RECEPTION
The LC-40 level detectors are supplied individually packed for protection during transport .
On reception of the level detector, check:
− That the float pivots freely in the fork that supports it.
− That the pivot shaft has the two split pins, one on each end.
Important:
If the operation of the limit switches is checked before installation, this must be done in a non
hazardous area.
To check the limit switch, unscrew the electrical housing cover to gain access to the electrical
connections.
Move manually the float from the bottom stop to the top stop of the fork.
The signal at the electrical connection terminals will vary according to the float’s position (with the
AMM and AMR this can be checked using a multimeter).
Once the correct working of the complete system has been checked, mount the level detector as
described below.
MOUNTING
The models designed to be mounted in the side of the tank should be installed in a position so that
the float can move freely in a vertical plane.
The LC-40V y LC-40VR models require installation in the top of the tank.
Important:
Check that the working pressure is not above that specified on the instrument’s identification label.
Check that the ambient and liquid temperatures are within the limits specified on pages 2 & 3.
