Error Message:

ALE: Unload Cups timed out moving in

Applies to:

• Trendsetter_400/800_Auto

Operator Action:

Select the RESUME button on the workstation dialog box. If this fails to correct the problem, check that nothing is obstructing the unload cups from retracting. If everything looks normal, then Creo Service should be called.

Service Information:

The unload vacuum cup retract sensors failed to trip within the timeout specified by the aldly ucud parameter. The sensor status may be checked by using the TABLE command. The sensor status should read TRUE if the sensors are activated.

It may be useful to set the 'verbose alcmd' and 'verbose alconv' parameters to 1 in order to obtain further diagnostic information.

Typing "ALE" will display the system air pressure.

Cause:

• The unload vacuum cups may have been obstructed by something.
• The cup retract magnetic sensors may not be adjusted correctly.
• The magnetic sensors may have been damaged.
• The aldly ucud timeout value may be set too short.
• The wiring to the air valve solenoid may be disconnected or damaged.
• The wiring to the magnetic sensors may be disconnected or damaged.
• The pneumatic speed controls may be mis-adjusted.
• The pneumatic system may be damaged.
• The air supply may be low or turned off.
• If the unload vacuum cups move in and out properly but the sensors are not working, then the sensors may be temporarily masked off by setting al ucs to 0. Masking off these sensors will get rid of the error message but will cause the machine to run significantly slower than it used to.
• WARNING: Masking off sensors disables proper error checking!
