Connecting The Valves - Toro GreenKeeper 212 User Manual

Connecting the Valves

1. Route the valve wires or wire cable from the valves,
into the controller cabinet.
Note: Using 18 AWG (1mm
valve connection cable is recommended. This cable
is insulated for direct burial and is color-coded to
simplify installation.
2. Attach the white color-coded wire from the cable to
one wire from each valve solenoid. (Either solenoid
wire can be used for this connection.) This is called
the valve common wire.
3. Attach a separate cable wire to the remaining wire
from each valve solenoid. Make a note of the wire
color code used for each valve and the watering sta-
tion it controls. You will need to have this information
when connecting the valve wires to the controller.
4. Secure all wire splices using twist-on wire connectors.
To prevent corrosion and possible short circuits, use
a grease cap or similar waterproofing method to insu-
late each connection.
5. Strip back 1/2" (13mm) of insulation from all cable
wires at the other end of the valve connection cable.
Note: The GreenKeeper 212 has snap-in wire termi-
nals. To attach wires, simply raise the lever, insert the
stripped wire, and press the lever down to secure.

6. Referring to the Controller Components on page 5 and
the diagram above, secure the valve common wire to
the terminal labeled COM (12). Connect the individual
station valve wires to the appropriate station module
terminals (15). Connect the master valve wire (if
applicable) to the terminal labeled PUMP/MV (13).
Note: Connecting a master valve or pump start relay
is optional and may not be required in your sprinkler
system.
