The device performs two safety checks at this point:

Correct Fitting Connection (CFC)
The device checks whether a fitting is attached and compares these data with the previously scanned in
data. If the deviation between both values is less than the tolerance referred to in the code, the welding
process begins. If the deviation lies outside the permissible tolerance then the device will report an error
and provides information about where the error could lie (see "Error patterns" Chapter 8).

Heat Control Function (HC).
The device calculates (based on welding parameters, the current device temperature and the ambient
temperature) whether this welding sequence can be performed completely. It is above all at high outside
temperatures or with large fittings that there could otherwise be overheating of the device and therefore
emergency switching off during the ongoing welding process.
The green >START< button lights up if the welding sequence can be performed completely. The welding
process can be started by pressing this button.
If the current device temperature is too high, the red >STOP< button lights up. A notice will appear in the
display concerning how long the device must cool down for before one can start welding again (the time
displayed here is an approximate time).
If the green >START< button lights up then pressing this button will start the welding process.
All relevant data are displayed on the screen during the welding process. The welding process is
monitored during the whole welding time according to the welding parameters prescribed by the scan
fitting code.
The welding process can be broken off at any time by pressing the >STOP< button.
The welding device automatically regulates the welding time according to the ambient temperature.
Therefore the welding times for identical fittings can vary.
The welding time is also displayed for simplified presentation as a status column.
The result is shown in the display after ending the welding cycle. The cooling time should be observed
according the fitting manufacturer's instructions. If the barcode for the fitting contains information about
the cooling time, this is displayed after ending the welding process. The cooling time is also displayed for
simplified presentation as a status column.
The cooling time can be ended at any time by pressing the >STOP< button. Breaking off of the cooling
process will be noted in the log. Also separation of the fittings from the connections leads to breaking off
of the cooling time.
