4.7.17 EDIT SEGMENT TOLERANCE

Use this menu to edit the tolerance value assigned to this segment. The tolerance is a value from -
99 to 99, or OFF, that specifies a process variable limit for assured soak. If a positive value is
entered the process variable is assured to be no higher than setpoint + the tolerance value. If a
negative value is entered the process variable is assured to be no lower than setpoint - tolerance. If
OFF is specified no tolerance checking is done.

Whenever a loop is out of tolerance the status display will show a 'T' and the segment clock will
stop running. When the loop returns to within tolerance the segment clock will resume. If the
cumulative time out of tolerance for the entire segment exceeds the maximum out-of-tolerance
time specified for this profile, a tolerance alarm is generated.
