Pre-trigger Overtravel
Alarm
Press travel exceeded fixed distance limit while ultrasound was active.
For servo press the distance from pre-trigger to position of trigger is required to be less than 0.25 inches or 6.35 mil
-
limeters. For pneumatic press the distance from pre-trigger to posi
-
tion of trigger is required to be less than 0.75 inches or 19.05 millimeters.
U41

Part Detected
Too Early
Contact between the horn and part was detected before reaching the Sensing Start Position.
Adjust Sensing Start Position to be above contact with part.
Account for variation of heights of unassembled parts. NOTE: Repeated occurrences of this alarm may result in costly damage to servo actuator
.
U413
