EDIT.
In this mode it is possible to select and/or to create a program
and to visualize and/or to modify all data of a program.
When the instrument is in EDIT mode, by the RUN pushbutton it
is possible to start the selected program execution.
NOTES: the EDIT mode can be activated from:
1) STAND-BY mode, in this situation the instrument continues
to operate as in STAND-BY mode and no time out is applied
to the group P parameter modification;
2) RUN mode, in this situation the instrument continues to
operate as in RUN mode but a 10 s (or 30 s) time out is
applied to the group P parameter modification and the
running program cannot be modified.
MANUAL.
In this mode the user can set, manually, the control output
percentage or the valve position.
The upper display shows the measured value, the middle
display shows "ñ." followed by the main power output value and
the lower display shows "S." followed by the secondary power
output value (for more details see the "MANUAL MODE"
paragraph).
The MANUAL mode can be activated:
- manually when the instrument is in STAND-BY mode or
- automatically at the end of a program execution (if pro-
grammed).
RUN.
In this mode the instrument operates as programmer with its set
point generated according to the selected pattern. The program
can be started/stopped by the RUN pushbutton or by an external
logic signal.
RUN indicator is lit.
In this mode all data of the running program can be visualized,
but they cannot be modified. Furthermore, the relevant control
parameters (PB, TI, etc.) can be visualized and modified.
WAIT.
This function temporarily stops a running program whenever the
difference between the measured variable and generated set
point exceeds the selected tracking band.
The displayed measured value is flashing.
When the above difference reverts within the preset band, the
WAIT function is automatically deactivated and the instrument
reverts to the RUN mode.
