Sterlco MDB Series Dryers - Manual (Page 43)

Dryer & Drying Hopper Faults
Faults fall into two broad categories.
• Critical Faults – Shuts down equipment.
• Non-Critical Faults – Does not shut down equipment.
Critical faults are assigned to conditions that could cause damage to either the dryer
components or the material in the drying hopper while non-critical faults are assigned to
conditions that would allow an undesirable or inefficient Process condition to exist.
Because the Process and regeneration systems of the dryer operate independently, it is possible
that a condition exists in the regeneration system that prevents it from operating while the
Process system continues to operate without error.
