Now click the Modify Run Times button under Station Operations at the right side of the
screen. The Modify Run Times window will open in front of the Auto Programming screen. It
has several options, but for now, note that you can simply enter a time in minutes and hit the
Replace button. All selected slots will have their run time changed simultaneously. The new run
time will replace the old run time for all selected slots. You can also pick the Percent Scale
button to reduce or increase run times of the selected stations by the same percentage. The ET
option will be discussed in Chapter 10.
For example: Select slots 1 through 8 by holding the shift key while clicking 1 and 8. If 3 is
entered in the modifier text box, clicking the Replace button and OK will replace all the run times
of slots 1 through 8 with 3 minutes.
The Renumber Highlighted Stations command allows you to replace the selected station
numbers with 0 or any station number sequence desired. Simply enter the first number in the
sequence and the remaining stations will be numbered sequentially.
NOTE: It is not necessary to reset the station number to 0 to prevent the station from running if
the station runtime is already set to 0, which causes Sentinel to ignore the slot.
For example: Select stations 6 through 10 by holding the shift key while clicking on 6 and 10.
Click Renumber Highlighted Stations and enter 1. Stations 6 through 10 will automatically be
renumbered with 1 through 5.
Modify the run times of the newly
renumbered stations to 5 minutes.
The Search and Highlight command is discussed at the end of Chapter 6: Zone Data, which explains the process of
selecting stations by descriptions entered in the Zone Data screen.
Click Clear Highlights to deselect the five slots and change the station number color back from white to black. If this were
transmitted to the field unit along with a Start Time, station 1 would run for 3 minutes, followed immediately by stations 2
through 5 for 3 minutes each, in order. It will be immediately followed by station 1 again for 5 minutes this time and then
stations 2 through 5 for 5 minutes each. Though more stations are assigned to other slots, they are ignored since they have
zero run times.
You can assign up to eight start times to each program. The program will start at the
earliest start time within the Water Window, and re-start at each additional start time. If
the time between two different starts is less than the total duration of the program, the
boxes will turn red to warn you that a conflict exists and the start time will be ignored.
IMPORTANT: Do not assign the starts such that more than the maximum number of
programs will be scheduled to run simultaneously, as the controller firmware will only
allow up to the maximum station number of outputs that are on at one time. Assigning the
same start time to more than six programs will be displayed properly when you run a flow
graph, but only the first six programs will run. Any remaining programs having the same
start time will not run at all. (This is a hardware limitation.)
The order number of the Start Times is not important. In the first picture above (Water Window set at 8:00 AM to 8:00 AM),
the first program will start at 11:00 PM because it is the earliest start time according to the Water Window. The program will
start again at 1:00 AM and again at 3:00 AM. The Priority order number next to the text boxes do not apply here. These are
used by the Flow Optimizer which is discussed in Chapter 15. If utilizing the Flow Optimizer, ONE AND ONLY ONE start
time must be entered, but the value is not important because the Flow Optimizer will re-assign all start times. In this case, the
Priority number is important. The order of the text field that the start time is entered determines its priority within the entire
system for optimization.
