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 fi lter on the measured value
Available:
Always.
Range:
oFF (No fi lter);
0.1 to 20.0 s.
Note:
This is a fi rst order digital fi lter applied on the
measured value. For this reason it will affect the
measured value but also the control action and the
alarms behaviour.
[7] bS
- PV input bias
Available:
Always.
Range:
In Engineering unit, it is programmable from -100 to
100 % of the input span
[8] di.A - Digital Input Action
Available:
Always.
Range:
0 =
DI1 Direct action,
1 =
DI1 Reverse action,
]
out Group - Output parameters
[9] 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.
[10] o1F - 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;
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;
[11] Ao1L - Initial scale value of the analog
retransmission
Available:
When Out 1 is a present
Range:
-1999 to [12] Ao1H.
[12] Ao1H - Full scale value of the analog
retransmission
Available:
When Out 1 is present
Range:
[11] Ao1L to 9999.
[13] o3F - Out 3 function
Available:
When the instrument has out 3 option.
Range:
nonE = Output not used. With this setting the status
of the this output can be driven directly
from serial link;
AL =
Alarm output;
or.bo = Out-of-range or burn out indicator;
P.FAL = Power failure indicator;
bo.PF = Out-of-range, burn out and Power failure
indicator;
[14] o3AL - Alarms linked up with Out 3
Available:
When [13] o3F = AL.
Range:
0 to 15 with the following rule:
+1 =
Alarm 1;
+2 =
Alarm 2;
+4 =
Sensor break (burn out);
+8 =
Overload on Out 4 (short circuit on out 4);
[15] o3Ac - Out 3 action
Available:
when [13] o3F is different from “nonE”.
Range:
dir =
Direct action;
rEU =
Reverse action;
Notes: 1.
Direct action: the output repeats the status of the
driven element. Example: the output is an alarm
output with direct action. When the alarm is ON,
the relay will be energized (logic output 1).
2.
Reverse action: the output status is the opposite
of the status of the driven element. Example:
the output is an alarm output with reverse
action. When the alarm is OFF, the relay will be
energized (logic output 1). This setting is usually
named “fail-safe” and it is generally used in
dangerous process in order to generate an alarm
when the instrument power supply goes OFF or
the internal watchdog starts.
[16] o4F - Out 4 function
Available:
Always
Range:
nonE = Output not used. With this setting the status
of the this output can be driven directly
from serial link.
AL =
Alarm output;
or.bo = Out-of-range or burn out indicator;
P.FAL = Power failure indicator;
bo.PF = Out-of-range, burn out and Power failure
indicator;
On =
Output ever ON (it is used as auxiliary
power supply for TX).
[17] o4AL - Alarms linked up with Out 4
Available:
When [16] o4F = AL.
Range:
0 to 7 with the following rule.
+1 =
Alarm 1;
+2 =
Alarm 2;
+4 =
Sensor break (burn out);
[18] o4Ac - Out 4 action
Available:
When [16] o4F is different from “nonE”.
Range:
dir =
Direct action;
rEU =
Reverse action;.
