P

For Torque Control operations, the High and Low Angle 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 Angle limit will stop the fastening process for Torque Control
operations if it is reached before attaining the desired torque.

TORQUE CONTROL

REJECT TYPE

CAUSES

HIGH ANGLE LIMIT

Increased joint compression.
Reduced joint friction.
High initial prevailing torque.
Incorrect parameter set-up.

LOW ANGLE LIMIT

Reduced joint compression.
Increased joint friction.
Reject condition caused by another monitor item reject.
