3 The Function of LUCAS

3.1 PNEUMATICS

LUCAS is supplied with Compressed Air according to Instructions for use LUCAS.

In order to produce a compression force that is independent of pressure supplied, LUCAS contains a High Flow Valve (HFV) that regulates the pressure to approximately 2.8 bar.

The regulated pressure goes to the Mode Switch which have the function of a 3/3 valve (three inlets/outlets and three different states). When the Switch is in Adjust mode, no pressure is present at any of the outlets.

When the Switch is turned into Lock position, the pressure will go through one of the outlets of the Mode Switch to the Height Adjustment Lock and its cylinder, affecting the Piston to lock the Height Adjustment.

Turning the Switch into Active position will let the pressure through both outlets, affecting the Height Adjustment Lock, but also letting pressure into the regulator of the Timing Module.

In the Timing Module the pressure is regulated to 2.5 bar. The output from the Timing Module will supply 2.5 bar to the Main Valve in square formed pulses.

The Main Valve has a piston that will control the flow to the Main Cylinder with pressure from the HFV, either to the Compression Cylinder to move the Piston down, or to the Decompression Cylinder to move the Piston up.

4.2 EXPLANATION TO THE TROUBLESHOOTING FLOW CHART

This section is an explanation to the Troubleshooting Flow Chart 4.2.1 MODE SWITCH

The Mode Switch is supplied with approximately 2.8 Bar on the inlet (1) from the High Flow Valve (HFV).

With the Mode Switch in position “Adjust” there should be no pressure at any of the outlets (2 and 3)

With the Mode Switch in position “Locked” there should be 2.8 Bar on outlet 2 that supplies the Locking Mechanism.

With the Mode Switch in position “Active” there should be 2.8 Bar on both outlet 2 and 3, supplying both the Locking Mechanism and the Timing Module.

Table 1 Pressure outputs on Mode switch. 4.2.2 TIMING MODULE

The Timing Module is supplied with 2.8 Bar from the Mode Switch.

The Timing Regulator regulates the pressure to 2.5 Bar.

The outlet from the Timing Module should be a square formed pulse, 0 – 2.5 Bar with a frequency of about 100 pulses/minute.

The Timing Module can be adjusted according to 7.5


11

4.2.3 MAIN VALVE

The Main Valve is supplied with a square formed pulse 0 – 2.5 Bar from the Timing Module.

The piston in Main Valve should move back and forth, forcing the main pressure (2.8 Bar) to alternate between the Compression Cylinder and the Decompression Cylinder.

4.2.4 HFV

The HFV (High Flow Valve) regulates the input pressure to about 2.8 Bar.

If the maximum force is too low, too high or if Td (Time down) is too long an adjustment of HFV can be done according to 7.6.

Before adjusting HFV make sure that the Main Cylinder works ok and is lubricated properly, if the resistance is too high in the Cylinder this has to be dealt with first.

An increased friction inside the HFV may cause a too long Td (Time down), if this is the case a replacement has to be done.

7.5 TIMING MODULE ADJUSTMENT

There are two versions of the Timing Module: 100409-00 here called Version 1, and the new improved Timing Module 100655-00 here called Version 2.

When the Frequency and/or Ratio is out of limit an adjustment has to be made, this is done by turning the two adjustment screws at the Timing Module. NB! The surrounding temperature should be 15-35 ºC (60-95 ºF).

7.5.1 ADJUSTING TIMING MODULE (VERSION 1)

Timing Module Regulator (2.4-2.6 Bar)

Upper Adjustment Screw

Lower Adjustment Screw

Use a flat screwdriver 0.5x2.5 mm for the Lower Adjustment Screw and a 7 mm wrench to loosen the counter nut for the Upper Adjustment Screw. The upper screw can then be adjusted by hand. Run LUCAS at LISA while performing the adjustments.


44

Tip! Set the markers in SoftLISA to the desirable values, then adjust the screws while running LUCAS until you reach the preset markers.

When the right value is achieved lock the adjustment screws with BLR Bloc’Lube (as picture).

Perform a Functional check according to 7.2.

7.5.2 ADJUSTING TIMING MODULE (VERSION 2)

Timing Module Regulator (2.4-2.6 Bar)

Adjustment Screw Compression Time

Adjustment Screw Decompression Time

Use a 7 mm wrench to loosen the counter nut for the Adjustment Screws. The screws can then be adjusted by hand.

Run LUCAS at LISA while performing the adjustments.

The left Adjustment screw affects the Compression time and the right screw affects the Decompression time.

Tip! Set the markers in SoftLISA to the desirable values, then adjust the screws while running LUCAS until you reach the preset markers.

When the right value is achieved tighten the lock nuts and apply BLR Bloc’Lube (as picture).



45

7.6 HIGH FLOW VALVE (HFV) ADJUSTMENT

When the Maximum Force is too high or too low an adjustment of the HFV has to be made, this is done by turning the adjustment screw on the side of the HFV.

Adjustment Screw

Turn the screw clockwise to increase the force and counter-clockwise to decrease the force. HFV Adjustment Tool (100417-00)

Run a Maximum Force Test according to 7.4 at LISA while performing the adjustments.

Tip! Set the marker in SoftLISA to the desirable value, then adjust the screw while running LUCAS until you reach the preset marker.

When the right value is achieved lock the Adjustment Screw by applying BLR Bloc’Lube (as picture).

Perform a Maximum Force Test according to 7.4


If the force is not correctly set, compression force and displacement may be reduced causing poor circulation for the patient.
