.31
Center section pressure 1 low
(center or center left sensor)
• Check center section valve for proper
operation. Valve may have failed to open
when commanded on.
• Check center section strainer for blockage.
Clean if necessary.
• Check if center section transducer 1 is reading
correctly in pressure sensor readings.
.4
Center section pressure 1
sensor not detected (center or
center left sensor)
• Check the pressure transducer connection
and cabling for damage. If necessary, replace
the cable or pressure sensor.
523236
.31
Center section pressure 2 low
(center right sensor)
• Check center section valve for proper
operation. Valve may have failed to open
when commanded on.
• Check if center section transducer 2 is reading
correctly in pressure sensor readings.
.4
Center section pressure 2
sensor not detected (center
right sensor)
• Check the pressure transducer connection
and cabling for damage. If necessary, replace
the cable or pressure sensor.
523232 .18 Minimum pressure
• Check if tank is empty.
• Check if strainer is blocked. Clean if necessary.
• Check for system leak. Repair as needed.
• Check target pressure and rate. Increase if
necessary.
• Increase travel speed.
• Check if tank sump is closed. Open if not.
• Check if master valve is closed. Open if not.
• Check Minimum Pressure setting. Decrease if
necessary. Value should be >6psi.
• Check if boom transducer is functioning
correctly in pressure sensor readings.
• Check the boom pressure transducer
connection and cabling. If necessary, replace
cable or pressure sensor.
• Check wiring to pump pwm valve. Make sure
connections are secure.
• Go to manual mode and increase DC to see if
pump is working and pressure builds with
increasing control effort.
• Check PWM MAX value is >30.
• Check PWM control range using PWM Health
Test. Overall range should be >20%.
