Flow Operations
SETUP SCREEN
Press the so key for Setup.
This allows the MainSafe to be named (recommended).
Check the box to enable Monitor Flow.
Assign the P/MV output and Flow Sensor that are assigned to
the MainSafe.
The Flow Zones checks and X’s cannot be set here. They show
the relationship of this MainSafe to the Flow Zones. These are
assigned in the Flow Zones menu, Flow Map screen.
FLOW LIMITS SCREEN
Press the so key for Flow Limits.
MAXIMUM FLOW
Maximum Flow is an absolute high limit for all ow from the
MainSafe level (the water source). If the ow rate exceeds that
amount, irrigation will be shut down. It does not matter what
stations are running or what the learned ow is.
This should be considerably larger than the maximum ow
allowed in normal irrigation in all downstream Flow Zones
(so that it does not alarm before station-level and Flow Zone
diagnostics can be performed).
UNSCHEDULED FLOW
Unscheduled Flow is any ow that is detected by the ow
sensor when no stations are running. A ow rate can be
entered here to permit manual watering up to the specied
amount, without causing an alarm or shutting o the water. If
unscheduled ow is detected over that amount, an alarm will
occur.
ALARM DELAY
High ows will alarm immediately if this is set to None, or
they will be ignored until they have lasted as long as the
time entered here. Set in M:SS format; the longest delay is
9 minutes, 59 seconds. This can eliminate false alarms from
temporary surges in ow.
ALARM CLEAR DELAY
This sets the amount of time a MainSafe zone will remain shut
down before allowing new automatic irrigation attempts. Set
in HH:MM format, the longest delay setting is 23 hours, 59
minutes.
If Alarm Clear Delay is set to Manual Only, automatic
irrigation will never resume aer a high ow or unscheduled
ow alarm, until it is manually cleared by an operator at the
controller. The operator must dial to the Flow menu, select
Clear Flow Alarms, the Flow Alarms that should be cleared,
and click Clear Selected.
