If your sprayer is equipped with an electric relief solenoid
valve, follow these instructions to ensure proper installation
and operation.
With the addition of the optional Relay Kit, if at least one
boom is ON, the relief valve will be closed. If all booms are
OFF, the relay will open the relief valve, providing bypass of
the spraying solution.
WIRING INSTRUCTIONS
1. Fasten the supplied relay in a suitable location. Use a
self-tapping screw or other suitable fastener to secure
the relay in place.
2. Connect one solenoid terminal to the relay terminal
marked number “5” (normally open relay terminal). The
other solenoid terminal connects to ground.
NOTE: Exact proportion has been
altered to em pha size detail.

Relief Valve
he relief valve is used to divert flow around the servo when
your boom valves are turned off. Whenever all the boom
control switches are turned off, the relief valve should be
open. Use this plumbing illustration (See Illustration 16) as
your pattern for proper installation if your relief valve has a
flow-through port. DO NOT install the relief valve closer than
12” to the flowmeter. You will need to purchase an optional
relay kit to use the relief valve option. Installation of this relay
kit is explained on page 17.
If your relief valve does not have flow-thru port, you must
add a “T” fitting. See Illustration 17.
NOTE: To assure a good con nec tion and avoid corrosion,
coat so le noid lugs with sil i cone grease.

3. Connect the orange wire already attached to the relay
terminal marked number “3” (common relay terminal),
to a 12-Volt source.

to relay terminal number “2”. Then clamp the supplied
quick disconnect wire tap over the 9” RED wire (Pin
B) of the MT-2400 Speed, Run/Hold power harness,
and snap the female spade terminal over the wire tap.
See Illustration 18.
