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.

ð The PCBs will only be fed into the module it the next module is empty. This

way, the PCBs are prevented, for example, from remaining too long in the

module due to a jam. However, this function can extend the cycle times.

Permanently fixing PCBs

ü To permanently fix PCBs during processing:

a) Activate the [Fix horizontal permanently] checkbox.

ð The PCBs are aligned in the module and then laterally fixed until processing is

completed. If the checkbox is not activated, the PCBs are only aligned and then

released again. You can activate this function separately for all available fluxer

and soldering modules

Manually compensating for the PCB deflection

Due to the heating and weight of the components, the PCBs get bent during pro-

cessing. Thereby, the distance [Z] from the solder nozzle to the soldering joint

changes. The machine corrects this error if an offset value is specified. The control-

ler takes into account the deflection and corrects the distances accordingly.

ü To compensate the [Board deflection] in machines without deflection measure-

ment:

a) Select the current soldering module from the [Data source] dropdown menu.

b) Determine the deflection of the board at the point of greatest deflection. This

is generally a point in the middle of the PCB.

c) Enter the deflection in [mm] into the [Correction] input field. Enter a positive

value if the board bends downwards. Enter a negative value if the board bends

upwards.

ð The deflection of the board is now taken into account by the controller and the

[Z] distances to the solder joints are corrected accordingly.

6.9.10 Settings of the Versaeye inspection system (option)

If the Versaeye inspection system must be used in the soldering program, it must

be configured in the machine control.

With regard to this, please also read the Versaeye inspection system (option)

[}269]chapter.

In order to use the Versaeye inspection system in the soldering program, the Exit

unit must be enabled in the soldering program.

Activate the [Exit unit] in the soldering program

ü Activate the [Exit unit] in the soldering program:

a) In the [General soldering program data] dialog, enable the module checkbox at

level 1.

ð The [Exit unit] module is now enabled and can be used in the soldering pro-

gram.

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.

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 indicates how often

the dialog has already been opened.
