Introduction

Tools Required

PCL airline connection

12mm blanking ports

Valve Manual over ride tool

Standard screwdriver set

Additional colleague when setting regulator pressures for outputs

Parts required

R0015040 completed module

Étape 1 - Safety

Output testing will require valve operation with no e/s circuit

Ensure the following

Work area is clear from all components not required for testing

All colleagues are aware of the procedure being undertaken

No additional colleagues are working on the module

PCL coupling is accessible to release pressure in case of emergency

Testing procedure is fully adhered to

Étape 2 - Set Air service unit soft start

Wind fully out soft start screw situated on top on main air service unit

Étape 3 - Check all open ports

Ensure all open ports and trailing pipes are suitably blanked

Étape 4 - Connect main PCL

Connect main pcl air feed to air service unit

Increase Air service unit pressure to 6.0bar /6mpa

Étape 5 - Check for leaks

Check for audible leaks on the red pipe lines installed and correct if found

Check air gun regulator functions properly . Fully open the regulator (2 bar limited ) and test air gun assembly

Étape 6 - Manual overide

Enable the manual over ride on the main air service unit

This will purge the system with air.

Étape 7 - Check for leaks

Check for audible leaks on blue Pipe line, and active control pipes to cylinders and regulators

Étape 8 - Check home positions

With the system in the natural state when over ridden, the following cylinder positions should be confirmed

Étape 9 - home positions for outputs

Y80 Infeed Top clamp contracted

Y82 Outfeed top clamp contracted

Y91 eject cylinder contracted

Y202 clamp infeed side extended

Y204 Clamp pos contracted

Y206 Centralise contracted

Étape 10 - home positions for outputs

Y207 Saw cut contracted

Y210 Z support infeed contracted

Y213 Saw blowers switched off

Y214 Z turret infeed Not moving

Y215 Z turret outfeed . Not moving

Y224 Z support outfeed contracted

Étape 11 - If any deviation from the above

If any deviation from the above check pipe connections to incorrect output

Étape 12 - Manual valve over ride

Each valve can be manually fired from the over ride button. Pressing this will activate the valve and fire the cylinder /output

when a valve is over ridden, ensure attention is paid to any new air leaks that could become present in the active line when fired

Étape 13 - Y80 Clamp infeed top

Fire and hold valve

Adjust regulator to 2 M.P.A

Cylinder should extend

Should retract when valve released

Étape 14 - Y82 Clamp outfeed top

Fire and hold valve

Cylinder should extend

Should retract when valve released

Étape 15 - Y91 Eject

Fire and hold valve

Eject table should move away from saw head

Should retract when valve released

Étape 16 - Y202 Side clamp

Fire and hold valve

Set regulator to 2 M.P.A

Side clamp should move towards backfence rollers

Should retract when valve released

Étape 17 - Y204 Clamp position

Fire and hold valve

Clamps should move towards from of machine.

If movement is slow/not present check flow restrictors on back of electrical cabinet identified as 2049

Should retract when valve released

Étape 18 - Y206 Centralise

Fire and hold valve

Set regulator to 2 M.P.A

Saw head should move towards rear of machine

Should retract when valve released

Étape 19 - Y207 saw cut

Fire and hold valve

Saw head should raise up

Should retract when valve released

Étape 20 - Y210 Z support infeed

Fire and hold valve

Infeed side z block should fire towards back fence

Should retract when valve released

Étape 21 - Y212 Hi low pressure

assistance required from colleague

Fire and hold Y80 output , infeed top clamp should move down. Keep Y80 held down

Top clamp block pressure should be weak enough to override by hand and move clamp back towards cylinder

Additionally fire Y212, this should switch clamp to high pressure and stop clamp being able to be over ridden by hand

Étape 22 - Y213 Saw blowers

Fire and hold valve

Blowers should switch on

Check operation of inline flow controllers .

When fully closed air flow should stop completely. If air flow can not be completely stopped by flow controller, it is fitted the wrong way around. Change and recheck if this occurs

Étape 23 - Y214 Z turret infeed

Fire and hold valve

Infeed turret should rotate once

Release and fire valve again and turret should again rotate one position

Étape 24 - Y215 Z turret outfeed

Fire and hold valve

Outfeed turret should rotate once

Release and fire valve again and turret should again rotate one position

Étape 25 - Y224 Z support outfeed

Fire and hold valve

Outfeed side z block should fire towards back fence

Should retract when valve released

Étape 26 - output testing complete

Disconnect pcl air supply

Remove temporary blanks fitted
