OPERATING PROCEDURES
D. TYPE “2” OPERATION
Before proceeding with this type of operation, attach the first external
temperature probe (Marked “B”) to the underside of the PCB to be worked
on. The second probe can be placed near areas of interest. Such as near
the component to be worked on.
This type of operation utilizes the first external temperature sensor to
control the heat. Type “2” operation uses the profile to slowly control the
rise and fall of the temperature at board level. While the second external
temperature probe can be attached for additional monitoring.
1. To enter type “2” mode. Select 2 at the initial screen then press the
select button. The display would change to “run Prof”. This signifies
we are now in the type “2” mode.
2. To adjust the time and temperature profile of each segment press the
selection button. The top display will show which segment “SEG1” we
are currently adjusting while the bottom display shows whether we are
adjusting the time (suffix “t”) or temperature (suffix “C”).
3. Press the increase or decrease button to adjust the desired time and
temperature. The set temperature is adjustable from 50 to 250 C and
time 5 to 200 seconds.
4. To start preheating with the profile, repeatedly press the selection
button until the display shows the word “Run Prof” then press the
increase button. A 3 second countdown will commence before
automated reworking starts.
5. To see the running time, or current segment the system is processing
or the temperature of the external temperature probes. repeatedly
press the selection button to switch between different views. Follow
the suffix guide to determine displayed temperature.
6. After the process is finish the display will show “End”, press the
increase button to save the profile and exit to profile adjustment
mode.
7. To exit before the process is finished press the increase button while
the profile is running. The system would exit and return to profile
