(This module has provision for mounting an H20-93A photo detector to report head entry.)

The Grain Feeder is capable of delivering almost any dry food of small, granular structure. It is commonly used for bird seed or extruded, pelletized feed commonly formulated for pigeons. It may also be used to deliver small pieces of other dried feeds such as shrimp.

To operate the feeder, connect it to one of the "Feeder" connectors on the ECB and time the operate signal, allowing sufficient time for the animal to consume the desired amount of food. You may find it behaviorally advantageous to mount detector heads on the unit to permit bringing up the feeder with an operate and starting a timed interval upon head entry to delay the drop to allow the desired access time after head entry. It can be used for monitoring ad lib. feeding when used with the photo detector.

The entire food hopper lifts off for filling and cleaning. Simply lift up until the pivot pin clears the pivot groove in the arm. Then move it rearward so that the bottom is clear of the trough and the hopper is balanced properly.
