Toro ECXTRA manual Connecting the Valves

 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 (2mm2–1mm2) wire. Using direct-burial irrigation 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.
