In the series of example pictures to the right,
Application Rates were entered in the Zone
Data screen for some stations. This
demonstrates the full potential of the Edit Slot
window introduced in Chapter 5.
Now you can see the description and zone data
for the selected station as you enter the run time.
Moreover, you can enter any one of the top six
variables, and Sentinel will automatically
calculate the other five.
In the Inches / Program text field, 1 (inch) was entered and the software
automatically calculated the Run Time and total Gallons of water. The three
boxes in the top right corner account for additional starts and repeats of the
same program, so they register the total values for a day. The three boxes to
the left only apply to one start with no repeats. A total run time for the day
could be entered in the top right box and it would be divided by the total start
times and repeats to obtain the Run Time for the slot in the box to the left.
The other variables are similarly related.
The Data Ret. (Retrieval) screen, accessed from the Master Control Panel, is
only used for units with a flow meter or alarm attached to the field unit. The
screen is not available if Data Retrieval Installed? is not checked in the Special
Data screen.
On this screen, you can enter and transmit the conversion constants for a flow
meter to the field unit. K is the multiplier to convert clicks per second in a flow
meter to gallons per minute. The Offset is added for adjustment.
If you have a phone modem connected to the field unit’s serial port, you can use
the Sentinel pager option. Turn on Flow Watch and specify the paging for any of
the four alarms on the screen. Station Overflow occurs when the flow in a
station exceeds the maximum specified in Zone Data. Master Shutdown occurs
after three Station Overflow events. Unexpected Flow occurs when a station is
off but the flow meter detects a flow. Minimum Shutdown occurs when the flow
in any running station is less than the value specified in the Minimum Flow box.
The Alarm Input is for your own custom alarm. Select Open if your dry contact switch is normally closed and vice versa. You
can choose Shutdown and specify one or more Clusters of Programs to shut down if an alarm occur. You can also choose
Start and specify one or more Clusters of Programs to start if alarm occurs. Moreover, you can check the Send Page
option if you have a phone modem connected to the field unit’s serial port. With this option enabled, Sentinel will send an
alarm page to the specified pager in Special Data whenever an alarm is activated.
