7 Programming FCM controllers
There are three groups of parameters which allow you to customize the use of the FCM instrument, according to your specific application
requirements:
"C" Parameters or configuration parameters: are to be set at the very beginning, depending on the features of your FCM, its inputs and
outputs.
"P" Parameters or frequently-used parameters: can be frequently modified in order to optimize the performance of the controller
according to changed operating conditions.
Set-point Parameters: can be easily accessed by the end-user without any technical support; they allow you to change the value of the
parameters to be controlled.
At start-up, after the initial waiting step displayed by "---", and during the normal operating mode, the value given to "C33" will be
displayed. (The symbol "---" will appear in the event of current disabling command coming from terminal block).
Main functions of the buttons:
•
: press it to display the unit of measure of the parameter actually being displayed for 1 second .
•
: press it to display the value of the 1st probe; this value is preceded by the corresponding unit of measure, displayed for 1 second
(even if the probe is disconnected).
•
: press it to display the value of the 2nd probe; this value is preceded by the corresponding unit of measure, displayed for 1 second
(even if the probe is disconnected).
•
When an alarm condition occurs, pressing
once will silence the buzzer; if you press it a second time, the alarm signal is
cancelled (provided that the cause that generated the alarm has been removed).
The programming procedure includes three levels of accessibility to the parameters:
−
display and modification of set-point parameters ONLY;
−
display and modification of "P" (frequently-used) parameters, set-points included;
−
display and modification of all parameters: set-point, "P" and "C" parameters.
Note: it is not possible to move from one level to another straightforwardly. To do so you must first bring the current programming
procedure to an end, then enter another programming level
7.1 Setting the set-point ("St" parameters)
1. hold down
(for about 2 seconds) until "St1" appears on the display;
2. when SEL is released, the unit of measure of the set-point is displayed for 1 second; after that the display shows the current value of
the set-point;
3. press
or to change its value (hold down the buttons to quickly increase or decrease the value);
4. press
to confirm the displayed value. If there isn't a second set-point, the programming procedure is over, otherwise "St2" will
be displayed.
5. when
is released, the unit of measure of the set-point is displayed for 1 second; after that the display shows the current value
of the set-point;
6. press
or to change its value (hold down the buttons to quickly increase or decrease the value);
7. press
or
to confirm the displayed value and exit the programming procedure.
7.2 Accessing "P" parameters
1. hold down
(for about 5 seconds) until "P01" appears;
2. press
or to scroll all "P" parameters, set-points included (hold down the buttons to gradually increase the scrolling speed);
3. press
to display the value of the selected parameter (the corresponding unit of measure will be displayed first for 1 second);
4. press
or to change the value of the parameter (hold down the buttons to quickly increase or decrease the value);
5. press
to confirm the displayed value. The identification code of the parameter will appear again on the display.
Note: to display and modify, if necessary, other parameters, repeat steps 2, 3, 4, 5 above.
6.
press
to save any modification and exit the programming procedure.
