P32 = P32 = P32 = Minimum value of the integral time P32 = P32 = Minimum value of the integral time Minimum value of the integral time Minimum value of the integral time Minimum value of the integral time
calculated by the SMART algorithm. calculated by the SMART algorithm. calculated by the SMART algorithm. calculated by the SMART algorithm. calculated by the SMART algorithm.
This parameter is present only if P27 is different
from 0.
It is programmable from 1 second (00.01) to
2 minutes (02.00).
P33 = P33 = P33 = P33 = P33 = Device status at instrument start up. Device status at instrument start up. Device status at instrument start up. Device status at instrument start up. Device status at instrument start up.
This parameter is skipped when P26 = OFF.
0 = the instrument starts in AUTO mode.
1 = It starts in the same way it was left prior to
power shut down.
P34 = NOT AVAILABLE P34 = NOT AVAILABLE P34 = NOT AVAILABLE
P34 = NOT AVAILABLE P34 = NOT AVAILABLE
P35 = Timeout selection P35 = Timeout selection P35 = Timeout selection P35 = Timeout selection P35 = Timeout selection
This parameter allows to set the time duration of
the timeout for parameter setting used by the
instrument during the operating mode.
tn. 10 = 10 seconds
tn 30 = 30 seconds
P36 = Digital filter on the measured value P36 = Digital filter on the measured value P36 = Digital filter on the measured value P36 = Digital filter on the measured value P36 = Digital filter on the measured value
It is possible to apply to the displayed value a
digital filter of the first order with a time constant
equal to :
- 4 s for TC and RTD inputs
- 2 s for linear inputs
noFL. = no filter
FLtr = filter enabled
P37 = Conditions for output safety value P37 = Conditions for output safety value
P37 = Conditions for output safety value P37 = Conditions for output safety value P37 = Conditions for output safety value
0 = No safety value (see"Error Messages" Chapter)
1 = Safety value applied when overrange or
underrange condition is detected.
LFS-1-CC.P65 16
2 = Safety value applied when overrange
condition is detected.
3 = Safety value applied when underrange
condition is detected.
P38 = Output safety value P38 = Output safety value P38 = Output safety value
P38 = Output safety value P38 = Output safety value
This parameter is skipped when P37 = 0
This value can be set
- from 0 to 100 % when P7 is different from 4
- from -100 % to 100 % when P7 is equal to 4
P39 =Extension of the anti-reset wind up P39 =Extension of the anti-reset wind up
P39 =Extension of the anti-reset wind up P39 =Extension of the anti-reset wind up P39 =Extension of the anti-reset wind up
Range: from -30 to +30 % of the proportional
band.
NOTE NOTE NOTE NOTE: a positive value increases the high limit of NOTE
the anti-reset-wind up (over set point) while a
negative value decreases the low limit of the anti-
reset-wind up (under set point).
P40 = Control action type P40 = Control action type P40 = Control action type P40 = Control action type P40 = Control action type
Pid - the instrument operates with a PID algorithm.
Pi - the instrument operates with a PI algorithm.
P41 = Set point indication P41 = Set point indication P41 = Set point indication P41 = Set point indication P41 = Set point indication
Fn.SP = during operative mode, when the
instrument performs a ramp, it will show
the final set point value.
OP.SP = during operative mode, when the
instrument performs a ramp, it will show
the operative set point.
