Float switch Series IGM finds application in liquid level
control in tanks and wells; it requires connection to
pumps (or other electrical equipment).
The float switch can be used with drinking water and
sewage as well as other liquids compatible with the com-
ponents of the products. Float switch Series IGM is
spray- and dust proof thanks to a double sealing obtained
by injection moulding using the same material of con-
struction for the body (non toxic polypropylene).
The IGM Series has been especially designed with very
compact size, although still retaining electrical and float
characteristics such as to ensure perfect operation.
Product reliability is ensured thanks to the sound expe-
rience of WATTS Cazzaniga in the sector as well as to the
stringent testing programme to which both the process
and product are submitted.
APPLICATION
It is important to make sure that they are no objects
impeding the float movement. If necessary, adjust the
float arm by suitably positioning it with relative
counterweight. It is good practice to position the float on
the side opposite to liquid inlet.
Electrical connection:
The three-pole cable (cable colour: Blue - Brown - Black)
allows float switch Series IGM to be used for emptying or
filling depending on the electrical connections as descri-
bed below:
- Emptying / Black - Brown connection / contact closes
with float at top
- Filling / Black - Brown connection / contact closes with
float at bottom
INSTALLATION AND ELECTRICAL
CONNECTIONS
Float switch Series IGM can be used either for filling or
emptying tanks and wells.
The important factor is the length of the rotating arm
which determines the minimum and maximum liquid
levels. For such purpose, the arm length can be shortened
using the appropriate counterweight (CP/NSD). Thanks to
its compact size, the float switch is suitable for connection
to pumps with cable lengths also shorter than 40 cm (the
rotating arm can be shortened up to 10 cm) Fig.1 and 2
illustrate the operation.
