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 corre-
sponds 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 selection 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 temperatu-
re and displays this value. LED (5) illuminates. These light
emitting diodes are optical regulator monitors. Constant illu-
mination means that the system is heating up. The blinking
light signals that the operating temperature has been rea-
ched.
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.

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.
