The AP1 control system can detect and alarm a low material level condition in up to three (3) material hoppers. The material hopper assignments on the display are “Machine Hopper 1,” “Machine Hopper 2,” and “Drying Hopper.” Although your naming conventions may vary, the low material level detection capability of the AP1 can still be exploited. Refer to the provided electrical diagram for the proper wiring of the required level detection hardware.

Low material level detection will not be performed for this hopper.

Low material level detection will be performed on this hopper provided that the dryer is running.
