6b Disabling the menu:
Menu disabled for
Preset 1
7b Set the minimum and maximum control
PRESSURE of the system.
This menu has two purposes:
- Setting the function range of the control valve
If you set pressure values, the control valve operates
ONLY in that pressure range. Below the minimum value
and above the maximum value it no longer regulates.
The corresponding symbols are displayed on the job
page (figure a page 54 ):
Minimum pressure not reached
Maximum pressure exceeded
This function can be activated even if the pressure
sensor is not set.
- Generating an alarm
Set the pressure limits for the selected nozzle and enable
the appropriate function of the
Alarms menu (ref. 3-4 Fig.
87 on page 39 ) if you want the system to generate an
alarm when the nozzle is outside the set limits.
6b Make the menu active for configuration:
Menu enabled for
Preset 1
7b
Indicate the number of customized ranges.
8b Set the FLOWRATE of the control valve function range for your system.
You must enter the flowrate value of the nozzle you are using ( par. 11.5 Home > data and settings >
implement settings > Nozzle data ).
In order to obtain a more reactive system, it is possible to enter a flowrate value slightly lower than the
nominal one of the nozzle.
Below the minimum flowrate entered, the system will not regulate.
9b Set the maximum FLOWRATE of the control valve function range for your system.
You must enter the sum of the minimum flowrate ( par. 11.5 Home > data and settings > implement settings
> Nozzle data ) and the flowrate of the selected nozzles ( Fig. 79 ) (ref. 3 Fig. 46 on page 24 .
Above the maximum flowrate the system does not regulate.
The reference value can be found in the ISO standard nozzle tables and is relative to a pressure of 3 bar.
10b Select the
Nozzle shifts
menu to program nozzle combinations.
Nozzle shifts
Optimizes nozzle automatic selection: it allows setting up one nozzle combination, using ONLY
SOME in relation to a flowrate range.
Each range has a specific nozzle combination and an exchange flowrate that, once exceeded, will
make the computer use the combination of the next range:
11b
Select the nozzles to be used among the suggested ones for each range: should you disable
one or more nozzles, select them using arrow keys (one at a time)
12b Program the flowrate limit of the corresponding range.
Set all ranges.
