P48 = Extension of the anti-reset-wind up
Range: from -30 to +30 % of the proportional band.
NOTE: a positive value increases the high limit of 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).
P49 = 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.
P50 = Operative set point alignment at instrument
start up
0 = At start up the operative set point will be aligned to the
set point selected according to the digital input status.
1 = At start up the operative set point will be aligned to the
measured value, the selected set point value will be
reached by the programmed ramp (see Grd1 and
Grd2 operative parameters).
NOTE: if the instrument detects an out of range or an
error condition on the measured value it will ever operate
as described for P50 = 0.
P51 = "Loop break alarm" function.
dIS =
Alarm not used
Enb = The alarm condition of the "Loop break alarm"
(LBA) will be shown by the OUT 4 LED only.
EnbO = The alarm condition of the "Loop break alarm"
(LBA) will be shown by the OUT 4 LED and by
the OUT 4 relay status.
NOTES:
1) The alarm 3 and the "Loop break alarm" are in OR
condition on the same output (OUT 4).
2) The alarm 3 action type is programmed by P31
parameter.
3) The loop break alarm reset type is programmed by
P15 parameter.
4) For more details see "Loop Break Alarm function" at
pag 19.
P43 = Output safety value
This parameter is skipped when no one of the output is
configured as control output or P42 = 0.
It can be set
- from 0 to 100 % when one control output is selected
- from -100 % to 100 % when two control outputs are
selected
P44 = 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
P45 = Digital filter on the retransmitted value
This parameter is available only when P5 = Pv.rt.
It is possible to apply to the retransmitted 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
P46 = Control action type.
This parameter is skipped when none of the output is
configured as control output.
Pid = The instrument operates with a PID algorithm.
Pi
= The instrument operates with a PI algorithm.
P47 - Set point access
0
only SP is accessible.
1 only SP and SP2 are accessible.
2 all 4 set points are accessible.
