[5] unit - Engineering unit
Available: When a temperature sensor is selected by
[1] SenS parameter.
Range: °c Celsius;
°F Fahrenheit.

An engineering unit modification does NOT produce
the automatic re-scaling of all parameters related
with the engineering unit (e.g. alarm thresholds,
proportional band, etc.).
[6] FiL - Digital filter on the measured value
Available: Always.
Range: oFF No filter;
0.1... 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

When an underrange is detected, the power
output will be forced to the value of [8] oPE
parameter.
[8] oPE - Safety output value
Available: Always.
Range: -100... 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 the zero value.
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 Out 4 forced to ON (used as a transmitter
power supply);
out4 Used as digital output 4;
dG2.c Digital input 2 for dry contact;
dG2.U Digital input 2 driven by 12... 24 VDC.
Notes: 1. Setting [9] io4.F = dG2.C or dG2V, the parameter
[24] O4F becomes not visible while [11] diF2
parameter becomes visible.
2. Setting [9] io4F = on the [24] O4F parameter and
the [11]diF2 parameter will NOT be visible.
3. Setting [9] io4F different from dG2.c or dG2.U, the
instrument forces [12] diF2 parameter 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
makes parameter [24] O4F visible equal to nonE.
[10] diF1 - Digital input 1 function
Available: Always.
Range: oFF No function;
1Alarm Reset [status];
2Alarm acknowledge (ACK) [status];
3Hold of the measured value [status];
4Stand by mode of the instrument [status].
When the contact is closed the instrument
operates in stand by mode;
5Manual mode;
6Program Run [transition].
The first closure allows to start program
execution but a second closure restart the
program execution from the beginning;
7Program Reset [transition].
A contact closure allows to reset program execution;
8Program Hold [transition].
The first closure allows to hold program execution
and a second closure continue program execution;
9Program Run/Hold [status]. When the contact
is closed the program is running.;
10 Program Run/Reset [status]:
• Contact closed - Program run;
• Contact open - Program reset;
11 SP1/SP2 selection [status];
12 Binary selection of the set point made by digital
input 1 (less significant bit) and digital input 2
(most significant bit) [status];
13 Digital input 1 will work in parallel with but-
ton while digital input 2 will work in parallel with
the button.
[11] diF2 - Digital input 2 function
Available: When [9] Io4.F = diG2.
Range: oFF No function;
1Alarm Reset [status];
2Alarm acknowledge (ACK) [status];
3Hold of the measured value [status];
4Stand by mode of the instrument [status].
When the contact is closed the instrument
operates in stand by mode;
5Manual mode;
6Program Run [transition].
The first closure allows to start program
execution but a second closure restart the
program execution from the beginning;
7Program Reset [transition].
A contact closure allows to reset program execution;
8Program Hold [transition]
The first closure allows to hold program execution
and a second closure continue program execution;
9Program Run/Hold [status]. When the contact
is closed the program is running;
10 Program Run/Reset [status]:
• Contact closed - Program run;
• Contact open - Program reset;
11 SP1/SP2 selection [status];
12 Binary selection of the set point made by digital
input 1 (less significant bit) and digital input 2
(most significant bit) [status];
13 Digital input 1 will work in parallel with the
button while digital input 2 will work in parallel
