3. INSTALLATION
1. General
•Remove any obstacles between the sensor and measurement point.
•The bottom of the sensor should be perpendicular to the measurement point.
•Avoid mounting the sensor too close to a wall.
•Avoid setting a maximum level into the Dead Zone range.
•Avoid the exposure to direct sunlight.
•Avoid high voltage or high current lines.
•Install on solid, non-vibrating surface.
•LT260 shall be used in accordance with manufacturer’s specifications.
The bottom of the sensor should be
perpendicular to the surface of water.
When mounting the sensor, keep the distance
to the tank wall into consideration.

5. INITIAL START-UP & DISPLAY
The LT260 has two display modes; a measurement mode for displaying level and a programming
mode for application set-up.
Measure Mode:
In measurement mode, 4 LED’s are seen on the front panel of the LT260, shown below. A
Flashing “0” on the display is shown when it is in fault condition (Lost Echo).
LED Condition Function
Detect & Level Flashing together Indicates Normal Operation
Mode selected = Level
Detect & Distance Flashing together Indicates Normal Operation
Mode selected = Distance
Detect & Space Flashing together Indicates Normal Operation
Mode selected = Space

Flashing alone
Indicates that LT260 is detecting an
echo but checking if the value is
correct.
None All Off
Display indicates “E-Err”
Indicates that LT260 has gone into Fail
condition.
Reasons:
- There is no reflected echo received.
- Transducer and electronic part are
disconnected

6. PROGRAMMING
The “MENU” button is used to enter the programming mode. It is located below the LED
function on the display. In programming mode, a program number is shown on the LCD such as
P01, P02.
Programming Buttons
To enter the Program Mode simply press the “MENU” button >1 sec. Once in Program Mode,
The Level, Distance, and Space LED’s turn off. The software version will display and the Menu
P01 will appear. Use the Up/Down buttons to access each parameter.
