400.5 NCC DT-10 (Determinator) Automatic Timer Controller
The DT-10 (Determinator) Automatic Timer Controller uses a differential pressure transmitter connected
to a solid state timer control to initiate the cleaning cycle at user input differential pressure points. When
the differential pressure across the filter elements reaches the high set point, the control will begin the
cleaning sequence until the low differential pressure set point is obtained. The control will then end the
cleaning cycle until the high set point is reached again. At this point, the control will re-initiate cleaning
beginning with the next to last row cleaned.
