OFF time
If the soldering tool is not in use, the heating for the soldering tool is deactivated after the OFF time
elapses. Temperature deactivation is performed independently of the set standby function. The actual
temperature is indicated by flashing LED and serves as a residual heat display. The display reads
„OFF".
As long as the soldering tool cools, the residual heat is displayed in the 1-channel display. Cooling
also flashes in the display.
For the 2-channel display, ° C / ° F flashes in the display of the corresponding channel.
As soon as the temperature falls below 50 °C (122 °F), OFF appears in the display and the backligh-
ting is deactivated.
Pressing the UP and DOWN buttons at the same time exits OFF mode.

Option 1 (factory setting):
Set the potential-free switching output to ES FE.
Limiting the adjustment range to ± 1-99 °C (±1-180 °F) based on a temperature locked using the
„LOCK" function.
The locked temperature therefore represents the middle of the adjustable temperature window.
Option 2:
Set the potential-free switching output to ES rob; ES FE / rob; ES rob / rob.
Starting from a set, locked temperature, it is possible to set a temperature window of ± 1-99 °C (±1-
180 °F) using the WINDOW function. If the actual temperature is within this window, the potential-free
contact (optocoupler output) becomes conductive.
