Connect Valve Wires To Timer; Wiring Electric Valves; Common Wire - Orbit 27894 Abridged User Manual

3. Connect Valve Wires to Timer

• Strip 1/2" (12 mm) of the plastic insulation off the end of
each wire for both the timer wires and the valve wires
• Connect one wire from each valve (it doesn't matter
which wire) to a single "Common" sprinkler wire (usually
white)
• Connect the remaining wire from each valve to a
separate colored sprinkler wire
See figure 3
Note: The maximum loading for each station/pump is 250mA,
the maximum loading for the timer is 500mA.
If the distance between the sprinkler timer and valves is under
700' (210 m), use Orbit sprinkler wire or 20 gauge (AWG) plastic
®
jacketed thermostat wire to connect the sprinkler timer to the
valves. If the distance is over 700' (210 m), use 16 gauge (AWG) wire.

Important: All wires should be joined together using wire nuts,
solder, and/or vinyl tape. In wet environments like a valve box it
is recommended to use Orbit Grease Caps to prevent corrosion of
the connection and for protection from water infiltration.

Wiring Electric Valves

Strip 1/2" (12 mm) of plastic insulation off the end of each
individual wire. Each valve has two wires. One wire (it doesn't
matter which one) is to be connected as the common. The

other valve wire is to be connected to the specific station wire
that will control that valve. The common wires for all the
valves can be connected together to one common wire going
to the controller. To avoid electrical hazards, only one valve
should be connected to each station. See figure 4
Important: The wire can be buried in the ground; however, for more
protection wires can be pulled through PVC pipe and buried under-
ground. Be careful to avoid burying the wires in locations where
they could bedamaged by digging or trenching in the future.
Your timer is equipped with the simple "push-in" terminals for
easy connection. Connect common wire to the common terminal.
Connect remaining wires to corresponding terminal locations.
Only connect one valve to
each terminal (station)
