Step settings only affect the selected Job. There can be only one audit step per Job. In the
Theta, that audit step is a Torque Control / Angle Monitor (TC / AM) strategy. The audit step
can have Smart Steps associated with it. Without the audit step the Smart Steps are deleted.
Each step is represented by its own tab. Use the left or right arrow keys to select the tabs/steps
to modify them.
Name – Provides an identifier for the step.
Use the up and down arrows to write a name
using the alphabet. Use the number keypad
for numbers.
Torque Target – The torque at which the
controller shuts off the tool (required for this
step). Should be greater than Low Torque and
lower than High Torque.
High Torque – The maximum peak torque for
an acceptable tightening cycle. If the actual
torque exceeds this limit the tightening cycle
will be flagged as NOK and the RED LED on
the front panel and the tool will illuminate.
Required for this step. Must be greater than
Torque Target and less than or equal to the
rated torque marked on the tool.
Low Torque – The minimum peak torque for an acceptable tightening cycle. If the actual
torque does not reach this limit the tightening cycle is flagged as NOK and the YELLOW LED
on the front panel and the tool will illuminate. Required for this step. Must be less than the
Torque Target.
Snug Torque – The point in this step when the controller begins to monitor the tool’s output
angle. Should be greater than 0 and less than Low Torque. A value of 50% of Torque Target is
a good starting point.
High Angle – The maximum peak angle for an acceptable tightening cycle. If the actual angle
exceeds this limit the tightening cycle is flagged as NOK and the RED LED on the front panel,
and the tool, will illuminate. Required for this step. Must be greater than Low Angle. Units
are degrees of rotation.
Low Angle – The minimum peak angle for an acceptable tightening cycle. If the actual angle
does not reach this limit the tightening cycle is flagged as a NOK and the YELLOW LED on
the front panel and the tool will illuminate. Must be less than High Angle. Units are degrees of
rotation.
Angle Bailout – Determines when to stop the tool on angle. Should be set equal to or above
High Angle. Units are degrees of rotation.
Downshift Mode – Selects the type of spindle inertia control toward the end of a tightening
