filter). The Liquid Pressure module is used to monitor the liquid
pressure level during harvest to ensure that the filter is not clogged.
The use of pumps and/or a Harvest pinch valve is optional with
this module: the pinch valve will close and the pump will stop if the
liquid pressure reads above a specified setpoint.
• Auxiliary Input
—AuxIn2 can be used to monitor sensors and
transmitters that use a 4-20 mA signal, such as external scales.
Note:
AuxIn1 is reserved for the laser distance sensor, used to
home the carriage to either the top or bottom position. As such, it is
grayed out and cannot be used in the same manner.
