ESPLXD-ET Controller
F
The SEEF Actions screen appears, allowing you to set the
controller’s behavior when a SEEF condition exists.
A.
Diagnose and Eliminate allows the controller to determine if
the high flow condition is due to a problem on the mainline
(broken pipe, stuck valve, etc) or downstream of one of the valves
that was running when the high flow condition was detected.
The controller will eliminate the high flow condition by closing
the FloZone master valve(s) to eliminate a mainline problem or
closing the problem valve to eliminate a problem with a station.

NOTE:
If you choose the Diagnose and Eliminate action, be aware
that all FloZones, stations and hardware, including FloZones
unaffected by a SEEF or SELF and non-irrigation hardware, may be
temporarily shut down during the SEEF or SELF diagnostic process.
For this reason, if uninterrupted operation of non-irrigation
hardware, even during a SEEF or SELF diagnostic procedure,
is critical for your installation we recommend operating non-
irrigation hardware with latching relays or selecting a SEEF and
SELF Action other than Diagnose and Eliminate.
B.
Shut Down and Alarm instructs the controller to shut down
the master valve(s) on the FloZone when a high flow condition
is detected. The controller will not attempt to diagnose if the
problem is on the mainline or downstream of a valve.
C.
Alarm Only allows the controller to issue an alarm condition, but
take no other action.
Press the + and – buttons to set the SEEF Action; then press Next.

The SELF Settings screen appears with low flow threshold
selected, allowing you to set the bottom limit (between 1-95%)
that a station must achieve to be considered low flow. Press the +
and – buttons to set the low flow threshold; then press Next.
b
l
Press and HOLD buttons to accelerate settings for percentages.

NOTE:
Consider using the default setting of 70% (or lower) for
SEEF low flow threshold. Using a higher percentage can result in
false alarms due to normal hydraulic variability.
H
Settling Time is selected, allowing you to set the time limit (from
1-10 minutes) that a station flow rate must remain at (or below)
the threshold before the controller will issue an alarm or take
action. Press the + and – buttons to set the Settling Time; then
press Next.

NOTE:
If you are using Cycle+Soak, be sure to set your SEEF
and SELF settling times shorter than the cycle portion of your
Cycle+Soak station runtimes. A SEEF or SELF condition can not be
detected if the SEEF and SELF settling times are equal to or longer
than station cycle times.
