Serial Link; Smart Function - ero electronic LFS User Manual

SERIAL LINK

The device can be connected to a host computer
by a serial link.
The host can put the device in LOCAL (functions
and parameters are controlled via keyboard) or in
REMOTE (functions and parameters are
controlled via serial link) mode.
The REMOTE status is signalled by a LED
labelled REM.
This instrument allows to modify the operative and
configuration parameters, via serial link.
The necessary conditions to implement this
function are the following:
1) Serial parameters from SEr1 to SEr4 should be
properly configurated.
2) Device must be in the OPERATING mode
During the downloading of configuration the
device goes in open loop with all output in OFF
state.
At the end of configuration procedure, the device
performs an automatic reset and then returns to
close loop control.
NOTE: from serial link it is not possible to perform
the "Feedback potentiometer calibration" as well
as the action performed by logic input 2 (Cnt 2).

SMART function

It is used to optimize automatically the control
action.
At instrument power up, if the SMART is ON, the
second algorithm will be enabled.
To enable the SMART function, push the FUNC
pushbutton until "Smrt" parameter is shown.
Pushing s or t set the display "On" and push
the FUNC pushbutton.
The SMRT LED will turn on or flashing according
to the selected algorithm.
When the smart function is enabled, it is possible
to display but not to modify the control parameters
(Pb, ti, td, and rC).
To disable the SMART function, push the FUNC
pushbutton again until "Smrt" parameter is shown.
Pushing s or t set the display "OFF" and push
the FUNC pushbutton. The SMRT LED will turn
off.
The instrument will maintain the actual set of
control parameter and will enabled parameter
modification.
NOTES: 1) When ON/OFF control is pro-
grammed (Pb=0), the SMART
function is disabled.
2) The SMART enabling/disabling can
be protected by safety key (see
P33).
