runtime adjustment source
The type of value used to adjust a schedule’s runtime,
such as ET or water budget.
satellite
A controller in the field that is capable of
communicating with the CCU.
satellite data path
The two-wire or wireless radio link path by which
data is transferred from the CCU to the field devices.
schedule
A clock, calendar, and condition sensitive program in
the Maxicom
2
system used to control or monitor
irrigation, lighting, and types of equipment. A
schedule may be linked to other schedules or it may
stand alone. A schedule that controls the operation of
all other schedules at the CCU is called the Master
Schedule.
schedule linking
A procedure that allows the user to tie schedules
together and control the order in which they occur.
SEEF (search and eliminate excessive flow)
A feature that monitors the gallons per minute of flow
in a flo-zone and automatically takes action if
excessive flow is detected. You can define a
percentage of flow that Maxicom
2
will react to and an
amount of time before action is taken.
sensitize
To become sensitive to a certain condition. For
example, an ET-sensitized schedule is programmed to
be sensitive to current ET and will adjust the schedule
appropriately.
sensor
A field device that monitors an area and reports
current conditions back to the CCU. Flow sensors,
soil moisture sensors, wind sensors, weather stations,
and rain sensors are a few of the many types of sensor
options available in Maxicom
2
.
sensor decoder
A field device used to interface moisture sensors and
other dry contact switch closure sensors to the CCU.
site
A single geographical irrigation area that is controlled
by a single controller device such as a CCU.
site rain counter
A rainfall data weather source directly connected to
the CCU.
soil infiltration rate
A measure of how rapidly a particular soil type
accepts water. Soil infiltration rate is used to
determine maximum hourly flow rate and cycle and
soak times.
soil moisture holding capacity
The amount of water the soil can hold before it is
totally saturated. This is a function of the soil type,
root zone depth, and slope.
solar radiation
A source of energy used in the evaporation of water
from the soil and in plant transpiration. It is
measured in terms of its intensity and duration.
station
Irrigation valve, sensor, or switch operated device.
telephone modem
See modem.
template
A partially completed setup for a schedule.
time window
Designated hours between which watering may take
place.
