PNEG-900 Series 2000 Autoflow Fan/Heater and Control Installation Instructions 17
Multi-Grain Temperature Sensor
1. Remove the two (2) wires attached to the grain temperature sensor connected to terminal #22 and
terminal #23 in the fan control box.
2. Mount the four (4) grain temperature sensor brackets evenly around the drying chamber on outside
leveling band posts. (See Figure 3I on Page 18.)
3. Mount the brackets with bin bolts so that the sensor is 8-1/2" above the floor sheet rib for Auto drying
mode and 10-1/2" above the floor sheet rib for Batch drying mode. For AUTO drying, the bottom hole
in the mounting bracket should align with the third hole from the bottom of the leveling band post.
For BATCH drying, the bottom hole in the mounting bracket should align with the fourth hole from the
bottom of the leveling band post.
4. Wire tie the cords so they feed up the leveling band post and across the top leveling band.
5. Route the cords through the space between the roof and the top sidewall sheet. There should be
enough on all temperature sensor brackets to exit the drying chamber at the same place.
6. Route the cords into the junction box after the junction box has been mounted to the bin.
7. Wire the four (4) temperature sensors as shown in Figure 3H and on Page 19 .
