7.5.4 Defining a tightening program
The tightening program coordinates the tightening process or sequence. It is divided into various
tightening steps, where tightening parameters are set.
Basic commissioning is carried out with small-scale tightening programs. They consist of a:
•Start step
• Single tightening step
• End step
The following describes how to generate programs for tightening and loosening a bolt.
7.5.4.1 Tightening program for tightening a bolt
The tightening program for tightening a bolt starts the nutrunner clockwise. The following example shows
all the steps this requires.
To generate a new tightening program:
1. In BS350 click File New Tightening programs.
2. Select a program number, e.g. 1.
3. Assign a name to the tightening program, such as Tightening test by overwriting the existing
program name n.a. (not available). (if program number 0 is selected, "n.a." is not displayed).
4. Click Program info and enter a comment for the tightening program in the Program info dialog.
5. Confirm your comment with OK.
The Program info dialog closes and the text Program info is underlined. Move the mouse over the
button and the comment is displayed as a tooltip.
6. Select the end step and click the symbol .
A single tightening step is added before the end step (see Figure 7–23).
Programs from the machine capability examination are already included on the device at the time of
delivery. You can use these programs as the basis for your own tightening programs.
Please find information on the commissioning of the Nexo cordless Wi-Fi nutrunner and on the definition
of tightening programs in the "Nexo" documentation.
