Power LED
The front panel
POWER
LED
glows after the rear panel
AC power switch/circuit breaker is turned ON:
On start-up, the light flashes GREEN for a few seconds,
and then turns steady GREEN. This indicates AC power
has activated the press.
When the AC power switch is turned to the OFF position,
the front panel
POWER
LED
goes out indicating the press
no longer has power.
NOTE
Go to
Section 5 - Operation, Start-up
Sequence
for an explanation of the
press start-up sequence.
CAUTION
If there is an overload fault
verify that the ultrasonic stack
is not damaged.
System Power Output Level
(Bar Graph)
A bar graph displays the percentage of ultrasonic power
being drawn by the load. See Figure 4-7 to the right.
Peak Detect Feature
To indicate the maximum peak power achieved during a
weld cycle, the segment in the bar graph corresponding
to the peak level remains on (for about one second) after
the weld cycle has been completed.
Bar Graph Power Scaling
Power scaling is related to amplitude. At 100% amplitude
the whole graph is lit, and the press is operating at 100%
power. At 50% amplitude the entire graph is lit, and the
press is operating at 50% power.
If the amplitude setting is lowered, the graph rescales
automatically according to the revised amplitude.
Example:
With a 1200W press, at 50% amplitude, if the
whole graph is lit, that represents 600W.
