Flow Max Warnings

019 - Flow Max - Flow Lower Limit Violation

Figure 160: Warning 019-FM Flow Low Limit

This warning appears FM flow lower limit at the submaster

whenever the measured flow is less than the expected flow

(lower 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 35-00.

If the warning reads "SAT=1, 4, 5 GPM=90" then

each of the satellites 35-01, 35-04, 35-05 had one or

more stations which were on. Their combined

measured flow was 90 GPM which is less than the

programmed limit.

Action:

Step 1 Examine the warnings at the listed satellites to

determine which stations were on at the time of the

warning. Stations can be identified by viewing the

"FM STATION ADVANCE" warning at each of the

satellites.

Step 2 Alarm generation may be caused by mis-adjusted

valves, incorrectly established individual station

limits, large variations in static water pressure,

improper regulation, or line impediments.

Step 3 If station limits are suspected, manually turn each

station on and verify the lower limits. To manually
