21. Secure tubing (and sensor cables on left side) with 6 off cable ties – ensure tubes are

not pinched / crushed.

22. On left hand cylinder set the two sensors approx. 60mm from each end of the cylinder.

This will be checked / adjusted once machine is powered up.

23. Refit the pantograph springs.

NOTE

Spring damage can occur if users overstretch the springs when fitting them to the

assembly: this may cause fatigue and accelerate premature failure. Do not use pliers

to aid fitment.

TRA Cylinder Tuning:

Reconnect the air to the machine, power up and enter diagnostics. Make fine adjustments to

the two sensor positions. Move the TRA as required to the trigger points.

• Home position.

• Over rails position (not pressured down). Ensure the sensor is positioned to trigger on

at this point and remain on while the TRA is pressured and the rising table translates

to vision height.

The flow control adjustment features are factory set to zero and require further adjustment.

Set the flow controllers using the special tool (212511). The required positions are as follows:

TRA (Left & Right) - Front (Out) = 3.0 turns from closed position.

TRA (Left & Right) - Rear(In) = 1.0 turn from closed position.

TRA (Left & Right) - Rear(Out) = 7.5 turns from closed position.

Apply a small dot of Varnistop Loctite 7400 to confirm setting has been done.

Cycle the TRP a few times to check consistent sensor operation and that Left Hand and

Right cylinders operate together (same speed), if not adjust Sensor position or flow

controllers.

NOTE

Cycle the TRA a few minutes to confirm there are no timing issues relating from speed,

sensor positioning or the function of the cylinders.

Observe the sensor states and confirm they are switching on at the over rails position and

home position.

Objective 10: Locate, remove and replace TRA Stripper Pins

The stripper pins on the TRS assembly are there to aid separation of the TRP plate from the

Active Surround before returning to its home position.

Locate the Stripper Pins on the machine.

Remove and Replace both Stripper Pins:

Preparation

1. In Diagnostics, drive Rising Table to Transport Height.

2. Drive TRP over Rails Position.

3. Remove any previous stripper pin components and fixings.

4. Clean the two striker plates (behind rail cap) to remove any contact debris on both

side of the rail cap.

Replacement:

1. Assemble a half nut and crinkle washer onto each new pin assembly.

2. Insert the threaded part of each pin assembly upwards into the tapped holes of the bar

until the top surfaces are flush.
