Intended Use
S Same as the melter. Refer to the melter manual.
Unintended Use
S Same as the melter. Refer to the melter manual.
Melter Firmware Requirements
Operation of the fill system requires that melter firmware version 2.076 or
later be installed in the melter. Firmware updates are available from
www.enordson.com/support.
Theory of Operation
The fill system adds small quantities of adhesive to the sealed melter 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 a 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 overfill conditions. If the maximum fill time is exceeded, the controller
generates a refill alarm that stops the system from filling but does not disable
the melter heaters or take the melter out of ready status. If used, a refill alarm
output is generated when the maximum fill time is exceeded. A refill alarm
can be cleared via the control panel or the Clear Refill Alarm input, if used.
NOTE: The low level LED present on a standard ProBlue melter is not
present on a Fulfill integrated melter.
