9.2.1 Wiring Fault
The RME EAGLE 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:
•
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: If multiple stations are on simultaneously, and the controller detects an
over current fault, all running stations will be diagnosed as faulty.
NOTE: If a short circuit occurs at the Normally Closed Master Valve and the
program has been SETUP to use a Master Valve. The controller will
successively condemn all remaining stations in the program. Upon
reviewing the fault, all stations of the program shall illuminate, indicating
that the problem appears to be the Master Valve.
User Action:
1. Excessive station current may be due to an inadvertent direct connection between the station
wire and the common wire.
2.
Check for exposed wiring in a flooded valve box.
3. Check for a faulty valve solenoid.
4. When corrective action has been completed, the fault should be cleared.
