OPERATION
The level variations in a tank, move the float into the level body.
The float, as it passes by the point where the LT-AMM limit switch is, by means of magnetic
coupling acts on the micro-switch lever changing its position.
The micro-switch position is maintained until the float passes in the opposite direction at the limit
switch position, changing the micro-switch to its original state.

ELECTRICAL CONNECTION
For the electrical installation it is recommended to use multiple conductor cables with individual
cable sections in the order of 0.25 or 0.5 mm

in order to make it easier to connect. Individual
cables should not be used as they will impair the IP-65 rating of the cable gland.
Before starting the installation, check that the cable to be used are the right size for the cable
gland on the connector, this will guarantee the instrument will stay water tight.
Peel the outside insulation to free the inner cables. It is recommended to tin the cables at the
ends of the wires to avoid loose ends which can produce short circuits. Pass the cables through
the cable gland and screw in the cables in their positions. Once the wiring is finished make sure
that the cables are well gripped by the cable gland to maintain the ingress protection degree.
