Summary of Contents for Rain Master RME HAWK

  • Page 2 THIS PAGE INTENTIONALLY LEFT BLANK.
  • Page 3 Your RME HAWK has many high-end features. Features such as accurate, economical flow sensing, and cycle and soak programming are yours at the press of a button. In addition, your new RME HAWK controller maintains full support of independent pump and normally closed or normally open master valves.
  • Page 4 Manually activated station cycle allows you to run a single station for a selected time. • Built-in remote control capability for Rain Master Remotes. • Automatic field wire fault detection enables the controller to sense a short in the field wire and instantly turn off that station, report the fault and move to the next programmed station.
  • Page 5 CONTROLLER ADVANCED FEATURES • Ability to select cycle-and soak programming or conventional programming on a per- program basis. This feature includes: - Ability to set RUNTIME, MAX CYCLE TIME and SOAK time on a per station basis. - Automatic minimization of the water window by intelligently scheduling station starts if and when other stations are satisfying their SOAK TIMES.
  • Page 6 USER PROGRAMMABLE FEATURES (SETUP) The following features can be easily selected or reconfigured by a single push of a button (SETUP key) • Programmable Master Valve allows you to program a Master Valve to go on by program. • Programmable type of Master Valve allows you to select either a Normally Closed Master Valve or a Normally Open Master Valve.
  • Page 7 • Programmable unscheduled flow limit allows you to setup an upper flow limit from 0 to 999 GPM. This limit defines the maximum allowable flow when there is no scheduled irrigation, e.g.. usage of manual quick coupler devices. • Programmable flow check delay allows you to set up a delay after any station changes, from 1 minute to 6 minutes, during which time no flow limits are checked.

  • Page 34 STATIONS (for a conventional program) This is used to select the stations and set the runtime for each station. After entering the desired Station #, the runtime for the station is then entered. Percentage is briefly shown at the beginning to remind you of its setting. Selected stations are shown in the top display.
  • Page 35 QUICK STATIONS (for a conventional program) This is used to rapidly program a block of stations which all have the same runtime. First the lowest station number is entered, then the highest and then the runtime. This length is applied to all the stations from the lowest through the highest. Selected stations are shown in the top display.

FAULT DETECTION OVERVIEW The RME Hawk has the ability to detect and take corrective action for a number of field related failure conditions. The operator is informed of any fault condition when the display alternates with the following words: FAULT..

  • Page 46: Wiring Fault

    Refer to the fault type(s) defined below for specific information. WIRING FAULT The RME HAWK has been equipped to detect station short circuits which may occur due to improper field wiring or faulty valve solenoids. In the event a station draws excessive electrical current, the following action occurs: •...
  • Page 47 • All scheduled start times for future programs will be ignored (no programs will start) • The controller remains in this state until the fault is cleared by you. User Action: 1. Inspect the main line as well as major branches for failure. 2.
  • Page 48 This fault occurs whenever the measured flow is more than the expected flow (upper station limit failure). Each time a station overflow condition is detected the following action occurs: • The offending station will be immediately turned off. • The next scheduled station of the program will be started. •...

  • Page 50 Using this feature allows you to program a master valve to be activated when program 1,2,3 or 4 is activated. If you have your pump connected to the master valve output of the controller then use this feature to activate the pump when program 1,2,3 or 4 is activated. EXAMPLE: You want a pump to go on when Programs 1 and 3 are running.
  • Page 51 Using this feature will allow you to program a Pump to be activated when program 1,2,3, or 4 is activated. The controller uses Station 1 as the pump output. This feature should only be used for the Pump, if it is connected to the Station 1 output of the controller. If the pump is connected to the Master Valve output, then use the MV feature.

  • Page 52: Security Code

    Note: This feature should only be used where security is limited. The RME HAWK controller has the capability to enter a password code which must be entered before any function(s) can be executed. This code can be up to 4 numbers long.
  • Page 53 No stations, however, will water due to the wet condition. The RME HAWK Controller has the ability to affect irrigation based on an external rain sensor or remote switch. This feature can be programmed by individual program so that one or more programs will cease watering as long as the rain sensor is active.
  • Page 54 QUIT ALARM The RME HAWK controller is equipped with an audible alarm feature which notifies the operator if a field wire or flow fault has been detected. The alarm is an audible “chirp” which occurs once every 6 seconds. It remains in effect until the alarm is cleared by you.

For a description of what a cycle and soak program means see the QUICK AND BASIC PROGRAMMING section of this manual under the heading of STATIONS AND WATERING TIMES.
  • Page 56 PIPE In order to properly measure flow, the pipe size of the Rain Master flow sensor must be specified. Appendix A lists flow sensor part numbers versus pipe size. You can select the following pipe sizes in inches: 1, 1.25, 1.5, 2, 3 and 4.
  • Page 57 normally closed master valve, the typical installation should have no flow and the limit should be set to zero. For systems which have a normally open master valve and the possibility of supplemental watering due to quick coupler manual devices, you have the option of setting a non-zero value which shall be allowed when the controller does not have any active stations.
  • Page 58 The total gallons is the total since the last time you cleared it. Note: The total gallons will automatically be cleared when you select a new pipe size (via the Pipe Setup feature). Note: This SETUP function will be skipped if you have not enabled the flow features . EXAMPLE: You wish to determine how many gallons you use in a month.
