4. SECTOR IRRIGATION
Sector irrigation enables the irrigation of different segments at different speeds (sectors from 1 to 8).
The number preceding the entry specifies the sector number. Number 1 is the first to be irrigated and, therefore, the most
distant sector from the irrigator.
The user menu should be employed to directly programme the sectors which will be used , as well as for setting possible
speed and length values. In this way, this data will be displayed at the beginning of every irrigation cycle, and could
then be adjusted at every single irrigation cycle for occasional variations.
When the device is switched on, the display shows the sectors which have been programmed in the menu. Press _m_ to
display the coiled meters; repeatedly press _m_ to scroll in sequence the length and speed of the various sectors. Any
data can be adjusted by pressing the central + and – keys.
We suggest to uncoil the tube or to programme the uncoiled meters before pressing _h_ .
The sectors are activated either by pressing _h_ or at the START phase, in relation to the length of uncoiled tube.
If the length of the uncoiled tube is greater than the sum of the lengths of the programmed sectors, then the last sector
will automatically be extended.
If the uncoiled tube is shorter than the sum of the lengths of the programmed sectors, then the sectors will be activated
starting from sector number 1 along the whole length of the uncoiled tube. Any sectors exceeding the length of the tube
will not be considered.
Afterwards it will be possible to modify the data regarding the length and speed of the various active sectors. It will not
be possible to directly modify the total meters of the uncoiled tube, which will be recalculated as the sum of the meters of
the various active sectors.
When rewinding the tube, the meters are decreased from the total length and also from the current sector, starting from
sector 1. When the meters belonging to a sector are completed, the speed of the following sector is automatically
regulated and so forth.
At the Rewinding End sensor’s signal, the final pause will be accomplished and the cycle will be completed.
Once the rewinding phase is concluded, if the tube has been extended, the irrigation will continue at the same speed of
the last sector until the Rewinding End sensor’s signal.
In case of deactivation, at the following outset it will be possible to resume the previous cycle. This may be avoided by
performing a RESET.
At every new cycle, the display will show the sector configuration and the pauses
which have been previously set on
the menu at START mode.
In this way ,the occasional modifications made by the operator and any possible automatic adjustment due to the
established irrigation time limit will be omitted.
