Summary
Bindicator(s)
Lower bindicator is installed on side of dryer, just below garner section of dryer. Upper bindicator is only
installed on conveyor or slide gate fill dryers. Install bindicator(s) within easy reach of outside ladder for
later wiring.
Electricians will install conduit and wire bindicator(s).
Grain Temperature Sensor (RTDs)
Grain temperature sensor is installed within reach of outside ladder at burner access door location.
Electricians will install conduit and wire grain temperature sensors.
High-Limits (Overheats) (3)
Upper High-Limit, middle High-Limit, and lower High-Limit (each with copper tubing) are installed on
perforated sheets, between top row of solid sheets and (just above or just below) middle row of solid
sheets (at grain turners). Locate Junction boxes under outside ladder.
Construction crew will install conduit connecting High-Limits and continue conduit down to about
10' above foundation. Electricians will wire High-Limits.
