Select if applicable:a.
Override Enable : If enabled, checks bolt yield condition by enabling slope monitoring.x
Fail Yield Override : If enabled, triggers failure during fastening operation when yield
condition is detected.
x
In the Point of Peak Slope field, enter a percentage value to identify the drop in the
Torque/Angle slope from the peak slope stored during the tightening, that will stop the tool at
the yield point of
the fastener.
b.
In the Slope Interval field, enter a value for number of degrees of tool socket rotation over
which the Torque/Angle gradient will be calculated.
c.
In the Angle into Yield field, enter a value for number of degrees past yield detection that
the bolt will be rotated.
d.
At Gradient & Dual Slope, select
to view the contents:6.
If enabled, do as follows:a.
Select any one:x
Single Slope Enable : Gradient checks are performed using Slope A limits only.x
Dual Slope Enable : Gradient checks are performed using Slope A and Slop B
limits.
x
In the Slope Interval field, enter a value for number of degrees of tool socket rotation over
which the Torque/Angle gradient will be calculated.
b.
In the Slope A High
Limit field, enter a value for high limit of slope in region 'A'.c.
In the Slope A Low Limit field, enter a value for low limit of slope in region 'A'.d.
In the Slope B High Limit field, enter a value for high limit of slope in region 'B'.e.
In the Slope B Low Limit field, enter a value for low limit of slope in region 'B'.f.
In
the Torque Crossover Point field, enter a torque value that is used to transition from
region A to region B during Dual slope monitoring.
g.
In the Angle Crossover Point field, enter an angle value that signifies the start of
transition from region A to region B.
h.
At Stick Slip, select
to view the contents:7.
If enabled, do as follows:a.
In the Threshold Torque (%) field, enter a percentage value where if torque decreases
by this amount stick slip has started to occur.
x
In the Occurrence field, enter a value to detect the number of times the measured x
