Milk Weight Trays
The Xpress machine monitors the available milk levels using two milk
weight trays. Each milk container is weighed independently. Milk levels
are monitored using the milk weight trays and a notification message is
displayed when milk levels are low or empty.
The milk containers sit on the milk weight trays and as the milk level
drops, the milk weight tray rises, increasing the gap between the milk
weight tray sensor magnet and the sensor. A low milk level of
approximately 25 percent of the milk container volume will result in the
LOW MILK – FRONT or LOW MILK – REAR message to be displayed.
A single, large milk weight tray is available. This milk weight tray allows
for two containers of a single type of milk to be used. If a large milk
weight tray is in use, ensure that SPECIAL FEATURES > SINGLE MILK
AUTO SEL is selected.
A small milk weight tray is designed to hold a single milk container, and a
large weight tray is designed to hold two milk containers or one large
container.
.25 gallon (.95 liter) of milk in front container
remains.
.10 gallon (.38 liter) of milk in front container
remains.
Tray sensors are not detecting the milk weight
tray magnet. The milk weight tray is not installed
correctly, is missing, or is incorrectly adjusted.
Similar messages appear for the rear milk weight tray.
NOTE: When initially inserted into the on-board refrigeration unit, the
milk weight tray does not lie flat. The springs on the right hand side of the
milk weight tray naturally lift the right side up about 1/4” (.64cm). With a
full milk container on the milk weight tray, it will lie flat.
