9.2.1 Wiring Fault
The Rain Master 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.
If multiple stations are on simultaneously, and the controller detects an over current
fault, all running stations will be diagnosed as faulty.
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.
9.2.2 Main Flow Limit Fault
The Main Line flow limit, for the controller, has been exceeded.
• 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 this 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. Inspect the main line as well as major branches for failure.
2. Examine the main line limits to ensure they have been correctly established. If the controller
has been setup for NO STACK operation, multiple stations may be on at the same time. The
main line limit should be larger than the sum of the flow totals of all simultaneously “on”
stations.
3. When corrective action has been completed, the fault should be cleared.
