3 - Working : Phase 1 (no action)
The pressure from the accumulator block arrives on P. The ball stops the oil. Due to the fact that we do not use the brake, L is connected to N. Thus, the LS line is connected to the return tank.
Phase 2 (the driver starts the action)
0 7
When the driver begins to push on the brake pedal, all components are in contact. In this case, the LS line is cut (L). The master cylinder is ready to send the pressure toward the brake with the assistance.
Phase 3 (during the action)
When the driver pushes completely the brake pedal, the piston moves and the ball does not stop the oil. In this case, the pressure is sent to help the driver. In the same time, the master cylinder sends a pilot pressure toward the �ow divider to have the priority on braking. F70-3-0027EN

DANGEROUS MOVEMENTS CUT-OFF OPERATING PRINCIPLES Movement cut-off is activated by the VRP/SPU or VCI at 105% gauge signal. If gauge signal exceeds 112%, the VS also cuts out. (These �gures can change, depending on the jib angle) VS cut-out occurs 7% after proportional cut-out, to cater for the eventuality of the SPU taking longer to carry out a proportional cut-out. The VS will then cut out all movements at 112%.

2 � TROUBLESHOOTING
b
Before carrying out any of the fault-�nding procedures to detect the cause of the breakdown or before removing the distribution unit, it is essential to �rst carry out an examination of the machine’s hydraulic circuit in order to eliminate any breakdown resulting from causes external to the SX 14 S distributor unit.
Faults arising from malfunction of receivers linked to the distribution unit.
Results noted Lack of power at all receivers
Probable causes - LS Limiter defective
Additional checks Solutions Measure pressure (see - Change the LS limiter (cf. § 5.1) unit speci�cations)
- LS limiter out of adjustment
- Adjust
- Secondary suppression limiter out of adjustment - Secondary limiter stuck open (return to tank)
- Reset to design pressure (see unit speci�cations)
Lack of speed in one or all movements
For SX 14 S �tted with “open center” inlet: “Open center” piston stuck in position P towards T

3 � ESSENTIAL RULES GENERAL NOTES CONCERNING CONNECTING UP THE DISTRIBUTION UNIT – When the unit is removed seal all openings immediately to avoid any possible contamination to the hydraulic circuit. – When re-�tting the unit, remove the plastic stoppers from openings and pipes just before making connections. – Do not tighten unions to a torque greater than that shown in the assembly instructions. – Whenever work is done, check the quality of the oil and the level of �ltration. – The use of PTFE, hemp or sealing compound is forbidden. – Pipework and unions must be under no mechanical strain.

4 � REMOVAL AND RE-FITTING OF THE SX 14 S UNIT 4.1 GENERAL GUIDANCE
b
Before removing the SX 14 S distribution unit it is essential to fully clean the unit and its surroundings. (Do not apply the output from a pressure washer directly to the unit). It is essential that the hydraulic circuit is kept clean of all dirt or foreign objects. Use plastic plugs on openings and pipes as soon as they are removed. Wear protective clothing and use correct equipment to avoid any accident, particularly with the �uid. Use the lifting eye-bolts and appropriate maintenance equipment. Place all the machine’s receivers attached to the distribution unit in their rest positions (resting on the ground, at the bottom of their movement etc.) to avoid any accident arising from unplanned movements as a result of disconnecting the hydraulic circuit. With the machine stopped, release all stored pressure by moving the distribution slides.
4.2 REMOVAL OF THE SX 14 S UNIT e HYDRAULIC COMPONENTS REMOVAL
– – – –
Attach a vacuum pump to the tank to limit the escape of oil when unions are unfastened. Insert the plastic plugs immediately after disconnecting the pipes from the unit. Take care to catch any oil spills in an appropriate container. Unscrew the �xing bolts and remove the distribution unit.
4.3 RE-FITTING THE SX 14 S UNIT 0 7 e HYDRAULIC COMPONENTS REMOVAL
– – – – – –
Ensure mating faces are perfectly clean. Check the mating surface of the unit with the machine for �atness (tolerance 0.5 mm). Check the condition of all the seals on the pipework unions. If the unit has been stored for an extended period, clean it. Offer the distribution unit up to the machine and secure it with bolts. Connect the pipework to the unit, in accordance with the connection diagram and the recommended torque settings. – Ensure that �exible hoses have clearance; they must not be twisted or rubbing on anything. – When assembly is complete the machine can be put back into operation: – Turn down the LS pressure limiter before starting up the machine. – Keep one of the distributor lines activated after the hydraulic cylinder connected to it reaches its end stop.
b
On the distribution line in question, the value of the secondary pressure limiter must be greater than that to be set with the LS limiter.
– Adjust the maximum pressure measured in M at the LS pressure limiter. – Retighten the locknut on the adjusting screw to torque: 20 ± 10% Nm.

DIGITAL MANOMETER BOX FUNCTIONS :
•
Manometer functions : the screen can display all the following items: - Temperature upstream to +/- 2°C - Upstream pressure P1 showing minimum and maximum (700 bar class 0.1) - Downstream pressure P2 showing minimum and maximum (700 bar class 0.1) - Differential pressure dP=P1-P
•
Hold Function : the operator is able to freeze the display to take notes at will
•
Unit Function: the operator can change the measurement unit at will (bar, psi, kPa, mCe).
•
Tare Function: enables taring
•
Leakage Test Function: enables pressure variations to be measured over a set time period
•
Recording Function: a max. of 16000 values may be recorded. The sampling period can be con�gured.
•
0 7
Zero Function: zero is carried out on 2 sensors
