FulfillRetrofit Kit −DuraBlue/VersaBlue 25L and 50L Melters 13
Part 1105309A
E2010 Nordson Corporation
Theory of Operation
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 Fulfill system control box. A delay timer prevents
the fill system from frequently cycling on and off.
At the end of the delay, the control box 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. When the adhesive in the melter
tank reaches the desired level, the control box shuts off the solenoid valve to
stop the flow of adhesive.
The control box 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.
A safety interlock switch detects whether the melter tank lid is in place. If the
tank lid is not in place, the fill system will not operate.

adhesive as much as possible when emptying into the bin. Do not get the
adhesive wet.
FulfillRetrofit Kit −DuraBlue/VersaBlue 25L and 50L Melters 15
Part 1105309A
E2010 Nordson Corporation
(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:
SA venturi pump to draw in and transport the adhesive.
SA 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:
SThe filter stack contains a replaceable filter sock to prevent adhesive
fines and talc/powder in the adhesive from being emitted into the ambient
air.
SThe fill tube attaches to the adhesive transfer hose.
SThe baffle prevents adhesive from entering the filter sock.
SThe deflector distributes adhesive evenly in the tank.
A safety interlock switch detects whether the melter tank lid is in place. If the
tank lid is not in place, the fill system will not operate.
