Theory of Operation
NOTE: Refer to Appendix A, Retrofit Refill System With Nordson Level Sensor, for updated
information.
Overview
The system adds small quantities of adhesive to the sealed tank at regular
intervals, reducing the possibility of adhesive char, contaminants, thermal
shock and incorrect adhesive temperatures that result in poor bonding.
A capacitance sensor located in the melter detects low adhesive level, and
then sends a signal to the system control. A delay timer prevents the fill
system from frequently cycling on and off.
At the end of the delay the control activates the vacuum via a solenoid valve.
Air pressure flows to a suction lance that is placed in the supplied bulk
adhesive container. Using vacuum, the system conveys adhesive from the
bulk container to the adhesive melter tank.
The controller activates the suction lance for a limited amount of time to
prevent over‐fill conditions. If the maximum fill time is exceeded, the
controller activates a fault that stops the system from filling.

Place adhesive in the adhesive storage bin. The bin contains a gasket that
prevents debris from entering the bin. For best results, break up the
adhesive as much as possible when emptying into the bin. Do not get the
adhesive wet.
(2). Air Pressure Regulator/Solenoid Assembly
The supplied air pressure regulator is permanently set at 65 psig, the optimal
setting for most adhesives.
The solenoid valve turns on after the sensor indicates level state and the time
delay has been reached. The solenoid directs compressed air to flow to the
suction lance.

(3). Suction Lance
The suction lance draws adhesive from the adhesive storage bin. The
suction lance includes:
A venturi pump to draw in and transport the adhesive.
A vibrator to keep the adhesive in loose condition. The vibrator is active
as long as compressed air is supplied to the suction lance.
Air line tubing and the adhesive transfer hose are connected to the suction
lance. The lance is placed in the PVC pipe located in the adhesive storage
bin.
(4). Adhesive Transfer Hose
The adhesive transfer hose connects the suction lance to the lid assembly.
The transfer hose conveys adhesive from the adhesive storage bin to the
melter tank.
(5). Lid Assembly
The lid assembly includes the filter stack, lid, fill tube, baffle and deflector:
The filter stack contains a replaceable filter sock to prevent adhesive
fines and talc/powder in the adhesive from being emitted into the ambient
air.
The fill tube attaches to the adhesive transfer hose.
The baffle prevents adhesive from entering the filter sock.
The deflector distributes adhesive evenly in the tank.
The thumb screws mount the lid to the melter. The thumbscrews can be
replaced by Allen head screws supplied in the ship with kit. Do not remove
the lid during operation, unless the system is disabled by turning power off at
