Description of the flow chart
By pressing the (+) and (-) keys, the user
moves from the actual value display to the
program display. By pressing the same keys
one more time, the requested program
(Pr1 to Pr5) can be selected. The user can
return to the actual value display by press-
ing the ENTER key. The parameters of the
selected program are immediately loaded
and active. If the ENTER key is not pressed,
the station automatically jumps back to the
actual value display after 8 seconds.
In this case, too, the parameters of the selected program are loaded and take effect im
-
mediately.
5.2
The menu system
The operating concept of the control station provides easy
access to all setting options by means of only three control
buttons. All programs are set in the same way. Once the
parameters have been entered for a given program, the
station can be quickly converted for different, frequently
recurring soldering operations by simply changing the program. Elaborate changes of the
individual parameters are not necessary.
For setting a program, the latter must first be
preset as described in section 5.1. All of the
following setpoint and parameter changes now
refer to this program. The menu is operated via
the three keys +, - and ENTER. Settings are
automatically saved and take effect immediately.
After 8 seconds, the station switches automati
-
cally to the actual value display (temperature
display) (Figure 2). This view always shows the
current soldering temperature (three digits) and (as the 4th character) the unit of tem-
perature: C (Celsius) or F (Fahrenheit).
To assist your navigation within the menu struc
-
ture, a symbol corresponding to the menu item always flashes in the fourth position of the
display.
