7.4 Temperature Validation
To validate is to check the built-in temperature sensor using an external
measuring system. The validation set consisting of a type K thermocouple
and a holder was designed for this purpose. Validation helps boost the
reproducibility of welds. The validation process consists of several stages.
These stages are:
1. Choose temperature Validation menu
To be able to execution a validation, an initialised device is required. The
Validate sequence is called up via the corresponding symbol in the menu.
Only the Supervisor user group has access to the validation icon in the menu.
2. Install blade
Close the cover after the blade is inserted. The device now runs with the
drives to the positions for validation. The cover then opens automatically.
3. Click in validation set
The validator sensor is clicked into the holder provided for it, see Chapter
5.2 Familiarizing yourself with the device. Once the sensor is locked into
place, close the cover and press the Start button.
The cable of the temperature sensor must be free to move .
Use only a calibrated gauge for the temperature measurement .
An automatic sequence controls three predefined blade temperatures for
10 seconds each. The predefined temperatures are displayed on the
touch screen as soon as they are reached. The validation is finished when
the cover opens.
4. Remove validator set
The sensor can now be removed from the holder. Close the cover. The drives
are brought back to the starting position.
5. Remove blade
To finish the process of validation, you must remove the blade with
the blade remover tool and then exit the Validate menu by pressing
the Cancel button.
If the user executes an abort, please follow the instructions on the
operator control .
