c) Read the new value and compare it with the value you noted down. The new
value may differ by ± 1% from the value noted down.
ð If the discrepancy is more than + 1% of the value you noted down:
d) Open the solder nozzle table and slightly increase the [Gradient] value, at most
by 5 units.
e) If the descrepancy is less than - 1% of the value you noted down:
f) Open the solder nozzle table and slightly reduce the [Gradient] value, at most
by 5 units.
g) Store the entries and re-perform a soldering wave height test.
h) Repeat these steps until the [Wave offset] value lies in the tolerance range.
i) In the [Manual movement] frame, click on the
button.
ð The solder pot is moved to the [Service] position.
3 mm
j) Check the height of the wave. In a 75% wave power of the maximum value, the
solder wave should lie still on the nozzle, i.e. make no horizontal or vertical
movement. At the same time, it features a height of about 3 mm.
ð The solder nozzle has been properly installed.

6.16 Flux unit Flux application module: flux control (option)
Function
The flux control system checks the soldering program in terms of choosing a certain
flux for soldering. If such record is available in the program, the control system
checks which flux is in the tank and compares it with the program data. If data coin-
cide, the program may be used for soldering. If not, a message appears, and the
program cannot be run. For proper functioning, specify the flux in the tank cor-
rectly. Flux can be specified manually or using a code reader.
Before starting operations, please read the For your safety [
}33] chapter and ob-
serve in particular its instructions on how to handle the flux material!
A detailed description of flux refilling can be found in the Supplementing flux ma-
terial storage [}372]chapter.
A detailed description of system cleaning, washing and air removal can be found in
the Disassembling and cleaning the flux material storage tank. [
}364]chapter.

Flux Tank Preparation and Initial Filling
ü Filling an empty tank:
ü A user logging into the system has respective rights.
ü The machine is in the operating mode [Maintenance mode] function.
a) Press the flux sprayer icon in the basic dialog window.
ð The [Flux unit 1] window appears.
b) In the [Switch functions] frame press the button to enable module mainten-
ance. When the module maintenance mode is active, this button turns yellow.
c) Open the flux storage door.
d) Prepare a flux can.
e) Make sure that you have prepared flux material of one grade only. Do not mix
up grades!
f) Fill the tank with flux, then bleed the system and flush it.
g) Close the flux storage door.
h) In the [Switch functions] frame press the button to deactivate module main-
tenance. When this mode is completed, the button turns grey.
i) Open the [Messages] input dialog and acknowledge all existing messages.
ð The process has now been completed.
