4.1.8 Guaranteed Soak Limits
To access the guaranteed soak limits, select “G-Soak Limits” from the Edit menu button on the
Program Entry screen. The Guaranteed Soak Limits screen is used to set the control tolerance for
guaranteed soak steps when in program operation. When the process variables deviate from their
set points by more than the soak limits, the program time will stop until the process variables re-enter
the soak bands. These limits apply to each step in the program and only need to be set once.
Figure 4-8 Guaranteed Soak Limits
To change a limit, touch the desired loop in the list, enter the new limit setting on the numeric keypad
and press ‘Enter’ when finished. The new limit value will then be shown in the list view for the
selected control loop.
If soak limit is set too tight, i.e., a very small deviation value from set point, it could prevent
the program from operating as desired because the process may not be able to be
controlled to such a tight limit setting.
Once all entries have been made, press the “Return” button to get back to the Program Entry screen.
