Portable Drying/Conveying Systems Chapter 4: Operation 29 of 76
The TEMP is the set point for the return air temperature of the drying hopper. When the
return air temperature exceeds this value, after a certain delay time, the process temperature
will be reduced to its secondary value (SETPOINT) to eliminate over drying of the plastic
material.
The DELAY is the time which will take for the dryer to switch the drying temperature set
point from primary drying temperature to secondary drying temperature or back to the
primary drying temperature set point.
SET UP TEMP;
The SETUP TEMP is the secondary temperature setting for the return air temperature. When
the return air temperature of the drying is lower than this set point, after a certain delay time,
the process temperature set point will switch back to the primary drying temperature set
point.
Once the parameters have been set for the drying process, the operator can return to the
DRYER MENU, MAIN MENU, or BACK to the screen 1 of 2 of the OVERDRY
