002 - Station Flow Too High

Figure 143: Warning 002-Flow Upper Limit

This warning appears at any controller whenever the measured

flow is more than the expected flow (upper limit failure). The

warning displays the station number (2) which was on at the time

of the upper limit violation, the Master Valve (MV1) and/or

Pump, as well as the GPM reading (90) as measured by the flow

meter. Upon detection of this condition, the controller

automatically terminates irrigation on the station and advances to

the next station in the program. Condemned stations will not

irrigate again until the warning has been cleared.

Action:

Step 1 Check for:

a. Stuck valve (from previous station)

b. Broken pipes/heads

c. Incorrectly established individual station limits

d. Large variations in system water pressure

Step 2 If station limits are suspected, manually turn each

station on and observe the nominal GPM readings.

To manually turn on a station and read the flow,

refer to the Manual Test procedure, (8-2)

Step 3 Compare the GPM reading with the limit setting to

insure that adequate margin exits (typical: 20% over

nominal)
