STwrench User Guide Working with Power Focus
9836 4134 01 Edition 2.9 217 (326)
The tightening strategies available are those provided by Power Focus, and not the strategies described in
this manual, which are provided by ToolsTalk BLM.
The LEDs behavior is also dictated by Power Focus, so the LED settings performed on the STwrench with
ToolsTalk BLM do not have any effect in this mode.
There are several ways to connect the STwrench to Power Focus:
• IRC-B radio module interface
• IRC-Z radio module interface
• IRC-W radio module interface
• STwrench Cable Box interface
15.1 Interface with IRC-B Radio Module
Ensure that the IRC-B radio module is installed in the STwrench (see the chapter QAT IRC-B / IRC-Z
radio modules for more information about the installation).
To allow the IRC-B radio module work with the remote device (Power Focus), you must execute the
pairing procedure. This is necessary only once, the first time you connect the STwrench to Power Focus.
Here is a description of the pairing procedure:
1. Turn on the STwrench
2. During the cell and gyroscope zero automatic adjustment, press the UP, RIGHT and BARCODE
buttons on the wrench keyboard in that order:
