The upper display shows the acronym of the parameter
while the lower display its current promotion level.
The promotion level is defined by a message.
The possible values are:
conF
: The parameter is
NOT
promoted and is
present only in configuration.
In this case the number is forced to zero.
ASS
:
The parameter has been promoted to the
limited access level.
The number indicates the position in the limited
access list.
oper
: The parameter has been promoted to the
Operator level.
The number indicates the position in the limited
access list.
8.
By
and
buttons assign to this parameter the
desired level.
9.
Select the second parameter that you want to add to the
assistance level and repeat step 6, 7 and 8.
10.
Repeat step 5, 6, 7, 8 until the list has been completed.
11.
When you need to exit from promotion procedure, push
button and maintain the pressure for more than 10 s.
The instrument returns back to the “standard display”.
Example:
In the previous example, I have set for SP1 a
promotion value equal to
ASS
.
If now I set for SP1 a promotion value equal to
oPEr
, the
Limited Access list and the Operator list become.

7 OPERATIVE MODES
As we said at paragraph 5.1, when the instrument is
powered, it starts immediately working in accordance to the
stored parameter value.
In other words, the instrument has one status only, the “run
time” status.
During “run time” we can force the instrument to operate
in three different modes: Automatic mode, Manual mode or
Stand by mode:
–
In
Automatic mode
the instrument drives automatically
the control output according to the parameter value set
and the set point/measured value.
–
In
Manual mode
the upper display shows the measured
value while the lower display shows the power output, the
MAN LED is ON and the instrument allows to set manually
the control output power.
No Automatic action will be made.
–
In
Stand by
mode the instrument operates as an indicator.
It shows on the upper display the measured value and on
the lower display the set point alternately to the “St.bY”
message and forces the control outputs to zero.
As we have seen, it is always possible to modify the value
assigned to a parameter independently from the operative
mode selected.
7.1 Modify a parameter during
“Operator level”
Preliminary note
: The parameters available at operator
level (but also at limited access level) are divided into
two parameter “families”: Standard parameters (
par
)and
programs parameters(
prog
).
The standard parameters family is a list and includes the
parameters usually present in a standard controller (e.g. Set
point, alarm threshold, Proportional band, etc..).
Programs parameters are divided into groups (PrG, Pr1, Pr2,
Pr3 and Pr4). The first one (PrG) includes the parameters
necessary to manage the program running (or to select the
program to run), while the other includes all editing parameters
related with a specific program (Pr1 for program 1, etc.).
When the operator desires to edit a parameter, the
instrument asks to select the “family” to be displayed (
UiS
)
and then to choose the parameter.
The instrument is showing the “standard display”.
1.
Press the
button.
2.
The upper display shows
UiS
while the lower displays
par
.
3.
By
and
buttons select
par
.
4.
Press the
button.
5.
The upper display shows the acronym of the first
parameter promoted to this level while the lower display
shows its value.
6.
By
and
buttons assign to this parameter the
desired value.
7.
Press the
button in order to store the new value and
go to the next parameter.
8.
To return to the “standard display” push the
button for
more than 5 seconds.
Note:
The parameter modification of the Operator level
is subject to a time out. If no button is pressed for
more than 10 seconds, the instrument returns to
the “standard display” and the new value of the last
selected parameter will be lost.
