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.
NOTE:
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 RME Eagle Controller and the valve. This can
be accomplished by manually turning on the valve using the RME Eagle Controller,
see 5.7.2 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.
9.2.5 No Flow Station Fault
The No Flow Station fault occurs whenever a station is activated, which has an established or
learned flow limit and the station measured flow is zero gallons-per-minute. Each time a station
No Flow 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.
Chapter 9 Troubleshooting
If multiple stations are on simultaneously, and the controller detects an
overflow fault, all running stations will be diagnosed as faulty.
