Master Channel:
Connecting the valves:
The master channel is a channel that can be operated at the same
time as other channels. This is important, for example, if you want
to use a pump to supply your irrigation system with water and if
the pump should always be activated each time an irrigation valve
is activated.
The pump can be operated, for example, using the GARDENA
Pump Control Art. 1273 that is connected to the master channel.
The example shows the connection of 2 valves Art. 1278 in the
Valve Box Art. 1255 to the Watering Controller 4030 / 6030.
As the output of the Watering Controller is 24 V AC (alternating
current) for switching the valves, it is does not matter which of
the two cables of a valve is inserted into C.
Labelling the valves:
1Label the valves (1
-
6), so that the channels (CHANNELS 1,
CHANNELS 2, …) of the Watering Controller can be clearly
assigned to the valves.
Connecting the valves to the Valve Box:
2Connect one cable of the valve V1 to the cable terminal 1of
the valve box.
3Connect the other cable of the valve V1 to a cable terminal C
of the valve box (All 4 cable terminals Care interconnected
and equivalent to one another).
4Connect one cable of the valve V2 to the cable terminal 2of
the valve box.
5Connect the other cable of the valve V2 to a cable terminal C
of the valve box.
Other valves can be connected similarly to
V1
and
V2
.
Connecting the Watering Controller to the Valve Box:
6Connect a cable terminal Cof the Watering Controller to a
cable terminal Cof the valve box. Both cable clips Care
connected to each other and equivalent.
7Connect the cable terminal of channel 1 CHANNELS 1 to
the cable terminal 1of the valve box.
8Connect the cable terminal of channel 2 CHANNELS 2 to
the cable terminal 2of the valve box.
Other channels can be connected similarly to
CHANNELS 1
and
CHANNELS 2
.
Cable cross-section of the connection cable:
The maximum permissible distance between the Watering
Controller and the valve depends on the cross-section of the
connection cable. For a distance of 30 m, the cross section is
0.5 mm2and 0.75 mm2for a distance of 45 m. No more than
3 valves must be in operation at the same time.
The GARDENA connection cable Art. 1280 is 0.5 mm2in size
and is 15 m long. Up to 6 valves can be connected using this
cable. The connection cable can be connected so that it is
watertight using the cable clip Art. 1282.
