(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
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 [140] AH.P = 100 (low working point) and [141] AHo = +2
(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.

The most important step of the configuration procedure is
completed.
In order to exit from configuration parameter procedure,
proceed as follows:
•
Push
button.
•
Push
button for more than 10 s. The instru-
ment will come back to the “standard display”.
5. PARAMETER PROMOTION
Another important step of the instrument configuration is due
to the possibility to create a custom HMI (interface) in order
to make the instrument easy to use for the operator and
comfortable for the assistance.
By a special procedure, named promotion, the OEM can
create two parameter subsets.
The first one is the “limited access” level. This subset is protected
by the password programmed by [117] PAS2 parameter.
The last subset is the “Operator” set (Level1). This level is
NOT password protected.
Notes: 1.
The “limited access” parameter are collected in a list.
2.
The sequence of the “limited access” parameters
is programmable and can be made according to
your needs.
3.
The parameter sequence of the operator level is
the same programmed for “limited access” level
but only specified parameters can be displayed
and modified. This set must be create according
to your requirements.
5.1 PARAMETER PROMOTION PROCEDuRE
The limited access parameter set is a list, so that, before to
start promotion procedure, we suggest to operate as follows:
1. Prepare the exact parameter list you want to make
accessible for limited access.
2. Number the desired parameters in the same sequence
you want to have in the limited access.
3. Define which of the selected parameter will be available
in Operator level also.
Example:
I would like to obtain the following limited access list:
•
OPEr - Operative mode selection
•
SP - first set point
•
SP2 - Second set point
•
A.SP - Set point selection
•
AL1 - Alarm 1 threshold
•
AL2 - Alarm 2 threshold
•
Pb - Proportional band
•
ti - Integral time
•
td - Derivative time
•
Aut.r - Manual start of the auto-tune
But I want that the operator to be able to change: the
operative mode, the SP value and the AL1 value. In this
case the promotion will be the following:

Now, proceed as follows:
1. Push the
button for more than 3 seconds.
2. The upper display will show
PASS
while the lower display
will show
0
.
3. By
and
buttons set a password equal to
-81
.
4. Push
button.
The instrument will show the acronym of the first
configuration parameter group “
]
inP
”
.
5. By
button select the group of the first parameter of
your list.
6. By
button select the first parameter of your list
7. The upper display will show the acronym of the parameter
while the lower display will show his current promotion level.
The promotion level is defined by a letter followed by a
number.
The letter can be:
c
: It shows that this parameter is
NOT
promoted
and it is present only in configuration.
In this case the number is forced to zero.
A
: It shows that this parameter has been promoted
to the limited access level.
The number will show the position in the limited
access list.
o
: It shows that the parameter has been promoted
to the Operator level.
The number will show the position in the limited
access list.
8. By
and
buttons assign to this parameter the
desired position.
Note:
Setting a value different from 0 the letter
c
will change
automatically to
A
and the parameter is automatically
promoted to the limited access level.
9. In order to modify the level from limited access
to operator and vice versa, push
button and,
maintaining the pressure, push
button.
