4.3.8.2 Program selector
The program selector is used to select the appropriate tightening program or tightening application for
hand-held nutrunners:
Fig. 4–34: Exemplary figure of program selector
The program selector is available in three versions:
• with 12 programs: Program 0-11
• with 16 programs: Program 0-15
By connecting the program selector to a 24-V interface (IM24V, inserted into the tightening controller/
communication unit), the appropriate input signal will be set to the interface depending on the switch
position. Here, the four inputs 0.0 to 0.3 are used as a 4-bit word. The program/application can therefore
be selected by assignment to the program selection bits
Prog0 to Prog3 (when connected to a tightening
controller) or FO x Seq0 to FO x Seq3 (when connected to a communication unit) in the PLC table.
