Check transducer signals in central unit. Connect pressure transducers to cable.
Disconnect wire No. 4 of transducer cable from X1:21 (signal piston side).
Measure transducer signals (0. . .-1V) between Pin 19 (ground) and wire No. 4 of piston cable.
Disconnect wire No 4 of transducer cable from terminal block X1: Pin 16 (single rod side).
Measure transducer signals (0. . .-1V) between Pin 19 (ground) and wire No. 4 of rod cable.
Refer to system wiring diagram.
Correct?
No
No
Correct?
Yes
Transducer defective-replace transducer and reset pressure channel.
Yes
Connect wire No. 4 from transducer cables back to terminal X1:16 (rod side) and terminal X1:21(piston
side). Without pressure in pipes or hydraulic pipes disconnected from transducer , check 0-point
adjustment on connection board.
Measure between test point MP10 (ground) and test point MP11. Signal should be 0.50V (piston side).
Measure between test point MP10 (ground) and test point MP12. Signal should be 0.50V (rod side).
Refer to system wiring diagram.
Correct?
No
Measure voltage between test point MP10 (ground) and test point MP11
and reset with P1 to 0.50V (piston side).
Measure voltage between test point MP10 (ground) and test point MP12
and reset with P2 to 0.50V (rod side).
If not adjustable, replace transducer.
