self-cleaning cycle to prevent dust from exiting the inlet ports
located near the vacuum system.
This action keeps the filter clean for longer, thus reducing maintenance by the operator and ensuring better
vacuum system performance.
The filter cleaning parameters pre-set by the manufacturer are as follows:

Self-cleaning cycle with active turbine
The filter self-cleaning can occur either with the turbine in operation or with the turbine in stand-by.
Furthermore, for specific applications, up to eight fully programmable self-cleaning cycles can be activated.
To change these configurations, contact our technical department.
To change the filter self-cleaning cycle start time, proceed as follows:
1.
Enter the parameters menu as described in section 5.4.
2.
Select the "FAVOURITES" parameter list
3.
Enter parameter 34.12 and change the start time using the arrow keys and press "save" (
4.
Return to the HOME screen using the "BACK/EXIT key." (
MANUAL OPERATION
Press the Manual Self-Cleaning key to carry out a manual self-cleaning cycle (see Fig. 3 on page 13).
Looking at the pressure gauge located on the compressor, check that the tank has completely discharged
the compressed air. Then refill the tank at a pressure of 4-5 bar using the compressor located at the back of
the vacuum system.
Important: Do not open the dust collection container during the self-cleaning cycle. Wait at
least one minute after the end of the cycle before opening it.
Perform the annual inspection of the filter to check its integrity and if it needs to be
washed (once washed, the filter must be dry before it is reassembled).
All vacuum systems will signal a warning to check the filter status.
