Program sequence
During the program sequence the temperature profile will run as described in Section 3.2. The current
program step will be displayed on the programming unit display and on the left LED display (29) of the base
unit.
STEP 1
: Sequence program step 1 – Preheating phase1 ends with acoustic signal
STEP 2
: Sequence program step 2 – Preheating phase2
STEP 3
: Sequence program step 3 – Reflow phase
COOLING
: Sequence program step 4 – Cooling phase ends with acoustic signal
As these program steps run, the current temperatures of the connected sensors can be shown by selecting
with the
arrow keys

.
NOZZLE TEMP
: Actual temperature of the top heater (nozzle)
PREHEATTEMP
: Actual temperature of the bottom heater
SENSOR1
: External Sensor1 (thermocouple type K) - optional
SENSOR2
: External Sensor2 (thermocouple type K) - optional
The programming unit display will also show remaining time (“
TIME REMAINING
“) of the given program
step.
The LED displays for the top heater and bottom heater on the right side of the base unit are used to visually
check the hot gas top heater and infrared bottom heater.
To start the de-soldering process it is necessary to press the
DESOLD.
key (desoldering) before beginning
the program sequence. The LED display “Desoldering the base unit” will illuminate and the vacuum tube on
the soldering head will descend. This will cause the vacuum (integrated in the nozzle) to be switched on
automatically at the end of the process. The vacuum must be switched off manually with the
VAC
key.
