When the control output is disabled, all the control outputs and
the alarms will go to OFF state and the instrument will operate
as a simple indicator displaying the value measured.
To enable/disable the control output press the
pushbuttons for more than 3 sec. when the instrument is in the
"normal display mode".
The enabling/disabling command is not subject to the
operating parameter protection rule.
During the output power off all the display functions are
available (the display will show "OFF" if the control output value
is required.).
The alarms ( if configured) will not be operative The alarms ( if configured) will not be operative The alarms ( if configured) will not be operative The alarms ( if configured) will not be operative The alarms ( if configured) will not be operative
At power up, the control output will remain disabled if a power
down is occurred.
When the control output is enabled again, all the functions will be
activated as for switching on the instrument.

6.7 Direct modification of the set point

6.7 Direct modification of the set point Direct modification of the set point Direct modification of the set point Direct modification of the set point
When the instrument is in the "normal display mode" and at
least one control output has been configured, modification of
the set point can be accessed directly.
On pressing the or keys for more than 2 s, the set point
will appear (the decimal point to the right of the less significant
figure will be ON) and its value will start to change.
The new set point value will be operating 2 seconds after the
last pressing of the keys. The display will display the value
measured again.

6.8 SMART function

6.8 SMART function 6.8 SMART function 6.8 SMART function 6.8 SMART function
Can automatically optimise the control output. The function has
two algorithms, defined TUNE and ADAPTIVE. The first
calculate the parameters when the process starts. During this
+ FUNC phase, the control output varies from maximum output value
to 0, and vice versa. The instrument can be put in TUNE mode
at any time. The correct parameters are automatically
calculated after there have been two successive peaks.
The ADAPTIVE function is used to re-obtimise the PID
parameters if the process characteristics changes.
The ADAPTIVE algorithm starts automatically after the "TUNE".
If it is not necessary, it is possible to deactivate the smart
function at the end of the TUNE.
To enable/disable the smart function, press the REV key for
more than 3 sec., when the instrument is in the "normal display
mode". The action can be proteced or not (see "P14")
The LED ST will flash during the first phase of the SMART
(TUNE) algorithm, while it will be ON steadily during the
second phase (ADAPTIVE).
When the SMART function is enabled, the control parameters
can be displayed but not modified.

- the SMART function cannot be activated when:
- the ON/OFF check is set (Pb=0);
- the control output is disabled;
- the SMART function has not been configured.
