Dear Milnor Dealer,

Recently, we have had reports from several customers of persistent Scoop Blocked faults in their 1-station press. This fault occurs when the sensors on the load chute detect the presence of material on the chute that the descending diaphragm could hit-an important safeguard. However, water that enters or remains on the load chute while the diaphragm moves down can cause an unnecessary fault. You must adjust two interrelated configure decisions to avoid this. These decisions are:

Loading Time in the press controller-Free water that comes out with the goods can remain on the press load chute for a few seconds. A value of 4 seconds is usually sufficient to allow this residual water to flow off of the load chute before the sensors are armed.

Pause at Top Dead Center in the Mentor controller-Water can splash out of the tunnel after the cylinders start to turn following transfer and cause a fault in the press. The load chute sensors remain armed until the press diaphragm enters the can on its descent. Specifically, the sensors are disarmed when the PXSM proximity switch (Ram inside Can) is no longer made (which tells the controller that the diaphragm is inside the can). The time it takes for this to occur can vary with the press model and with conditions such as whether the press is fully broken in. The value you enter here must be long enough to accommodate the press Loading Time plus the time for the diaphragm to descend into the can. As a starting point, assume a 3 second descent time. If the press Loading Time is 4 seconds, enter 70 tenths (4 + 3
