4 Operating Guidelines
4.1 Temperature decrease (SETBACK) and
automatic switch-off time (AUTO-OFF) with
connected Switching Tool Stand
The SETBACK time and AUTO-OFF time can be set at the control
unit (WD1, WD2, WD1M, WD2M and WR 3M units), or are
permanently specified (WSD and WRS units).
After placing the soldering tool in the Switching Tool Stand, the
temperature decreases and/or the system shuts down, depending on
the setting at the control unit. The respective switching action is
displayed in the following table.

Temperature switching action after placing the soldering tool in the
Switching Tool Stand
0 0 The soldering tool is switched off in the holder 2) .
ON 0
The soldering tool is regulated in the holder 2) down to STANDBY
temperature 3) .
0 Time
The soldering tool is switched off in the holder 2) after the OFF time
has elapsed.
ON Time
The soldering tool is regulated in the holder 2) down to the STANDBY
temperature 3) and is switched off after the OFF time has elapsed.
Time 0
The soldering tool is regulated in the holder 2) down to STANDBY
temperature 3) after the SETBACK time has elapsed.
Time Time
The soldering tool is regulated in the holder 2) down to the STANDBY
temperature 3) after the SETBACK time has elapsed and is switched
off after the OFF time has elapsed.
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.
2) Outside the Switching Tool Stand, 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.
