LogicPLUS-S Two-Wire Controller

inSTALLinG The LogicPLUS-S

Mounting the controller...........When selecting the controller installation location,

make sure control-

ler and all related wiring is a minimum of 15 feet from any high voltage control boxes, pumps

or any high voltage equipment. This irrigation controller is a computer and should be installed

accordingly. When mounting the LogicPLUS-S indoors, notice the “keyhole” shaped mounting slot

as well as 2 mounting holes on the back of the controller. Use the template provided to locate mount-

ing screw locations. Remove the four face plate screws and two lower panel screws to access enclo-

sure mounting screws. To attach to wall studs, use a #10 screw, leaving 1/4” of the shank exposed to

slip into the “keyhole” slot. To additionally secure the controller, drive additional screws through the

bottom mounting holes into the stud or cross bracing.
When mounting the LogicPLUS-S outdoors, use the same procedure as above. When attaching

the controller to hollow walls, masonry, or cinder blocks, use appropriate toggle bolts, masonry shields

or compression drive bolts. For additional weatherproofing, run a silicon bead around the case be-

tween the controller and the wall. It is also recommended to fill mounting holes with silicon as well, to

prevent water or insects from entering the controller.

The LogicPLUS-S should be hard wired to power supply the by a qualified electrical technician.

Use an approved GFi device and utilize proper grounding techniques using the green wire

from controller transformer. This will help assure safety as well as performance and reliability

of the LogicPLUS-S controller. The manufacturer’s warranty becomes invalid without proper

grounding as per local code. See enclosed “installation diagram for Primary Wiring.” Warn-

ing! When connecting the field receivers, make sure there is no power to the printed circuit

board, controller and/or the receivers; this will prevent the shorting of receivers and controller.
Unscrew the LogicPLUS-S bottom terminal plate and route the field wires (one to four sets) through

the hole at the bottom of the controller. Secure each 2-wire run under the appropriate terminal on the

terminal strip labeled

“Line 1,” “Line 2,” “Line 3,” “Line 4.” If using multiple outputs, keep each 2

wire set independent.

do not mix output “Line 1” with output “Line 2,” “Line 3” with “Line 4” or any

other combination. It is strongly suggested to use different colored wires for each wire used.

To easily test for communication and wire integrity, connect each receiver to the field wiring at each

planned location. It is not necessary for receiver to be attached to solenoid/valve for test, but O.K. if

already connected. Do not allow black receiver wires to touch each other (short or ground) when test-

ing. Manually sequence controller through each station number for minimum of 30 seconds, checking

each activated receiver in the field for a continuously activated bright LED light on each receiver. A

continuously activated bright LED light on receiver during station activation confirms satisfactory com-

munication.
Please read the entire operational manual before installing and programming the LogicPLUS-S

Controller.
