Master Channel :
Connecting valves :
The GARDENA extension modules
Art. 1277
with 2 channels are
available as an optional extra. Up to 4 expansion modules can be
connected and in this way 12 channels can be controlled via the
base unit.
1. Break off bar
4
from the watering controller (or already con-
nected expansion module).
2. Insert connection links
8
into the watering controller (or an
expansion module already connected) and push the expansion
module on.
3. Secure expansion module via the clamps
9
.
4. Connect the expansion module cable
5
using the connector
6
(if connecting another expansion module, connect the expan-
sion modules using the expansion module connector
7
).
The expansion modules are detected immediately by the
watering controller when connected.
5. Push on cover of watering controller and the expansion module.
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 master channel closes 20 seconds before the end
of the program so that the system is not under pressure.
The pump can be operated, for example, using the
GARDENA
Pump Control Art. 1273
that is connected to the master channel.
Labelling the valves :
1
Label the valves (
1 - 6
), so that the channels (
1 - 4
) of the
Watering Controller and the channels (
5
and
6
) of the
expansion module can be clearly assigned to the valves.
Connecting the valves to the Valve Box :
2
Connect one cable of the valve
V1
to the cable terminal
1
of
the valve box.
3
Connect the other cable of the valve
V1
to a cable terminal
C
of the valve box (All 4 cable terminals
C
are interconnected
and equivalent to one another).
4
Connect one cable of the valve
V2
to the cable terminal
2
of
the valve box.
5
Connect 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 :
6
Connect a cable terminal
C
of the Watering Controller to a
cable terminal
C
of the valve box. Both cable clips
C
are
connected to each other and equivalent.
7
Connect the cable terminal of channel
1
to the cable terminal
1
of the valve box.
8
Connect the cable terminal of channel
2
to the cable terminal
2
of the valve box.
Other channels can be connected similarly to the channels
1
and
2
.
