Failure in electronic unit.
Stabilized power supply
voltage, powering the
control panel is lower
than the required level.
Short circuit may occur in
the force and position
sensors sockets of RLL

caused
by water entering the
sockets
Disconnect the main control panel from the common
cable. Measure stabilized power supply voltage of the
terminals 6 (minus) and 4 (plus) of the control panel
socket, which shall make 9.5 - 10 V (with the engine
running). If the supply voltage is low or in absence of it,
check the reliability of electronic unit socket connec-
tion. Disconnect the force sensor and the position sen-
sor of RLL one-by one

( Figure 3.18.1 ) .
Break of the sensor wire,
the sensor was not con-
nected or adjusted
1. Faulty adjustment of the position sensor.
Disconnect the cable socket from the sensor. Unscrew
the sensor. Lift the LL in an uppermost position by re-
mote buttons or button “lift” on the solenoid (bottom so-
lenoid). Screw the sensor in by hand as far as it may go
and unscrew by 2 turns. Connect the cable socket to
the sensor. Lower and lift in an uppermost position the
LL by means of the control panel. Lift indicator shall be
out. If the indicator is still flashing, make the position
sensor further by 1/6 of a turn. Check the system op-
eration again. If it is necessary (lift indicator is not out in
an uppermost position), make the position sensor a lit-
tle bit further and try to check again. If the adjustment
was made in a proper manner, LL shall be lowered and
lifted by means of the control panel to the extreme posi-
tions. The lift indicator shall be out in an uppermost po-
sition
. Failure of the position sensor.
2.1 To check the operability of “BOSCH” position sen-
sor, dismount it from the tractor. According to the elec-
tric circuit diagram of the RLL control system (figure
6.12.2, the position sensor connection), it is required to
supply voltage of 10V (in case the power supply unit is
not available, voltage of 12V can be supplied from the
accumulator battery for a short moment) to: output 1
“load” (minus) and to output 3 “+” (plus) and pressing
the sensor migrating rod by a finger, measure the volt-
age at the sensor output by the testing apparatus: be-
tween output 2 – “signal” and output 1 – “minus”. While
the full sensor rod (core) shifting, the voltage at the
sensor output shall be measured within the limits from
0.2 to 0.75 of the value of voltage supplied to the sen-
sor. If the specified parameters are broken, it is re-
quired to mount a new sensor on the tractor and adjust
it properly. Numbers of sensor outputs are indicated on
the cable socket connector which is attached to the
position sensor.
