Temperature specifications
The following temperature limit values apply when using the system components:
The controller components, including compact system, servo amplifiers, measurement transducers, as
well as ErgoSpin hand-held nutrunners are equipped with temperature sensors for protection against
overheating.
The limit temperatures, which trigger an error in the system if they are exceeded, can differ. They depend
on the module (controller, measurement transducer, etc.) and the installation location of the sensors
within the module (see table 4–20).
For diagnosis purposes, the BS350 operating system provides an overview of the current system status
under System test  Tightening cell info  Temperature. This overview is an aid for evaluating the
temperature conditions in the system. Using this and the limit temperatures from Table 4–20, it is possible
to assess whether there are sufficient reserves in the system.
