OPERATING PROCEDURES
D. TYPE “2” OPERATION
Before proceeding with this type of operation, attach the first
external temperature probe 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

CARE and SAFETY PRECAUTIONS
CAUTION:
Improper usage can cause injury and physical damage.
For your own safety, please observe the following precautions.
"!
Temperature may reach as high as 500°C when turned ON.
- Do not touch the heating element inside the pre-heater.
- Do not expose skin to infra-red light for long periods.
- Prolonged exposure may damage the skin tissue.
"!
Handle with care
- Never drop or sharply jolt the unit.
- Contains delicate parts such as IR tubes that may break if
the unit is dropped
- Do not spill any liquid to the system.
"!
Do not tamper the electrical control unit or any wiring inside
the device.
"!
Disconnect plug from main power source if the device will not be
used for a long period.
-
Turn off power during breaks, if possible.
"!
Allow ample time for the equipment to cool down before com-
mencing maintenance.
"!
Use only genuine replacement parts. Turn-off power and let the
unit cool down before replacing any component.
