1.11 MIB (Manual Interface Board) Service Procedures
The MIB (Manual Interface Board) oversees and controls filtration. It receives and sends data over the
CAN (Controller Area Network) to and from various sensors and computers. It activates the filtration
cycle, controlling when actuators should open and close.
The MIB controller is located inside the left cabinet (see Figure 4). In normal operation a cover hides
the MIB controls and the LED display is visible. The cover is held in place with three torx screws. In
normal operation, an “A” is displayed for automatic mode. The MIB control board is useful for
diagnostic purposes. It allows manual operation of both the actuators and filter pump without using
the M2007 computer.
