IVM-SEN/
Sensor
The controller
is not getting
data from
a flow or
weather
sensor
connected to
a IVM-SEN/
Sensor on the
2-wire path.
Sensor wiring
polarity is
reversed.
Many sensor including flow sensors require wires
to be connected with correct polarity (+ / -). If
the sensor has colored or labeled wires, connect
as follows:
• Sensor red (+) wire to the IVM-SEN Sensor
red wire.
• Sensor black (-) wire to the IVM-SEN Sensor
black wire.
Flow sensor
output pulse rate
is not compatible
with the LX-IVM
Controller.
The LX-IVM Controller requires a minimum input
of 2 pulses per 10 seconds for the smallest station
flow rate. Pulse rates of less than 2 pulses per
10 seconds will not be registered. Change to a
compatible flow sensor.
Weather sensor
type is not
compatible.
The LX-IVM Controller is not compatible with 4-20
mA or 0-5V weather sensors (discrete switched
sensors only).
Programs Programs
are running
at random
times.
Multiple start
times have been
programmed
unintentionally.
Turn dial to Diagnostics / Confirm Programs /
Review Program. Review each program using the
Program Button to select the program. Check for
multiple start times on an individual program. In
some cases users’ mix-up start times and stations
and can inadvertently program the system to
start multiple times per day.
Water Windows
have been
configured so
programs are
paused and
resume later.
Turn dial to Delay Watering / Water Window. Use
the Programs Button to select a program 1 - 40.
Water Windows control the hours of the day
a program is allowed to operate. If a program
starts outside a Water Window it is paused until
the window opens. If the program is still running
when the Water Window closes the program is
paused and will automatically start the next time
the window opens. Adjust the Water Window
open and close times to allow the program to
complete.
Station
Sequencing
Stations are
not running
in station
number
sequence
Station
Sequencing set
to Sequence by
Station Priority
The LX-IVM offers 2 station sequencing modes:
• Sequence by Station Numbers (default) – Sta-
tion selection criteria: a) Non-Irrigation Priority;
b) Station number low to high; c) Program
assignment 1 - 40.
• Sequence by Station Priority (automatically
used if FloManager is On) – Station selection
criteria: a) Station Priority Non-Irrigation, High,
Medium, Low; b) Station Run Time longest
to shortest; c) Station number low to high; d)
Program Assignment 1 - 40.
To change Station Sequencing mode turn dial to
2-Wire Settings / Advanced / Station Sequencing.
Use the +/- softkeys to change the selection.
