Theta Controller

2.8.1.5 Setup: Step Button

Step Button Screens
Step settings only affect the selected Job/Task. There can be only one audit step per Task. 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/right arrow keys to select the tabs/steps for
modifying.
Low Torque – The minimum peak torque for an acceptable tightening cycle (required for this
step). 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 tool illuminates. 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 (required for this
step). If the actual angle exceeds this limit the tightening cycle will be flagged as NOK and the
RED LED on the front panel and tool illuminates. 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 will be flagged as a NOK and the YELLOW LED
on the front panel and tool illuminates. Must be less than High Angle. Units are degrees of
rotation.
Bailout on High Angle – Determines if the tool stops when the High Angle limit is exceeded.
YES the tool stops if High Angle limit is exceeded; NO opens a new parameter so that a High
Angle Bailout limit can be set.
Speed – The velocity of the output of the tool during this step before any Downshift Mode
activates. Units are RPM. Required for this step. Must be greater than 0.
Acceleration - The rate the tool gets up to Speed in RPM/s (revolutions per minute per second).
Required for this step. Should be greater than 1000 RPM/s.
Downshift Mode – Selects the type of spindle inertia control toward the end of a tightening
cycle.
Programming
Options Screens
Name – Provides an identifier for the step.
Use the up/down arrows to spell with letters or
use the numeric keypad.
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 (required for
this step). If the actual torque exceeds this
limit the tightening cycle will be flagged as
NOK and the RED LED on the front panel
and tool illuminates. Must be greater than
Torque Target and less than or equal to the
rated torque marked on the tool.
