that the operating temperature has been reached.
Channel Selection
The digital display tan be switched to channel 1 or 2 by operating the channel selection
button (7). The currently displayed channel is identified by a red/orange light emitting diode
over connector (5) or (9).
The channel displayed tan be switched off by operating the ,,Up" and ,,Down" buttons (3) (4)
simultaneously. This is confirmed in the display with ,,Off ".
To activate a channel that has been switched off, the channel is selected, if necessary, using
the channel selection button, and switched on by pressing the Jp" and ,,Down" buttons (3)
(4) simultaneously. The current value is displayed in the display.
Maintenance
The transition between the heating element / Sensor and the tip of the soldering iron may not
of the temperature control.

3. Equipotential bonding

The various circuit elements of the 3.5 mm jack bush make 4 variations possible:
No plug (delivery form)
Hard-grounded:
With plug, equalizer at Center contact (impedance 0 Ohms)
Equipotential bonding:
Potential free: with plug
With plug and soldered resistance. Grounding via set
Soft-grounded:
resistance value.
No plug and Separation of bridge Bi on the control board.
Grounding via RC filter 100 k ohms / nF
For initial heating, coat the selective tinnable tip with solder. This removes any Oxidation or
and before storing the soldering iron, ensure that the tip of the soldering iron is well coated.
D not use aggressive fluxing agents.
O
Note: Always ensure the proper Position of the soldering iron tip.
These soldering irons have been adjusted for an average-size tip. Deviations tan occur due
to exchanging of the tip or using other tip designs.
External imut unit WCB 1 and WCB 2 (oational)
The following functions are possible when using an extemal input unit,
The real temperature of the soldering iron tan be changed by -e 20 OC
by input of a temperature offset.
l Setback:
time tan be set at 0-99 minutes after the soldering Station has switched
to standby mode.
l Lack:
the soldering Station has been locked.
Switching the temperature display from OC to "F and vice versa.
Setting a temperature window (only with control units with Optical
coupler output). If the actual temperature is within the temperature
window, a potential-free contact (Optical coupler output) will be
switched through.
l Cal: Re-adjustment of the soldering Station (WCB 2 only).
