OverviewOverviewOverviewThe purpose of the pressure monitor kit is toshutdown the sprayer if abnormal pressure conditionsare detected to prevent spraying material that is notmixed on ratio.
Two pressure transducers are added to read the Aand B fluid pressures in the outlet manifold and sendthe readings back to the Local Control Module (LCM).
The control watches the difference between the A andB pressures. The control will alarm if the pressuressplit because of a plug, leak, or running out of fluid.
When an alarm indicates that the sprayer may beoff ratio, the air solenoid shuts off the air supply tothe proportioner motor. The light tower will indicatean alarm has occurred, and the alarm code willbe on the LCM display. For more information seeAdvisories and Alarms.
The following alarms can occur:
• Differential Pressure (B>A)• Differential Pressure (A>B)• Pressure A High• Pressure B High• Air Solenoid Disconnected• Pressure A Disconnected• Pressure B Disconnected
The air motor is allowed to automatically operate inCirculation Mode with a yellow light anytime the fluidpressures are below the minimum spray pressure.This allows for loading the system and circulating thefluids without alarms or shutdowns.
When the control sees the fluid pressures above theminimum spray pressure for 3–30 seconds, and thepressures are balanced within the pre-set limits, itwill automatically start the monitor mode, and thegreen light on the light tower will change to solidon. If the control does not see balanced pressureswithin 30 seconds of going above the minimum spraypressure, it will alarm and shut off the air motor. Thedefault minimum spray pressure is 2000 psi (14 MPa,138 bar). Enter Setup Mode to change the minimumspray pressure as necessary.
The control will alarm and shutdown if it sees either Aor B above the maximum working pressure of 7250psi (50 MPa, 500 bar). Enter Setup Mode to reducethe maximum allowable pressure set point.
Spray Start and stop the air motor. Themotor will stay on indefinitely ifpressures are below minimumspray pressure. Monitor modewill start within 30 seconds if thepressures are above the minimumspray pressure and no errorsexist. All errors are ignored for 30seconds. Default is 2000 psi (138MPa, 138 bar)

Installation
InstallationInstallationInstallation
Shutdown the XP Sprayer before installing yourpressure monitor kit. Follow the ShutdownShutdownShutdown andPressurePressurePressure ReliefReliefRelief ProcedureProcedureProcedure in the XP Sprayeroperation manual. All electrical wiring must bedone by a qualified electrician and comply with alllocal codes and regulations.
The procedures in this section are specific to eachcomponent of the pressure monitor kit. For sprayerinstallation instructions, refer to the XP70 SprayerOperation manual or the XP-hf Operation manual. .
LocationLocationLocation
These pressure monitoring kits are not approvedfor use in hazardous atmosphere locations.
Installing this kit on an XP Sprayer or an XP-hfProportioner that is EX approved, voids theapproval. The EX mark should be removed fromthe machine ID plate when this kit is installed.
NOTICENOTICENOTICEDo not store a XP Sprayer with a pressure monitorkit outside in the rain. Use protective bag 16J717to prevent damage to the electronic components,used with the pressure monitor kit, when storedoutside.
1. Disconnect the upper swivel and remove themotor air line from the lower air manifold.
NOTE:NOTE:NOTE: On early XP sprayers, to remove theexisting air hose, it may be necessary to removethe air filter assembly from the XP and put itin a vice. New models XP sprayers have anadditional hose union.
2. For the turbine powered kit 262942, remove aplug from the air manifold and install the 5/16 in.x 4 ft (1.2 m) air hose.
Figure 83. Connect the air solenoid valve and new motor
air hose to the air inlet assembly. Ensure thatthe air solenoid valve cable faces the back ofthe machine.
1. Use three screws (61) and three nuts (62) tomount the box bracket to the cart (as shown inthe figure below). For XP systems with an XL airmotor, mount the box bracket on the oppositeside of the cart.
NOTE:NOTE:NOTE: Nuts are not used on newer carts withnuts crimped onto the cart plate.
2. For line power kits, install the appropriatepower supply cord(s). US, European, andAustralia/Asia cord adapters are supplied. SeeTechnical Data, page 28.
1. Remove plugs from the circulation fluid manifold.
NOTE:NOTE:NOTE: Keep the plugs to reuse if you everremove the pressure monitor kit.
2. Connect pressure transducer (4), with blue#6 label, with black o-ring (13) to the A sideof the circulation manifold. Connect pressuretransducer (4), with red #7 label, with black o-ring(13) to the B side of the circulation manifold.Tighten to 40–50 ft-lb (54–67 N•m) beforeapplying fluid pressure.
Use tie wraps provided to secure hose and cables.For air turbine kits, route exhaust hose (41) downcart leg and secure.

Startup
StartupStartupStartup1. Refer to the XP Sprayer or XP-hf Proportioner
Operation manual for sprayer startup instructions.
NOTE:NOTE:NOTE: The pressure monitor kit does not changethe operation procedures in the XP Sprayer orXP-hf Proportioner Operation manual.
2. Turn on power.
a. For Line Power Kits: Turn on power switch(9) located on the electronics box.
b. For Air Turbine Kits: Open ball valve (22)located outside of the electronics box.
NOTE:NOTE:NOTE: The air pressure regulator should beset at 22 +/- 5 psi (.15 +/- .03 MPA, 1.5 +/-3 MPa).
3. Wait for the power up screen to complete. TheCirculation Mode screen will display. The lighttower will briefly flash green, yellow, and red toverify the lights before staying on yellow. Wait forthe run screen to appear.
4. Set system parameters before spraying.These can be changed as necessary.
Press to enter Setup Mode. Formore information and default settings, seeAppendix A— User Interface Display, page 22.
5. In Circulation Mode, all alarms are disabledexcept for the air solenoid detection, pressuresensor failure, and high pressure alarms.
NOTE:NOTE:NOTE: In Manual Bypass Mode you can stillspray when one pressure transducer fails, butthe control no longer monitors the pressures andwill not shut off the sprayer. This is for temporaryuse only to complete the job.
a. To enter Manual Bypass Mode, set theminimum spray pressure equal to themaximum spray pressure on setup screen2. In Manual Bypass Mode, the system cannever get into Spray Mode. The event codeEVC1 is displayed on the information screenand logged in the error log. The yellow lightis always on and all alarms are ignored.
b. To exit Manual Bypass Mode, set theminimum spray pressure and maximumspray pressure to different spray pressures.Event code EVC0 will log in the error logwhen Bypass Mode is disabled.
6. Press to start the air motor. The red LEDwill turn on and the motor will start. Only spraywhen the green light on the light tower is on. Formore information about the LCM run screens,see Run Mode Details, page 25.
ShutdownShutdownShutdown
1. Press . The red LED will turn off and themotor will stop.
2. Turn off the power switch or ball valve on theoutside of the electronics box.

In normal spray conditions, the B pressure is 300psi above the A pressure. The bar graph is offsetto one side.
Enter a B offset pressure of +300 psi. Now the bargraph Is centered.
The differential pressure alarm now sees nodifferential when the B pressure is 300 psi higherthan the A pressure. If the B pressure was normally300 psi lower than the A pressure, you would enter—300 psi to balance the offset.

The bar acrossthe bottom indicates the magnitude of the differentialpressure with respect to the alarm setpoint. InCirculation Mode, all alarms are disabled except forthe Air Solenoid Detection High Pressure A, and HighPressure B alarms
If the user needs to spray with one of the aboveerrors active, set the Lower Spray Pressure Limitequal to the High Pressure Alarm Limit to enterManual Bypass Mode. Only use Manual BypassMode for emergency operation to finish the job. Thecontrol no longer monitors the pressures and will notshut off the sprayer.
Indicates that you are in CirculationMode and the fluid pressure is belowthe Lower Spray Pressure Limit.
All alarms are disabled except for AirSolenoid Detection, High PressureA, and High Pressure B alarms. Theyellow light on the light tower will besolid on.
This screen will also be used when inManual Bypass Mode.
