9. reen band in the overtravel graph represents values between the top and bottom specification limits set in Setup If an overtravel measurement falls outside of these limits an alarm will be given at the top of the display The possible overtravel alarms are Over Spec Under Spec or Double Dome Once activated these alarms stay on for 20 strokes or until the bodymaker restarts after a stop The Double Dome alarm is given if the change in overtravel from the previous stroke is more than the value of Double Dome Sensitivity given in Setup There is also a No Overtravel alarm which is given when no overtravel is detected This alarm therefore always comes on when the bodymaker is not running but also when it is running but there is no overtravel The Sensor Posn alarm is explained in the Sensor Adjustment section If this alarm is shown the gauge may not measure correctly and the sensor position should be re adjusted If a measurement is incorrectly made this may happen when adjusting the sensor or if you just want to clear the data from the graph to start from fresh measurements can be deleted by selecting the Delete button DELTA H TECHNOLOGY 9 8 Signature The signature of the last measured overtravel can be viewed by selecting Signature This shows the overtravel movement for the last stroke before and after the point at which maximum overtravel was obtained Where it was possible to measure bodymaker speed the x axis will b
