Connecting the Valves

Note: Using 14 to 18 AWG (2.5mm2 to 1mm2) irrigation cable is recommended. This cable is made specifically for automatic irrigation systems and is available in several lengths and conductor count. Always use a cable that has at least one wire for each valve and one wire for the valve common connection.

1.Route the wire cable from the valve location into the controller cabinet.

2.Attach the white (preferably) cable wire to either wire from each valve solenoid. This is called the valve common wire.

Note: The solenoid does not have specific polarity, so either wire can be used for the common wire connection.

3.Connect an individual color-coded cable wire to the remaining solenoid wire of each valve. Make a note the wire insulation color used for each connection and the sprinkler zone controlled by the valve.

IMPORTANT: To prevent possible short-circuit conditions causing controller damage, properly connect, insulate and waterproof all wire splices.

4.Remove 1/2" (13mm) of insulation from the end of all cable wires to be connected to the controller.

Note: The station module has snap-in wire connectors. To attach wires, simply raise the lever and insert the bare wire end into the small hole beneath the lever. Press the lever down to secure the wire. Pull lightly on the wire to confirm that it is locked into the module.

5.Referring to the Controller Components on page 5 and the diagram above, secure the valve common wire to the terminal labeled COM (8). Connect the individual valve wires to the appropriate expansion module ter- minals (11). The stations are numbered from left to right, 1 through 12. Connect the master valve wire

(if applicable) to the terminal labeled PUMP/MV (9).
