Introduction Specifications and Overview

Sixth Sense Technology

6th Sense software makes an estimation of the actual food temperature inside the refrigerator and freezer compartment and adjusts cooling to allow the food packages to return their initial temperature faster during pull down, door openings, or heavy food load.

6th Sense algorithm runs in both FC and RC and each contains 3 routines: Trigger,

Package Estimator, and Defrost Manager.

• Trigger routine is executed every 2.5 seconds while Package Estimator and

Defrost Manager are executed every 10 seconds. The trigger routine is divided into two subroutines: door monitoring and temperature monitoring.

Trigger parameters and performance parameters reside in the UI board, the actual 6 th sense algorithm resides in Gemini Flash board.

• Package Estimator routine computes an estimation of food in FC and RC according to Thermistor reading and door status. Package estimator is run when the User Interface sends the required parameters to Gemini flash and sets the

6th Sense Enable bit to true. If 6th Sense is needed, it will call for additional cooling by turning on compressor, damper and evaporator fan.

• Defrost manager is composed of two main states: Normal and 6th Sense.

When 6th Sense routine is active, defrost will be inhibited based on the control parameters settings to allow food temperature recovery.

Door Open Alarm

The Door Ajar Alarm feature sounds an alarm when the refrigerator or freezer door is open for 5 minutes and the product cooling is turned on. The alarm will repeat every 2 minutes. Close both doors to turn it off. The feature then resets and will reactivate when either door is left open again for 5 minutes.

Details :

When a door is open for 5 minutes and the cooling function is on:

The Door Open Icon and the normal screen is displayed.

The Door Open chime is sounded 3 times.

The Door Open Icon appears and blinks 7 times and then becomes constant.

If a door is left open, every 2 minutes, the Door Open chime sounds 3 times, the Door Open icon blinks 7 times and ten becomes constant.

Note: since inactivity to sleep is also two minutes, the door ajar situation shall overwrite the sleep mode. In other words, the UI will never go to the sleep mode if it is in the Door Ajar mode.

When the door ajar alert condition is met (door open for 5 min), pressing any button on the control panel at any time will turn off the Door Open Alert

Starting Device Operation

The starting device is an assembly consisting of an overload (1) and a PTC relay (2). The PTC relay is composed of a semi conductive substance formed in the shape of a disk (2). The disk is connected in series with the run and start terminals which in turn connect to the run and start windings. The resistance of the disk material is relatively low at room temperature.

When voltage is applied and current flows to the compressor windings, the current flowing to the start winding heats the disk material. As the temperature of the disk increases, the resistance of the disk increases rapidly and limits current flow to the start winding. At the same time current flow through the disk is decreasing, the effects of current flow through the run capacitor increases.

This change in current and capacitance seen by the start winding helps start the compressor and allows the start winding to remain in the circuit once the compressor is running.

Note: Do not disassemble the PTC device. The PTC device (2) was opened to show the interior construction and to assist in explaining the theory of operation.

Checking the PTC: The easiest way to check the PTC device is to replace it with a known good one. If a new PTC device is not available, a resistance check can be made.

1. Unplug the refrigerator

2. Disconnect the starting device from the compressor.

3. Unplug the run capacitor form the module.

4. Connect an Ohmmeter across the L and S terminals.

5. If the PTC is at ambient temperature,

70 – 80 degrees F., the approximate resistance should be between 3 and 10

OHMs. An infinite reading indicates the

PTC device is open.
