or 999.9°F.
2. Every change of the SEnS parameter setting
will force the [2] dP = 0 and it will change all
parameters related with dP (e.g. set points,
proportional band, etc.).
[2] dP - Decimal point position
Available: Always.
Range: When [1] SenS = Linear input: 0... 3.
When [1] SenS different from linear input: 0 or 1.
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... 9999.
Notes: 1. SSc allows the scaling of the analogue 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... 9999
Notes: 1. Fsc allows the scaling of the analogue 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 = Centigrade
°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... 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 = The out 4 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... 24 VDC.
Notes: 1. Setting [9] io4.F = dG2.C o dG2V, the [22] O4F
parameter becomes not visible while [11] diF2
parameter will become visible.
2. Setting [9] io4F = on the [22] 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 [12] 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 =
Out 4 will make the [22] O4F parameter 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 oper-
ates in stand by mode.
5Manual mode
6HEAt with SP1 and CooL with “SP2” [status]
(see “Note about digital inputs”)
7Timer Run/Hold/Reset [transition]
Short closure allows to start timer execution
and to suspend it while a long closure (longer
than 10 seconds) allows to reset the timer.
8Timer Run [transition] a short closure allows to
start timer execution.
9Timer reset [transition] a short closure allows to
reset timer count.
10 Timer run/hold [Status]
- Contact closure = timer RUN
