Overview
Operating Window
Below Minimum Spray Pressure
Topics Covered in this Chapter
♦ Operating Window
The purpose of the pressure monitor kit is to
shutdown the sprayer if abnormal pressure conditions
are detected to prevent spraying material that is not
mixed on ratio.
Two pressure transducers are added to read the A
and B fluid pressures in the outlet manifold and send
the readings back to the Local Control Module (LCM).
The control watches the difference between the A and
B pressures. The control will alarm if the pressures
split because of a plug, leak, or running out of fluid.
When an alarm indicates that the sprayer may be
off ratio, the air solenoid shuts off the air supply to
the proportioner motor. The light tower will indicate
an alarm has occurred, and the alarm code will
be on the LCM display. For more information see
Advisories and Alarms, page 11.
The following alarms can occur:
• Differential Pressure (B>A)
The air motor is allowed to automatically operate in
Circulation Mode with a yellow light anytime the fluid
pressures are below the minimum spray pressure.
This allows for loading the system and circulating the
fluids without alarms or shutdowns.
Above Minimum Spray Pressure
When the control sees the fluid pressures above the
minimum spray pressure for 3–30 seconds, and the
pressures are balanced within the pre-set limits, it
will automatically start the monitor mode, and the
green light on the light tower will change to solid
on. If the control does not see balanced pressures
within 30 seconds of going above the minimum spray
pressure, it will alarm and shut off the air motor. The
default minimum spray pressure is 2000 psi (14 MPa,
138 bar). Enter Setup Mode to change the minimum
spray pressure as necessary.
Maximum Spray Pressure
The control will alarm and shutdown if it sees either A
or B above the maximum working pressure of 7250
psi (50 MPa, 500 bar). Enter Setup Mode to reduce
the maximum allowable pressure set point.
• Differential Pressure (A>B)
• Pressure A High
• Pressure B High
• Air Solenoid Disconnected
• Pressure A Disconnected
• Pressure B Disconnected

Spray Start and stop the air motor. The
motor will stay on indefinitely if
pressures are below minimum
spray pressure. Monitor mode
will start within 30 seconds if the
pressures are above the minimum
spray pressure and no errors exist.
All errors are ignored for up to the
first 30 seconds. Default is 2000

Installation
Topics Covered in this Chapter
♦ Location
♦ Install Air Solenoid
♦ Install Electronics Box and LCM
♦ Install Pressure Transducers
♦ Connect Air Hoses and Cables
Shutdown the XP Sprayer before installing your
pressure monitor kit. Follow the Shutdown and
Pressure Relief Procedure in the XP Sprayer
operation manual. All electrical wiring must be
done by a qualified electrician and comply with all
local codes and regulations.
The procedures in this section are specific to each
component of the pressure monitor kit. For sprayer
installation instructions, refer to the XP70 Sprayer
Operation manual.
Install Air Solenoid
1. Disconnect the upper swivel and remove the
motor air line from the lower air manifold.
Note
On early XP sprayers, to remove the
existing air hose, it may be necessary to
remove the air filter assembly from the
XP and put it in a vice. New models XP
sprayers have an additional hose union.
2. For the turbine powered kit 262942, remove a
plug from the air manifold and install the 5/16 in.
x 4 ft (1.2 m) air hose.
Location
These pressure monitoring kits are not approved
for use in hazardous atmosphere locations.
Installing this kit on a XP Sprayer that is EX
approved, voids the approval. The EX mark should
be removed from the machine ID plate when this
kit is installed.
NOTICE
Do not store a XP Sprayer with a pressure monitor
kit outside in the rain. Use protective bag 16J717
to prevent damage to the electronic components,
used with the pressure monitor kit, when stored
outside.
Figure 8
3. Connect the air solenoid valve and new motor
air hose to the air inlet assembly. Ensure that
the air solenoid valve cable faces the back of
the machine.

Install Electronics Box and LCM
Early XP carts have two mounting holes and new XP
carts have three mounting holes. Complete steps 1
and 2 to drill a third mounting hole for the pressure
monitor kit. Complete step 2 if you have a new XP
cart.
1. Early XP carts with two mounting holes
a. Use two screws (61) and two nuts (62) to
mount the electronics box to the top of the
cart.
b. Use a marker to mark the bracket’s third
mounting hole.
c. Loosen the nuts (62) below the cart shelf and
remove the screws (61), and box bracket.
Center punch and drill a 5/16 in. hole in the
top of the cart.
2. New XP carts with three mounting holes.
a. Use three screws (61) and three nuts (62) to
mount the box bracket to the cart.
b. For power supply kits, install the appropriate
power supply cord(s). US, European, and
Australia/Asia cord adapters are supplied.
See Technical Data, page 29.
