[11] diF2 - Digital input 2 function
Available:
When [9] Io4.F = diG2.
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 ope-
rates 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
Timer 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;
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 the
button while digital input 2 will work in parallel
with the
button.
Notes: 1.
When [10] diF1 or [11] diF2 (e.g. diF1) are equal
to 6 the instrument operates as follows:
•
When the contact is open, the control action is an
heating action and the active set point is SP.
•
When the contact is closed, the control action is
a cooling action and the active set point is SP2.
2.
When [10] diF1 = 20, [11] diF2 setting is forced to
20 and diF2 cannot perform another function.
3.
When [10] diF1 = 20 and [11] diF2 = 20, the set
point selection will be in accordance with the
following table:
Dig In1
Dig. In2
Operative set point
Off
Off
Set point 1
On
Off
Set point 2
Off
On
Set point 3
On
On
Set point 4
4.
When [10] diF1 is equal to 21, [11] diF2 setting
is forced to up.du (21 value) and cannot perform
another function.
5.
When a “Sequential set point selection” is used
(diF1 or diF2 = 18), every closure of of the logic
input increase the value of SPAT (active set point)
of one step. The selection is cyclic:
SP -> SP2 -> SP3 -> SP4.
[12] di.A - Digital Inputs Action
Available:
Always.
Range:
0 =
DI1 Direct action,
DI2 (if configured) Direct action;
1 =
DI1 Reverse action,
DI2 (if configured) Direct action;
2 =
DI1 Direct action,
DI2 (if configured) Reverse action;
3 =
DI1 Reverse action,
DI2 (if configured) Reverse action.

out Group - Output parameters
13] o1.t - Out 1 type
Available:
When the out 1 is a linear output.
Range:
0-20 0 to 20 mA;
4-20 4 to 20 mA;
0-10 0 to 10 V;
2-10 2 to 10 V.
[14] o1.F - Out 1 function
Available:
Always.
Range: •
When the out 1 is a linear output:
nonE = Output not used. With this setting the status
of this output can be driven directly from
serial link;
H.rEG = Heating output;
c.rEG = Cooling output;
r.inP = Measured value Analog retransmission.
r.Err = Analog retransmission of the measured
error (PV-SP);
r.SP = Analog retransmission of the operative set
point;
r.SEr = Analog retransmission of a value coming
from serial link;
•
When the out 1 is a digital output (relay or SSR):
nonE = Output not used. With this setting the status
of this output can be driven directly from
serial link;
H.rEG = Heating output;
c.rEG = Cooling output;
AL =
Alarm output;
t.out = Reserved;
t.HoF = Reserved;
P.End = Reserved;
P.HLd = Reserved;
P. uit = Reserved;
P.run = Reserved;
P.Et1 = Reserved;
P.Et2 = Reserved;
or.bo = Out-of-range or burn out indicator;
P.FAL = Power failure indicator;
bo.PF = Out-of-range, Burnout and Power failure
indicator;
St.By = Stand By status indicator;
diF1 = Repeats the digital input 1 status;
diF2 = Repeats the digital input 2 status;
on =
Out1 always ON;
riSP = Inspection request.
Notes: 1.
When two or more outputs are programmed in the
same way, these outputs will be driven in parallel.
2.
The power failure indicator will be reset when the
instrument detect an alarm reset command by
key, digital input or serial link.
3.
When no control output is programmed, all the
relative alarm (when present) will be forced to
nonE
(not used).
