INSTALLING THE LOGIC
Mounti ng the controller. . .When sele ting the controller installation location, make
sure controller 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 LOGIC 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 mounting screw locations. Remove the four face plate screws
and two lower panel screws to access enclosure 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 LOGIC 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 between 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 LOGIC should be hard wired to the transformer 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 Logic controller.
The manufacturer’s warranty becomes invalid without proper grounding as
per local code. See enclosed “Installation Diagram for Primary Wiring”.
Warning! 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 LOGIC bottom terminal plate and route two (or four) field wires
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” and “Line 2”. If using
both outputs “Line 1” and “Line 2”, keep each 2 wire set independent. Do not mix
output “Line 1” with output “Line 2”. It is strongly suggested to use different
colored wires for each wire used.
The Logic 2 and Logic 3 Terminal Strip is labeled as follows:
