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

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.
8 3A1331C
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.

cable connections.
Use tie wraps provided to secure hose and cables.
For turbine kit 262942, route exhaust hose down cart
leg and secure.
• 262942: Secure solenoid cable (F) to air hoses
with tie wrap. Route exhaust hose (J) down the
inside of the cart leg and secure with tie wrap.
• 262940: Route solenoid cable (F) behind the air
hose and secure with tie wrap.
Startup
1. Refer to your XP Sprayer Operation manual for
sprayer startup instructions.
more information and default settings, see
Setup Mode Details, page 22.
5. In Circulation Mode, all alarms are disabled
except for the air solenoid detection, pressure
sensor failure, and high pressure alarms.
Note
In Manual Bypass Mode you can still
spray when one pressure transducer
fails, but the control no longer monitors
the pressures and will not shut off the
sprayer. This is for emergency only.
a. To enter Manual Bypass Mode, set the
minimum spray pressure equal to the
maximum spray pressure on setup screen
2. In Manual Bypass Mode, the system can
never get into Spray Mode. The event code
EVC1 is displayed on the information screen
and logged in the error log. The yellow light
is always on and all alarms are ignored.
Note
The pressure monitor kit modifies XP
sprayers. However, the operation
procedures from the XP sprayer
Operation manual still apply.
2. Turn on power.
a. For 262940: Turn on power switch (9)
located on the electronics box.
b. For 262942: Open ball valve (22) located
outside of the electronics box.
3. Wait for the power up screen to complete. The
Circulation Mode screen will display. The light
tower will briefly flash green, yellow, and red to
verify the lights before staying on yellow. Wait for
the run screen to appear.
4. Set system parameters before spraying.
These can be changed as necessary.
Press
to enter Setup Mode. For
b. To exit Manual Bypass Mode, set the
mimimum spray pressure and maximum
spray pressure to different spray pressures.
Event code EVC0 will log in the error log

down the machine. If the machine
shuts down too easily, increase this
to a higher setpoint.

Only used for remote mix manifold
applications where there is a normal

Remote mix manifold applications
should first be balanced with proper
hose sizing and adjusting the mix

3A0590.
Use if your differential alarm bar
graph on the Spray screen is off
to one side under normal spray
conditions.
See B Side Pressure Offset Example.
B Side Pressure Offset Example
In normal spray conditions, the B pressure is 300
psi above the A pressure. The bar graph is offset
to one side.

Enter a B offset pressure of +300 psi. Now the bar
graph Is centered.
The differential pressure alarm now sees no
differential when the B pressure is 300 psi higher
than the A pressure. If the B pressure was normally
300 psi lower than the A pressure, you would enter
—300 psi to balance the offset.

Run Mode Details
Spray Mode Active
There are four Run Screens: Circulation Mode
Active, Spray Mode Active, Alarm Active, and
Deviation Active.
Circulation Mode Active
This is the run screen that appears after the power up
screen. A and B pressure are shown. The bar across
the bottom indicates the magnitude of the differential
pressure with respect to the alarm setpoint. In
Circulation Mode, all alarms are disabled except for
the Air Solenoid Detection High Pressure A, and High
Pressure B alarms
If the user needs to spray with one of the above errors
active, set the Lower Spray Pressure Limit equal
to the High Pressure Alarm Limit to enter Manual
Bypass Mode. Only use Manual Bypass Mode for
emergency operation. The control no longer monitors
the pressures and will not shut off the sprayer.
This is the run screen that appears during spray
mode. A and B pressure are shown. The bar across
the bottom indicates the magnitude of the differential
pressure with respect to the alarm setpoint.
When the pressure first gets above the lower spray
pressure limit, the user has 30 seconds to balance
the system differential pressure so it is less that the
differential pressure deviation and alarm limits. Then
the system will automatically go into Spray mode and
start monitoring all alarms and deviations.
