Description Of Operation
The installed SW version and the s mbol ---, meaning that coherence between
settings stored in E2Prom and the set jumpers is being checked, will appear on
the displa when the economizer is powered up. A corresponding error code will
appear in case of discrepancies between settings (see Alarms Table). Onl editing
functions will be allowed on the unit. The operator ma switch off the unit and
configure the jumpers correctl .
S mbol 0_0 will appear on the displa if the test is entirel successful. The
following pages will then appear:
In automatic mode (F01=1):
dP value alternating with OFF if the enabling contact (14-15) is open
dP value alternating with -0- if the enabling contact (14-15) is closed and the fan
is off.
dP value onl if the fan is enabled and active.
In manual mode (F01=0):
OFF if the enabling contact is open (14-15)
-0- if the enabling contact (14-15) is closed and the fan is off
Manual Operating Mo e F01=0
The economizer will work as a programmable c cle sequencer in manual mode.
The connected outputs will be activated at the programmable frequencies. Manual
mode can be activated b accessing the configuration menu and setting F01 to 0.
F02 and F03 will set the activation time and the pause time, respectivel .
Automatic Operating Mo e F01=1
B selecting automatic mode (F01=1), the economizer will work autonomousl
can carr out the pneumatic washing c cle onl when needed. The device will
start the washing c cle if the obstruction is higher than Threshold_dP_Start
(F08). Washing is suspended when obstruction drops under Threshold_dP_Stop
(F09) level until it reaches a value higher than the Threshold_dP_Start threshold
once again. When washing is active, the economizer respects the times set in F02
(operating time) and F03 (pause time).
Automatic Mo e With Force Cycle F01 = 2
Identical to the automatic mode, except for the fact that it is possible to obtain a
cleaning c cle with the activation of the solenoid valves connected without
reaching the Threshold_dP_Start (F08). The forced cleaning interval ma range
from 1 to 999 h and can be selected through function F22 and F23.

10
Proportional Mo e F01 = 3
With the proportional mode, the economizer will work in full autonom , initiall
setting the dP_Start threshold (F08), activation time (F02) and pause time (F03).
When the Start Cleaning threshold is exceeded, the solenoid valves are
automaticall activated in sequence. If the dP threshold drops below 15% at the
end of an entire c cle of pulses of the connected solenoid valves, the washing is
suspended until pressure returns to a value above the Start Cleaning dP value. If
the dP value does not drop below 15% of the Start Cleaning threshold, the
frequenc of the c cle time is automaticall reduced in proportion with each
entire c cle of pulses of the connected solenoid valves, until a minimum c cle
time between solenoid valves reaches 10 seconds. The minimum threshold of 10
seconds has been chosen so as not to hamper the dispensing of air b the
compressor connected to the filter.
Cleaning Function With Fan Off (PCC)
This function allows to carr out one or more cleaning c cles (the number of
c cles is defined b F13) when the fan is off. The on or off state of the fan ma
be determined b the state of the contacts 12-13 (contacts open = fan off) if
F11=0, or ma be determined automaticall (with F11=1) when the dP pressure
drops under the threshold defined in F12. The pulse time of the valves will alwa s
be that defined in F02, while the pause time in this case is defined in F14.
The displa alternatel shows the number of the valve activated and the word PCC.
Number Of Output Selection
The number of outputs (solenoid valves) on which the economizer will run the
cleaning c cle can be selected. Cleaning will be carried out in order from the first
to the last solenoid valve. The valves can be adjusted b the F04 function.
Precoating Function (F18=1)
This function is used to carr out precoating. Precoating is a filtering element
treatment carried out with precoating powder. Washing and manual output
activation is suspended during precoating until the precoating thresholds defined
in F19 is reached.
The dP value and the message PC (precoating) will appear alternativel on the
displa .
P Zero Calibration (F07)
This function is used to reset dP reading with the fan off.
Increase or decrease the value shown b pressing “+” and “-” as required. This
value will be subtracted from the value read b the dP sensor.
P Sensor Self-Calibration
This function allows to reset dP reading with the fan off automaticall .
Hold “SET” and “OK” pressed at the same time with the device off. The message
“CAL” will appear after the start-up test. Release the buttons. The unit will go
back to normal state after a few instants. Automatic calibration is complete.

11
Fuse
A fuse which can be reset in case of need is located near the power terminal
board. Use a dela ed fuse 5x20mm as shown in the table on next pages.
SD Memory Car
The Micro SD memor card slot is located on the bottom right of the control unit
under the pol carbonate lid.
The card is not supplied with the control unit. A card with a maximum of 32GB
can be used.
The card must be formatted FAT32, which is the format recognized b all devices
and operating s stems.
Before removing the memor card, press the OK button with the control unit on,
wait for the cd (card) indication and the alternating flashing of the horizontal
lines of the third figure ≡. The card can now be safel removed. The Micro SD
Card connector is push-pull.
Press upwards and extract the card to remove it.
