Auteur avatarGareth Green | Dernière modification 2/04/2024 par Gareth Green en cours de rédaction

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


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

1 Y80 Infeed Top clamp contracted

2 Y82 Outfeed top clamp contracted

3 Y91 eject cylinder contracted

4 Y202 clamp infeed side extended

5 Y204 Clamp pos contracted

6 Y206 Centralise contracted

Étape 10 - home positions for outputs

1 Y207 Saw cut contracted

2 Y210 Z support infeed contracted

3 Y213 Saw blowers switched off

4 Y214 Z turret infeed Not moving

5 Y215 Z turret outfeed . Not moving

6 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 0.2 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 0.2 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
