FREQUENCY CONTROL 2. OVER CURRENT PROTECTION 1) AC current peak control DC over current detection, AC over current detection. To protect against over current due to sudden change in load, the compressor is stopped if 24A DC is exceeded in the DC section. If the set value of AC current is exceeded in the AC section, the compressor is stopped. 90 seconds after the compressor has been stopped, another starting try will be made. Three retries are allowed. On the fourth retry, a complete stop request signal is sent to the indoor unit, and the outdoor unit will remain stopped until the indoor operation is stopped. DC over current is detected by the power module. AC over current is detected by CT1, on the outdoor PWB. Cooling mode 13.6A Heating mode 13.6A 2) Prevention control of outdoor heat exchanger overheating If the temperature of the outdoor heat exchanger exceeds the overheating prevention line 1 or 2 during cooling, the operating frequency is lowered by approximately 5 to 15Hz. After that, the frequency is lowered approximately 5Hz once every 60 seconds or approximately 15Hz once every 120 seconds. When the temperature of the outdoor heat exchanger goes below the overheating prevention clear line, the frequency is raised by approximately 5Hz once every 60 seconds, and normal operation is restored. If the frequency is lowered to minimum frequency without the temperature of the outdoor heat exchanger decreasing and this condition lasts for 1 minute, the compressor will be stopped. Overheating Prevention line 1 55C Overheating Prevention line 2 57C Overheating Prevention clear line 54C Cooling mode 16.0A 3. COMPRESSOR PROTECTION CONTROL If the temperature of the compressor exceeds 113C, the compressor is stopped. In this case, the outdoor fan is not stopped until the temperature of compressor drops below 99C. In 90 seconds after the compressor is stopped, if the temperature is below 90C, another starting try will be made. Three retries are allowed. On the fourth retry, a complete stop request signal is sent to the indoor unit, and the outdoor unit will remain stopped until the indoor operation is stopped. Lower 5Hz once every 60 seconds Lower 15Hz once every 120 seconds 4. POWER TRANSISTOR MODULE PROTECTION 3) Prevention control of compressor overheating If the temperature of the compressor exceeds approximately 108 C, the operating frequency is lowered approximately 5Hz. After that, the frequency is lowered approximately 5Hz once every 60 seconds. When the compressor temperature drops below approximately 108C, the frequency is raised approximately 5Hz once every 60 seconds, and normal operation is restored. If the frequency is lowered to minimum frequency without the temperature of the compressor decreasing, and this condition lasts for 1 minute, the compressor will be stopped. If the temperature of the heat-sink exceeds 90C, the compressor is stopped. In this case, the outdoor fan does not stop, and when the temperature of the heat-sink decreases to 80C 180 seconds after operation is stopped, another try will be made. Three retries are allowed. On the fourth retry, a complete stop request signal is sent to the indoor unit, and the outdoor unit will remain stopped until reset is performed. At this time, the 3-minutes delay for control of the outdoor unit will not function; therefore, do not cancel by removing the plug and cutting the power. Also if the temperature of the heat-sink exceeds 100C, a complete stop request signal is sent to the indoor unit, and the outdoor unit will remain stopped until reset is performed. At this time, the 3-minutes delay for control of the outdoor unit will not function; therefore, do not cancel by removing the plug and cutting the power. 4) Prevention control of indoor heat exchanger overheating Two minutes after room several decrease If the temperature of any of indoor heat exchangers exceeds the overheating prevention line 1 or 2 during heating, the operating frequency is lowered to minimum frequency. When the temperature of all of indoor heat exchangers go below the overheating prevention line 1, the frequency is raised by approximately 5Hz once every 60 seconds, and normal operation is restored. If the condition that the frequency is minimum lasts for 2 minutes, the compressor will be stopped. 5. SERIAL SIGNALS Serial signals consist of all 96-bit signals. If the condition as outdoor unit unable to receive a serial signal from the indoor unit continues for 30 seconds, it closes the expansion valve which corresponds to the room which can not be communicated. If all indoor units can not communicate with the outdoor unit, the compressor is stopped. <when normal > If the temperature of any of indoor heat exchangers exceeds the overheating prevention line 1 or 2 during heating, the operating frequency is lowered by approximately 5 to 15Hz. After that, the frequency is lowered approximately 5Hz once every 60 seconds or approximately 15Hz once every 90 seconds. When the temperature of all of indoor heat exchangers go below the overheating prevention line 1, the frequency is raised by approximately 5Hz once every 60 seconds, and normal operation is restored. If the condition that the frequency is minimum lasts for 2 minutes, the compressor will be stopped. 54ºC (59ºC) 47ºC (60ºC) 44ºC (57ºC) Overheating prevention line 1 900 2100 6. THERMISTOR OPEN OR SHORT When compressor, heat exchanger, outdoor thermistor, suction thermistor (CN8A) are in OPEN or SHORT condition, even if they are in the condition which an operation signal is transmitted from indoors, the compressor will not start. If any suction thermistors (CN8C) become OPEN or SHORT resistance, the protective procedure will work only for the cycle corresponding to the malfunctioning suction thermistor. Overheating prevention line 2 57ºC (62ºC) 7. MISWIRING CHECK “Mis-wiring check” is conducted by detecting the indoor heat exchanger temp. For example, when the expansion valve for only room A is open, and the wiring is correct, the indoor heat exchanger temp for room A will reduce. If the wiring is incorrect, the indoor heat exchanger temp for a different room will reduce. 51ºC (57ºC) 48ºC (54ºC) When ON (When OFF) Heating mode 16.0A 8. SAFETY TIME 5200 When the unit is operated by the remote control after the breaker is turned on, the safety device of the compressor will work and the compressor will not operate for 90 seconds. 7200 2–2 AEX2M14LR 9. PUMP DOWN SWITCH More than 20 min. When the PUMP DOWN SWITCH (SW1) is pressed for 5 seconds or more, the total A/C system will start its TEST RUN automatically and the compressor frequency will be 48.3 Hz. When operating only the outdoor unit (cooling 48.3 Hz fixed mode) To make only the outdoor unit run in cooling mode, and apply a voltage of 230 V AC to N and L on the terminal board and push the pump down switch. (SW1) (Avoid operating the outdoor unit alone for long periods of time.) Heating operation start 10. CONTROL OF COMPRESSOR OR AND EXPANSION VALVE For 90 seconds after turning on the AC power, the compressor will not be activated even if indoor units request the compressor to do so. If the compressor receives a request from one or more indoor units after 90 seconds have passed, it will be turned on and the expansion valve corresponding to the requesting indoor unit will be opened. When the indoor unit of a room requests for the cooling operation to the outdoor unit and it runs responding to the request, requests for the heating can't be accepted if the indoor units in other rooms send individual requests. If the indoor unit in another room sends a request for the heating operation, the operation lamp and timer lamp of the indoor unit in that room start flashing in turn to inform that the unit is in the standby mode. If the operation in one room is stopped while the indoor unit in another room is in the stand-by mode, the operation mode requested by the indoor unit which is now in the stand-by mode will be accepted. At this time, the compressor will be temporarily stopped to switch the four- way valve and restart after 90 seconds. During the cooling or dry operation, the expansion valve corresponding to the indoor unit that is not running is closed. Therefore, the refrigerant will not flow into those units However, if the heating operation is in progress, it is possible that it flows into indoor units which are out of operation depending on the cycle conditions. As a result, the indoor exchanger may be heated up even if it is not activated. This is not abnormal. When the operations in all rooms are stopped, the compressor is off and the expansion valves in all rooms are fully opened. More than 20 min. More than 20 min. Defrosting Defrosting Max. 10 min. Max. 10 min. 3) During defrosting When defrosting begins, the compressor stops. Approximately 1 minutes later, the compressor reactivates in the refrigeration cycle, and the outdoor heat exchanger is defrosted. Each mode is as follows: The outdoor fan is s topped The operating frequency is as shown in the table below. The indoor fan is s topped. All expansion valve are open. for 5 minutes 3900 rpm after that 3700 rpm 4) Defrost stop When defrosting time exceeds 10 minutes When the temperature of the outdoor heat exchanger rises above approximately 15C Defrost stop is determined by either of the above conditions, and the compressor is stopped. At the same time, the outdoor fan go ON. The compressor is reactivated in the heating cycle 1 minutes after it was stopped, and normal control resumes. 11. DEFROST OPERATION 12. Power factor module Output voltage 1) Overview If a voltage error over 450V is detected at power factor module output voltage, the compressor is stopped for 3 minutes. In this case, the outdoor fan does not stop for 3 minutes, and another try will be made. Three retries are allowed. On the fourth retry, a complete stop request signal is sent to the indoor unit, and the outdoor unit will remain stopped until reset is performed. At this time, the 3 minutes delay for control of the outdoor unit will not function; therefore, do not cancel by removing the plug and cutting the power. Defrosting begins during heating if the conditions for compressor operation time and outdoor heat exchanger temperature are met. When defrosting begins, the indoor and outdoor fans stop. Defrosting stops when the temperature of the outdoor heat exchanger goes above approximately 15C or defrosting time exceeds 10 minutes. Defrost mask time Heating begins Defrost mask time Defrost mask time 13. Winter cool Cooling operation is available during the winter season by the built in winter cool function. Lower limit of outdoor temperature range is -10C DB. Defrosting Max. 10 min. Defrosting Max. 10 min. When the outside air temperature is low, the outdoor unit fan operates at slower speed. NOTE: Built-in protect drive may work when outdoor temperature falls below 21C DB, depending on conditions. 2) Defrosting If the compressor operation time is more than 20 minutes in the heating mode and the outdoor air temperature and outdoor heat exchange temperature satisfy the defrosting conditions, the defrosting operation is started. When the defrosting operation is started, the indoor fan starts to run intermittently. When the outdoor heat exchanger temperature reaches approx. 15C or above or when the defrosting time exceeds 10minutes, the defrosting operation is quit. 2–3 AEX2M14LR [3] ACTIVE FILTER CIRCUIT This circuit uses Active Filter Module and IPM as the figure below for the high efficiency operation of compressor. Active Filter Choke coil Rectification circuit AC + Noise filter circuit Sine wave current ON/OFF Voltage raise signal Compressor Driving signal Compressor IPM Positional detection IPM Control source Control source IC1 1. Active Filter In the case the direct current is obtained by the diode bridge and smooth capacitor from the commercial power source, the current wave shape will be the pulse shape at the peak of the voltage wave shape as shown in the figure below. For this reason, the harmonic current will be generated and at the same time the power factor will be deteriorated. While monitoring the AC input voltage in the control circuit, in order to be the same phase and wave shape as this voltage wave shape, IGBT is made ON/OFF by the carrier frequency of approximately 20 kHz. By adoption of this Active Filter, the current wave shape can be made to the sine wave synchronized to the commercial power source and the power factor can be made to almost 99%. As a result of this, reactor can be disused. Active Filter works for the improvement of power factor and as the countermeasures for the harmonic current. Power-supply voltage (50Hz) Current waveform (Before) Current waveform (Active Filter) 2. Active Filter Voltage Raise Circuit The IGBT in the figure below is the switching transistor of the Active Filter. By adding ON signal to the gate of IGBT from the control IC, IGBT turns ON and the collector current Ic flows. This current flows from the + side of the diode bridge DB to the Choke coil, the - side of the diode bridge DB through IGBT from the Choke coil L. At this time, energy is stored in the choke coil L. Next, when gate signal of IGBT turned OFF, IGBT will be turned OFF and the energy stored in L during the ON time of IGBT will be discharged through the diode D, electrolytic capacitor C, load, primary side and the + side of DB. Assuming the input voltage of Active Filter (voltage between + and - of DB) as Ei, the output voltage (voltage at the both ends of smooth capacitor) as Vo, switching cycle of IGBT as T and ON time of IGBT as ton, the voltage between collector emitter of IGBT Vs will be as follows; Vs= 0 (during ON of IGBT: ton) Vs= Vo (during OFF of IGBT: T-ton) Here, assuming no loss in L and IGBT, average value of Vs turns equal to Ei, Ei = (T-ton)/T x Vo Therefore Vo = T/(T-ton) x Ei As ton is a smaller value than T, output voltage Vo will be higher than input voltage Ei. 2–4 AEX2M14LR L + DB D Control Ei Vs IC Vo + RL C IGBT - L1 (+) L2 P (-) Io PFC control 1 2 3 4 5 6 BCN13 Active Filter Circuit 3. Active Filter Driving Electronics Circuit At the operation of compressor, the microcomputer (IC1), as the 50th pin gets “H”, will turn the transistor Q4 ON through the transistor Q3. By this, 18V is supplied to the 3rd pin of connector BCN13 of the Active Filter and the Active Filter will be turned ON. 4. Protection Circuit of Active Filter In order to prevent from the destruction of Active Filter due to the excessive over output voltage of Active Filter, the Active Filter will be turned OFF immediately at the abnormal output voltage by monitoring the output voltage. At the same time, the operation of compressor will be stopped. Detection circuit of the abnormal voltage detects the abnormal voltage by inputting the output voltage of Active Filter to the 4th pin of comparator IC (IC5) at the divided voltage by the resistors (R31, R32 and R33) and comparing with reference voltage. When the output voltage of Active Filter reaches 450V or higher, the 4th pin of IC5 will be higher than the reference voltage at the 5th pin, the output of comparator will be reversed (HL), the L signal will be entered at the 52nd. pin of microcomputer (IC1) and the operation of the Active Filter will be stopped. 18V 5V R36 1M IC1 52 3 2 12 4 + 5 0V R33 270KF R35 34.8KF R32 270KF IC5 C57 0.1u 50V R34 9.53KF C56 0.1u 50V 0V 0V 2–5 R31 4.64KF 0V DC Voltage AEX2M14LR [4] EXPLANATION OF IPM DRIVE CIRCUIT The power supply for the IPM drive, and the shunt resistor for over current detection, etc., are provided out of the IPM (in control PWB). 1. IPM drive power supply circuit The power supply for driving the upper-phase IGBT (HU, HV, HW) drive employs a Bootstrap system. The 15-V power supply for the lower-phase IC is provided by the control printed circuit board (PWB). 1. Brief explanation of Bootstrap system (single power drive system) To supply power to the upper-phase IC, the microcomputer (IC1) turns ON the lower-phase IGBT (LU, LV, LW). It results in a charging current that flows through the electrolytic capacitor in each upper-phase IC input and charges the Bootstrap capacitor up to 15V voltage. The power supply for the subsequent stages is stored when the lower-phase IGBT is ON in common drive control of the compressor.

DC over current detection circuit When a current about 24A or higher flows through the shunt resistor (R100) on IPM printed circuit board (PWB), the voltage on this resistor is input to IPM CIN pin (16). Then, the gate voltage of the lower-phase IGBT (LU, LV, LW) inside the IPM turns OFF to cut the over current off. At the same time, an L output which lasts about 1.8 ms is generated from IPM Fo pin (18), and it results in an L level input to over current detection input pin (53) of the microcomputer (IC1) and then turns OFF the compressor driving signal output (IC1 from pins (65) to (70)) to the IGBT gate.

The motor's induced voltage waveform is input to the comparator in the form of PWM-switched pulse, and a position detection signal is generated as a reference voltage which is equal to 1/2 of 370 VDC. However, since there is no induced voltage waveform when the PWM waveform is OFF, the microcomputer works in an internal processing so that detection is enabled only when it is ON. Based on the position signal detected, actual PWM waveform output timing is determined. Since it does not use a filter circuit, the accuracy of detection. The microcomputer works in an internal processing to eliminate spiky voltage during the regenerative process. Furthermore, even if the induced voltage is low, position detection is still possible, and it allows sensor-less operation at low rotation speed in the initial stage of operation. These reduce the starting current and improve reliability of IPM. Terminal voltage waveform Reference voltage (1/2 of DC voltage) Spiky voltage (cancelled) Comparator output waveform (Position signal waveform) 4. 180 energizing control This is the control system to moderate the speed by the current phase difference for higher efficiency and lower noise of the compressor. The current phase difference control is the control system paid attention to the interrelation between efficiency and phase gap generated by the applied voltage of motor and current in the coil of motor as shown in the figure below. Motor voltage Motor current Efficiency This control is the forced magnetization system independent of the location of rotor, detecting the phase difference between driving voltage phase and line current phase flowing in motor coil, and controls the modulation rate data to get the phase difference at the best efficiency. Difference of current and voltage peak Ტ Best timing Ჷ( Უ Voltage /Current phase difference Concept chart of the current phase difference control 5. DC Current Detection Sensor Circuit Control of current phase difference is made by reading in the phase difference generated at the both edges of shunt registor (R100) by the compressor electrifying current on the PWB through the Op-amp (IC9) to the microcomputer. This is a control to modulate up to the phase with the best efficiency by comparing the phase of this input current, so called compressor electrifying current, with the compressor driving voltage. In the case that phase difference between motor voltage and current is large (current delay is large), the control will be made by lowering the compressor modulation rate data (compressor effective value).

(5)No abnormality found in above inspections(1)and(4). Inspection location/method CHECK METHOD CAUTION: CHECKING PRINTED CIRCUIT BOARDS (PWB) Non-insulated control circuit Do not touch the cabinet or bring metal parts into contact with the cabinet. The GND terminals of the low-voltage circuits (control circuits for microcomputer and thermistors and drive circuits for expansion valve and relays) on the control printed circuit board (PWB) are connected to the compressor drive power supply (370-VDC negative terminal). Therefore, exercise most caution to prevent electric shock. Danger!! Do not connect the grounding wire. If a measuring instrument used for the test is grounded, its chassis (ground) has the same electric potential as the 0-V probe. Since noninsulated circuits have the following voltage potential difference from the ground, connection of the grounding wire results in a short-circuit between the 0-V line and the ground, thus allowing an excessive current to flow to the tester to cause damage. If the sheaths of the thermistor lead wires or expansion valve lead wires inside the outdoor unit become damaged due to pinching by the front panel or other metal parts or contacting a pipe, a high voltage can flow and destroy the circuits. To prevent these problems, carefully conduct assembly work. Reason The oscilloscope (chassis ground) has the same electric potential as the 0-V probe. The entire electronic control section of the outdoor unit has a voltage potential difference from the ground. When the oscilloscope is setup, the 0-V line and the ground voltage (ground) will be short circuited, resulting in an excessive current flow to cause damage to the oscilloscope or indoor electric circuits. CAUTION: when attaching or removing the board When operating only the outdoor unit (cooling 48.3 Hz fixed mode) to make the outdoor unit run in cooling mode, apply a voltage of 220 ~ 240V AC to L and N on the terminal board and push the pump down switch (SW1).
