3.7. Grain Level Switches
Overview
In continuous mode the system is capable of monitoring five safety/operational switches. The following three
switches are included with the system and are field-installed:
• Fill Dryer switch
• Low Dryer switch
• Plugged Discharge switch
Two optional switches (customer supplied and installed) can be wired into the dryer control:
• Wet Bin Empty switch
• Dry Bin Full switch
Fill Dryer Switch and Low Dryer Switch
Note
Location of the Fill Dryer and Low Dryer switches depend on the style of fill and configuration of the
intake grain supply. Refer to the figures in this section for details.
• The Fill Dryer switch senses the presence of grain. It signals the PLC to shut off the filling auger.
• The Low Dryer switch is designed to shut off the dryer just before any ducts are empty so that fuel will not
be wasted.
Note
The Commander Control ignores the loss of signal from this switch for a period of time to prevent
nuisance alarm triggers due to grain movement.
