Defining the pressure-gauge threshold
− This function can be used to define the maintenance interval of
the unsoldering tool. Here the value in mbar at which the electric
pressure gauge issues a warning signal when the intake system is
contaminated (LED (3) of the vacuum pump switches from green
to red) is defined. The set value is dependent on the suction
nozzles used.
− Factory setting: -600 mbar
Settable: -400 mbar to -800 mbar
1. System (tips and filter) must be free
2. Select the menu item LEVEL in Menu 2.
3. Set the LEVEL pressure value with the UP or DOWN button.
The LED control check switches back and forth between red and
green. Use the UP button to increase vacuum by 50 to 80 mbar,
pinch the vacuum tube and check whether the control lamp
switches from green to red.
4. Proceed to the next menu item with the button ┌ 1 ┐ (back) or
┌ 2 ┐ (forward).
Setting the station identification (ID code)
When the optional USB port is used, several WR 3M repair stations
can be activated and remote-controlled to their full operational
extent. To this end, each station requires a station identification
(ID code) so that it can clearly identified.
1. Select the menu item REMOTE ID in Menu 2.
2. Enter an ID with the UP or DOWN button
(possible values 0 – 999).
3. Proceed to the next menu item with the button ┌ 1 ┐ (back) or
┌ 2 ┐ (forward).
Note Press button ┌ 3 ┐ to exit the menu item without changes (EXIT).
Executing the calibration function (Factory Calibration Check)
With the FCC function you can check the temperature precision of
the repair station and even out possible deviations. For this purpose,
the soldering-tip temperature must be measured with an external
temperature meter and a temperature measuring tip assigned to the
soldering tool. The corresponding channel must be selected prior to
calibration.
