<Peak Torque Check – Angle Control>
P
For Angle Control operations, the High and Low Torque limits are either set by the engineering
specification for that specific fastener or by determining the acceptable limits from a study of known
good and bad assemblies. The High Torque limit will stop the fastening process for Angle Control
operations if it is reached before attaining the desired angle.
PEAK TORQUE HIGH LIMIT
Reduced joint compression.
Increased joint friction.
Incorrect parameter set-up.
PEAK TORQUE LOW LIMIT
Increased joint compression.
Reduced joint friction.
High initial prevailing torque.
Incorrect parameter set-up.
Reject condition caused by another monitor item reject.
