WARNING:

following

the safety instructions
in

The low
level indicator
sends
a
signal
to an external
device when the
adhesive
level in the
applicator's
tank
is low.
The external device
can be
a Nordson
vacuum hopper
feeder
that automatically
adds more adhesive,
or a customer-supplied
light
that warns
operators when
the adhesive
level is low.
The low level indicator
consists of a float,
counterweight, lever rod,
mercury
switch and terminal
block. The float
is balanced
by the
counterweight
to ride half in
and half out
of the hot melt material.
As the
adhesive level
drops,
the
float
attached
to the lever rod
drops down. The
mercury
switch attached
to the lever
rod tilts forward.
This action causes
the mercury
switch
to close and
activates the
terminal block.
The indicator
is intended for
30 VAC maximum,
Class
2
circuit operation
as defined
in Article 725
ot the National ElectricalCode.
