CONNECTING VALVE WIRES
Connecting Station Valve Wires
Each
station
module
that
has
been inserted
has
a
grouping
of
six station
screw terminals corresponding
to
that
particular expansion slot. Once a
station
module
is
inst
al
led
in
a
module
slot, the station screw terminals
assigned
to
that
module, which are located directly
below
the
station
module, become active.
Each
station
output
is rated for 0.56A max,
or
enough
to
operate
two
Hunter AC solenoids simultaneously.
1.
Route valve wires between control valve location and
the
controller.
2.
At
the valves, attach a common wire
to
either solenoid wire
of
all the
valves.
Th
is is
most commonly a white colored wire. Attach a separate
control wire
to
the
remaining wire
of
each valve. All valve wire splice
connections should
be
done
using
waterproof
connectors.
3.
Open
the faceplate
at
the
controller
to
expose
the
numbered station
terminals.
4.
Route valve wires through
the
conduit and attach the
conduit
to
the
controller
at
the 1 W'
(37
.5 mm) opening at the
bottom
of
the
cabinet.
5.
Str
ip
W'
(13 mm)
of
in
sulation from
the
ends
of
all the wires. Secure
the
valve common wire
to
one
of
three C (Common) terminals located
of
the
Power and Accessory terminals. All three common terminals are
active,
so
the valve common wire may
be
connected
to
either one.
Attach all the individual valve control wires
to
the appropriate station
terminals.

Connecting a Master Valve or Pump Start Relay
Complete
this section only
if
you have a Master Valve
or
P
ump
Start
Re
lay
installed. The I-Core controller works with a normally closed master valve
that
is
typically installed at the supply
point
of
the main line that opens only
when
the
automatic system
is
activated. A
pump
start relay
is
an
electrical
device
that
uses the irrigation controller
to
activate a
pump
to
provide
water
to
your system.
The Master Valve
or
Pump Start
Re
lay connection
is
located on
the
bottom
row
of
the
Power and Accessory Terminals, and
is
labeled P/
MV.
This terminal will supply 24 VAC, 0.32A max, for a single Master Valve
solenoid. For a Pump Start
Relay,
the
relay holding current draw must
not
exceed 0.28 amps.
If
using a
Pu
mp
Start
Relay,
it
is
recommended
that the controller be
mounted
at least 15'
(4
.5
m)
away from
both
the
pump
start relay and
the
pump. When a
pump
is
to
be
operated
by
the controller, a
pump
start relay must
be
used.
Do
not
connect the
controller directly
to
the
pump
-
damage
to
controllBr will result.
1.
Route valve wires between Master Valve
or
Pu
mp
Start Relay location
and
the
controller.
2.
At
the Master Valve, attach a common wire
to
either solenoid wire
of
the valve. Attach a separate control wire
to
the remaining solenoid
wire.
At
the
Pump Start
Relay,
attach either wire
to
one
of
the yellow
wires coming from
the
Pump Start Relay. Attach the remaining wire
to
the
other
yellow wire at the
Relay.
All wire splice connections should
be
done
using waterproof connectors.
3.
Open
the inner facepack
door
at
the
controller.
4. Route the valve wires into
the
controller via
the
field
wire conduit.
5.
Connect either wire from the Master
Va
lve
or
Pump start Relay
to
the
P
/MV
terminal located on
the
bottom
row
of
the Power and Accessory
terminals. Connect the remaining wire
to
the C (Common) terminal
that
is
located directly
to
the left
of
the P/MV terminal.
The Master Valve
or
Pump Start Relay can
be
activated according
to
a
particular station. The configuration
of
assigning
the
Master Valve
or
Pu
mp
Start Relay according
to
a particular station will
be
covered
in
the
Set Pump
Operation (pg. 18).
