A - The indicator turns green when the system is
performing a refill. Note that the solenoid will pulse on
and off while the indicator is green.
B - This is a voltage from an ultrasonic distance sensor
located in the refill funnel of the InvisiPac. It is
measuring the distance between itself and the surface
of the glue located in the melter. As the glue is
consumed, the distance between the sensor and the
glue surface increases - this corresponds to a higher
voltage on the screen. The voltage from this sensor will
typically fluctuate between 3.111 V (full) and 3.296
(nominal trip). Deviations outside of this range by 0.200
mV are not uncommon. The trip point will adjust with
the flow rate to avoid thermal shocks to the melter
during periods of higher demand.

C - The amount of time it took for the previous fill event
to complete. When using Hopper Auto or Bin Auto a
refill time of 4000ms is ideal, please refer to section E
for optimization of these devices. Auto-Adaptive will
typically seek out 5000ms. Ranges that will work are
1000ms - 8000ms.
If the refill time is above 6500ms, open up the airflow on
the restrictor by turning the knob counter-clockwise.
If the refill time is below 2500ms, restrict the airflow on
the restrictor by turning the knob clockwise.
If the number is in range, and the pump is running
away, check the following:
1. Is the material temperature hot enough to keep up
with the melt rate requirements of the application.
2. The application is not overrunning the system.
3. Inspect the funnel for bridged glue around the walls
obstructing the level sensor's view of the glue.
D - The number of pump cycles occurred after the last
refill. Typically, this will be around 3 pump cycles. If it is
over 4, inspect the system setup for overfilling.
E - This graphic is present for Hopper Auto and Bin
Auto. This is an aid for optimizing how much restriction
to apply to the venturi feed system. If the system is
filling too fast, it could overfill the melter. If it fills too
slow, it may not be able to keep up with production.
If the indicator is sitting near the fast red zone, apply
more restriction by turning the knob clockwise.
If the indicator is sitting near the slow red zone, first
confirm that the hopper or bin has sufficient pellets in it.
If there are enough pellets to cover the venturi, allow
more air to flow to the venturi by turning the knob on
the restrictor counter-clockwise.
F - This indicates that the pump solenoid is energized
whenever it is green.
G - The up/down indicators turn green when the pump
is traveling in the respective direction.
