4.3 Monitoring Operation
4.3.1 Torque and Angle Values
The middle section of the Run Main screen on the IC-D displays torque and angle information for each tightening
operation. The larger value is the primary one, and it reects the strategy that applies to the selected Conguration.
In the cutout of the screen shown below, the strategy is Torque, so the primary value is the torque value. The smaller,
secondary, value below the torque value is, in this example, the angle measured value.
If this were an Angle strategy, the angle value would be the primary value.
Figure 24 - System Monitor
In this example, the torque value is shown in Nm units. The torque value shown always reects the Torque Units
parameter that was selected on the Quick Setup screen. For instance, if Ft-lbs had been selected instead of Nm, then
that is the torque unit that would be displayed. The angle control value is always shown in degrees. Note that both the
primary and secondary numbers show either a degree symbol or torque units, making it clear which parameter you are
viewing.
The LED display on the IC-M only shows the primary value after each tightening, as compared to both numbers on the
IC-D display. The text above the result shows the Conguration that was run, the step number for the result displayed,
and the tightening strategy.
4.3.2 Colored Status Indicators
Besides the torque and angle values that are displayed for each cycle, this section of the IC-
D Main screen also displays status indicators at the end of each cycle. When the torque and
angle are both within range, the green circle with OK in the middle is displayed to represent a
successful cycle.
When one or both values are out of range, independent status icons are used to indicate the
results. A yellow down arrow with a minus (-) sign indicates a value below the programmed low
limit, while a red up arrow with a plus (+) sign shows that the value is above the high limit. In the
example to the right, the primary number is high, while the secondary value is low. When one
value is within range, and the other is not, the space on the side of the value within range is left
blank, while the other side indicates either high or low.
When your Insight controller is programmed with limits other than torque and angle, the spaces on either side of the
primary and secondary dividers may both be blank, indicating something besides angle and torque is out of range, for
example, slope.
Each Ingersoll Rand hand-held spindle also has an indicator light on the spindle itself that mimics the screen status
indicators. If the fastening is within specication, the spindle light is green. If either the torque or angle value is above
the programmed high limit, the spindle light is red. When either value is below the programmed low limit, the spindle
light is yellow.
4.3.3 Gang Operations
When the tightening process involves multiple bolts that must be fastened in sequence, which is called a “Gang,” the
Main screen also displays a “Gang Complete” message following the completion of a successful gang assembly. This
is designated in the Conguration programming as having a gang that is greater than 0. The current gang status is
displayed on the screen and replaced with the gang complete message when the sequence has all pass cycles. You can
also reset the Gang count while on this screen. Press 0 (zero) on the number key pad once and the then Enter to reset
the Gang count. To reset the Auto Increment to a programmed Conguration. Press 0 (zero) two times and then press
Enter to reset the Auto Increment.
