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.
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.
