Section 2-- Identification and Function of Parts 2-15

2.5.1.4.2 DWELL ADJUSTMENT

The length of the air blast required to divert unwanted objects in the product stream

to the reject chute is different for various products. The length of time that the

ejector is kept on after it is actuated is called Ejector Dwell. A correct setting of the

Dwell time will allow even the largest object to be efficiently rejected but not

unnecessarily remove excess good product.

The Dwell button provides an adjustable Dwell time from 0.8 milliseconds to 2.2

milliseconds in 0.1 millisecond increments. A Dwell button setting of 12 (1.2 ms) is

most common for small and medium grain products.

2.5.1.5 LAMP FAULT BYPASS

Although it is not recommended, at times it may be necessary to run the sorter even

though a lamp fault has been detected. To allow normal operation of the feeders

during a lamp fault, touch the LAMP FAULT BYPASS button. The button will change

from NO to YES, and the feeder button on the MAIN SCREEN will start and stop the

feeder. It is not important that the BYPASS button be changed back to NO when the

lamp fault is corrected.

2.5.2.1 TRIP MODE

The type of object that will be considered as a defect is set by the FRONT TRIP and

REAR TRIP selector buttons. In the DARK mode, only those objects that are darker

than normal will be ejected. In the LIGHT mode, only those objects that are lighter

than normal will be ejected. In the BOTH mode, objects that are either darker than

normal or lighter than normal will be ejected. In the OFF mode, the ejectors will not

fire at all.

2.5.2.2 SORT MODE

The sorting configuration can be selected for several different types of sorts.

In the reflective mode, the product will be illuminated from both sides. In this REFL

mode, products can be color-sorted by light trip, dark trip, or both light and dark at

the same time.

The translucent mode is used for sorting opaque objects from a stream of

translucent objects. In this TRANS mode, the lamps in the front of the viewer are

turned off, and the rear lamps backlight the product. Particles that are opaque will

appear dark, and can be removed by using dark trip. Translucent products that are

significantly darker than the average good products will also be removed by using

dark trip. Only the front view background is adjusted in this mode.
