column of Table 3-13
. All shaded boxes to the
right of the number indicate senders that failed
calibration. Troubleshoot the corresponding
system to determine the cause of the fault
NOTE: The cause of a failed calibration or faulty display
pressure reading in the cab may not be the
pressure sender. The cause of the fault could be
trapped air or hydraulic pressure in the system.
Before replacing a pressure sender, do the
following:
• Perform pressure sender calibration steps.
• Attach an accurate hydraulic pressure gauge
to the quick-coupler at the suspect pressure
transducer (see Section 2 of Service Manual).
• If pressure appears on the gauge, bleed the
corresponding system so the gauge reads
zero pressure.
• Repeat calibration steps and check pressure
on the display in the cab with the engine
running at idle — the display reading and the
gauge reading should be the same.
• Before replacing a pressure sender, check the
signal voltage at the sender. It should be 1.0
volt against ground at 0 psi.
3. Proceed to next procedure, or exit calibration screen by
pressing bottom of CRANE MODE switch. Cursor (*) will
disappear from screen.
