1) With the WSD and WMD devices, only the settings 0/0 and ON/TIME are possible, whereby the
respective time values for SETBACK (20 minutes) and AUTO-OFF (60 minutes) are permanently
specified. With these device types, deviating SETBACK times are only possible with the external
input device WCB2.
Outside the switching holder, the soldering tool always remains at the set specified temperature.

The holder function is activated after the first time the soldering tool is deposited.
3) The STANDBY temperature must be below the set specified temperature; otherwise the SETBACK
function is inactive.

6 Operating the device

6.1 Temperature decrease (SETBACK) and
automatic switch-off time (AUTO-OFF) with
connected switching holder
The SETBACK time and AUTO-OFF time can be set at the control
unit (WD1, WD2, WD1 M, WD2 M- and WR 3M devices), or are
permanently specified (WSD and WMD devices).
After depositing the soldering tool in the switching holder, the
temperature decreases and/or the system shuts down, depending on
the setting at the control unit. The respective switching behaviour is
displayed in the following table.
