66
Default value: OFF.
TIME OF SMART FUNCTION - Group 2
Available: Only when SMART (TUNE) function is active.
Upper display: During the automatic computation of the filter time constant the upper display
shows the time constant selected by the algorithm. During the process analysis the
upper display shows the elapsed time from the step change; the time format is
mmm.ss (minutes and seconds). The maximum is 500 minutes, after this period the
SMART will be disabled.
Lower display: RLTM
Default value: Not applicable.
STEP FOR SMART FUNCTION - Group 2
Available: Always.
Upper display: Value of the step change used by the SMART (TUNE) function to estimate the
process parameters.
Lower display: AT.STP
Range: From -25.0 to 25.0%.
Default value: 10.0%
PROPORTIONAL BAND - Group 2
Available: Always.
Upper display: Proportional band value. Changes to this parameter are inhibited when ADAPTIVE
algorithm is active.
Lower display: PB
Range: From 1 to 10000%.
Default value: 100.
INTEGRAL TIME - Group 2
Available: Always.
Upper display: Integral time value. Changes to this parameter are inhibited when ADAPTIVE
algorithm is active.
Lower display: TI
Range: From 0.1 to 99.9 s.; above this value the display blanks and integral action is
excluded.
Default value: 5.0.
DERIVATIVE TIME - Group 2
Available: Always.
Upper display: Derivative time value. Changes to this parameter are inhibited when ADAPTIVE
