Operation Description
The displayed information are:
the operating mode
the internal dust filter pressure
active outputs and the time necessary to
activate the next output.
Manual Operating Mode
When manual operating mode is set, the economizer works as a programmable
cycle sequencer. The connected outputs will be activated at programmed time
intervals. Manual operating mode can be selected in the Main Set Up menu under
the first menu item.
Intervals are programmed in the same menu where activation time, pause time
and the number of solenoid valves connected to the device are set.
Automatic Operating Mode
When Automatic mode is selected from the basic set up menu, first menu item,
the economizer will work autonomously running pneumatic cleaning only when
necessary. If the device detects clogging over the dP Start Cleaning threshold,
cleaning is started.
If clogging drops under the dP Stop Cleaning threshold, cleaning is suspended
and turns off, until the pressure rises to a value over dP Start Cleaning.
When cleaning, the time in which the economizer cleans can be set in the basic
set up menu.
Proportional Operating Mode
By selecting the Proportional mode in the basic set up menu, the economizer
works autonomously initially setting the Start Cleaning threshold, pulse time and
pause time.
Automatically, when the Start Cleaning threshold is exceeded, the solenoid valves
are activated in sequence. If the dP threshold lowers 15% at the end of an entire
pulse cycle for the connected solenoid valves, cleaning is suspended until the
pressure rises over the dP Start Cleaning threshold.
If the dP value does not drop 15% under the Start Cleaning threshold, the pause
time frequency is automatically reduced proportionately at each complete cycle
of connected solenoid valve pulses, until a pause time between solenoid valves is
minimum 10 seconds. The minimum 10 second threshold was chosen to not
stress air distribution by the compressor connected to the filter.

Special Manual Operating Mode
In the basic set up men, first menu item, select Special mode, enter the pulse
time and pause time. Open the advanced set up menu, second menu item, enter
the number of complete cycles and pause time between these cycles for the
connected solenoid valves.
With this mode, unlike manual mode, the device only runs the solenoid valves for
the set number of cycles and will remain in stand-by until an operator presses S
(start / stop) in the main menu to repeat the cycles. This mode is especially
suited for small filters or filters where the dP has low values or the inverter
keeps pressure constant and it is hard to work with automatic and proportional
modes.
Other Function Descriptions
Alarms
This function allows an alarm device to be connected. The alarm device can be
connected to two alarm relays (see wiring diagram) which are opened when the
threshold set in the ALARMS menu is exceeded. For details, see the third menu
item and the description in the Accessing the Alarm menu section.
When an alarm is triggered, it is signaled on the display by a blinking row that is
normally occupied by the operating mode. The menu key is used for Reset and
keys can be used to scroll any alarm items that may have triggered for
relay no. 1: dP minimum ( if enabled in the menu ), dP Dirty Filter, Replace Filters
(if enabled in the menu) while failed valve activation is signaled with relay no. 2.

leaning Function With Fan Off Post- leaning
This function allows a cleaning cycle to be run with the fan off.
Post-cleaning is automatically activated in Automatic and Proportional operating
modes and when differential pressure drops under a threshold that can be set in
the advanced set up menu, second menu item.
While in Manual and Special Manual modes, it occurs through a contact
connecting the fan to terminals 12_1 on connector P9, see wiring diagram.
In the advanced set up menu, the following post-cleaning settings can be set:
Start cleaning with fan off (Enable/Disable)
Activation pressure (dP fan ON/OFF threshold)
Number of cycles (cycles completed)
Pause time (pause duration between one solenoid valve start and the
next during post-cleaning).
Pulse time (cleaning pulse duration regardless of the fan on operating
time).
Selecting The Number Of Outputs
The number of outputs, solenoid valves on which the economizer runs the
cleaning cycle can be selected. Cleaning is run in order from the first solenoid
valve to the last. Valve regulation is possible in the basic set up menu.
Pre- oating Function
This function lets you run pre-coating. Pre-coating is a filter element treatment
run with a powder called pre-coating powder. During the pre-coating phase,
cleaning is suspended until the dP pre-coating threshold is reached.
In the advanced set up menu, the following pre-coating settings can be set:
Pre-coating start: Enable on / Disable off.
Disable pressure dP Pre-Coating.
leaning Function From Remote ontrol
This function lets you pneumatically clean only after an external consent is
received. The external consent can be connected to prevent cleaning without
pressure in the high pressure circuit or in the compressed air tank.
The external contact must be voltage free, normally open and connected to
terminals 14_15 connector P9.
