LOV ™ Generation II T echnical Reference 1 The Low Oil V olume (LOV ™ ) fryer is a McDonald’ s-only , feature-laden version of the electric RE fryer or gas H55 fryer . The enhancements found on the LOV ™ fryer include: • Low volume frypot — 30 pounds (15 liters) rather than 50 pounds (25 liters) of oil.
LOV ™ Generation II T echnical Reference 2 Auto T op Off The core of the system is the automatic top-off board, which senses when the oil level is low and fi lls the pot to the top line. The oil level is monitored by an R TD ( R esistance T emperature D etector) sensor in the frypot at the upper oil level.
LOV ™ Generation II T echnical Reference 3 The A T O board is positioned under the LON gateway in a box with a transformer that provides power to the board. The LON gateway must be removed to access the A T O board. The reservoir , or JIB, rests behind the right door of the fryer .
LOV ™ Generation II T echnical Reference 4 Problem Probable Causes Corrective Action Frypots won’t top off. A. Probe temperature lower than setpoint. B. Oil is too cold. C. Bad Connection. D. A TO board power loss. E. Failed transformer/harness. F .
LOV ™ Generation II T echnical Reference 5 (1) Responding to the Blue LED fi lter prompt with “yes” starts a fi lter 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 fi ltration (AIF board) handle the process.
LOV ™ Generation II T echnical Reference 6 Manual — Used to toggle between automatic and manual fi ltration mode. The unit must be in manual mode for the other MIB buttons to operate. Select — Used to scroll through the vats, which are shown numerically in the LED.
LOV ™ Generation II T echnical Reference 7 1L, 1r - 5L, 5r — Numbers correspond to vats: “L” indicates the left side of a split vat. “r” indicates a full vat or the right side of a split vat. A — Auto mode: auto fi ltration enabled. E — Drain or r eturn valve not in desired state: display alternates between E and vat number .
LOV ™ Generation II T echnical Reference 8 Problem Probable Cause Corrective Action Auto fi ltration won’t start. Filter pan out of position. Oil Level is too low . Ensure MIB board is not in manual mode. Ensure MIB cover is not damaged and pressing against buttons.
LOV ™ Generation II T echnical Reference 9 Problem Probable Cause Corrective Action MIB board alternat- ing “E” and “vat number and side.” Network error on the CAN bus communication.
