Create .dat-file

Tapping Create .dat-file will store the most important productand control data, by default on the connected USB stick. Thisinformation can be helpful for the maintenance support.

Calibration point

Set the Y-axis calibration point. Refer to paragraph 6.7.1 fordetails.

Restart controller

This will reboot the DA-40T system.

6.7.1 Setting the calibration point

To calibrate the bending depth calculation the calibration pointmust be programmed. This parameter defines the Y-axisposition when the tools are closed. In other words, the Y-axisposition that corresponds with the situation where the lowestpoint of the punch is at the same level as the upper side of theV-die (pinching point with sheet thickness = 0).

This procedure has to be repeated each time the height of the tools that are mounted in the machine have changed.

To set the calibration point, tap on the ‘calibration point’ soft keyon the Maintenance tab in Settings mode.

A practical way to calibrate the machine is to place a sheet ofmaterial with known thickness between the tools and find the Y-axis position at which the punch just touches the sheet (pinchingpoint) using the manual positioning function.

The first parameter indicates the Y-axis position. The second parameter is to define the thickness of the sheet that has been used for the calibration. When the thickness value is entered, the calibration point is calculated automatically.

6.8 System information

On this tab system information can be found. It shows the actualsoftware version; software update functionality is available hereas well.

With ‘update software’ the control can install a software update set from a USB stick. The directory browser will help to selectthe desired update and initiate the installation process.

Backup system

The backup system function makes a complete system backupto a USB stick. A unique time stamped file is written on the USB stick. This backup holds Delem software, OEM specific data as well as the user’s files.

Restore system

The restore system function can be used to restore an earliermade backup of the system. During the process selection of what will be restored can be done.

Offline software

The offline software function generates an offline software setup file on a USB stick. This setup can be used to update an existing offline software. Using the matching offline software version withthe control software ensures optimal compatibility of functions.


If the service row is pressed for 2 seconds in Automatic mode orManual mode the DA-40T will enter its built-in diagnostic mode.

The diagnostic mode can be switched off by tapping the service row again.

These diagnostic screens are intended to be used onrequest of a service engineer from the machine manufacturer.
