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.

User Interface Table .5 LCM Button Functions Button Function Mode Select between Run and Setup Modes. 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 psi (138 MPa, 138 bar) Arrows Up/Down Navigate up or down within a screen or to a new screen.
Display Components The following tables identify components shown on the spray mode active, circulation mode active, alarm active, and deviation active run screens. For more information see Run Mode Details, page 25. Table .6 Display Components Icon Function Actual spray pressures Differential pressure alarm bar graph Selected pressure units.

Installation Topics Covered in this Chapter ♦ ♦ ♦ ♦ ♦ Location Install Air Solenoid Install Electronics Box and LCM Install Pressure Transducers Connect Air Hoses and Cables 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.
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.
Connect Air Hoses and Cables Reference 262940 Line Power Kit, page 4 and 262942 Air Turbine Kit, page 5 for air hose and 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.
Advisories and Alarms Topics Covered in this Chapter ♦ ♦ ♦ ♦ Clear Alarms View Current Alarms View Error Log Error Codes The following table explains the error type that is associated with the particular light tower LED. Light Tower LED Description Green Solid System is powered up and monitoring pressure. Yellow Solid In Circulation Mode or Manual Bypass Mode There are three types of errors that can occur. Errors are indicated by the light tower as well as on the display.
View Error Log Setup Screen 3 is the error log screen. It displays the most recent error on the top of the list with the past three errors below it. This screen displays a list of advisory or alarm error codes and the time the error occurred since the kit was powered on.

Repair Topics Covered in this Chapter ♦ Replace LCM Tear Off Sheet ♦ Replace Switch Fuses ♦ Replace Filter Element ♦ Replace Alternator or Turbine Cartridge For system specific repair procedures, refer to your XP Sprayer instructions-parts manual. Replace LCM Tear Off Sheet The LCM is supplied with 10 protective tear off sheets that prevent spray material from covering the LCM display. 1. Peel away the dirty protective sheet. 2. Install a new protective sheet (68) on the LCM display.
Replace Alternator or Turbine Cartridge For 262942 only. Turbine alternator cartridge 257147 (34e) can be replaced in alternator 262579 (34). 1. Turn off air supply. 2. Close ball valve (22). 3. Remove box cover (30). 10. Reassemble. Note • Lightly lubricate turbine o-ring before installing turbine in housing. • Align ribbon connector and firmly press the cartridge into the top housing. • Connect turbine to 3–pin connector on main circuit board. • Torque housing screws evenly to 18 in.-lbs (2 N•m).
