Note
:When device is working with
SMART algorithm the Pb value will be
limited by P31 and P32 parameters.
HyS
Hysteresis for ON/OFF control action
This parameter is available only when
Pb=0.
Range: from 0.1% to 10.0% of the input
span.
ti
Integral time
This parameter is skipped if Pb=0 (ON/
OFF action).
Range: from 00.01 to 20.00 [mm.ss].
Above this value the display blanks and
integral action is excluded.
Note
: When the device is working with
SMART algorithm, the minimum value of
the integral time will be limited by P33
parameter.
td
Derivative time
This parameter is skipped if Pb=0 (ON/
OFF action) or P41 = Pi.
Range:From 00.00 to 10.00 mm.ss.
Notes
: When device is working with
SMART algorithm the td value will be
equal to a quarter of ti value.
IP
Integral pre-load
Ranges:
- from 0.0 to 100.0 % of the output span
if device is configured for one control
output.
- from -100.0 to 100.0 % of the output
span if device is configured for two
control outputs.
Cy2
Output 2 cycle time
This parameter is available only if P9 is
equal to rEv or dir.
Range:From 1 to 200 s.
Cy3
Output 3 cycle time
This parameter is available only if P11 is
equal to rEv or dir.
Range:From 1 to 200 s.
rC
Relative Cooling gain
.
This parameter is available only when
device is configured with two control
outputs and Pb is different from zero or
device is in manual mode.
Range: from 0.20 to 1.00
Note
: When the device is working with
SMART algorithm and P23 is set to On
the RCG value is limited in accordance
with the selected type of cooling media:
- from 0.85 to 1.00 when P22 = AIr
- from 0.80 to 0.90 when P22 = OIL
- from 0.30 to 0.60 when P22 = H2O
OLAP
Dead band/Overlap between H/C
outputs
.
This parameter is available only when
device id configured with two control
outputs and Pb is different from zero or
device is in manual mode.
Range: from -20 to 50 % of the
proportional band.
A negative OLAP value shows a dead
band while a positive value shows an
overlap.
rL
Set point low limit
Range: from initial scale value (P3) to
rH.
Note
: When P3 has been modified, rL
will be realigned to it.
rH
Set point high limit
Range:from rL to full scale value (P4).
Note
: When P4 has been modified, rH
will be realigned to it.
