The LCS load control system provides protection against tipping forward by progressively reducing boom lowering and tilt functions as stability limits are approached. It has two modes - Load Control mode, which is automatic, and Ground Work mode, which functions like a standard LMI. In Load Control mode, boom lowering and tilt are derated, while extend functions normally until the limit. Once reached, lowering, tilting, crowding and dumping are prevented to avoid further instability. Boom lift and retract allow load retrieval. The system uses LED indicators and switches to monitor stability and select modes.

About the Load Control Systems
General Information
A Load Control System (LCS) is an enhancement to the
devices that JCB currently fit as standard, i.e. loadcharts,
boom extension markers and Load Moment Indicator
(LMI). These are still the primary source of information to
allow the operator to operate the machine correctly. The
Load Control System offers additional control if the
operator makes an inadvertent movement of the load. The
system must not be relied upon as the primary source of
protection for the machine. The duty of care is still with the
operator/site agent to:
– know the mass and load centre of loads being
handled.
– know boom angle and extension that will be required
to place the load (this can be checked by doing a dry
run first without the load)
– whilst moving the load, obey LMI indications, lift
charts and boom extension markers.
Note: Note: The LCS provides a degree of protection only
against the machine tipping forward. It does not protect
against tipping sideways or rearwards, nor tipping due to
the machine being used on unsuitable ground nor operator
mishandling (sharp direction changes, etc.).
Neither will the system protect against instability due to the
stabiliser legs being lifted nor misuse of the chassis
levelling (sway) function (if either of these options are
fitted).

Identification
There are many variants of the Load Control System.
Although they all have a common purpose - to help prevent
the load moving into a position which would make the
machine unstable - there are variations in the way this is
achieved on different Loadall models. Also, some variants
of the system incorporate additional features such as
stabiliser isolation and load retrieval. The following table
will help you identify which variant may be installed on any
particular model of Loadall.
Note: For 536-60, 536-70, 531-70, 535-95 and 541-70
machines, you will need also to refer to the table of
Hydraulic System Variants. K Table 2. Identification of

Hydraulic System Variants (536-60, 536-70, 535-95, 531-70 & 541-70)
The hydraulic circuit of the 536-60, 536-70, 535-95, 531-70
and 541-70 machines may be one of a number of variants.
Each variant requires a slightly different Load Control
System. If you are working with one of these machines it is
important that you know which type of hydraulic system is
installed, to ensure that you refer to the correct hydraulic
and electrical diagrams in this supplement. The following
table shows the easily identifiable differences between

LCS (Six Valve Manifold)
Introduction
Machine Model and Serial Number
The LCS Load Control System (LCS) is compatible with
following models in the JCB Loadall machine range:
– 528-70 Up to SN 797511
– 532-120 Up to SN 1064455
– 533-105 Up to SN 1064702
– 535-95 Up to SN 1064715
– 537-135 Up to SN1064473
General Description
When the LCS is selected, it reduces the risk of tipping
forward when the machine reaches a predetermined point
near to its maximum working limit.
This is achieved by stopping boom lower, boom extend,
dump and crowd functions, in order to prevent further
movement of a load past the predetermined point.
Boom lift and boom retract functions are allowed in order
to retrieve the load from a point of cutout.
The system has two working modes, Load Control Mode
and Ground Work Mode. Load Control Mode is
automatically entered when the machine is started.
Note: The LCS provides a degree of protection only
against the machine tipping forward. It does not protect
against tipping sideways or rearwards, nor tipping due to
the machine being used on unsuitable ground nor operator
mishandling (sharp direction changes, etc.).
Neither will the system protect against instability due to the
stabiliser legs being lifted nor misuse of the chassis
levelling (sway) function (if either of these options are
fitted). The stabilisers and/or chassis levelling rams are not
interlocked into the LCS.
In Load Control mode, the boom lower hydraulic supply is
progressively reduced (derated) as the weight on the rear
axle becomes less, ensuring that the load movement is
stopped smoothly and without jerking. The tilt hydraulic
flow is also restricted; this restriction is constant
throughout the range. The extend function operates as
normal until the limit is reached.
It is, therefore, a characteristic of the system that lowering
and tilt movements are slightly slower than when Ground
Work mode is selected. This is normal and does not
indicate a machine fault.
Once the limit is reached, any movement of the load which
would further reduce the stability of the machine is
prevented. This means that extend, lower, crowd and
dump functions are all disabled.
In Ground Work mode, the system functions as the
standard LMI.
Testing procedures described in this manual should be
carried out on level ground with the road wheels in the
straight ahead position.

Introduction
Fig 2. Typical Circuit
The following description, outlines the operation of the
LCS as fitted to Series I machines fitted with stabilisers
(532-120, 533-105 and 537-135). It should be read with
reference to the following:
K Hydraulics Schematic ( T 20)
K Electrical Schematic ( T 22)

In non-stabilised machines (528-70, 535-95), valve C (lift
circuit control valve) is not fitted and references to valve C
should be ignored. The lift service operates normally.
Interface with Standard Hydraulic System
Load Control functions are controlled by the six valve
manifold AA, which is inserted in the hydraulic circuit
between the main control valve block and the service
rams.

Start up
Note: In the following description, the various thresholds
have the meanings below:
The amber light (LED) will be on between minimum and
maximum thresholds.
1 When the machine is started, the system always
enters Load Control (LC) mode by default. If the
stabilisers (if fitted) are down or if the boom is
elevated less than 45°, the system continues to Mode
Selection.
2 If the stabilisers (if fitted) are up and the boom is
elevated more than 45°, the system operation
continues as described below.
Solenoids B, C, E and F have 0 Volts applied.
Therefore, valves B, C, E and F are de-energised.
a Valve B allows pilot oil to flow to tank, causing
counterbalance valve 12 to remain closed. This
means that flow to the lower service is via flow
regulator 7 and proportional valve A. Flow
regulator 7 applies a preset (26 litres/min
maximum) restriction on the oil flow, proportional
valve 4 applies a variable degree of restriction
which depends on the LMI transducer signal.
K Proportional Valve ( T 17), for the operation
of the proportional valve.
b Valves E and F block the direct flow to the tilt
services and allow flow to dump or crowd only
through restrictors 13. Valve C directs lift service
oil from the main valve block (MVB) back to tank,
preventing further lifting.
3 If the signal from the LMI transducer is below the
maximum threshold (green or amber light on), 12
Volts energises solenoid D. Valve D blocks the return
of extend service oil to tank. Valve A is open, to a
degree determined by the LMI transducer signal.
Under these conditions, boom extension and
retraction is permitted and the boom may be lowered
(at a much reduced speed) to a position below 45°.
The system then continues to Mode Selection.
Note: Maximum and minimum threshold values are preset
during manufacture and cannot be changed.
4 If the signal from the LMI transducer is above the
maximum threshold (red light on) (see item 2),
solenoid D is de-energised. Valve D returns the
extend and tilt service oil to tank, preventing tilt or
boom extension. Proportional valve A is fully closed.
Boom extension and lowering is not permitted and the
boom may only be retracted in order to reduce load
moment.
5 If retraction of the boom is sufficient to bring the load
moment below the maximum threshold, operation
continues as in paragraph 2. If the boom cannot be
retracted further and the load moment is still above
the maximum threshold, it will be necessary to use
Override Mode, to lower the boom below 45°. The
system continues to Mode Selection.
Mode Selection
1 If the machine is in LC mode and it is intended to
continue in that mode, no change of mode is required
and the system will carry on in LC mode. K Load
Control Mode ( T 16).
2 If a change of mode is required, the system is put into
a mode change loop by the operator pressing and
holding the mode change button for five seconds to
initiate the change.
If the signal from the LMI transducer is above the
minimum threshold (amber or red lights on), the mode
change is prevented and the system remains in the
current mode. The load moment must be reduced
below minimum threshold (green lights on) by
retracting, lifting or reducing the load and the mode
change button pressed again to initiate mode change.
Note: Before changing mode, the boom should be
retracted and lowered and any load removed. It is not good
practice (although the system does not prohibit it) to initiate
mode changes whilst the boom is raised or extended or if
the machine is carrying a load.
3 Change mode:
a From LC to Ground Work (GW) mode: If the signal
from the LMI transducer is below the minimum
threshold, the change is permitted. The LMI LEDs
flash indicating that the mode change has taken
place, until the mode change button is released,

b From GW to LC mode: If the signal from the LMI

until the mode change button is released, when
the LC symbol is lit. K Load Control

20. LCS (Six Valve Manifold)
Circuit Description
16 169803/3665-3
Ground Work Mode
1 Solenoid A has 0 Volts applied, solenoids B, C, D, E
and F all have 12 Volts applied. Therefore, the
proportional valve is completely closed and all other
valves are energised.
2 Valve B, in the energised position, blocks the path for
pilot pressure to tank. Pilot pressure operates
counterbalance valve 12, allowing lift service oil to
flow to the lift ram. At the same time, valve C
energises, blocking the return path to tank. These
conditions allow boom lift to operate normally.
3 Valves E and F bypass restrictors 13 in the tilt circuit,
and valve D blocks the return path to tank for the tilt
and extend oil. This allows tilt, dump and crowd
services to operate normally.
4 In GW mode, all services operate normally at normal
machine speed. The machine will continue to operate
in GW mode until a mode change to LC mode is
required. K Mode Selection ( T 14).
Load Control Mode
1 If the stabilisers are down, valve C is energised. If the
stabilisers are up, and the boom is below 45°, again
valve C is energised. In either of these conditions,
valve C blocks the return to tank for the lift oil, allowing
the lift service to operate normally.
2 If the stabilisers are up, and the boom is above 45°,
solenoid C has 0 Volts applied, and valve C is de-
energised. In this case, valve C directs lift service oil
from the main valve block (MVB) back to tank,
preventing further lifting.
3 Solenoids B, E and F have 0 Volts applied. Therefore,
valves B, E and F are de-energised.
a Valve B allows pilot oil to flow to tank, causing
counterbalance valve 12 to remain closed. This
means that flow to the lower service is via flow
regulator 7 (26 litres/min maximum) and
proportional valve A. For the operation of the
proportional valve. K Proportional
Valve ( T 17).
b Valves E and F block the direct flow to the tilt
services and allow dump or crowd only through
restrictors 13, slowing the operating speed.
4 If the signal from the LMI transducer is below the
minimum threshold (green lights on), valve D is
energised. Valve D blocks the return of extend and
tilt service oil to tank. Proportional valve A is fully
open. Under these conditions, the machine operates
as normal, with the lower service flow, restricted by
restrictor 7 and proportional valve A (even when fully
open, valve A imposes a certain degree of restriction
on the flow).
5 If the signal from the LMI transducer is between the
minimum and maximum thresholds, valve D is again
energised. Proportional valve A is partially open, to
a degree dependant on the LMI signal. Under these
conditions, all services are operative, with tilt
operating at a speed limited by restrictors 13 and
boom lower speed regulated by proportional valve A
in accordance with the load moment, as represented
by the LMI signal.
6 The conditions described in paragraphs 4 and 5
represent the normal working conditions in LC mode.
The system will continue to cycle around this loop
until conditions change, i.e. the load moment goes
above the maximum threshold, the ignition is
switched off or a change to GW mode is required.
7 If the signal from the LMI transducer is above the
maximum threshold, valve D is de-energised.
Proportional valve A is fully closed. Under these
conditions, tilt, lower and extend services are all
disabled.
8 As the machine is operating at the maximum allowed
load moment, the LEDs flash and the audible alarm
sounds to warn the operator.
9 All functions except lift and retract being disabled, the
operator must lift or retract in order to reduce the load
moment to a level below the maximum threshold.
Otherwise, the system will remain in the conditions
described above.
10 If lift or retracting the boom brings the load moment
below the maximum threshold, the system recycles
through the load control loop continuously until the
ignition is switched off or a mode change is required.
11 It is possible that the machine may be in a position
such that, even with the boom fully retracted, the load
moment may be above the preset maximum
threshold. In this case, it is necessary to use Override
Mode. K Override Mode ( T 17)

Override Mode
1 To enter Override mode, press and hold the test
button. Press the mode change button and hold both
buttons pressed. After ten seconds, visual
confirmation of the mode change is given by the
display LEDs and both mode symbols flashing.
Note: Override can only be entered from LC mode. Whilst
in Override, both mode buttons must be held pressed
continuously. Releasing either or both buttons results in
the system changing back to LC mode.
2 Solenoids A, C and D have 12 Volts applied.
Solenoids B, E and F have 0 Volts applied. Therefore,
proportional valve A and valves C and D are
energised and valves B, E and F are de-energised.
a Valve B causes the lower service oil to flow via
restrictor 7 and proportional valve A. Because the
load moment is at or above the maximum
threshold, the proportional valve allows only the
minimum flow of oil to the lower service.
K Proportional Valve ( T 17).
b Valves C and D allow operation of the lift service
and the tilt and extend services respectively.
c Valves E and F allow dump or crowd only through
restrictors 13, slowing the operating speed.
!MWARNING
Work to the load chart and boom indicators, the load
moment is at maximum level.
5-2-4-16
3 Careful use of the controls may be used to lower and
recover the load. The mode change and test buttons
may now be released and the system will revert to LC
mode.
Note: Valves B, C and D are fitted with a manual override
to enable operation of the machine in the event of solenoid
failure. This facility must be used only by suitably trained
and qualified personnel.
Proportional Valve
Note: The figures mentioned below are for purposes of
explanation only and are not to be taken as accurate for
servicing purposes.
The proportional valve regulates the flow of oil to the lower
service when in circuit. Unlike the other valves, which are
energised by a constant 12 Volts d.c., the proportional
valve is controlled by a method known as pulse width
modulation (PWM).
The energising supply is switched on and off at 100Hz, and
the LC system varies the ratio of the time `on' compared
with the time `off'.
This produces a square wave of 100Hz, with a variable
mark to space (M/S) ratio.
Fig 4.
The average current Z through the solenoid, and hence the
average time the valve is open varies with the M/S ratio,
thus regulating the flow rate of the oil to the lower service.
Below the minimum threshold, the M/S ratio is constant at
60%, allowing the unregulated flow through the valve.
(Note that this is restricted by restrictor 7 to a maximum of
26 litres/min).
As the load moment increases to the minimum threshold
(red light on), the M/S ratio drops to 45%, reducing the flow
to the ram.
22. LCS (Six Valve Manifold)
Circuit Description
18 189803/3665-3
Between the minimum TMIN and maximum TMAX thresholds
(amber light on), the M/S ratio, and hence the flow to the
ram F, varies in accordance with the load moment LM (as
sensed by the LMI transducer) between the values of 45%
at the minimum threshold (green lights on) and 15% at the
maximum threshold (red light on). As a result, the rate at
which the boom can be lowered is regulated in proportion
to the load moment.
Fig 5.
When the maximum threshold is reached, the energising
supply is cut off completely, so closing the proportional
valve and preventing further lowering of the boom.
The exception to this is in Override mode only, where the
energising supply is not cut off and lowering at the
minimum rate is still permitted.

As the Load Control System (LCS) may be fitted to
several types of Loadall machine, those parts of the
schematic which show non-LCS parts of the overall
hydraulic schematic are to be taken as being
representative only.
The schematics shown here, within the bold outline
AA, show how the LCS is integrated into a typical JCB
Loadall.
For details of the standard hydraulic system of a
particular machine, reference should be made to that
machine's Service Manual.
Note: Machines without stabiliser legs (528-70,
535-95) do not have solenoid valve C fitted and port
L3 is plugged.
