Lawn Genie LD6 - CO M/R IRRIGATION 6 Zone Controller Timer Operator's Manual page 9

Do not plug transformer into power source until the
controller is mounted and ALL valves have been
connected.
3. If you have not already done so, connect a 9-volt alkaline
battery clip. DO NOT use a rechargeable battery. The display
will illuminate under normal conditions. If any unexpected
display characters show, simply disconnect and reconnect the
battery. After a few minutes the display will go blank under
battery power. Turn dial to illuminate display. The battery is
designed as a memory retention feature only. Valves will only
operate with power supplied by the transformer.
Connecting the Valves & Transformer
DO NOT try to connect the controller directly to an outlet. This
WILL destroy the controller and may result in electric shock or fire
hazard. Please use only single strand multi-colored irrigation wire
for your installation.
1. Connect the transformer wires to the two screws marked AC.
Do not plug in transformer until after all valves have
been connected.
2. Connect valve #l wire to screw marked 1 and the "valve
common" wire to main common wire which feeds back to the
controller. Typically, you will have all of your valves grouped
together. From this valve group you will send your multi-
colored wire bundle back to the controller. Then, the single
common wire is connected to the common terminal screw
marked C. (See diagram.) In some cases, you may have more
than one common wire. One from the front yard and one from
the back yard. All commons get connected to the terminal
screw marked C. If a number of commons are required, you
may need to use a "wire nut" to combine these commons
together with a lead wire. The single lead wire is then
connected to the common terminal screw marked C. Back
screw out until head is 1/8" above plastic partition. Bend bare
copper wire in clockwise hook (only expose l/2" of bare
copper from end of wire to reduce short circuiting of two
adjacent wires). Slip wire hook under screw head and tighten
screw until wire is secure.
3. Repeat step 2 for all valves.
