System stick A USB stick included in the scope of delivery that, amongst others, contains the installation program
for the operating system BS350, as well as the firmware and documentation.
Monitoring function The monitoring function keeps track that the upper and lower limits are complied with during the
tightening process by checking a monitoring parameter (e.g. gradient).
If the monitoring function has switching capabilities, the tightening step will be terminated immediately
if a limit is exceeded. If it is has no switching capabilities, the step result changes to NOK, even if the
target parameter has been reached.
Monitoring parameter The monitoring parameter is the measured quality (e.g. gradient) of a tightening step that must be kept
within specific limits in order for a tightening process to be performed safely. If the limits are violated,
the tightening step may be terminated.
Angle correction The angle correction is an additional parameter to measure the angle of turn. Since the angle of turn
is never measured directly on a bolt, but above the output drive, there is a small deviation between the
measured angle and the angle on the bolt as a result of the torsion of the output drive due to the
torque. This deviation can be avoided with an angle correction at the end of the tightening process
(never during tightening!). The angle value measured at the end of tightening after falling below the
torque threshold is then used as the target or last monitoring parameter (the torsion of the output drive
has then reset itself).
Target function The target function controls the process sequence of the tightening step by monitoring the target
parameter (e.g. torque) and ends the step if the parameter value has reached its target value.
Target parameter The target parameter is the measured variable (e.g. torque) of a tightening step, which must reach a
specific value (target value) for a tightening process to be performed successfully. The tightening step
is terminated once the target value has been reached.
Additional function The additional function defines further parameters for the tightening step. Although they have an effect
on the tightening process (e.g. start-up suppression, speed setting), additional functions cannot
interrupt it. They do not carry out an OK/NOK evaluation.
Additional parameters Additional parameters are the parameter values in a tightening step, which influence the tightening
process (e.g. target speed, torque threshold), but which cannot interrupt the tightening process.
