PROGRAM STATE C03
The purpose of this panel is to allow the user to inspect the status and settings of
a particular program. The program number indexes this panel. This panel con-
tains the following information:
Program Number
Reflects the selected program (can be selected only inside panel C 03). See
Section 5.2.
Program State
During the lifetime of a program it cycles through several states. Each
program is initially in NO SET state which means no settings have been
applied to the program by the user. Once the settings have been applied
the program is considered in SET state. Once a specific condition such as
start time is met the program passes to READY state to await execution.
Once the program reaches the highest priority and the start time is met, the
program passes to ACTIVE state and executes. The program may be sus-
pended and placed in WAIT state due to a higher priority program moving
to ACTIVE state or a specific alarm condition triggering. When a program
completes execution it is placed in FINISHED state. The cycle may be
repeated and the program returned to ready state if the program repeats
were specified after a set delay period.
Program Started by
Displays how the last program start was triggered. Programs can be started
by a met time condition, solar radiation level, manual start, low level in
external tank, or directly after the completion of another program. If the
program is in NO SET (no settings applied to program) or in SET (settings
applied but conditions not met) state, “Started by” is blank.
Repeat
Displays the current repetition followed by (/) the maximum number of the
programmed repetitions.
