PROFILE NUMBER Keys
With the graphics screen on the display, these keys will increment/decrement the
heat profile number on the graphics screen. With the data screen on the display,
pressing either PROFILE NUMBER key returns the graphics screen to the display;
the keys will then increment/decrement the profile number on the screen. The
PROFILE NUMBER up/down keys are disabled when any screen other than the
graphic screen or data screen is on the display.
The number of possible heat profiles than can be stored ranges from 1 to 15.
COUNTERS Key
This key brings up the
REFLOW COUNTERS screen.
This screen provides a menu of selections for
setting the thermode cleaning and thermode
replacement counters, and choosing responses to
the counter settings.
NOTE: With this and all other menu screens
on the display, you will not be able to initiate the
heating cycle.

Total Usage Counter
Press the 1 key to edit the total usage counter. With the numeric keys, you may select a number up to
9999999. The selected number is the total number of reflows completed since the counter was last
edited. When that number is reached, an alarm will be set.
Good Reflow Counter
Press the
2 key to edit the good reflow counter. This option is the same as the total usage counter except
that only good reflows are counted.
Clean Counter
Press the
3 key to edit the clean counter. The count that you enter will raise an alarm to signal the
operator to remove baked-on flux and other residues from the face of the thermode. Particle buildup
slows down heat transfer from the thermode to the parts. Use an initial Clean Thermode value that is
based on real factory operating conditions.
