Introducing the Low Oil Volume Fryer
The Low Oil Volume (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
• 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.
• M3000 computer — a sophisticated controller with multiple levels of programming.
• Automatic fi ltration — the fryer performs hands-free fi ltering at prescribed cook cycle counts or at
prescribed times.
fryer include:
• Oil savings — The combination of a low-volume fry vat and oil automatically kept at a optimal level,
reducing oil usage.

The LOV™ Systems
Auto Top 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 (Resistance
Temperature Detector) 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 pump.
A circuit board, the AT O (Automatic Top Off), is
located inside a box behind the JIB. It monitors the
oil-level R TD 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 AT O sends a signal to the MIB (Manual
Interface Board), which then sends a signal to the
AIF to open the actuator on the return valve of the
frypot to be topped off.
Once the actuator has opened the return valve, oil is
pumped into the vat for a specifi ed amount of time
(approximately 60 seconds). When the ATO RTD
detects a temperature within 55°F (30°C) of setpoint, it is satisfi ed and the actuator closes the valve.

The system is not suited to fi lling 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 setpoint. That temperature is monitored by
the temperature probe. The activation of the system
is handled by the fryer’s computer , the M3000. The
automatic top off system is also inactive during
fi lter dispose cycles.
The system works the same in McDonald’s gas and
electric LOV
The level of the reservoir, or JIB, is monitored by
the ATO and the M3000 computer. If a low oil
condition is not rectifi ed with two top off attempts
or within 6 minutes, the low JIB light is illuminated
on the front of the fryer. It will stay illuminated until
the JIB is replaced and the orange button has been
pressed and held to reset the light (see page 34).

LOV™ Generation II Technical Reference
Auto Filtration (MIB and AIF)
The auto fi ltration system is controlled by the
M3000 computer, the AIF (Automatic Intermittent
Filtration) board and the MIB (Manual Interface
Board). The fi ltration is made hands-off by
actuators operating the drain and return valves.
The computer is programmable, and it allows 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 illuminating a
blue LED on the front and a text prompt on the
computer. The operator can say no; cooking can
continue.
An AIF board is mounted under each fry vat.
Responding “yes” leads to communication between the MIB and the AIF boards. The MIB 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. 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 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.
(2) Actuators open and close the
drain valve and return valve, (3)
emptying and refi lling the frypot.

Oil Return Sensor Troubleshooting (Gas LOV™ Fryers)
The oil return sensor is a device that is used
to prevent dry fi ring of the burners. The
sensor looks similar to a high limit. The
sensors are energized when the computer
is powered on with a soft on. The sensor
heats up and detects the oil around it.
During fi ltration when the oil is drained, it
senses the difference between the oil and
air. It is controlled with a board located
next to the interface board (right) and a
separate egg shaped plastic device (far
right) that contains additional electronics.
Use care when working with the sensor as
temperatures may reach as high as 500°F
(260°C).
The oil return sensor is controlled by a small green board
and the electronics inside the plastic, egg-shaped device
shown above to prevent dry fi ring.
10
LOV™ Generation II Technical Reference
IS VAT FULL?
IS DRAIN CLEAR?
If oil is surrounding the heater, the oil will prevent the heater from ever reaching its setpoint. Once
oil is removed during fi ltration, the heater reaches setpoint and cycles a thermostat every four
seconds. Since the cycle is only four seconds long, the seven second delay is not made and the gas
valve won’t open.
The 120VAC is on T2 in the control box traveling in on pin 11 of J3 and out pin 7 on J1 (DV) or pin
7 on J3 (FV).
Typical sensor-related failures:
•
Low temp but no call for heat (heat light),
•
Stuck in melt cycle with no call for heat,
•
Filter error (
If the computer doesn’t exit melt cycle or continues to display low temp and does not heat,
ensure that the gas supply, gas valve, and other components are working properly. If no heat lamp
illuminates because no call for heat is initiated, check the following (see diagram below):
Power to oil sensor (from previous basket lift relay on interface board K1(DV) or K4 (FV)). Check
•
pin 7 on J1 (DV) or pin 7 on J3 (FV) for 120VAC.

•
120VAC is present with oil in the vat. If the vat is empty, the power will cycle 4 seconds on, 4
seconds off.
Check between pin 3 and 2; 5VDC for air and 0VDC for oil. A common message for a shorted
•
harness or issue is
Check ground on pin 2 on relay board to stud for a secure ground.
•
Check AIF communication harness. Interrupted communication will prevent the fryer from

RTI-equipped Systems
Some stores may be equipped with RTI oil storage systems. If so, some of the settings, wiring, and
troubleshooting may differ from normal LOV™ fryer systems. (See next page for bulk oil wiring.)
The LOV™ fryer will ONLY operate with RTI systems that have the new RTI updated threepole fl oat switch. If the fl oat switch is the older two-pole switch, call RTI. These fl oat switches are
polarity specifi c and may short to ground and damage an MIB board.
Normal AC Voltage Measurements (MIB J6 8 pin connector with everything connected)
Pin 1 to Pin 2 - 24 VAC.
•
Pin 2 to Pin 8 - 24 VAC when waste tank is full, 0 VAC when it is not full.
•
Pin 2 to Pin 3 - 24 VAC when RTI fi ll pump is on, 0 VAC when it is off.
•
Troubleshooting
The valves and pump should be off while MIB is resetting. If any of the valves or pumps are on during reset then the MIB board is bad or wires are shorted.
If JIB valve is not opening, measure when JIB valve supposed to be open:
Voltage at MIB board from Pin 1 to Pin 2 should be 24 VAC; if not, check connections from
•
RTI 24VAC transformer and check transformer.
JIB solenoid is not opening:
Take these readings when the JIB valve is in the open position:
Reset the power; wait 60 seconds and see if the valve opens.
1.
Check voltage at ATO board on J8. Pin 9 to Pin 16 should be 24 VAC.
2.
RTI pump is not operating or JIB is not fi lling:
1. Voltage at MIB board from Pin 1 to Pin 2 should be 24 VAC; if not, check connections from
RTI 24VAC transformer and check transformer at RTI.
2. Voltage at MIB board from Pin 2 to Pin 3 should be 24 VAC; if not, check MIB board is bad
or wires to pump relay are shorted or both.
3. Voltage at Add pump relay should be 24 VAC; if not, check wiring from MIB board. Relay
located on top of RTI system.
Waste full signal: Pin 2 to Pin 8 should be 24 VAC when full, 0 VAC when not full; if no voltage
level change, then the connection from RTI switch or MIB board is bad.
