1.12 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 controllers. It activates the filtration cycle,
controlling when actuators should open and close.
The MIB controller is located inside the left cabinet (see Figure 6). In normal operation a cover hides the MIB
controls and only 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 controller.
