DX2 Evolution™

Hardware Features

The irrigation central control system shall be the OASIS Central System as Manufactured by Rain Master Irrigation Systems, Inc.

Programming Features

The OASIS Central System shall allow for the programming of each Evolution DX2 satellite controller. Each controller shall have twelve programs. Programs may be either irrigation or non-irrigation. Non-irrigation programs shall be for lighting, security, etc. Non-irrigation programs are independent of rain, freeze and wind shutdown modes.

Each program shall have the following setup options:

1. Specified start times (1-8) or a continuous cycle.
2. Hour/minute or minute/second runtime format.
3. Irrigation program, yes or no.
4. Omit by date effect, on or off.
5. Overlap protection, on or off.
6. Over water limit, give warning or stop water.
7. Inter-station time delay (0-255 sec).
8. Either of two normally closed master valves, or one normally open master valve.
9. Master valve time delay (0-600 sec).
10. Pump operation, on or off.

Each program shall have three options for setting water days. Programmed days can use a 14-day calendar, a 31-day calendar or a Skip by Day schedule. All options shall allow for up to eight start times per program.

The central system shall allow for the programming of up to forty-eight stations per Evolution DX2 satellite controller. Stations may be assigned to more than one program. Station runtimes may range from 1 second to 24 hours. A "Quick Station" function shall allow for the programming of a block of stations all with the same runtime.

Each program shall have a percentage adjustment feature (water budget). This feature shall allow all station runtimes within a program to be adjusted from 0 and 999% of their programmed runtimes that are defaulted at 100%.

The central system shall provide an automated ET (EvapoTranspiration) driven water management capability utilizing user-defined base watering schedules. ET data for this function may be obtained automatically from a Rain Master Weather Center or entered manually by the user. An option is available to automatically obtain the ET data from a CIMIS Weather Center. A global ET percentage adjustment feature (0 - 999%) allows the user to make corrections for site differences.

The central system shall allow the user to enter base schedules and establish a reference ET from which all calculations are derived. On a daily basis, the software will automatically adjust run times for all stations dependent upon daily ET.

The central system includes a "View All" function. This feature shall allow the user to review all programmed data within an Evolution DX2 satellite controller on a single screen. Following are the View All options:

1. Start time - Shows all eight start times for all twelve programs.
2. Stations - Shows all station run times, (up to 48 stations), across all twelve programs.
3. Runtimes/% - Shows adjusted ET program runtimes and program percentages, for all twelve programs.
4. MV - Shows operations of master valve and pump, for all twelve programs.
5. End times - The end time utility calculates and displays all program start and end times for all Evolution DX2 satellites in a system considering adjusted ET station runtimes, program percent, inter-station delay, and global ET percent.

The central system shall provide the capability to upload and download programs between the central computer and the Evolution DX2 satellite controllers. Programs may be automatically downloaded at times set by the user. Programs may be downloaded by type: all valid programs, all modified programs, or all programs. Programs may be uploaded and downloaded manually at anytime. The central system shall support programming changes in the field or at central. If a field change is made, the central user shall be notified via an alarm notification. The central user has the ability to view, modify, and/or reject, any field change(s) before acceptance into the central system database.

The central system includes a "Global Search" function for Conventional and Basic ET programs. The global search feature will display a list of stations based on user defined parameters. Once this list is created, stations may be programmed singularly, in selected combinations, or as a block (multiple stations, Evolution DX2 satellites or programs). Following are the global search options:

1. Irrigation Modes - Basic ET or No ET.
2. Station run times - Hours/Minutes, Minutes/Seconds or Adjust runtime by percentage (1 - 199%).
3. Water days - (14 day schedule only).
4. Program percentage - (1 - 999%).
5. Start times - Add or remove up to 8 start times.

The central system shall allow the user to verify the validity of programs and microclimate assignments. The "Validator" feature will display the results of a user defined search based upon key programming parameters for Conventional and Basic ET programs, as well as, key microclimate assignment information for ET, rain and wind. Optional search parameters are available for Advanced ET and AIM programs. All Validator alert notifications are reported as programming alarms. The central system shall provide the user with two validation modes, manual or automatic. When automatic validation is selected, validity checks are performed once a day per user selected parameters. Following are the Validator search options:

1. No valid programs.
2. Partial programs.
3. Non-irrigation programs.
4. Stations in multiple programs.
5. Stations not at 100%.
6. All programs with 0 percent.
7. Continuous cycle.
8. MM:SS time scale.
9. Omit by date disable.
10. Overlap protection off.
11. Over water limit stop.
12. ET controller assignments.
13. Rain controller assignments.
14. Wind controller assignments.

Communications

The OASIS Central System shall utilize two-way communication throughout the entire system. Data transmissions shall utilize appropriate protocols to insure reliable error-free communications.

The central system shall support serial port expansion to accommodate singular, combined, and repeater communication modes. Available communication options are hardwire, telephone modem, UHF Narrow Band FM radio, trunk radio, store and forward UHF FM radio, wireless cellular and interface to an Ethernet Area Network.

The central system shall provide built-in software for verifying communication path performance and troubleshooting.

The system shall be capable of uninterrupted Evolution DX2 satellite operation in the event that the central computer is not operational or communication failure with one or more Evolution DX2 satellites has occurred.
 

Weather Center

The central system shall utilize OASIS Weather Centers for rain, wind, and EvapoTranspiration data. EvapoTranspiration (ET) data shall be generated from a Weather Computer and rain data shall be stored indefinitely in the central system database.

The central system shall support up to 20 independent microclimates (for rain, wind, and ET) to accommodate Evolution DX2 satellites in different geographic areas to be managed from the central computer.

The central system shall allow for automatic rain shutdown of irrigation program schedules on a per microclimate basis when a specified rate (inches/hour) and/or a daily amount (inches/day) have been measured. The central user shall have two methods for rain restart, manual or semi automatic. In manual mode the Evolution DX2 satellite(s) will remain in rain shutdown until the central operator removes the rain shutdown. In semi automatic mode the central system will automatically remove the Evolution DX2 satellite(s) from rain shutdown after a user specified number of days.

The central system shall allow for automatic freeze shutdown and restart of irrigation program schedules on a per microclimate basis in response to a freeze sensing device. The freeze shutdown option shall be a subset of the rain shutdown option. Rain shutdown functions shall have priority over freeze shutdown functions.
