1-12. Controls
The M081 Asphalt Mixing Plant is designed to be operated automatically through a blending controller. This controller is a
specially designed industrial computer. The plant may also be operated manually without the use of this blending
controller. However, manual operation is not recommended as the quality of the product may not be to the high standards
attainable through the blending controller.
The functions of the operator control panel are processed through a Programmable Logic Controller (PLC). This controller
contains the programmable logic required to perform many electrical functions of the plant. Sequencing of electrical
motors, time delays and sensor monitoring occurs within this PLC. Some of these functions may be altered by the plant
operator.
The Asphalt Mixing Plant has a training mode which is accessed through the PLC. This permits control panel training of
operators without running the components of the AMP.
