8.2 Modify a parameter during
“Operator level”
The instrument is showing the “
Standard display
”.
1.
Press the
button.
2.
The upper display will show the acronym of the first
parameter promoted to this level while the lower display
will show its value.
3.
By
and
button assign to this parameter the
desired value.
4.
Press the
button in order to memorize the new value
and go to the next parameter.
5.
When you want to come back 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 goes back to
the “
Standard display
” and the new value of the last
selected parameter will be lost.
8.3
Entering the “Limited access level”
The instrument is showing the “
Standard display
”.
1.
Press the
button for more than 5 seconds;
2.
The upper display will show
PASS
while the lower display
will show
0
;
3.
By
and
buttons set the value assigned to
[118] PAS2 (Level 2 password).
Notes: 1.
The factory default password for configuration
parameters is equal to 20.
2.
All parameter changes are protected by a time
out. If no button is pressed for more than 10 s the
instrument automatically returns to the “
Standard
display
”, the new value of the last selected
parameter is lost and the change parameter
procedure is closed.
To work with no time out (e.g. for the first
instrument configuration) use a password equal to
1000 plus the programmed password
(e.g. 1000 + 20 [default] = 1020).
It is always possible to manuallyend the
parameter configuration procedure (see below).
3.
During the parameter setting procedure the
instrument continues to perform the control.
In certain conditions (
e.g. when a parameter change
can produce a heavy bump to the process)
it is ad-
visable to temporarily stop the controller from control-
ling during the programming procedure (the control
output will be OFF).
A password equal to 2000 + the
programmed value (e.g. 2000 + 20 = 2020) switches
OFF the control output during configuration. The
control restarts automatically when the parameter
setting procedure will be manually ended.
4.
Push
button.
5.
The instrument will show on the upper display the
acronym of the first parameter promoted to this
level and on the lower one its value.
6.
Using the
/
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.
When you want to return to the “
Standard display
”
push the
button for more than 5 s.
8.4 How to see but not modify the
“limited access parameters”
Sometimes it is necessary to give to the operator the
possibility to see the value assigned to the parameter
promoted in the Limited Access level but it is important that all
changes are made by authorized personnel only.
In this cases, proceed as follows:
1.
Press the
button for more than 5 seconds;
2.
The upper display will show
PASS
while the lower display
shows
0
;
3.
By
and
button set the value
-181
;
4.
Push
button;
5.
The upper display will show the acronym of the first
parameter promoted to level 2 and lower shows its value;
6.
Using
button it is possible to see the value assigned
to all parameters present in level 2 but it will not be
possible to modify it;
7.
It is possible to return to the “
Standard display
” pressing
the
button for more than 3 seconds or by pressing no
buttons for more than 10 seconds.
8.5 Automatic mode
8.5.1 Keyboard functions when the
instrument is in Auto mode
Performs the action programmed by [121] uSrb
(
button function during RUN TIME) parameter.
Enters the parameter modification procedures.
A short pressure (less than 2 seconds) displays the
“additional information” (see below)
a pressure longer than 2 second starts the “Direct set
point modification” function (see below).
Starts the “Direct set point modification” function (see
below).
8.5.2 Direct set point modification
This function allows to quickly modify the set point value
selected by [83] A.SP (selection of the active Set point).
While the instrument is showing the “
Standard display
”:
1.
Push the
or the
button for more than 2 s.
The upper display shows the acronym of the selected set
point (e.g. SP2) and the lower display shows its value.
2.
By
and
buttons, assign to the active set point the
desired value.
3.
To exit, press NO buttons for more than 5 second or
press the
button.
In both cases the instrument stores the new value and
returns to the “
Standard display
”.
Note:
If the selected set point has not been promoted to the
Operator level, the instrument allows you to see the
value but not to modify it.
