PREFACE
Thank you for purchasing the Navis tank level monitor. This manual provides information for the best performance and safe application.
This manual does not cover the sensors for which the manuals will come separately.

INTRODUCTION
LW410 models are long-range display units which receive data from NAVIS level sensors, display various level data and use internal
and external alarms for warnings and control of pumps, valves etc. Wi-Fi compatibility (LW410XW/D or LW410XL/D model) allows real-
time data monitoring on “Navis LiveData” web interface. 4-20 mA output (LW410XW/D or LW410XL/D model) allows connection to
external devices. Various level data can be logged to SD card (LW410XL/D model).

MOUNTING
Select the position where the signal reception is strong enough under all conditions. Use remote antenna if necessary.
Display unit can be mounted onto the ferrous surface with four mounting magnets (optional accessories) or with mounting screws (not
included) to any flat surface.
Mounting the display unit with screws:
Unscrew all 4 plastic screws and remove the front panel. Note that the screws can be pulled out only at the correct angle. Place the
rear panel of the display unit to the final mounting position and mark the position for the bores. Remove the casing and drill holes for
the mounting screws. Place the rear panel of the display unit in position and tighten the mounting screws. Attach the front panel of the
display unit with 4 plastic screws. Do not use excessive force to tighten plastic screws.
WIRING
Please note! Switch off the power before connecting the power supply to the display unit.
Unscrew all 4 plastic screws and remove the front panel. Connect the 12-24 V DC power supply. For using external alarm devices,
connect them to the relay connection terminals. For 4-20mA outputs (only on LW410XW/D and LW410XL/D models), connect the
connection terminals to external devices, please note 4-20mA outputs are only available on tank 1 and 2. Place the front panel back
into position and tighten the screws. Switch ON the power supply and check the operation.
