ENERGY SETTINGS (ON E MODELS ONLY)
There are 3 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.
AMPLITUDE
The Amplitude Setting is used to make fine adjustments to vibrational
amplitude, from 20% (minimum) to 100% (maximum).
FREQUENCY DISPLAY
The TEST key can also be used to display the running frequency. Press and
hold the TEST key for 3 seconds. The information on the display will change
to include a frequency counter display (Hz). After this switch, the power is
captured (no longer updated) and the frequency display will update every
second. This information can help diagnose problems with the hand gun.
