This is not abnormal. 1.7. MISWIRING CHECK When the operations in all rooms are stopped, the compressor is stopped,the expansion valves in all rooms are fully opened. "Miswiring check" is conducted by detecting the indoor heat exchanger indoor heat exchanger temp. 1.11.

Power factor module Output voltage 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 minute delay for control of the outdoor unit will not function; therefore, do not cancel by removing the plug and cutting the power. . 2–4 AEXM24HR 2. Active Filter Circuit This circuit uses active filter and IPM as the figure below for the high efficiency operation of compressor. Active filter Choke coil Rectification circuit AC + Noise filter circuit Comp ressor IPM Sine wave current ON/OFF Voltage raise signal Compressor Driving signal Control source Positional detection IPM Control source IC1 2.1. 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 (50 Hz) Current waveform (Before) Current waveform (Active filter) 2.2. 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. 2–5 AEXM24HR L + DB D Control Ei + Vs IC RL Vo C IGBT - L1 (+) L2 P (-) Io PFC control 1 2 3 4 5 6 BCN13 Active Filter Circuit 2.3. 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. 2.4. Protection Circuit of Active Filter In order to prevent from the destruction of active filter due to the excessive over or under 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 2nd and 4th pins 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 (H-L), 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 R31 4.64KF C56 0.1u 50V 0V DC Voltage 0V 0V 2.5. Explanation of IPM drive circuit The power supply for the IPM drive, and the shunt resistance for over current detection, etc., are provided out of the IPM (in control PWB). 2.5.1 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). 2–6 AEXM24HR 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 overcurrent detection circuit When a current about 32A or higher flows through the shunt resistance (R100) on IPM printed circuit board (PWB), the voltage on this resistance 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 overcurrent 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 overcurrent 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 2–7 AEXM24HR 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) 2.6.2 180° 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 Efficiency Motor current Best timing Ტ Ჷ( Difference of current and voltage peak Უ Voltage /Current phase difference Concept chart of the current phase difference control 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. 2.7. 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 register (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). 2–8 AEXM24HR IPM FUSE 101 250V 20A P S FC1 C121 630v 0.33Ǵ TU TV TW C R N CIN C119 1000p R201 100KF ZD101 R113 18KF R100 0.015 5V Z D8 15V 8 1 IC1 C96 1000P Y R200 1K C97 0.1μ 4 2 + 3 IC9 0V Inverter current detection circuit R202 20KF R203 2.0KF 5V R204 200KF R205 200KF 0V 2–9 Y Z CHAPTER 3.

Remedy CHECK METHOD (OUTDOOR) CAUTION IN CHECKING PRINTED CIRCUIT BOARDS (PWB) Non-insulated control circuit 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 utmost caution to prevent electric shock. If a measuring instrument used for the test is grounded, its chassis (ground) has the same electric potential as the 0-V probe. Since non-insulated 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. Do not touch the cabinet or bring metal parts into contact with the cabinet. Danger!! Do not connect the grounding wire. 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 set up, 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. 3–6 Figure 1 Cautions when attaching or removing the board When operating only the outdoor unit (cooling 55 Hz fixed mode) To make only the outdoor unit run in cooling mode, and apply a voltage of 220 ~ 240V AC to L and N on the terminal board and push the PUMP DOWN SWITCH (SW1).
