an error message will be shown (for more details about
this group of error messages see "How to check a
program").
During RUN mode the arrows LED ØÙÚ will show the type of
segment (ramp down, soak or ramp up) is in progress.
NOTE 2: when a program starting is required, the ItSP [r.A05]
parameter of the selected program is equal to "ñEAS" (the
program uses the measured value as initial set point) and an
error is detected on the measuring input, the program starts in
WAIT mode (see below), the upper display will flash, the central
display will show "Err", no arrows LED is lit and the FAST and
JUMP functions are disabled.
The program will start only when at least 10 measures has been
made correctly.
ACTIONS AVAILABLE DURING RUNNING MODE
When a program is running it is possible:
1) to modify all the run time parameters (see "Run time
parameter modification" paragraph);
2) 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");
3) to automatically stop the program in progress (WAIT);
4) to abort program in progress (ABORT);
5) to manually and temporarily stop the program execution
(HOLD);
6) to move forward or backward the executing point of the
program 60 time faster than the programmed value (HOLD +
FAST);
7) to jump to the beginning of a segment from where it is
desired to restart the program (HOLD + JUMP).
WAIT
When the measured value is outside the tracking band
programmed for the segment in progress, the instrument
automatically stops the time counting of the segment and it waits
until the measure value is come back in the tracking band. At
this point the time counting restarts.
During the WAIT mode the instrument operates as follows:
1) the upper display is flashing;
2) the instrument continues to control the process using a fixed
set point;
3) the time counting 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 WAIT mode, it is possible:
a) to abort program execution (ABORT);
b) to stop manually and temporarily the program execution
(HOLD).
