GSI Outdoors PNEG-1153 Moisture/Matic Electrical Box and Sensor Installation Instructions, 4.INSTALLATION, Sensor Cut-Outfor Round Down Spouts

4.INSTALLATION

4.For conditions where straw or chaff can accumulate in the restrictor funnel, the grain can be channeled over the sensor with angled brackets in the down spout. (See Figure 4N).

Figure 4N

Sensor Cut-Out for Round Down Spouts

1.When using a sensor in a down spout, there must be a CONSTANT density of grain flowing over the sensor for accurate readings. This flow must be independent of the flow or velocity of the grain stream. It is recommended that a restrictor be used to slow the grain speed over the sensor such as used in Step . A modified open top version may have to be used.

Moisture/Matic Electrical Box and Sensor Installation Instructions

1.The Calc-U-Dri Moisture/Matic can be near the unit’s main control box, discharge auger, or other locations that are easily accessible and of convenient height for you to observe and use. Mount the electrical box using four (4) 5/16" x 1-1/2" bolts, lock washers and nuts.

2.Included with the Calc-U-Dri Moisture/Matic are 27 feet of one-half (1/2)" liquidtite conduit. This is to be used to protect the sensor wire between the Calc-U-Dri Moisture/Matic box and the sensor.

3.A 4 x 4 junction box, sensor wire, and liquidtite is available to extend the sensor wire up to 250 feet, if required. Determine the shortest distance from the sensor to the junction box. Use the 27 feet of one-half (1/2)" liquidtite conduit and feed the sensor wire through it using the connector provided. There should be six (6)" of sensor wire inside the junction box. Any excess wire or conduit may be cut off. Be sure not to cut off too much since both the conduit and the sensor wire need to be connected at the other end to the Moisture/Matic box.

4.Connect the Calc-U-Dri sensor wires in the 4 x 4 junction box to the top of the terminal strip. The leads from the Moisture/Matic box go to the bottom of the terminal block. Be careful to match the color coded wires to each other - red to red, etc., (See Figure 4O). Then attach the junction box lid.
