Connecting The Valves - Toro ECXTRA Sprinkler Timer User Manual

Connecting the Valves
1. Route the valve control wires between the valves and
the timer.
Note: The snap-in wire connectors accept 14–18
gauge (2mm –1mm ) wire. Using direct-burial irrigation
2 2
cable is recommended. Choose a cable that has at
least one additional wire conductor than the number of
valves to
be connected.
2. Attach the white color-coded wire to either one of
the wires from each valve solenoid. This is called the
valve common wire.
3. Attach an individual color-coded wire to the remaining
wire from each valve solenoid. Make a note of the wire
color used for each valve and the watering zone it con-
trols. You will need this information when connecting
the valve wires to the timer.
CAUTION: Use Toro Waterproof Wire Connectors
(Model # 53687) or grease caps on all exposed wire
splice connections to prevent corrosion, connection
failure and possible short circuit.
4. Route the wire cable into the timer through the large
opening in the base of the housing, or through PVC
conduit (if installed). Strip insulation back 3/8" (9mm)
from all wires being used.
Note: The zone module has snap-in wire terminals.
To attach wires, simply raise the lever, insert the
stripped wire, and press the lever down to secure.

5. Referring to "Timer Components" on page 5 and the
diagram above, connect the valve common wire to
the terminal labeled "COM" (10). Connect the individ-
ual zone valve wires to the appropriate zone module
terminals (11). Connect the master valve wire
(if applicable) to the terminal labeled PUMP/MV (9).
Note: Connecting a master valve or pump start relay
is optional and may not be required in your sprinkler
system.
