Connecting an Earth Ground

CAUTION: The built-in circuit protection in all Turf Pro controllers
must have an earth ground path to help protect the controller from
power surges. This is especially important in lightning-prone areas.

A 12 gauge (2.0 mm ) solid copper ground wire must be connected to
the ground
lug located on the controller's terminal board and a
ground source such as a copper-clad ground rod.
Connecting to the Valves
Route one valve solenoid lead from each valve through the large hole in the
bottom of the controller. Secure each wire to a separate numbered terminal.
Attach the remaining wire from each valve to a single common wire and
attach that wire to the "VC" (Valve Common) terminal.
CAUTION: Do not link
the common wire of two
or more controllers
together. Use a separate,
independent valve
common wire for each
controller. Linking two or
more controllers with a
single common wire can
cause disruptions or even
serious product damage.
Note: This controller is
designed to work with
24 V a.c., 0.25A (6 VA)
solenoid operated valves.
A maximum of two
solenoids per terminal may
be used (not to exceed
0.5A per station), and no
more than three solenoids
should be on at any one
time plus the master valve
and/or pump start, if one is
being used. Load
requirements must not
exceed 1.0A maximum
total current draw.
