If anegative value is entered the process variable is assured to be no lower than setpoint - tolerance. IfOFF 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 willstop running. When the loop returns to within tolerance the segment clock will resume. If thecumulative time out of tolerance for the entire segment exceeds the maximum out-of-tolerancetime specified for this profile, a tolerance alarm is generated.|----------------|Display: ¦ x SEGMENTyy ¦¦ SEG TOLRANCE?zz¦|----------------|The ? flashes.x is the profile designator [A-L].yy is the segment number [1-20].zz is the tolerance value for assured soak.4-56
