Setting temperature deactivation (SETBACK)
When the soldering tool is not in use, the temperature is reduced to
the standby temperature after the set setback time has elapsed. The
setback state is indicated by a flashing actual value and "STANDBY"
appears in the display. Pressing the UP or DOWN button terminates
this setback state. Depending on the tool, the finger switch or the
switching holder deactivates the setback state.
The following setback settings are possible:
− "0 min": setback OFF (factory setting)
− "ON": setback ON (the system is controlled down to standby
temperature with the switching holder after the soldering bit is
stowed)
− "1-99 min": setback ON (individually settable setback time)
1. Select the menu item SETBACK in Menu 1.
2. Set the setback value with the UP or DOWN button.
3. Proceed to the next menu item with the button ┌ 1 ┐ (back) or
┌ 1·2 ┐ (forward).
Note In the case of soldering work with low heat requirements, the
reliability of the Setback function may be impaired.
Setting the automatic switch-off time (AUTO-OFF)
When the soldering tool is not in use, heating of the soldering
tool is switched off after the AUTO-OFF time has elapsed.
Temperature deactivation is performed independently of the set
setback function. The actual temperature flashes in the display and
serves as residual-heat indicator. "OFF" appears in the display. A
flashing dash appears in the display below 50 °C (150 °F).
The following AUTO-OFF time settings are possible:
− "0 min": AUTO-OFF function is switched off
− "1-999 min": AUTO-OFF time, individually settable
1. Select the menu item OFF in Menu 1.
2. Set the AUTO-OFF setpoint time value with the UP or DOWN
button.
3. Proceed to the next menu item with the button ┌ 1 ┐ (back) or
┌ 1·2 ┐ (forward).
