Potential Cause
Solution
Station
Valves
A station valve is not
operating.
Valve is manually closed or
solenoid is damaged.
Turn dial to Manual Watering and select Start Station.
Select the station making sure it has a run time and
press run. Check to see if the valve is operating and if it
isn’t address the valve issue.
Station does not have run
time for a program with start
days and a start time.
Turn dial to Test All Stations / Check System and select
Station Run Time. Note which programs the station
has run times programmed. Use Program Summary to
make sure that program has start days and start times.
Station
Valves
A station valve is not
operating.
Decoder or valve wires are not
spliced correctly.
Turn dial to Test All Stations / Check System and select
2-Wire Diagnostics. Select Ping Decoders, Station
Decoder and ping the Station Decoder address. If the
ping test fails check the decoder and valve wire splices
and repeat the ping test.
Incorrect Decoder address.
Check the Decoder address of the station (label on
Decoder that is connected to the valve) and verify the
address is entered correctly. Turn dial to Setup Wizards
and select Station Setup to access Station Decoder
Address.
Incorrect Valve Type
Turn Dial to Setup Wizard and select Valve Types. Valve
types configure the decoder inrush amps and duration
for opening a valve solenoid. The ESP-LXD Valve Types
are preconfigured for Rain Bird commercial valve
models. Information for configuring Valve Types to work
with other valves can be found in the controller manual.
Note: Rain Bird residential valves (DV, JTV, HV) are not
compatible with the ESP-LXD system or FD-Series
Decoders.
2-wire path from the
controller is not connected to
this area.
Ping other valves on the same 2-wire path leg. If these
pings are also unsuccessful, check for an open wire
connections on the 2-wire path.
Master
Valves
The Master Valve will not
open when stations are
operating.
MV is assigned to a different
FloZone than the stations.
Turn dial to Setup Wizards and select Master Valves.
Press Next to advance to FloZone (FZ) Setup screen.
MV needs to be assigned to the same FloZone as the
stations that receive water from this water source.
MV is Normally Open but
has been configured as a
Normally Closed MV.
If the MV valve is Normally Open (powered to close)
it needs to be configured as Normally Open. Turn dial
to Setup Wizards, select MV Setup. Change MV from
Normally Closed (default) to Normally Open.
Station not configured to
open Master Valve.
Go to Valve Setup Wizards, Station Setup to make sure
the station is configured as requiring a Master Valve.
MV Decoder address is
incorrect.
Check the Decoder address of the MV (label on Decoder
that is connected to the MV) and verify the address is
entered correctly. Turn dial to Setup Wizards and select
Master Valves to access MV Decoder Address.
