Overview
The purpose of the XP PressureTrak is to shut down the
sprayer is 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 15.
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 Window
Below Minimum Spray Pressure
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 Spray Pressure
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 he fault and disable 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 (see
Setup Mode Details
,
page 24).
Maximum Spray Pressure
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
Setup Mode to reduce the maximum allowable pressure
set point (see
Setup Mode Details
, page 24).
