ESP-LXME Controller
E
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 ow 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 ow condition was detected. The
controller will eliminate the high ow condition by closing the
Master Valve to eliminate a mainline problem or closing the
problem valve to eliminate a problem with a station.
B. Shut Down and Alarm instructs the controller to shut down
the Master Valve when a high ow 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.
F
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 ow. Press the
+ and – buttons to set the Low Flow Threshold; then press Next.
Press and HOLD buttons to accelerate settings for percentages.
NOTE: Consider using the default setting of 70% (or lower) for
SEEF Low ow Threshold. Using a higher percentage can result in
false alarms due to normal hydraulic variability.
e f
G
Settling Time is selected, allowing you to set the time limit (from
3-10 minutes) that a station ow 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.
H
The SELF Actions screen appears, allowing you to set the
controller’s behavior when a SELF condition exists.
A. Diagnose and Eliminate allows the controller to determine if the
low ow condition is due to a problem on the mainline (aects all
valves) or downstream of one of the valves that was running when
the low ow condition was detected. The controller will eliminate
the low ow condition by closing the Master Valve to eliminate
a mainline problem or closing the problem valve to eliminate a
problem with a station.
B. Shut Down and Alarm instructs the controller to shut down the
Master Valve when a low ow 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 SELF Action; then press Next.

NOTE: If the selected action for both SEEF and SELF is Alarm
Only, then the system is not disabled and the Delay to Re-Enable
screen will not be shown.
