Product description
Controller for use in safety-critical tightening.
The controller is primarily used as a control and monitoring
unit for one or more tools at a workstation. Depending on
the peripheral devices that are procured, the controller can
also be installed outside of the work environment.
Software is already installed on the controller. The tighten-
ing settings must be carried out by a qualified person using
the controller or remote PC software (mProRemote) in
order to start fastening work. For further information
regarding software operation, please reference the Pro-
gramming Manual.
Nutrunner controllers with the suffix STO in the type name
are equipped with the STO safety function, see Chapter 9
STO safety function, Page 16.
