Theta Controller
Analyze Screens
Options Screen
Use the right arrow to move to the next tab or press the EXIT key, save the changes and return
to the run screen. See Section 2.5.1.6.
TRACE tab
This tab will plot a torque vs. time curve after
every tightening cycle. The Y-axis is scaled
from 0 to rated torque of the attached tool.
The X-axis has a variable scale to include the
entire tightening cycle.
Use the right or left arrow to move to the next tab or press the EXIT key, save the changes and
return to the run screen. See Section 2.5.1.6.
I/O tab
This tab indicates the live status of the
24VDC Inputs and Outputs. Forcing the I/O
on or off is also performed here. Users must
have the DIAGNOSTICS or
ADMINISTRATOR access level to force I/O.
Each pin, of the 24VDC connector, is
represented. Pin A is for supplying 24VDC to
the I/O elements. Pin V is the 24VDC Return
to complete the current loop. Pin B is the bus
for the Outputs. See section 4.1.4 for a
schematic. Pins L through U are for Inputs.
Pins C through K are for Outputs. See section
2.5.3 to assign elements to the pins.
If an Input or Output pin icon is Clear, that
means it is OFF, If the pin icon is Dark this
means the pin is ON.
There is a horizontal cursor under the pins.
Use the cursor keys to move the cursor. The
bottom left hand corner of the screen will
indicate which pin the cursor is at and what
element has been assigned to that particular
pin.
You can take manual control of the I/O by
using forcing. Pins can be force ON or OFF.
Applying a force means the pin will always
be in that forced state and will not toggle to
the opposite state; even though the system
requires it to toggle. This is useful for
troubleshooting signals that integrate with
other equipment.
Use the horizontal cursor under the pins to
select the pin to be forced. Press the ON
button to force it On, press the OFF button to
force it Off. When the force is no longer
required, press the REMOVE button to
remove the force and return the pin to system
control.
When forcing I/O changes during an
operation, the system provides a warning first.
