Weigh hopper does not
empty completely.
Check the dump time setting. It may be set too short.
If this does not correct the problem, clean the weigh hopper and recheck
the scale diagnostics readout. If not showing (0) zero when empty, re-
calibrate the scale.
Problem Possible solution
Blender does not make
rate.
Verify application is not exceeding blender capacity.
Verify additive percentage is not higher than designed, resulting in
excessive dispense time.
Verify all materials are feeding freely through the metering gates.
I have changed the recipe
entry mode, batch size,
inventory shutdown or
feeder type and alarm
flags, but the change
hasn’t taken place.
All of these settings are part of the current running recipe. This makes it
easy for the operator to load a stored recipe without having to reconfigure
all of these parameters for the new recipe. All you have to do is touch
“Accept New Recipe” to load these values into the running recipe.
A feeder always puts too
much material in the
batch.
Check that the Gate Cycle Time is set correctly. If it is then lower the
Initial % of Target to Meter. These are found under Feed Algorithm
Options. Make small adjustments and retest.
Increase the Gate Cycle Time. This is found under Feed Algorithm
Options. Make small adjustments and retest.
Increase the Allowed Underfeed value under Feed Algorithm Options.
A feeder is retrying more
than 2-4 times.
Decrease the Retries before Double Gate Time.
