No Fault in cable
If transducer's) are not adjustable.
Replace pressure transducer's) and adjust zero point.
Refer to system wiring diagram and pressure transducer zero
point adjustment Procedure..

Measure signal from pressure transducers in central unit. The return signal is a current output and must
be measured in series. Set Voltmeter to measure amps.
Piston Side
, remove Wire #2 from X1:32 in the central unit and connect one ammeter lead to wire #2
and the other lead to X1:32. The measurement should be between 4-20ma (4ma when there is no
pressure in the hydraulic lines; 0 psi).
Rod Side
, remove Wire #2 from X1:33 in the central unit and connect one voltmeter lead to wire #2
and the other lead to X1:33. The measurement should be between 4-20ma
(4ma when there is no pressure in the hydraulic lines; 0 psi).
Refer to system wiring diagram.
Check continuity of wire 2 and pin B in pressure transducer cable by first
unplugging the transducer cable from transducer and second moving wire 2 to
the ground terminal X1:36. Measure voltage at the cable connection between A
(+UBV) and B (ground) for each connector.
Re-connect the wiring a shown on the system wiring diagram.
NO
Adjust zero point on pressure transducers.
