Connecting The Valves - Toro TMC-212 Manual Del Usuario

Connecting the Valves

1. Route the valve control wires between the valves and
the controller.
Note: The station modules and wire connectors accept
14–18 AWG (2.5–1.0mm
Sprinkler system connection cable is recommended.
2. Attach the white-color cable wire 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. Route the wire cable into the controller through the
large opening in the base of the housing or through
PVC conduit if it is installed. Strip insulation back
1/2" (13mm) from all cable wires.
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.

6. 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
station valve wires to the appropriate station 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.
