TIME SETTINGS
There are 3 time parameters, or timers, that can be set. They are accessed
by pressing the Time key which allows specification of the following time
parameters. The first menu display will show the following:
Weld Time – sets the duration of time for which ultrasonic vibrations are
applied to the parts.
If the time value is cleared (zero or dashes displayed on screen), then
ultrasonics will be activated when the hand gun trigger switch is depressed.
Press the Time key again (and successively after each menu display) to
advance to these next screen displays:
Time Limit Low – sets the low time alarm examination point (as a tolerance
limit). A time alarm will be triggered if the actual weld time is less than this
value. The time low alarm will show on the Alarm Screen display and will be
indicated by a flashing LED on the Time key. By specifying values for this
limit and the Time Limit High, a weld time “window” is created that defines a
”good weld.” (If no alarms are triggered – the weld cycle occurred within the
designated time limits.)
Time Limit High – sets the high time alarm examination point. A time alarm
will be triggered if the actual weld time is greater than this value. The time
high alarm will show on the Alarm Screen display and will be indicated by a
flashing LED on the Time key.
