Material Overdrying Protection

Material Overdrying Protection is an automatic system used to reduce the chance of over- drying, and possibly melting, the resin in the drying hopper. Material Overdrying Protection activates when the return temperature is above a set value, indicating that all the resin in the hopper is dry.

The control system monitors the return air temperature and automatically changes the process air setpoint to the SET BACK SETPOINT value when the return air temperature rises above the set back temperature. The process air setpoint returns to normal when the return air temperature falls below the SETUP TEMPERATURE value. The target values for changing the process air setpoint can be adjusted on the Mat Protect screen.
