ABORT
This function allows to definitively stop the program in progress.
When it is desired to ABORT the program push the RUN
pusbutton and maintain the pressure until the RUN LED will be
turned OFF.
NOTE: the ABORT function can be activated from any condition
(wait, hold, etc..).
After an abort, the instrument comes back in "normal display
mode and in STAND-BY mode using all the parameters (PID
group, action, etc.) programmed for the STAND-BY mode "at
the end of the selected program".
HOLD
This function manually and temporarily stops the program in
progress.
To enable the HOLD mode proceed as follows:
The instrument is in programmer mode and in RUN mode (the
RUN LED is lit).
Push the RUN pushbutton until the HLD LED starts to flash.
When the button has been released, the program stops.
During the HOLD mode the instrument operates as follows:
1) HLD LED is lit;
2) the instrument continues to control the process using a fixed
set point;
3) the time count of the timer events will not be stopped;
4) all standard functions (like alarms, Output failure detection,
etc.. ) are operative.
When the instrument is in HOLD mode, it is possible:
a) to modify all the run time parameters (see "Run time
parameter modification" paragraph);
b) to create or to modify all the programs not running or not part
of the running linked program (see "Simple program
management" and/or "Linked program management");
c) to abort the program execution (ABORT);
d) to move forward or backward the executing point of the
program 60 time fast than the programmed value (HOLD +
FAST);
e) to jump to the beginning of a segment from where it is
desired to restart the program (HOLD + JUMP).
