Overview Overview
The purpose of the XP PressureTrak is to shut down
the sprayer if abnormal pressure conditions are
detected in order to prevent spraying material that is
not mixed on ratio.
Two pressure transducers read the A and B fluid
pressures in the outlet manifold and send the
readings back to the XP PressureTrak.
The XP PressureTrak monitors the difference
between the A and B fluid pressures, alerting the
user when an imbalance is detected. An imbalance
may be due to a plug, leak, or running out of fluid.
When an imbalance is detected, the electric solenoid
disables the air motor, an alarm is displayed on
the screen, and the LED on the front of the display
flashes. For more error code information see
Alarms, Deviations, and Advisories, page
The following alarms can occur:
• Differential Pressure (B>A)
• Differential Pressure (A>B)
• Pressure A High
• Pressure B High
• Electric Solenoid Disconnected
• Pressure A Disconnected
• Pressure B Disconnected
• Low Battery
• Blown Fuse

Operating Operating
Below Minimum Below Below Minimum Spray Minimum
The air motor is allowed to automatically operate in
Circulation Mode any time 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 Minimum Spray
Above Above Minimum
When the XP PressureTrak detects the fluid
pressures above the minimum spray pressure for
30 seconds, and the pressures are balanced within
the pre-set limits, it will automatically start pressure
monitoring. If the XP PressureTrak does not see
balanced pressures within 30 seconds of going
above the minimum spray pressure, it will detect the
fault and disable the air motor. The default minimum
spray pressure is 2000 psi (14 MPa, 138 bar). Enter

The XP PressureTrak will alarm and shutdown if
it detects either A or B fluid pressures above the
maximum working pressure (see table below). Enter
