Installation, Operation and Maintenance Manual – FMA 3000
Ref: 3000/T/6/VH 27
12.2. – OPERATION
The programming unit controls automatic cleaning of one filter. Cleaning can be started in three
ways:
 Manual cleaning.
You must hold the manual cleaning button for 5 seconds.
 Differential pressure cleaning
Standard configuration: 0.3 bar.

Time cleaning.
Standard configuration: 12 hours.
In order for its use to be as reliable and simple as possible, the control panel has been equipped
with an electronic differential pressure sensor. An external differential pressure can be optionally
used (pressure switch).
The control unit is ready to activate 12 V two-wire latching solenoids.
As appropriate, the programming unit power can be 6 V DC or 12 V DC.
When the programming unit works by differential pressure, the system will continuously detect
cleaning problems if after 7 consecutive cycles, the differential pressure sensor requires a new
cycle (see list of audible warnings).
