Dispensing
VCH - Vacuum Chamber High Level
format:
xxxxx
(lbs. or kgs.)
function(s):
Vacuum chamber fill dispense target. Also known as “fill weight”.
VCL - Vacuum Chamber Low Level
format:
xxxxx
(lbs. or kgs.)
function(s):
1. When starting, if an amount of material equal or greater to this level is detected in the
vacuum chamber, a “Warning: Material in Vacuum Chamber” message will pop up.
2. When in Clean-Out mode, the vacuum chamber fill valve will not open automatically
until the vacuum chamber weight reading is at or below this level.
3. The minimum allowable final dispense of a standard Auto Stop.
RHH - Retention Hopper High Level
format:
xxxxx
(lbs. or kgs.)
function(s):
Retention hopper fill dispense target. This value is typically slightly higher than VCH to
ensure that 100% of the vacuum chamber contents dispense into the retention hopper.
RHL - Retention Hopper Low Level
format:
xxxxx
(lbs. or kgs.)
function(s):
1. When starting, if an amount of material equal or greater to this level is detected in the
retention hopper, a “Warning: Material in Retention Hopper” message will pop up.
2. When in Clean-Out mode, the vacuum chamber dump valve will not open
automatically until the retention hopper weight reading is at or below this level.
3. When the dryer is running, the retention hopper must be depleted down to this level
before a vacuum chamber dump is allowed.
BLK - Bulk Density
format:
xxxxx
(lbs./ft
3
or g/L)
function(s):
User-enterable. Setting this correctly ensures that a fill weight that could potentially
overflow the vacuum chamber cannot be entered. Note: has no effect on drying.
VFR - Vacuum Chamber Fill Rate
format:
xxxxx
(g/sec.)
function(s):
Learned flow rate of the vacuum chamber fill valve. This parameter will automatically
adjust over time. As it adjusts, vacuum chamber fills will converge on the targeted fill
weight.
