INSTRUCTION MANUAL
1 - INSTRUMENT DESCRIPTION
1 - Key P : This is used to access the programming parameters and
to confirm selection.
2 - Key DOWN : This is used to decrease the values to be set and to
select the parameters. If the key is held down, the user returns to the
previous programming level until he exits the programming mode.
Outside the programming mode it permits visualisation of the current
measured by the TAHB input.
3 - Key UP : This is used to increase the values to be set and to
select the parameters. If the key is held down, the user returns to the
previous programming level until he exits the programming mode.
Outside the programming mode it permits visualisation of the output
control power.
4 - Key T : This is a key with a function programmable by par.
"USrb". It can be set to : Activate Auto-tuning and Self-tuning
functions, swap the instrument to manual control, silence the alarm,
change the active Set Point, deactivate control.
5 - Led OUT1 : indicates the state of output OUT1
6 - Led OUT2 : indicates the state of output OUT2
7 - Led SET : when flashing, it indicates access to the programming
mode.
8 - Led AT/ST : indicates that the Self-tuning function is activated
(light on) or that Auto-tuning (flashing ) is in progress.
9 - Led – Shift index: indicates that the process value is lower than
the one programmed on par. "AdE".
10 - Led = Shift index: indicates that the process value is within the
range [SP+AdE ... SP-AdE]
11 - Led + Shift index: indicates that the process value is higher
than the one set on par. "AdE".

2 - PROGRAMMING
2 .1 - FAST PROGRAMMING OF THE SET POINT
This procedure permits rapid programming of the active Set Point
and possibly the alarm thresholds (see par 2.3)
Push key "P", then release it and the display will visualise "SP n"
(where n is the number of the Set Point active at that moment)
alternatively to the programmed value.
To modify the value, press "UP" key to increase it or the "DOWN"
key to decrease it.
These keys change the value one digit at a time but if they are
pressed for more than one second, the value increases or decreases
rapidly and, after two seconds in the same condition, the changing
speed increases in order to allow the desired value to be reached
rapidly.
Once the desired value has been reached, by pushing key P it is
possible to exit by the fast programming mode or it is possible to
visualise the alarm thresholds (see par. 2.3).
To exit the fast Set programming it is necessary to push key P, after
the visualisation of the last Set Point, or alternatively, if no key is
pressed for approx. 15 seconds, the display will return to normal
functioning automatically.
2.2 - SELECTION OF THE CONTROL STATE AND PARAMETER
PROGRAMMING
By pushing key "P" and holding it down for approx. 2 sec. it is
possible to enter into the main selection menu.
Using the "UP" or DOWN" keys, it is then possible to roll over the
selections:
to enter into the operating parameters menu
"OPEr"
to enter into the configuration parameters menu
"ConF"
To enter the menu "OPEr", select the option "OPEr" and press the
key "P".
The display will now show the code identifying the first group of
]
parameters (" SP ") and by pressing the "UP" and "DOWN" keys it
will be possible to select the group of parameters to be modified.
Once the desired group of parameters has been selected, the code
identifying the first parameter of the selected group will be visualised
by pushing the "P" key.
Again using the "UP" and "DOWN" keys, it is possible to select the
desired parameter and, if the key "P" is pressed, the display will
alternatively show the parameter's code and its programming value,
which can be modified by using the "UP" or "DOWN" keys.
Once the desired value has been programmed, push key "P" once
more: the new value will be memorised and the display will show
only the code of the selected parameter.
By using the "UP" or "DOWN" keys, it is then possible to select a
new parameter (if present) and modify it as described above.
To select another group of parameters, keep the "UP" or "DOWN"
key pressed for approx. 2 sec., afterwards the display will return to
visualise the code of the group of parameters.
Release the key and by using the "UP" and "DOWN" keys, it will be
possible to select a new group (if present).
To exit the programming mode, no key should be pressed for
approx. 20 seconds, or keep the "UP" or "DOWN" pressed until exit
from the programming mode is obtained.
To enter the menu "ConF" a PASSWORD is required.
At this request, enter, using keys "UP" and "DOWN", the number 381
and push key "P".
If an incorrect password is entered, the instrument returns to the
previous control state.
If the password is correct, the display will visualise the code
identifying the first group of parameters ("
and "DOWN" it will be possible to select the desired group of
parameters
The programming and exit modes for the "ConF" menu are the same
as those described for menu "OPEr".
