The Drying Monitor option on your Carousel Plus dryer allows you to utilize Conair's Material
Ready feature. This feature ensures that material is not conveyed to the machine until it has been
dried at the proper temperature for the proper amount of time.
H o w d o e s i t w o r k ?
When T1, T2, or T3 locations of the Drying Monitor probe reach 95% of the setpoint for a user
specified residence time, the interlock activates to allow material to convey to the molding machine
or extruder. Until the material has dried for the proper amount of time at the proper temperature, the
interlock will not allow material to be moved from the drying hopper. A material ready indicator is
shown on the dryer control or the local hopper control (HTC, ResinWorks, or GasTrac control) indi-
cating that material is ready.
If the temperature drops below 95% of setpoint, the residence timer stops until it returns to the set-
point range. It then continues counting up toward the desired residence time. For example - You
have the residence time set at 4 hours. Your material reaches 95% of setpoint and dries for 2 hours
within that range, but then drops to below 95% of setpoint for 10 minutes. After 10 minutes, your
temperature returns to 95% of setpoint. The timer begins counting at 2 hours and continues until you
reach the residence time of 4 hours. That 10 minutes did not count toward the residence time. But
the time at temperature that was achieved was banked until the material reached the setpoint tempera-
ture again. (It did not restart the timer at 0 minutes - you got credit for time the material had already
dried.)
This feature is designed to eliminate undried material making it to the molding machine, therefore
eliminating the production of parts that are inferior due to moisture in the material.
