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 fills the pot to the top line.

The oil level is monitored by an RTD (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 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 set- point, indicating the oil has moved away from the sensor. The ATO 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 specified amount of time (approximately 60 seconds). When the ATO RTD detects a temperature within 55°F (30°C) of set- point, it is satisfied and the actuator closes the valve.

Top off will continue on the next vat if needed. 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 rest- ing 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 filter dispose cycles.

The system works the same in McDonald’s gas and electric LOV™ systems.

The level of the reservoir, or JIB, is monitored by the ATO and the M3000 computer. If a low oil condition is not rectified 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).

The ATO board positioned underneath the LON gateway controls the top off of the fry pots.

The pump that moves oil from the reser- voir to the frypots is visible above.
