4Virtual Quality Management System (VQM) Terminology

Beater Run: This D.O.B. timer used to delay the beater motor after the refrigeration shuts down. Beater Run Range: 0 to 10 seconds

Demand Run Comp: The D.O.B. timer used to delay the compressor when product is being drawn. Demand Run Comp. Range: 0 to 12 seconds

Differential/ Hyst: Symbolizes the differential setting. Differential range: 7 to 20°F i.e. if your cut in is at 18°F and your Differential is at 10°F your unit will cut out at 8°F

Dual Diff: The differential used when product is being drawn out of the center spigot. Dual Differential range: 7 to 20°F

Idle: When the unit is cycling on temperature and no product is being dispensed

Idle Run Comp: Delay on break (D.O.B.) timer used for the compressor when the unit is in idle mode/no product being drawn. Idle Run Comp. Range: 0 to 20 seconds

Lock outs: Allows the function of a specific feature/button to be temporarily disabled to deter un-necessary usage of that feature.

Main P.C. Board: Main Control board for the unit, housed behind the trim strip panel. This board has many connectors on it and is responsible for the main operations of the unit.

Membrane Switch: The black Electro Freeze decal visible on the front of the unit, which houses the hidden operator, technician, soft, and hard keys used to navigate the menus

Relay Board A control board located in the main electrical control box. This Board contains no software, only solid state control relays to operate system components.

Single Diff: The differential used when product is being drawn out of one barrel. Single Hysteresis range: 7 to 20°F

8

184559

Soft Serve Freezer Model GES-102

4Virtual Quality Management System (VQM) Terminology (continued)

Slope/Demand Slope: Utilizes a function within the system to watch the temperature change as the unit freezes a barrel. If utilizing the slope feature and the unit sees a lack of temperature change during freeze down, the unit will cycle off. This will prevent a freeze up condition due to a long run time. Demand Slope range: 0 to -0.2

Temp. Comp.: Temperature compensation, utilized when the slope feature is turned on. It prevents the system from seeing the

slope temperature curve until a determined temperature is reached. Once that temperature has been reached then the system will examine the curve and shut down if

necessary. Temp. Comp. Range: -10 to 22°F

Temperature Offset: A function that allows temperature adjustment to the operator. Adjustable from 1-9 and 5 being neutral/no change, Lower than 5= colder and greater than 5=warmer

Transducer: An electronic control used to measure the cylinder pressure for mix pump operation.

U.I./ User Interface: The board that lies directly behind the membrane switch on the front panel. This board houses the LED screen that displays the menus and operations. The membrane switch is connected to this board via a ribbon cable. This board also has its own software.
