when a 3000psi one is needed).
Check CALIBRATIONS / HEIGHT CALS; the “Height” indicates the first height at which there
was insufficient difference and the “Up” and “Down” values show the loaded pressure (first) and
the difference between loaded and empty pressure (second).
F42:LOW PRESSURE
This message indicates that the pressure is too low (0.5V or less) when the elevation switch
opens during the DYNAMIC lift.
This message would occur if the pressure sensor was disconnected, or if there were some other
wiring error.
Check DIAGNOSTICS / SENSORS to check the pressure.
F43:HIGH PRESSURE
This message indicates that the pressure is too high (4.5V or more) when the elevation switch
opens during the DYNAMIC lift.
This message would occur if the wrong pressure sensor was fitted, or if there were some other
wiring error.
Check DIAGNOSTICS / SENSORS to check the pressure.
F44:LOW PRESSURE
This message indicates that the pressure is too low (0.5V or less) at a STATIC measurement
point.
This message would occur if the pressure sensor was disconnected, or if there were some other
wiring error.
Check DIAGNOSTICS / SENSORS to check the pressure.
F45:HIGH PRESSURE
This message indicates that the pressure is too high (4.5V or more) at a STATIC measurement
point.
This message would occur if the wrong pressure sensor was fitted, or if there were some other
wiring error.
Check DIAGNOSTICS / SENSORS to check the pressure.
F46:CHECK ELEV
This message indicates that the elevation switch opened more than once during the DYNAMIC
lift.
F47:CHECK ELEV
This message indicates that the elevation switch closed more than once during the DYNAMIC
lower.
F48:BAD PRESSURE
This message is given if the pressure sensor output is out of range at the start of calibration.
The sensor output must be between 0.5V and 4.5V.
Check DIAGNOSTICS / SENSORS to see the output. A reading of 0V or 5V is probably due to a
wiring problem.
F49:TOO FEW
The minimum number of static calibration points was not achieved.
