(1) Responding Yes to the Blue LED
fi lter prompt, sets in motion a fi lter
cycle that lasts about as long as a
cook cycle. Communication between
the M2007 computer, the manual
interface, or MIB board, and the
automatic intermittent fi ltration, or AIF
board, handle the process. (2) Linear
actuators open and close the drain
valve and return valve, (3) emptying
and refi lling the frypot.
Auto Filtration (MIB and AIF)
The auto fi ltration system is controlled by the
M2007 computer, the AIF (Automatic Intermittent
Filtration) board and the MIB (Manual Interface
Board). The fi ltration is made hands-off by linear
actuators operating the drain and return valves.
The computer is programmable, allowing fi lter
cycles to be launched after a set number of cook
cycles and a prescribed elapsed time.
The system can be set to lock out automatic
fi ltration during busy times, such as the lunch rush.
The fryer prompts for fi ltration by fl ashing a
blue LED on the front and a text prompt on the
computer. The operator can say no; cooking can
continue.
A Yes response leads to communication between the MIB and the AIF boards. The MIB is the more
robust board. It controls and oversees the fi ltration; the AIF board operates the actuators, which open
and close the valves.
The MIB is in the fryer cabinet and partially covered by a sheet metal cover. The reset button and the
LED display are visible. Buttons behind the cover allow limited manual operation of the system and
its valves. The cover should be reinstalled after service.
The LED displays codes that can be used to diagnose failures (see chart on page 44).
An AIF board is mounted under each fry vat.
