6.9.9 Soldering unit settings
In this example, the soldering module is provided with a compressed air heater
above and two pots.
Enabling the module
ü To enable the module:
a) In the [General soldering program data] dialog, activate the checkbox of the
module in level 1.
ð The module has now been enabled and is used in the soldering program.
Setting preheating temperature, preheating period
ü To set the preheating temperature and period:
a) In the [General soldering program data] dialog in level 2, click on the input
fields and enter the preheating temperature in [°C] and the prehating period in
[s].
ð The PCBs will thus be subjected from above to the preheating temperature for
the duration of [Preheating time].
Setting the conveyor speed
ü To set the conveyor speed:
a) In the [General soldering program data] dialog in level 3, click on the input field
of the conveyor section.
b) Enter the conveyor speed in [%] of the maximum possible speed value.
ð This is the speed at which the board is conveyed into the next module.
Enabling pots
ü To enable one or both pots:
a) Enable checkboxes in the [General soldering program data] dialog in level 4.
ð If a checkbox is enabled, the relevant pot is used in the soldering program.
Performing extended settings in the [General additional data] dialog
ü To perform extended settings:
a) Open the [General soldering program data] dialog.
b) Below Level 6, click on the
button in the corresponding module.
Open the [General additional data] dialog. The yellow square provides information
about how often the dialog has already been opened.

Park position and jam position
In the [Park position] input fields, you can define a position for the nozzle, which is
always approached when the process step has been finished. In this position, the
module waits for the next board. You can also approach this position manually.
In the [Congestion position] input fields, you can define a position for the nozzle,
which is always approached when the machine is somewhere congested with
boards.
Adjusting the process time manually
ü To adjust the process time manually:
a) Click on the [Process time] input field and enter a process time.
ð The process time is adjusted, and the time calculated by the controller for this
module is overwritten. When clicking on [Process time], the controller recalcu-
lates all process times. The process time adjusted by you is overwritten.
First always empty the next module
ü The PCBs shall only be fed into the next module if this module is empty:
a) Activate the [Empty module always] checkbox.
