instrument is turned ON.
6
Total worked days with threshold: Number of
hours the instrument is turned ON divided by 24,
the controller is forced in stand-by when Co.ty
value reaches the threshold set in [135] h.Job.
7
Total worked hours with threshold: number of
hours that the instrument is turned ON, the
controller is forced in stand-by when Co.ty value
reaches the threshold set in [135] h.Job.
8
Totalizer of control relay worked days: Number
of hours the control relay has been in ON condi-
tion, divided by 24.
9
Totalizer of control relay worked hours: Number of
hours the control relay has been in ON condition.
10
Totalizer of control relay worked days with
threshold: Number of hours the control relay
has been in ON condition divided by 24, the
controller is forced in stand-by when Co.ty value
reaches the threshold set in [135] h.Job.
11
Totalizer of control relay worked hours with
threshold: Number of hours the control relay
has been in ON condition, the controller is
forced in stand-by when Co.ty value reaches
the threshold set in [135] h.Job.
Notes: 1.
When the control action is made using the linear
output or the servomotor, the valid counting
methods are 4, 5, 6, 7.
2.
Selections 4... 11 represent an internal count:
these modes calculate the instrument work in
hours or days. When the count reaches the
threshold set with parameter [135] h.Job the
display shows “r.iSP” (Inspection Requested).
The count reset (with r.iSP cancellation) can be
done only by changing the threshold value - pa-
rameter [135] h.Job. Using counting methods 6, 7,
10, 11, the count reset causes the controller to exit
the stand-by status returning to the control status.

CAL group - User calibration group
This function allows to calibrate the complete measuring
chain and to compensate the errors due to:
–
Sensor location;
–
Sensor class (sensor errors);
–
Instrument accuracy.
[137] AL.P - Adjust Low Point
Available:
Always.
Range:
From
-1999
to
(AH.P - 10)
engineering units.
Note:
The minimum difference between AL.P and AH.P is
equal to 10 Engineering Units.
[138] AL.o - Adjust Low Offset
Available:
Always.
Range: -300... +300
engineering units.
[139] AH.P - Adjust High Point
Available:
Always.
Range:
From
(AL.P + 10)
to
9999
engineering units.
Note:
The minimum difference between AL.P and AH.P is
equal to 10 Engineering Units.
[140] AH.o - Adjust High Offset
Available:
Always.
Range: -300... +300
Engineering Units.
Example:
Environmental chamber with an operative range:
10... 100°C.
1.
Insert in the chamber a reference sensor connected with
a reference instrument (usually a calibrator).
2.
Power ON the instrument and insert a Set Point equal to
the min. value of the operative range (e.g.: 10°C). When
the temperature in the chamber is steady, take note of the
temperature measured by the reference system (e.g.: 9°C).
3.
Set [137] AL.P = 10 (low working point) and [138] ALo = -1
(the difference between the reading of the instrument
and the one of the reference system). Note that after this
set the measured value of the instrument is equal to the
measured value of the reference system.
4.
Set a Set Point equal to the maximum value of the
operative range (e.g. 100°C). When the temperature
in the chamber is steady, take note of the temperature
measured by the reference system (e.g. 98°C).
5.
Set [139] AH.P = 100 (low working point) and [140] AHo = +2
(the difference between the reading of the instrument
and the one of the reference system). Note that after this
set the measured value of the instrument is equal to the
measured value of the reference system.
AH.P = 100°C
AH.o = 2
AL.o = -1
AH.P = 10°C

5.7 Exiting the configuration level
The most important configuration step is completed.
In order to exit from configuration parameter procedure,
proceed as follows:
•
Push
button.
•
Push
button for more than 10 s.
The instrument returns to the “Standard display”.
