The Low Oil Volume (LOV™) fryer is a McDonald’s-only, feature-laden version of the RE fryer
introduced in
2006
2006. The enhancements found on the LOV™fryer include:
• Low volume frypot —30 pounds (15 liters) rather than 50 pounds (25 liters) of oil.
• Automatic top-off — the fryer automatically maintains an optimal oil level with a reservoir in the cabinet.
• M2007 computer — a sophisticated controller with multiple levels of programming.
•Automatic filtration — the fryer performs hands-free filtering at prescribed cook cycle counts or at
prescribed times.
• Oil savings — The combination of a low-volume fry vat and oil
automatically kept at a optimal level, reducing oil usage.
A similar fryer, the Protector, is available for the general market. It has the
LOV™’s auto top-off feature and the on-board oil reservoir, the smaller fry vat
and the oil savings associated with smaller vat and the top-off feature.
Filtering using the CM7 computer on a Protector fryer is manual.

Auto Top Off
The core of the system is an automatic top-off
board, which senses when the oil level is low and
fills the pot to the top line.
The oil level is monitored by an RTD sensor in
the frypot at the upper oil level. The oil is moved
to the pot from a reservoir, called a JIB (Jug In
Box), to the frypot with a small pump.
A circuit board, the ATO (Automatic Top Off), is
located inside a box behind the JIB. It monitors
the oil-level RTD and activates the pump when
it senses an oil temperature drop of 60°F (33°C)
below setpoint, indicating the oil has moved
away from the sensor. The oil is pumped into a
solenoid tree and the ATO opens the solenoid for
the frypot that needs oil.
Oil is pumped into the tank until the ATO detects
a temperature within 55°F (30°C) of setpoint.
The system is not suited to filling the frypot when
it is empty and there are safeguards to prevent it
from activating when the fryer is cold and the oil
is resting at the lower position.
The system is not active until the oil in the frypot
reaches 300°F (149°C). That temperature is
monitored by the probe. The activation of the
system is handled by the fryer’s computer. In
the McDonald’s system that is the M2007. The
automatic top off system is also inactive during
filter cycles.
The system works the same in McDonald’s gas
and electric LOV™systems and in the Protector
fryer, which is made for the general market.
The level of the reservoir, or JIB, is monitored
by the ATO and the M2007 computer. If a low
oil condition is not rectified in 6 minutes, the low
JIB light is illuminated on the front of the fryer.

(1) Responding Yes to the Blue LED
filter prompt, sets in motion a filter
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 filtration, orAIF
board, handle the process. (2) Linear
actuators open and close the drain
valve and return valve, (3) emptying
and refilling the frypot.
Auto Filtration (MIB and AIF)
The auto filtration system is controlled by the
M2007 computer, the AIF (Automatic Intermittent
Filtration) board and the MIB (Manual Interface
Board). The filtration is made hands-off by linear
actuators operating the drain and return valves.
The computer is programmable, allowing 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.
The fryer prompts for filtration by flashing a
blue LED on the front and a text prompt on the
computer. The operator can say no; cooking can
continue.
AYes response leads to communication between the MIB and theAIF boards. The MIB is the more
robust board. It controls and oversees the filtration; 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.

Return — Used to open and close the return
valve on the vat indicated on the display. It also
controls the pump. When pressed an LED on the
button indicates activity: slow blink, awaiting
response from AIF; LED illuminated constantly,
drain open; no illumination, drain closed; rapid
blink, no response from AIF. The pump turns off
before closing the return valve; the return valve
opens before the pump is turned on.
The mode display on the face of the MIB board
displays a range of letters, which indicate
activity or an error.

ATO (J10) boards.
Check continuity between each color
wire on the CAN connectors into J7 on
the far right computer and J10 on back
of the ATO board (black to black, white to
white, and red to red), and ensure there
is no continuity between different color
wires (black to red, red to white, and
white to black).
Ensure black computer locator wires are
connected from ground to correct pin
position (see diagram 805-1656 on page
35 of this manual). Ensure all boards
have the corner ground wire attached
and tightened.
The locator pin in J2 of the AIF board is
either loose or in the incorrect position.

Ensure actuator leads are plugged into AIF
board (J1 for FV, J3 for DV).
Check the power on the connector of the
problem actuator while manually opening
or closing the actuator. Pins 1 (black) and 4
(white) should produce +24VDC when the
actuator is opening; -24VDC should be read
from Pins 2 (red) and 4 (white) when the
actuator is closing. If either voltage is missing,
the AIF board is likely bad. Test the actuator
by plugging into another connector to open
or close. If the actuator operates, replace the

Loading and Updating Software
Loading Software from an SD card to MIB and AIF boards
To update MIB or AIF software in the field follow these steps:
1. Switch all computers to OFF. With the computer displaying
OFF
OFF, press the TEMP button to
check current M2007/MIB/AIF/ATO software version.
2. Remove the two screws on the right side cover plate of the MIB board.
3. With the MIB displaying
A
insert the SD card with the new software, with the card contacts
facing out and the notch on the bottom left, into the slot on the right side of the MIB board.
4. Once inserted, watch for a period in the display to appear on the bottom right of the MIB dis-
play, indicating the software is being downloaded. If a period does not appear, the software
on the card and on the computer may be the same version, or the boot loader software missing
or corrupt. It will not update. If this happens, contact Frymaster.
5. The period blinks several times while loading. Wait for a minimum of two minutes and the
period in the display stays off.
6. Remove the SD card from the MIB.
7. If only updating the MIB or AIF boards remove power from the MIB by carefully removing
the16-pin harness behind the MIB board or the five-pin control power cord on the rear of the
unit. If updating all the software update the MIB and then the M2007 and then remove all
power from the fryer using the five-pin control power cord on the rear of the unit.
