Toro ECXTRA manual Connecting the Valves, Zone, Valve Common, Master, Wire

 Connecting the Valves

1.Route the valve wires or wire cable from the valves, into the timer cabinet.

Note: The snap-in wire connectors accept 14–18 gauge (2mm2 to 1mm2) wire. Using direct-burial irriga- tion cable is recommended. Choose a cable that has at least one more 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 controls. You will need to have this information when connecting the valve wires to the timer.

CAUTION: To prevent corrosion, connection fail- ure and possible short circuit, use Toro waterproof wire connectors (Model # 53687) or grease caps on all exposed wire splice connections.

4.Route the wire cable into the timer through the large opening in the base of the housing or through PVC conduit (if it is installed). Strip insulation back 3/8″ (10mm) from all cable wires.

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 the Timer Components on page 5 and the diagram above, secure the valve common wire to the terminal labeled COM (10). Connect the individual zone valve wires to the appropriate zone module terminals (11). Connect the master valve wire (if appli- cable) 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.
