Error Message:

ALE: plate picker vacuum did not release in time, check air lines

Applies to:

• Platesetter_3244

Service Information:

Check if plate was really released. Check for oil in air lines and any other possible cause for air valve to be sticking. Perform Cal pvac (& cal uvac). NOTE: Vacuum thresholds are very sensitive to ambient temperature. Replace PPE board (or U15 ACD0838) if problem persists. aldly release may be increased to 1.5 seconds but this will directly affect the load/unload time.

Operator Action:

Resume. Inform Creo response center so that the problem can be checked at next p.m. inspection. If problem persists, call Creo service.

Cause:

• During a load, the plate is released from the picker and allowed to settle onto the registration pins. After a timeout (release_delay), the vacuum value is checked just to make sure that it is at least below the grip threshold (pvt), (or release threshold for fw 2.26) if not then this error is reported, unsolicited.
