12.3.2 LTL models
To fix the limit switch on the level gauge, loosen the nuts (D), move the switch to the desired
height and tighten the nuts (D) again.
The position of the reading point of the float with respect to the switching point of the limit
switch can vary from one type of float to another. If it is the first time that the switching point
is adjusted, with the float in a stable position, move the limit switch until the reed sensor
switches.
12.4 Electrical
connection
For the electrical installation it is recommended to use multiple conductor cables, and not
single cables, in order to guarantee the cable gland will stay watertight. The connector has a
PG7 cable gland for cables with outer diameters between 4 mm and 6 mm. The numbering
of the terminals is the following:
In the female connector:
Terminal 1:
Common
Terminal 2:
NO (Normally open)
Terminal 3:
NC (Normally closed)
Earth terminal: Not connected
D
Terminal 2 is the normally open contact when the float is below the limit switch.
