4. CONTROLLER WIRE CONNECTION
The 720A, 740A and the 760A controllers have a set of red wires numbered for each valve
as well as one black wire for master valve, two white wires for common, and one looped
yellow wire “S” for a rain sensor connection.
4.1 CONNECTING THE WIRES:
1. Connect each numbered red wire to a corresponding red DC solenoid wire (DIG model
#S305DC DC latching solenoid recommended).
2. Connect each white solenoid wire to
one of the two common white wires
from the controller using waterproof
splice connectors (Figure C).
NOTE: If a master valve is installed and
set to active, it will operate and open
with the first valve and will close with
the last valve.
WARNING: Do not strip the master
valve or sensor wires unless using a
master valve or rain sensor.
3. After installation, test each valve via the
solenoid by turning the solenoid one or two turns counterclockwise to open and clockwise
to close. If a valve remains open via a manual operation, you may need to examine the
solenoid and the adapter used to see that they are installed correctly. Make sure the
adapter and the solenoid are firmly secured but not over tightened.
WARNING: If using valves with built-in internal manual bleed levers: make sure
the lever is in the auto (closed) position. Do not move the manual lever after
installing the adapter and solenoid.
