Proportional Operating Mode
By selecting the PROPORT. 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.
Cleaning Function With Fan Off Post-Cleaning
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 36_37 on connector P13, 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.
