Theta Controller
NOTE:
Programming changes are stored after exiting current menu and returning to run screen.
2.8.1 Setup Menu: 1. Jobs
Jobs controls tool operation for tightening a fastener: one to 16 and one TC/AM (Torque Control,
Angle Monitoring) Step with up to three optional Smart Steps. Most controllers operate with a
single Job and Task with one or two Steps. Users must have ADMINISTRATOR or SETUP
access in order to modify Job settings. This includes Wizard, Manage and Step parameters.
The Wizard automatically appears after selecting Jobs if a tool is attached and a Job or Task is
added. The Wizard sets a Job or Task for simple or complex fastening cycles using the optional
Smart Steps.
If no tool is attached, or if at least one Job exists, the Job tab appears allowing for advanced user
programming.
2.8.1.1 Wizard Screens
Wizard Screens
The Wizard assists with programming the controller to assign a Job, which consists of one
Audit Step with optional Smart Steps. To function, the Wizard requires a tool to be connected.
It automatically appears when there are no configured jobs or when adding a new job. The
Wizard presents programming parameters and gives a list of strategy controls. These controls
are explained further in this section.
TORQUE (TC/AM): Torque Control with Angle Monitor. The controller
shuts off the tool when the tool reaches the target torque value. The controller
also monitors angle which can indicate changes in joint rate. Audit torque and
angle results must fall within their specified limits for the fastening cycle to be
acceptable.
Thread Direction – for tightening a right hand fastener use CW, clockwise. Use CCW, counter-
clockwise for left hand fasteners.
