Error code
Description, anticipated
problem
Failure inspection method
23
Failure of the control
panel. Potentiometer of
the depth control lever 4
is
damaged (Figure
2.14.1)
Check the reliability of the control panel sockets and
electronic unit connection, and check the cable for
mechanical damage. Check the voltage output ac-
cording to the electrical connections diagram (Figure
7.2.3)
24
Failure of the control
panel. The RLL upper-
most end position lever 3
is
damaged (Figure
2.14.1)
Check the reliability of the control panel sockets and
electronic unit connection, and check the cable for
mechanical damage. Check the voltage output ac-
cording to the electrical connections diagram (Figure
7.12.3)
28
Failure of the control
panel. The RLL operation
lever 7 (Figure 2.14.1) is
damaged Check the reliability of the control panel sockets and
electronic unit connection, and check the cable for
mechanical damage. Check the voltage output ac-
cording to the electrical connections diagram (Figure
7.2.3)
31
Failure of the right force
sensor 10
(
Figure
3.19.1
)
. Cable breaking
or the sensor short circuit
32
Failure of the left force
sensor 11
(
Figure
3.19.1
)
. Cable breaking
or the sensor short circuit
To check if it is failure of the sensor or the cable (in
circuit to the sensor), disconnect the sockets from the
cable to the sensors (left and right) and interchange
their positions (the socket from the left sensor to the
right sensor channel and the socket from the right
sensor to the left sensor channel). If after that the er-
ror code has changed (31 was replaced by 32 or 32
was replaced by 31), that means that the sensor is
out of order, if the error code is still the same, that
means that the cable is out of order
Easy defects
34
Failure of the control
panel. Potentiometer of
the RLL speed control
lever 1 (Figure 2.14.1) is
damaged Check the reliability of the control panel sockets and
electronic unit connection, and check the cable for
mechanical damage. Check the voltage output ac-
cording to the electrical connections diagram (Figure
7.2.3)
36
Failure of the control
panel. Potentiometer of
the control method
choice lever 2 (Figure
2.14.1) is damaged Check the reliability of the control panel sockets and
electronic unit connection, and check the cable for
mechanical damage. Check the voltage output ac-
cording to the electrical connections diagram (Figure
7.2.3)
Code is
not dis-
played
spontaneous lift of RLL
after the engine start “Lift” forward/reverse spool was blocked abroach.
Disconnect the cable sockets from the “Lifting” and
“Lowering” solenoids. If the failure is still displayed,
eliminate the failure in the RLL hydraulic system.
