Operation and settings
Channel selection
The digital display can be set to Channel 1 (temperature control) or Channel 2 (feed) by
pressing the channel selection key (7). The channel that is currently displayed is marked by
a red/orange LED above the socket (6) or (8).
If no keys have been activated, the unit will switch automatically to Channel 1 after approx.
10 sec and show the actual temperature.
Temperature setting (Channel 1)
If no keys have been pressed, the digital display (2) will show the actual temperature. Pressing
the "Up" or "Down" key (3) (4) will switch the digital display (2) to the current setpoint value.
The setpoint value (blinking display) can be changed in the desired direction by touching or
continuously pressing the "Up" or "Down" key (3) (4). If the key is pressed continuously, the
setpoint value will change rapidly. The digital display (2) will automatically return to the
actual value approximately 2 seconds after the key is released.
Feed setting (Channel 2)
After switching to Channel 2, the digital display (2) will show the speed in the SFC mode or
the feed period in the SFA mode. This value can be changed in the desired direction by
touching or continuously pressing the "Up" or "Down" key (3) (4). If the key is pressed
continuously, the setpoint value will change rapidly. If no keys are pressed, the unit will
automatically switch to Channel 1 after approximately 10 seconds and show the actual
temperature.
Setting range:
SFA mode – feed period (solder)
SFC mode – speed
Rapid feed:
Simultaneous pressing of the "UP" and "DOWN" keys advances the
solder wire at max. speed (100%).
Recommended for advancing the filler wire after the solder roll is
replaced.

(10ms intervals)

SFA / SFC
mode switch:
Press the channel selection key (7) continuously and set the desired
mode with the "UP" key (3). The new operating mode will appear on
the display.
Adjusting the temperature window
Press the channel selection key (7) and " Down " (4) simultaneously. The blinking value (in
°C/°F) of the current temperature window will appear on the display (factory-set to "000").
The factory setting "000" means:
Temperature monitor circuit has been switched off and the unpowered contact (15) is always
low-resistant.
°C display
The setting " 001 – 099 " corresponds to the following:
Size of the temperature window + - 1°C to + - 99°C
°F display
The setting " 001 – 178 "corresponds to the following:
Size of the temperature window +- 1°F to +-178°F
Unpowered contact (potential independence)
If the actual temperature of the soldering tool is within the temperature window (tolerance
width), the contact (15 ) will be low-resistant. If the temperature is outside the temperature
window, this will be indicated on the display (2) as "HI" (temperature too high) or "LO"
(temperature too low) at 2 second intervals. The contact (15) is high-resistant.
The transistor output of an optocoupler functions as the unpowered contact of the unit. Care
must therefore be taken to note the polarity of the voltage to be applied.
PLUS (+) at Pin 2
MINUS (-) at Pin 3
This contact can be loaded with max. 24V / 20mA
