[2] dP - Decimal point position
Available:
Always.
Range:
0 to 3 when [1] SenS = Linear input;
0 or 1 when [1] SenS different from linear input.
Note:
Every change of the dP parameter setting will produce
a change of the parameters related with it (e.g.: set
points, proportional band, etc.).
[3] SSc - Initial scale read-out for linear inputs
Available:
When a linear input is selected by [1] SenS.
Range:
-1999 to 9999.
Notes: 1.
SSc allows the scaling of the analog input to set
the minimum displayed/measured value.
The instrument will show a measured value up to
5% less then SSc value and than it will show an
underrange error.
2.
It is possible to set a initial scale read-out higher
then the full scale read-out in order to obtain a
reverse read-out scaling.
E.g.:
0 mA = 0 mBar and 20 mA = -1000 mBar (vacuum).
[4] FSc - Full scale read-out for linear input
Available:
When a linear input is selected by [1] SenS.
Range:
-1999 to 9999.
Notes: 1.
Fsc allows the scaling of the analog input to set
the maximum displayed/measured value.
The instrument will show a measured value up to
5% higher than [4] FSc value and then it will show
an overrange error.
2.
It is possible to set a full scale read-out lower
than the initial scale read-out in order to obtain a
reverse read-out scaling.
E.g.:
0 mA = 0 mBar and 20 mA = -1000 mBar (vacuum).
[5] unit - Engineering unit
Available:
When a temperature sensor is selected by [1]
SenS parameter.
Range:
°C = Celsius;
°F = Fahrenheit.
[6] FiL - Digital filter on the measured value
Available:
Always.
Range:
oFF (No filter);
0.1 to 20.0 s.
Note:
This is a first order digital filter applied on the
measured value. For this reason it will affect the
measured value but also the control action and the
alarms behaviour.
[7] inE
- Selection of the Sensor Out of Range type
that will enable the safety output value
Available:
Always.
Range: our
=
When an overrange or an underrange is
detected, the power output will be forced to
the value of [8] oPE parameter;
or
=
When an overrange is detected, the power
output will be forced to the value of [8] oPE
parameter;
ur
=
When an underrange is detected, the po-
wer output will be forced to the value of
[8] oPE parameter.
[8] oPE - Safety output value
Available:
Always.
Range:
-100 to 100 % (of the output).
Notes: 1.
When the instrument is programmed with one
control action only (heat or cool), setting a value
outside of the available output range, the instrument
will use Zero.
E.g.
: When heat action only has been programmed,
and oPE is equal to -50% (cooling) the instrument
will use Zero.
2.
When ON/OFF control is programmed and an out
of range is detected, the instrument will perform
the safety output value using a fixed cycle time
equal to 20 seconds.
[9] io4.F - I/O4 function selection
Available:
Always.
Range:
on =
Out4 will be ever ON (used as a transmitter
power supply);
out4 = Used as digital output 4;
dG2.c = Digital input 2 for contact closure;
dG2.U = Digital input 2 driven by 12 to 24 VDC.
Notes: 1.
Setting [9] io4.F = dG2.C or dG2U, the [25] O4F
parameter becomes not visible while [11] diF2
parameter will become visible.
2.
Setting [9] io4F = on the [25] O4F parameter and
the [11]diF2 parameter will NOT be visible.
3.
Setting [9] io4F different from dG2.c or dG2.U,
the instrument will force [13] diF2 parameter
equal to nonE. If [11] diF1 was equal to (SP4 or
UPDN) it will be forced to nonE.
4.
The transfer from [9] io4F = ON to [9] io4F = Out4
will make the [25] O4F parameter visible equal to
nonE.
[10] diF1 - Digital input 1 function
Available:
Always.
Range: oFF
= No function;
1
Alarm Reset [status];
2
Alarm acknowledge (ACK) [status];
3
Hold of the measured value [status]
When the contact is closed the instrument ope-
rates in hold of the measured value;
4
Stand by mode of the instrument [status]
When the contact is closed the instrument oper-
ates in stand by mode;
5
Manual mode
When the contact is closed the instrument ope-
rates in manual mode;
6
HEAt with SP1 and CooL with “SP2” [status]
(see “Note about digital inputs”);
7 to 17
Reserved;
18
Sequential set point selection [transition]
(see “Note about digital inputs”);
19
SP1/SP2 selection [status];
20
Binary selection of the set point made by digital
input 1 (less significant bit) and digital input 2
(most significant bit) [status];
21
Digital input 1 will work in parallel with
but-
ton while digital input 2 will work in parallel with
the
button.
Note:
When [11] diF2 is not available, items 20 and 21 are
not visible.
