LOV™ Generation II Technical Reference

Auto Filtration (MIB and AIF)

The auto filtration system is controlled by the M3000 computer, the AIF (Automatic Intermittent Filtration) board and the MIB (Manual Interface Board). The filtration is made hands-off by actuators operating the drain and return valves.

The computer is programmable, and it allows filter 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

filtration during busy times, such as the lunch rush.

An AIF board is mounted under each fry vat.

The fryer prompts for filtration by illuminating a blue LED on the front and a text prompt on the computer. The operator can say no; cooking can continue.

Responding “yes” leads to communication between the MIB and the AIF boards. The MIB controls and oversees the filtration; the AIF board operates the actuators, which open and close the valves.

The MIB is in the fryer cabinet. It is partially covered by a sheet metal cover and the LED display is 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 45).

(1)Responding to the Blue LED filter prompt with “yes” starts a filter cycle that lasts about as long as a cook cycle (approx. 4 minutes). Communication between the M3000 computer, the manual interface (MIB board), and the automatic intermittent filtration (AIF board) handle the process.

(2)Actuators open and close the

drain valve and return valve, (3) emptying and refilling the frypot.
