Setting Mid-Grain Temperature Alarm Limits

Since the speed of the discharge impacts the mid-grain temperature, it is on any of these discharge settings pages where the operator can set the mid-grain temperature alarm limits. If the dryer is discharging and the mid-grain temperature exceeds the mid-grain temperature alarm band for a set period of time, the dryer will enter a Cool Down mode. The two alarm limits that can be entered that pertain to the mid-grain temperature are the Alarm Band and Alarm Band Delay.

Alarm Band

The Mid-Grain Temperature Alarm Band is the allowed deviation from the mid-grain temperature set point while the discharge system is running.

Alarm Band Delay

The Mid-Grain Alarm Band Delay is a user-defined time duration in minutes that will delay the Cool Down of the dryer after the Mid-Grain Band warning alarm has occurred. If the Mid-Grain temperature returns to the acceptable range within this time period, no shut down will occur.
