4. INSTALLATION

Figure 4O

5.Secure the Calc-U-Dri sensor wire to the inside of the Calc-U-Dri Moisture/Matic box with the plastic “J” clips. Connect the sensor wires to the terminal strip marked “sensor”. Excess sensor wire can be cut off. Be sure the sensor wire (stripped bare of insulation) is clamped in the terminal and not on the insulation.

If more than one sensor is used, hook the sensor wires so that all like-color wires are under one terminal post. (All black wires on terminal number one, etc.,). The correct dip switch setting for the circuit board is described on the chart on page 45. Set dip switches 9 and 10 to the correct position according to the number of sensors used.

Note: The top terminal strip on the back panel of the Moisture/Matic is low voltage D.C. Never hook A.C. power to this terminal strip.

6.Mount the sensor in the discharge tube by positioning the stainless steel flag toward the grain, and the copper flag toward the discharge end. The flow of grain must follow the arrows on the sensor decal. Be sure the sensor block seats fully into the rectangular hole in the discharge auger tube. Fasten to the tube with strap bands. Fasten the grounding strap from the sensor to the discharge auger tube by drilling a self-tapping screw through the connector on the ground strap and back into the discharge tube in the area where the flighting has been removed. Leave at least two (2)" between the sensor block and the grounding screw.

Electrical Hook-up (See Figure 4P).

1.Disconnect the AC power from your dryer and lock-out the AC power to insure that it will not start.

2.DC Voltmeter Hook-up: Use the 15 foot piece of five (5) conductor cable provided for the hookup wire. Use liquidtite and proper fittings (not provided) to run between the Calc-U-Dri and the SCR controller. On the SCR control board locate the leads going to the DC motor.

a.Attach the black wire, one of the conductors in the cable, to the positive motor lead (A1) and the green wire to the negative motor lead (A2).
