020 - Flow Max - Flow Upper Limit Violation

Figure 161: Warning 020-FM Flow Upper Limit

This warning appears at the submaster whenever the measured

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

"SAT=" lists the address(es) of any satellites which were

irrigating at the time of the warning.

Example: Assume a submaster address of 01-00. If the warning

reads "SAT=2,5 GPM=420" then satellites 01-02,

01-05 had irrigating stations and the sum of their

measured flow was 420 GPM.

Action:

Step 1 Examine the warnings at the listed satellites to

determine which stations were on at the time of the

warning. Each satellite will have an "FM STATION

ADVANCE" warning. This warning indicates

which stations were on at the time the submaster

detected the "FLOW UP LIM" violation.

Step 2 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 3 IMPORTANT:

Upon resolution of the problem, CLEAR all

warnings at all satellites. If warnings are not

cleared, the stations will remain off indefinitely.
