Icon/Field Description
Pump Slow Pressure Selecttheairpressuredesiredtobeappliedtothepumpwhenrunninginpump
slow speed. Slow speed runs automatically when loading a new container of
material to prime the pump, and at the very end of an empty container. Refer to
the pump manual for minimum and maximum allowed pressures.
Pump Fast Pres
sure
Select the air pressure desired to be applied to the pump when running in
pump fast speed. Fast speed is run to evacuate the bulk of the material from
the container. Refer to the pump manual for minimum and maximum allowed
pressures.
Air Assist Pressure
Select the a
ir pressure desired to be applied under the ram plate to aid in
unsticking
the ram plate from the bottom of an empty tote.
Seal Pressure Select the air pressure desired to be applied to the seal while inside the container.
Always choose the lowest pressure that achieves the desired result. Too much
pressure reduces the life of the seal and creates excessive frictional force
opposing movement of the ram. Too little force and material will leak past the seal.
Air Assis
tPressure
Select the air pressure desired to be applied under the ram plate to aid in
unsticking the ram plate from the bottom of an empty tote.
Ram Up Pressure
Select t
he air pressure desired to lift the ram plate out of the container. Choose
the lowe
st pressure that raises the ram without lifting the container.
Ram Down Pressure
Select the air pressure desired to push the ram down against the product during
evacuation. Always use the lowest pressure that achieves the desired result. Too
much down pressure will cause material leakage around the inflatable seal.
Ram Jo
gPressure
Select the air pressure to be applied to the ram when jogging downward.
Seal P
artial Pressure
Selec
t the air pressure to be applied to the inflatable seal when the ram plate is
appr
oaching an overfull container. Choose the lowest pressure that achieves the
desi
red result. Too much Seal Partial Pressure can cause inflatable seal damage
duri
ng entry into the container, or may even cause the seal to burst.
