6.2.2Final Torque Monitoring
Torque Monitoring is a continuous process whenever the system is operating. Final Torque monitor-
ing uses the torque value detected at the completion of fastening.
• In Torque Control method, the Final Torque value and Peak Torque values will be identical except
in cases where Torque Recovery (Section 6.5) is enabled. In Torque Control method, the Final Tor-
que High and Low Torque limits are only selectable when Torque Recovery is enabled, and are typi-
cally set based upon the engineering specification for that specific fastener.
TORQUE CONTROL – TORQUE RECOVERY ENABLED
REJECT TYPE CAUSES
FINAL TORQUE HIGH LIMIT
Excessive chatter of the torque signal due to slip stick friction.
Incorrect parameter set-up.
FINAL TORQUE LOW LIMIT Reject condition caused by another monitor item reject.
