Specified temperature

in the refrigerator

Notice

The specified temperature in the above table, from data when measured in unload state and at 1/3 H inside the room, is only to describe the temperature at each step generally. The actual temperature depends upon the surrounding conditions and the loading state.

Set Power-Freezing and Power-Refrigerating by pushing the separate button. On pushing the button for power-freezing and for power-refrigerating, selection/cancellation (lamp on/lamp off) is selected in order. In spite of the selection of power-freezing or power-refrigerating, the temperature setting in the Freezer and Refrigerator is not changed. With the selection of Power-Freezing or Power-Refrigerating, you can change the temperature setting of the freezer and refrigerator.

1. Power-Freezing Function

1) On the selection of Power-Freezing, COMP and F-Fan operates continuously for 2 hours and 30 minutes.

2) In spite of the Power-Freezing operation, the refrigerator operates according to the current setting.

3) On the finish of Power-Freezing (after continuous operation of COMP and F-Fan for 2 hours and 30 minutes), lamp indicating Power-Freezing turns off automatically and the freezer operates according to the temperature setting.

2. Power-Refrigerating Function

1) On the selection of Power-Refrigerating, COMP and R-Fan operates continuously till the temperature inside the refrigerator becomes about -4.0 .

2) After the temperature inside the refrigerator is to be -4.0 , Power-Refrigerating function stops after 1hour ÒCOLDERÓ operation according to the internal function regardless of the current setting.

3) When the temperature inside the refrigerator does not become -4.0 in spite of the selection of PowerRefrigerating function and the continuous operation of COMP and R-Fan for 2 hours and 30 minutes, PowerRefrigerating stops.

4) On the finish of Power-Refrigerating (after continuous operation for 2 hours and 30 minutes or approach to

-4.0 and then, ÒCOLDERÓ operation for 1 hour), lamp indicating Power-Refrigerating turns off automatically and the refrigerator operates according to the temperature setting.

5) If the current setting is ÒWARMER-MEDIUMÓ (2nd step) or ÒWARMERÓ (1st step), the lamp indicating Power-Refrigerating turns off after 1-hour ÒCOLDERÓ operation, but 1-hour ÒMEDIUMÓ operation continues

according to the internal function. At this time, if the setting is changed, immediately cancel the ÒMEDIUMÓ operation and perform the operation according to the changed setting condition.

6) If there is no change of setting during 1-hour ÒMEDIUMÓ operation, perform the operation according to the temperature setting after ÒMEDIUMÓ operation stops.

3. Concurrent selection of Power-Freezing and Power-Refrigerating

1) Each function operates independently. It mean that COMP and F-Fan operate continuously by PowerFreezing regardless of Power-Refrigerating function and COMP and R-Fan by Power-Refrigerating function are continuously operated till the temperature inside the refrigerator becomes -4.0 .

7-3. Power-Freezing and Power-Refrigerating

Notice

If the temperature inside the freezer is above -10 and that inside the refrigerator is above 10 such as the case of the first POWER ON, Power-Freezing and Power-Refrigerating will not work as you can expect. However, this is not the usual case and so, explanation is omitted here.

7-4. ALARM function

1. Button TOUCH sound (ÒDING-DONGÓ sound)

1) If you push each button on the CONTROL PANEL, ÒDING-DONGÓ sounds to confirm the push.

2) If you push two buttons at one time or if you do other wrong-doings, ÒDING-DONGÓ does not sound.

2. DOOR-OPEN alarm (ÒDING-DONGÓ sound)

1) After two minutes with the door of the freezer or the refrigerator opened, alarm sounds ten times.

2) If the door is still in open in spite of the first ten-time alarm, alarm continues 10 times per minute.

3) The alarm stops immediately when the door of the freezer or the refrigerator is closed.

4) If you select OFF for the alarm (for the model with alarm-off function) (Alarm-lamp out) or if you select OFF for the alarm while alarming, DOOR-OPEN alarm will stop although the door is in open.

5) In spite of the selection of OFF for the alarm, ÒDING-DONGÓ for BUTTON-TOUCH operates normally.

3. Forced-operation and Forced-defrost alarm (ÒBEEPÓ sound)

1) On the selection of Forced-operation and Forced-defrost, ÒBEEPÓ alarm will sound.

2) On the selection of Forced-operation, alarm will continue until the automatic cancellation (after 24-hour Forced-operation) or till the cancellation function is selected.

3) Also, alarm for Forced-defrost continues until the finish of Forced-defrost (including the pause time) or the selection of the cancellation.

7-5. Defrost function

1. On the first POWER ON, concurrent defrost for freezer and refrigerator operates after the accumulated operation time for COMP ON is above 4 hours.

2. Since then, defrost interval will vary from 6 hours to 48 hours according to the operation and the surrounding conditions.

3. After finish of the first defrost, PRE-COOL function operates for 20 minutes at the start of the defrost to minimize the temperature increase caused by the defrost. However, the PRECOOL function depends on the temperature inside the refrigerator at the start of the defrost.

4. If the temperature inside R-room is above 0 , PRE-COOL function operates, but if the temperature inside R-room is below 0 , PRE-COOL function does not operate. In case of F room, if the temperature is above -21 , PRE-COOL function operates and if below -21 , the function does not operated.

5. In the above 4, if the temperature of F-room is above -21 (PRE-COOL function condition), PRE-COOL function will be operated both at F and R-room regardless of the condition inside R-room. If the case is only about R-room, PRE-COOL function will be operated independently. It means that PRE-COOL function will be operated only in R-room when only R-room is in the condition for PRE-COOL.

7-6. TEST function

TEST function is for quality control of PCB and the product, in-process control, and SVC. After check of the function of the product by the selection of TEST S/W, POWER should be turned ON again to perform self-diagnostic function.

1. Forced-Operation function

1) If you select button on MAIN PCB one time, COMP operates immediately without 5-minute DELAY. So, attention should be paid because if you perform Forced-operation at the COMP-OFF time, OVER LOAD may occur.

2) On the selection of Forced-operation, ÒCOLDERÓ for the freezer and ÒCOLDER-MEDIUMÓ for the refrigerator are selected automatically, COMP and F-Fan are operated on continuous basis, and R-FAN in the refrigerator is controlled by ÒO(MEDIUM-COLDER)Ó setting.

3) Forced-operation is effective only for 24 hours. It means that, 24 hours after the start of Forced-operation, concurrent defrost in freezer and refrigerator is conducted automatically and normal operation starts according to the setting for freezer and refrigerator.

4) To cancel Forced-operation, turn ON again after POWER OFF (RESET) or select TEST CANCELLATION MODE as described in the below Ò3Ó.

5) On Forced-operation, alarm (0.5 seconds ON/0.5 seconds OFF) continues to the finish of Forced-operation. There is no cancellation way.

2. Forced-defrost function

1) If you push TEST button one more in Forced-operation state, Forced-operation is immediately canceled and defrost function operates in refrigerator.

2) At this time, BEEP alarm will sound for 3 seconds at the start and continues on 0.75 seconds ON/0.25 seconds OFF basis during R Forced-defrost operation.

3) If you allow the above R-defrost function to operate, normal operation will start after the finish of the defrost.

4) If you push TEST button one more in R Forced-defrost operation, concurrent defrost for R and F-room operates.

5) Also, BEEP alarm will sound for 3 seconds at the start of concurrent R and F-defrost and continues on 0.25 seconds ON/0.75 seconds OFF basis by the finish of concurrent R and F-defrost.

3. Test Cancellation Mode

1) If you push TEST button one more in concurrent R and F-defrost, concurrent defrost will stop and normal operation will start.

Notice

TEST function will operate STEP BY STEP and so, it is not possible to change from 1 STEP (Forcedoperation) to 4 STEP (TEST CANCELLATION MODE). You should go through all STEP to perform the desired function. It is preferred to POWER ON after OFF on operation of TEST function.

7-7. Self-Diagnosis Function

1. Self-Diagnosis Function on the first POWER-ON

1) On the first Power-on, lamps are ALL ON and self-diagnosis function operates internally.

2) If there is no fault on the self-diagnosis, DISPLAY will show the first normal state.

3) If there is any fault on the self-diagnosis, the relevant LED will flicker and alarm will sound.

4) ERROR (indicating fault) display by the self-diagnosis will continue till all the relevant problems is fixed or the self-diagnosis is canceled.

5) When the relevant problems is solved, DISPLAY will return to the normal MODE.

6) After fixation of refrigerator, power should be off and on again to check whether the fault is corrected.

7) So, if there is a need to check SENSOR OPEN & SHORT for A/S, sensor can be checked through the selfdiagnosis operation by power-off and on.

8) If there is any problem, the relevant DISPLAY is as follows.

7-8. Load state display function

1. If you push buttons for ÒPOWER-FREEZINGÓ and ÒPOWER-REFRIGERATINGÓ for 3 seconds during the normal operation, all the temperature-setting DISPLAY for the freezer and refrigerator will be on. At this time, if you withdraw finger from the buttons, the temperature-setting DISPLAY for the freezer and refrigerator will be ALL ON/OFF for about 2 seconds at 0.5-second interval. At this time, if you push button for the temperature-setting for the refrigeration during ON/OFF, load state display function will start (with ÒDING-DONGÓ alarm).

2. Load state display MODE shows the load that MICOM signal is outputted. But, it means the output of MICOM signal. It does not show whether the load is actually operated. It means that, in spite of DISPLAY showing the operation of load, there is a possibility of none-operation by fault in the actual load or in RELAY on PCB. So, this function can be practicable on A/S.

3. Display continues for 30 seconds. After 30 seconds, the former-setting state will start automatically.

4. The relevant DISPLAY showing load state are as follows.

2. Self-Diagnosis function during the normal operation

1) If you push buttons for ÒPOWER-FREEZINGÓ and ÒPOWER-REFRIGERATINGÓ simultaneously for about 3

seconds during the normal operation, ALL ON/OFF in the temperature-setting DISPLAY will continue for about 2 seconds at 0.5-second interval. If you push buttons for ÒPOWER-FREEZINGÓ and ÒPOWER-REFRIGERATINGÓ simultaneously for about 5 seconds, including 2 seconds for LED ON/OFF, self-diagnosis function is selected.

2) At this time, the refrigerator will return to the self-diagnosis operation with ÒDING-DONGÓ alarm.

3) While the self-diagnosis function is in operation, the self-diagnosis will be performed in order from

ÒCOLDERÓLED of the freezer with ALL ON of the temperature-setting display for the freezer and refrigerator .

4) On ERROR, display will continue for 30 seconds and then, the refrigerator will return to the normal

operation state regardless of fixation of the relevant component. (With ÒDING-DONGÓ alarm)

5) Button push cannot be inputted during the self-diagnosis operation.

6) Among the items of the self-diagnosis, ERROR CHECK of ICE-MAKER SENSOR and ICE-MAKER function

will be done only on the model with the ICE MAKER.

These functions are limited only to the MODEL that ice and water can be obtained without opening of DOOR. Among the functions of this ice dispenser, all functions are operated by the mechanical system except the regulation of CUBE RELAY for obtaining of cube ice and the regulation of light in the DISPENSER, which are regulated by MICOM.

1. Light ON/OFF function

1) If you push button for Light ON/OFF on DISPLAY, lamp in the DISPENSER will be ON/OFF. To prepare the case of using at night, lamp in the DISPNSER will be regulated through LIGHT RELAY on MAIN PCB according to button selection.

2) ON/OFF is toggled by 1 button and it is limited to the MODEL with DISPENSER (SR-S24FTA).

3) As a means of safety, it there is no OFF signal for 20 seconds after lamp selection, lamp turns off automatically.

4) To turn on the lamp again, push the buttons for lamp ON/OFF.

5) On the first POWER ON, OFF function will be operated.

2. CRUSHED ICE / CUBE ICE / OFF selection function

1) This function is to operate CRUSHED ICE/CUBE ICE/OFF in order by user selection on DISPLAY. By pushing one button, CRUSHED ICE CUBE ICE OFF CRUSHED ICE is selected in order.

2) On the first POWER ON, CRUSHED ICE is automatically selected.

3) On the selection of CRUSHED ICE, operate GERADE MOTOR to get CRUSHED ICE in the outside when ice is made in the ice maker and ice LEVER is operated.

4) On the selection of CUBE ICE, operate GERADE MOTOR and ICE SOLENOID to get CUBE ICE in the outside when ice is made in the ice maker and ice LEVER is operated.

5) If you turn off all display lamp for ÒCRUSHED ICEÓ and ÒCUBE ICEÓ by pushing button for ice, no ice is made because of stop of ICE MAKER function.

7-9. ICE DISPENSER and WATER DISPENSER function(SR-S24FTA)

(1) At the moment of selection of stop function, ice-making function stops, but on eject, return to

horizontality, and water-supply, stop state will be maintained after finish of water-supply.

(2) When OFF function is selected, ice-making function stops. If you push button to select CRUSHED ICE

or CUBE ICE, ICE-MAKER will continue to operate from the stop of ice-making. (This means that icemaking function does not operate from the first.)

(3) In spite of operation of OFF function, ice LEVER will operate normally. This is not the disorder. So, ice

left in the tray of the ice-maker can be used normally. On operation of ice LEVER, GERADE MOTOR will operate normally and CUBE ICE can be obtained. (On operation of OFF function, only CRUSHED ICE can be obtained.)

(4) If you want CUBE ICE from the ice left in the tray during OFF function operation, push the button to

select CUBE ICE, obtain the ice and then, operate OFF function again.

3. WATER DISPENSER function

1) This function is directly connected to city water and water can be obtained from WATER SOLENOID VALVE by pushing WATER LEVER. Since there is no function regulated by MICOM PCB, if there is any problem with water dispenser function, check solenoid, connector, and water-supply state.

Notice

With DOOR of freezer open, ice cannot be obtained. This is to prevent from dropping ice into floor when DOOR of freezer opens and ice LEVER is pushed. Contact point in DOOR S/W is used as sensor for opening state of DOOR of freezer. Water dispenser is operated normally regardless of opening of DOOR.

8-2. Power generator circuit part

This is a power generator circuit part to generate synchronous CLOCK for information transfer of MICOM internal degauss and calculate time. On change of spec. of RESONATOR, normal operation cannot be performed from the result of change of TIMMING system in MICOM.

8-3. RESET circuit part

RESET circuit is to operate overall PROGRAM in the primary state by initializing several parts including RAM in the internal of MICOM when power is supplied to MICOM as a result of power input or instant suspension of electric supply. When power is supplied, voltage at RESET Terminal becomes scores of

ÒLowÓstate, when compared to the voltage of Vcc (DC 5V) of MICOM. On the general operation

state,ÓHighÓ (Vcc voltage) state is maintained.

8-4. DOOR S/W sensing circuit

DOOR OPEN/CLOSE of F-room sensing is performed by connecting of CN30 to GROUND, supplying Vcc (DC 5V) to through resistance R404 (4.7 ) and supplying ÒLowÓ (0V) / ÓHighÓ(5V) to MICOM by DOOR OPEN/CLOSE of F-room. DOOR OPEN/CLOSE of R-room sensing is performed by connecting of CN31 to GROUND, supplying Vcc (DC 5V) to through resistance R403 (4.7 ) and supplying ÒLowÓ (0V) / ÓHighÓ(5V) to MICOM by DOOR OPEN/CLOSE of R-room. If there is any problem in DOOR S/W, Fan in the relevant room will not work and alarm function will operate. So, DOOR S/W should be checked if there is any problem on A/S. For FAN in the relevant room will stop on DOOR OPEN, if there is any problem in the contact point of S/W, MICOM will judge that DOOR is opened and stop FAN operation, although DOOR is closed.

8-5. Temperature sensing circuit

SENSOR works on the basis of the characteristics of THERMISTOR with temperature coefficient of negative resistance that resistance value decrease when temperature is High and resistance value increase when temperature is low. R306 ~ R310 and C302 ~ C306 are parts to prevent NOISE. They have no relation with temperature sensing. In case of F-SENSOR, when the voltage inputted to MICOM is considered to be Vf, Vf is (Rth Vcc) /(R303 + Rth). In this equation, Rth is the resistance value of THERMISTOR corresponding to temperature. See the conversion table of the resistance and voltage of sensor according to the temperature in the Reference No. 8 of this manual. Use the table on A/S because MICOM Terminal voltage is also described in the table.

8-6. KEY SCAN and DISPLAY circuit part

1. Running of KEY SCAN and DISPLAY

As shown in the following waveform of each part, ÒHighÓ output is sent in turn from MICOM PIN

#3 #4 #5 #6 #7 for 2 msec at 10msec interval using five Terminal of MICOM NO #3, 4, 5, 6, and 7.

This signal appears at OUTPUT Terminal through INPUT Terminal of IC05 (UDN2981 or UPA2981C).

At this time, PEAK TO PEAK voltage of square-wave is about 11 V (DC RMS 1.5 V) and output waveform

is as follows.

2. KEY SCAN

When GRID #1 waveform is outputted, this signal is supplied to the button for temperature-setting of freezing

room through resistance 10 . At this time, when you push button for freezing room, the signal becomes

decreased by R506 (6.8 ) and about 4.5 V of PEAK TO PEAK voltage is approved to MICOM. After supply

of about 4.5 V of PEAK TO PEAK voltage to MICOM, MICOM can judge that GRID #1 waveform is inputted

and then, change the temperature-setting for freezing room. Like this way, each GRID waveform is perceived.

8-7. LOAD OPERATION circuit part

When ÒHighÓ signal is supplied to INPUT of IC03 (ULN2003A) at MICOM PIN NO #22 (P15), IC comes to be turned on. At this time, if V12 (DC 12V) supplied to the lower COIL of COMP RELAY runs into GROUND through OUTPUT of IC03, magnetic field will occur at CORE and then make contact point ON. This approves 220 V to COMP LOAD to make COMP ON and, if MICOM PIN NO #22 becomes ÒLowÓ state, IC comes to be TURN OFF state to make current not running to COMP RELAY COIL, to make RELAY contact point OFF state, and then, finally to stop COMP.

Like the above BLOCK DIAGRAM, LINE of AC 220V is connected to RELAY for COMP and COMMON for HEATER RELAY, respectively. At this time, if RELAY is not operated, contact point is NC state and RDefroster HEATER RELAY is OFF state. So, LOAD maintains OFF state. If COMP becomes the conditions for operation and COMP RELAY is operated (move to contact point NO), COMP becomes closed-circuit and operated and makes power for both ends of F, R-Defroster HEATER OFF state. If F-Defroster HEATER comes to operate, power for both ends of COMP should be OFF.

Purpose of the application of the above circuit : to block all power for both ends of Defroster-HEATER on the operation of COMP and to block all power for both ends of COMP on F-Defroster HEATER.

Table of Temperature Change of Freezer ( : Relevant DIODE No. used)

Explanation of Example : In case there is a need to change temperature of Refrigerator , change the

temperature according to the following procedures.

Step 1 : Since D605 to D608 are used as DIODE for temperature change of Refrigerator,

check DIODE used at the relevant PCB and the current temperature. For example, when D605 and D608 are used, it means the change to + 1.0 when compared with the temperature limit described in the above Table.

Step 2 : Determine the temperature to be adjusted according to judgement with regard to

the request from customers. For example, if about 2.0 should be lowered,

Step 3 : Calculate the temperature ; since the current OPTION state is +1.0 as shown in

step 1 and 2.0 is to be lowered as shown in step 2, add 1.0 to - 2.0 as follows. (+ 1.0 ) + (-2.0 ) = -1.0

Step 4 : Find out the relevant DIODE No. in the table corresponding to the calculated

temperature. Since DIODE corresponding to -1.0 is D606, 2.0 can be lowered by removing two current DIODE, D605 and D608 and inserting D606.

MODEL OPTION

on PCB

8-10. PCB SUB AssÕy (INVERTER PCB)

1. EMI circuit

COMMON MODE NOISE is attenuated by CHOKE LFI, NORMAL MODE NOISE and D.C RESISTANCE.

2. Rectifier circuit

Holding voltage is converted to DC voltage by BRIDGE DIODE. It is ELECTROLYTIC CAPACITOR and composed of balance circuit

3. First starter circuit

The current converted to DC by C2is charged to C3through R3. When more than 35V is charged at C3, the first switching operation is initiated by sending the current to BASE of Q

through DAC R1and D5maintain

enough potential difference between EMITTER and COLLECTOR of TRQ

for easy first switching.

4. Switching circuit

Q2becomes ON by the current from DAC and then, the current goes through C6C7C5CH

TR(C E). The current sent to PT1is held at PT3and by this holding current, Q2maintains ON state. Switching circuit is consisted when OSC COIL becomes saturated by line current, counter-electromotive force occurs at PT

, electromotive force is held at PT2, and then, Q1comes to be operated.

5. Resonance output circuit

To make the life-span of fluorescent light bulb longer, supply the filament pre-heat current. Line current is running through filament C

RT1filament C5PT1.

Resistance value is increased at PT

by running of PTC pre-heat current.

When impedance of PT

is Higher than impedance of C7, the current runs toward C7and so, discharge voltage is permitted to both ends of lamp. And finally, discharge occurs at lamp as a result of resonance of L and C. After LAMP is ON, the resonance current runs through lamp RT

2C5

PT1.

6. Guard circuit

On abnormal operation of LAMP or abnormal operation of switching circuit, toward D7, more than 0.7 V of voltage is held at GATE of SCR and so, SCR operates to block power. When abnormal voltage or over-voltage is held at power part, FUSE at the primary power circuit is gone to block the power.
