11.4.11 Reserves and number of devices that participate in pumping
The multipump system reads how many elements are connected in communication and calls
this number N. Then depending on the parameters NA and NC it decides how many and
which devices must work at a certain time. NA represents the number of devices that
participate in pumping. NC represents the maximum number of devices that can work at the
same time. If there are NA active devices in a chain and NC simultaneous devices with NC
smaller than NA, it means that at the most NC devices will start at the same time and that
these devices will exchange with NA elements. If a device is configured with reserve
preference, it will be the last in the starting order, so for example if I have 3 devices and one
of these is configured as reserve, the reserve will be the third element to start, whereas if I
set NA=2 the reserve will not start unless one of the two active ones develops a fault. See
also the explanation of the parameters: 9.6 - NA: Active devices; 9.6 NC: Simultaneous
devices; 9.6 IC: Configuration of the reserve. In the DAB catalogue there is a Kit for the
integrated creation of a booster set of 2 systems. The booster made with the DAB kit appears
as in Fig.20
11.4.12 Wireless Control
As described in par. 11.4.3, the device can be connected to other devices by means of the proprietary wireless channel. There is therefore the possibility
of controlling particular operations of the system through signals received in remote mode: for example, depending on a tank level supplied by a float it is
possible to order it to be filled; with the signal arriving from a timer it is possible to vary the setpoint from SP to P1 to supply irrigation;
These signals entering or leaving the system are managed by a control unit that can be bought separately from the DAB catalogue.
12. MAINTENANCE
Disconnect the power supply before starting any work on the system.
The system requires no routine maintenance operations.
However, below are the instructions for performing the special maintenance operations that may be necessary in particular cases (e.g. emptying
the system to put it away during a period of inactivity).
12.1 Accessory tool
With the product DAB supplies an accessory tool that is useful for carrying out the operations contemplated on the system during installation
and any special maintenance operations.
The tool is housed in the technical compartment. It is composed of 3 keys:
1. metal key with a hexagonal section (Fig.21 – 1);
2. flat plastic key (Fig.21 – 2);
3. cylindrical plastic key (Fig.21 – 3).
Key "1" is in turn inserted in the end "D" of key "3". At the first use you must separate the 2 plastic keys "2" and "3", which are supplied joined by
a bridge (Fig.21 – A):
break the bridge "A", taking care to remove the cutting residue from the 2 keys so as not to leave any sharp bits that could cause
injuries.
Once the 2 plastic keys have been separated they can be used by
inserting "2" in one of the holes "B" in key "3": whichever hole is most
convenient, depending on the operation. At this point you obtain a
multifunction cross key, with a use corresponding to each of the 4 ends.

To use the cross key you must put the unused key "1" away in a safe place so that it does not get lost, or else put it back in its seat
inside key "3" at the end of operations.

ENGLISH
Use the key "1" for the orientation of the interface panel as described
in par 4.2.2. If the key is lost or damaged, the operation can be done
using a standard 2mm allen wrench.
