COn Group - Consumption parameters
[134] Co.tY - Count type
Available:
Always.
Range:
oFF Not used;
1 Instantaneous power (kW);
2 Consumed energy (kWh);
3 Reserved;
4 Total worked days: number of hours the instru-
ment is turned ON divided by 24;
5 Total worked hours: number of hours that the
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 [137] 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 [137] 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 [137] 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 th-
reshold set in [137] h.Job.
Notes: 1.
Selections 4 to 11 represent an internal count:
these modes calculate the instrument work in
hours or days. When the count reaches the
threshold set with parameter [137] 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 -
parameter [137] 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.

[136] cur - Nominal current of the load
Available:
When [134] Co.tY = ist or
[134] Co.tY = h or
[134] Co.tY = S.S.
Range:
1 to 999 (A).
[137] h.Job - Threshold of the working period
Available:

[134] Co.tY = tot.H.
Range:
oFF = Threshold not used
1 to 9999 days when
[134] Co.tY = 4
;
1 to 9999 hours when

(not resettable)
Available:
Always.
Range:
1 to 9999 days.

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.

[141] A.H.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.
[142] A.H.o - Adjust High Offset
Available:
Always.
Range:
-300 to +300 Engineering Units.
Example:
Environmental chamber with an operative range:
10 to 100°C.
1.
Insert in the chamber a reference sensor connected with
a reference instrument (usually a calibrator).
2.
Start the control of the instrument, and set a set point equal to
the minimum 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 [139] A.L.P = 10 (low working point) and [140]
A.L.o = -1 (it is the difference between the reading of the
instrument and the reading 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
