032 - Flow Max - Main Flow

Figure 173: Warning 032 -FM Main Flow

This alarm appears at the submaster whenever the measured flow

is more than the Main Line Break Limit established at the

submaster. It indicates that the sum of water from all Flow Max

participants exceeds the Main Line Break Limit. The submaster

automatically issues a STOP WATER warning to all

participants, to insure that all irrigation at every satellite

terminates. The NORMALLY OPEN MV terminal will be

automatically energized at the submaster as well as at the shared

location. IMPORTANT: All future scheduled irrigation for any

of the Flow Max participants will not occur until this alarm has

been cleared at the satellite.

"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=620" THEN satellites 01-02, 01-

05 had irrigating stations and the sum of their measured

flow was 620 GPM.

Action:

Step 1 Review the warnings at the listed satellites to

determine which stations were on at the time of the

warning.

Determine if any of these stations were responsible

for the Main Line Limit failure.

Step 2 Inspect the main line as well as major branches for

failure.
