Pump Start Wiring
Wiring a pump start is easily accomplished if you follow a few basic steps. First, be
sure to have a proven wiring diagram available for the particular situation you are
wiring. Next, any Class 1 wiring (above 30 VAC) must be installed by a licensed electrician. Last, if you are not experienced in pump start wiring, find someone who knows
how to install a pump start and learn the basics from them before you attempt to install
one by yourself.
Warning! Any pump start relay wired to an irrigation controller should have
all unused station wires connected to the last used station wire. See Figure
7.
The following diagrams show wiring details for pump start relay and pump motor
starter wiring for various Rain Bird controllers.

This is a basic pump start wiring diagram for most controllers. This diagram assumes
the Master Valve circuit is being utilized for the pump start circuit.

Figure 2:
You cannot install more than one controller to a pump start relay. You can however,
install multiple relays to one pump starter. This diagram is for installing two or more
controller relays to one pump starter, and any controller can operate at any time with
any other controller already operating.
Warning!: Be sure to allow for enough hydraulic supply, if multiple controllers
can operate at the same time.

Figure 5:
This wiring diagram shows us the wiring for four controllers wired to one pump starter,
and one Common wire for all valves on all four controllers. If more than one controller
is in operation at the same time, Controller A takes precedence over Controllers B, C
and D; Controller B will take precedence over C and D; Controller C will take precedence over Controller D.

Figure 6:
This diagram shows how to wire a pump start relay with a pressure switch. The pressure switch will turn on the pump any time the pressure falls below the preset low
pressure limit. The controller will turn on the pump when a irrigation start is initiated,
whether the pressure switch is active or not.

Any time you wire a pump start relay to a controller, you must wire all unused stations

Operating Instructions:
All stations operating with the pump must be grouped together ahead of control station
"X." When station "X" turns on, the pump is turned off. The pump stays off for all remaining stations in the cycle. When the last station turns off, the pump relay is reset to
operate with the next irrigation start. The pump operates with stations 1 through "X - 1"
and is off with stations X through the last station.
Example: ISC - B + -12 with the pump on for stations #1 through #4 and off with stations #5 through #12. Station #5 is control station X and turns the pump off when the
controller turns on Station #5. When the cycle is complete (all 12 stations have operated), the pump start relay is reset to start the pump at the next irrigation start.

Master Valve Wiring
When wiring multiple controllers to a Master Valve, the controller Master Valve circuits
must be isolated from each other. The following diagrams illustrate how to install relays for multiple controller installations.
Figure 10:
This diagram illustrates the wiring for installing two controllers with one Master Valve.
A Rain Check or Aquamiser device for each controller is also shown. If the Rain
Check or Aquamiser device is not installed, the common wire should be wired to bypass the unit in the diagram.

Multiple Controller Wiring
(Common Wire Isolation)
Wiring multiple controllers on a single project requires the common wire to be separated from each of the controllers. The following diagrams illustrate how to wire these
types of installations.
Figure 12:
This wiring diagram shows how to wire two controllers to one common wire.
OPERATION:
CONTROLLER #1 HAS PRIMARY CONTROL OF THE SYSTEM.
WHEN IT IS ON. THE 2nd. CONTROLLER WILL BE AUTOMATICALLY DISCONNECTED FROM THE FIELD COMMON. IF CONTROLLERS OPERATE AT THE SAME TIME. ONLY VALVES ON
THE #1 CONTROLLER WILL OPERATE.

Wiring sensors is quite simple. The following wiring diagrams will assist you
in wiring most common types of sensors.

Remote Control Isolation Wiring
Wiring a remote control device (Remote Bird) to some electromechanical controllers
(RC Series controllers) requires an isolation relay to allow the remote controller to operate properly.
