IP
Integral pre-load. This parameter is only
available when Pb is not 0.
Span:
- from 0 to 100% for one control output
- from -100 to 100% for two control
outputs.
C
Out 1 cycle time (in seconds).
This parameter is only available when
Pb is not 0.
Span: from 1 to 200 s.
C2
Out 2 cycle time (in seconds).
C2 is only available if Pb is not 0 and P5
is 5.
Span: from 1 to 200 s.
rC Relative Cooling gain.
This is skipped if Pb = 0 (ON/OFF action)
or P5 is not 5.
Span: from 0.20 to 1.00
OLP
Dead band/Overlap between H/C outs (in
% of the proportional band).
“OLP” is skipped if Pb = 0 (ON/OFF
action) or P5 is not 5.
A negative value shows a dead band
while a positive value shows an overlap.
Span: from -20 to 50%.
r L
Set point low limit (in eng. units).
Span: from min. range value (P2) to rH.
NOTE
NOTE NOTE NOTE NOTE: when rL value has been
chenged, if the SP and SP2 value are
lower than the new rL value, thay will be
alligned to the new rL value.
rH
Set point high limit (in eng. units).
Range:from rL to full scale value (P3).
NOTE
NOTE NOTE NOTE NOTE: when rH value has been
chenged, if the SP and SP2 value are
higher than the new rH value, thay will
be alligned to the new rH value.
- For two control outputs: from 1.5% to
99.9% (from 1.5% to 100.0% for model
0216) of the input span (P3-P2)
When the the SMART is ON (see section
5.2) the value of Pb is limited to that set
in P16-P17 (one control action) and to
that set on P16-P18 (two control actions).
When Pb parameter is set to 0, the
instrument performs an ON-OFF control;
the ti, td, IP, C, C2, rC, OLP, OLH and
tOL parameters are skipped and the
"output max. rate of rise" and SMART
functions are not available.
HS
Hysteresis for ON/OFF control action (in
% of P3 - P2 span).
This parameter is only available when
Pb = 0.
Span: from 0.1% to 10.0% of the input
span.
t i Integral time. Is skipped when Pb = 0
(ON/OFF action).
Span model 0316: from 0.1 to 20.0 mm.s
(minutes and tens of seconds).
Span model 0216: from 00.01 to
20.00 mm.ss (minutes and seconds)
Above this value the display becomes
dark and the integral action is excluded.
td Derivative time. This parameter is
skipped if Pb = 0 (ON/OFF action).
Span model 0316: from 0.00 to 9.59
mm.ss (minutes and seconds)
Span model 0216: from 0.00 to 10.00
mm.ss (minutes and seconds).
If 0 is set, the derivative action is
excluded.
