[5] unit - Engineering unit
Available:
When a temperature sensor is selected by
[1] SenS parameter.
Range: °c
Centigrade;
°F
Fahrenheit.
m
The instrument scales the measurement (and the
“variables”) but does not touch the value of the
parameters related to the display.
[6] FiL - Digital filter on the measured value
Available: Always.
Range: oFF No filter;
0.1... 20.0 s .
Note: This is a 1
st
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 de-
tected, 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 power output
will be forced to the value of [8] oPE parameter.
[8] oPE - Safetyoutput 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 uses zero.
E.g.
: When heat action only has been programmed,
and oPE is equal to -50% (cooling) the instrument
uses 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] io3.F - I/O3 function selection
Available:
Always.
Range: on
Out3 is maintained in ON status (used as a
transmitter power supply);
out3
Used as digital output 3;
dG2.c
Digital input 2 drven by contact closure;
dG2.U
Digital input 2 driven by 12... 24 VDC.
Notes: 1.
Setting [9] io3.F = dG2.C or dG2.U hiddens
parameter [22] o3F (not visible) while [11] diF2
parameter becomes visible (available).
2. Setting [9] io3F = on hiddens parameters [22] o3F
and [11] diF2.
3. Setting [9] io3F = on or out3 , the instrument forces
[11] diF2 parameter to oFF . At the same time if
[10] diF1 = 20 or 21 it will be forced to oFF .
4. Changing [9] io3F from on to Out3 makes the
[22] O3F parameter visible and 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];
4
Stand by mode of the instrument [status].
When the contact is closed the instrument oper-
ates in stand by mode;
5
Manual mode;
6
HEAt with SP1 and CooL with “SP2” [status]
(see “Note about digital inputs”);
7
Timer Run/Hold/Reset [transition].
A short closure allows to start timer execution
and to suspend it while a long closure (longer
than 10 seconds) allows to reset the timer;
8
Timer Run [transition]. A short closure allows to
start timer execution;
9
Timer reset [transition]. A short closure allows
to reset timer count;
10
Timer run/hold [Status]:
- Contact close = timer RUN;
- Contact open = timer Hold.
11
Timer run/reset [status];
12
Timer run/reset with a special “lock” at the end of
the time count (in order to restart the time count
the instrument must detect a run command com-
ing from serial link keyboard or digital input 2);
13
Program Run [transition].
The first closure allows to start program execu-
tion but a second closure restart the program
execution from the beginning;
14
Program Reset [transition].
A contact closure allows to reset program execution;
15
Program Hold [transition].
The first closure allows to hold program execution
and a second closure continue program execution;
16
Program Run/Hold [status].
When the contact is closed the program is running;
17
Program Run/Reset [status].
- Contact closed - Program run;
- Contact open - Program reset;
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.
Note:
When [11] diF2 is not available, items 20 and 21 are
not visible.
[11] diF2 - Digital input 2 function
Available: When [9] Io3.F = diG2.
Range: oFF No function;
1 Alarm Reset [status];
2 Alarm acknowledge (ACK) [status];
3 Hold of the measured value [status];
4 Stand by mode of the instrument [status].
When the contact is closed the instrument oper-
ates in stand by mode;
5 Manual mode;
