9.2.3 Flow Unscheduled Fault
The Unscheduled Flow limit has been exceeded. The controller tests for unscheduled flow
whenever the controller is not performing any irrigation. With no programs running and a
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 is allowed when the controller does not have any active stations. If this value is exceeded the
unscheduled flow fault occurs.
• All running programs are terminated.
• FAULT…PRESS…REVIEW…will appear in the display.
• If the master valve for the controller has been setup as a Normally Open (NO) Master Valve,
then the terminal will be energized with 24 VAC (Master Valve will be closed).
• 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. The user should check for leaks, broken pipe(s), or physical damage.
2. Check the system for any stuck valves from a previous scheduled irrigation cycle.
3. Check that the Unscheduled Flow limit has been properly established. If quick coupling
devices were on at the time the alarm occurred, ensure that there are enough margins for the
unscheduled flow limit.
4. When corrective action has been completed, the fault should be cleared.
9.2.4 Flow Station Fault
The Flow Station 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.
• FAULT…PRESS…REVIEW…will appear in the display.
• The controller will continue to execute programs; however, any faulted station(s) will not be
turned on again.
If multiple stations are on simultaneously, and the controller detects an overflow fault,
all running stations will be diagnosed as faulty.
User Action :
1. Check for:
a. An improperly adjusted valve, this is a valve which does not come on even if 24 VAC is applied.
b. Check the field wiring between the Rain Master Eagle Controller and the valve. This can be
accomplished by manually turning on the valve using the Rain Master Eagle Controller, see 572
MANUAL Station and measuring 24 VAC directly at the valve.
c. If all stations generate a “NO FLOW” alarm condition check the following:
• Flow sensor wiring and setup.
• Proper operation of the Master Valve and/or Pump.
• The main water supply for the system.
When corrective action has been completed, the fault should be cleared by you.
