3. Commissioning

Assemble soldering iron rest (see exploded drawing).
Place the soldering iron in the safety rest. Insert the
soldering iron plug into the connection bush (7) of the
control unit and lock by turning to the right. Check that the
power supply corresponds to the specifications on the type
plate and that the power switch (1) is in the OFF position. On
version that can be switched, set the voltage on the selec-
tion switch (set in the factory to 240 V). Connect the control
unit to the power supply. Switch on the unit at the power
switch (1). When switching on the unit, a self-test is carried
out in which all display elements (2) are switched on briefly.
The electronic system then switches automatically to the
actual temperature and displays this value. LED (5) illumina-
tes. These light emitting diodes are optical regulator moni-
tors. Constant illumination means that the system is heating
up. The blinking light signals that the operating temperature
has been reached.
Setting the temperature
The digital display (2) shows the actual value temperature.
By pressing the UP or DOWN key (3) (4) the digital display (2)
switches to the setpoint. The setpoint can be changed by
tapping or by firmly pressing the UP or DOWN button (3) (4)
in the desired direction. Pressing the button will change the
setpoint quickly. The digital display (2) returns automatically
to the actual value approximately 2 seconds after releasing
the button.
Standard setback
If the soldering tool is not used within a period of 20 minu-
tes the temperature will be automatically reduced to a
standby temperature of 150 °C (300 °F). After three
setback periods (60 min.) the "AUTO OFF" function will be
activated and the soldering iron will be switched off.

(State (not USA) upon delivery: hard grounded, plug is not inserted)
Activating the standard setback function:
When switching on the unit press the "UP" button until "ON"
appears in the display. The setting is saved when the "UP"
button is released.Use the same process to switch the unit
off. "OFF" will appear in the display (state upon delivery).
The use of very fine soldering tips may have a negative
effect on reliable function.
Maintenance
The transition between the heating element / sensor and the
tip of the soldering iron may not come in contact with dirt,
foreign particles or become damaged, since this affects the
precision of the temperature control.
4. Equipotenzial bonding (not USA)
The various circuit elements of the 3.5 mm jack bush make
4 variations possible:
Hard-grounded:
No plug (delivery form)
Equipotential bonding:
With plug, equalizer at center
contact (impedance 0 ohms)
Potential free:
With plug
Soft-grounded:
With plug and soldered resistance.
Grounding via set resistance value.
