3 Mounting
Install away from falling
material for easiest
configuration
For solids laser beam can
be aimed at any angle
Also typically applies to other
scattering surfaces such as
slurries and some turbulent
liquids
For typical liquid applications
laser beam must be as
perpendicular as possible,
not exceeding 90° ± 5° to
the surface
4 Easy setup
1 Rotate the housing: unscrew the stop tang-screw by
approximately 1 rotation (do not pull it out) before removing
the housing. When the desired position is reached,
re-tighten the stop tang-screw.
2 Connect the cables (15.5 to 42 V DC) to the LLT100 laser level
transmitter – if using HART the minimum input voltage is
21 V DC.
3 Power on the transmitter.
4 Press the Right arrow key (
