ENERGY SETTINGS
There are 4 energy parameters that can be specified. These are accessed by
pressing the Energy key, which allows specification of the following
parameters. The first menu display will show the following:
Energy Setting – sets the amount of energy in joules to be delivered to the
parts being assembled.
Press the Energy key again (and successively after each menu display) to
advance to these next screen displays.
Energy Limit Low – sets the low energy alarm examination point (as a
process control tolerance limit). An energy alarm will be triggered if the actual
weld energy is less than this value. The energy low alarm will show on the
Alarm Screen display and will be indicated by a flashing LED on the Energy
key. By specifying values for this limit and the Energy Limit High, a weld
energy “window” can be created in which a ”good weld” can occur. (If no
alarms are triggered – the weld cycle occurred within the designated energy
limits.)
Energy Limit High – sets the high energy alarm examination point (see Limit
Low above). An energy alarm will be triggered if the actual weld energy is
greater than this value. The energy high alarm will show on the Alarm Screen
display and will be indicated by a flashing LED on the Energy key.
Energy Cal(ibration) Pulse – The system calibrates itself prior to each weld
cycle. The use of the calibration (cal) pulse enables the machine to
automatically monitor the idle losses in the converter/booster/horn assembly
just as the horn begins its descent to the part. The system subtracts the
energy necessary to vibrate the horn in air from the total energy programmed
to weld a part. The cal pulse may be activated during all modes of operation.
Occasionally, it may be necessary to turn the cal pulse off. For example, in
order to place a part into the horn prior to welding (i.e., vacuum horns), the
cal pulse can be turned off as described below.
The display will read either “ENERGY CAL PULSE ON” or “ENERGY CAL
PULSE OFF.” Press either the Up or Down arrow key (which will act as a
toggle) and the cal pulse display will show either “on” or “off.” When the
desired setting is shown, press the Enter key to enter your selection.
