Problem
Process Protection
Differential
- If the difference
between the delivery tempera-
ture exiting the delivery air
heater and the temperature of
the air entering the hopper is
greater than 175°F {97°C} for
longer than 180 seconds it
shuts down the dryer.
Possible cause
The air lines between the dryer and hop-
per are restricted or loose.
The dryer is located too far away from
the hopper.
The delivery RTD is loose or has fallen
out.
The delivery air blower is not running.
The delivery air hose is not insulated.
Solution
Check for air flow blockages or loose
hoses between the outlet of the dryer and
the inlet of the hopper. Straighten any
crimps in the hoses. Tighten any loose
hoses.
The dryer and the hopper should not be
located more than 10 feet {3 m} apart.
Check the delivery RTD and tighten if
needed.
Correct the cause of the non-functioning
blower.
Insulated hose is required for high dry-
ing temperatures.
