Startup control Temperature of the indoor heat exchanger The main relay remains off during the first 45 seconds (first safety Preset Fan speed 35ºC time) immediately after the power cord is plugged into an AC outlet in 32ºC order to disable outdoor unit operation and protect outdoor unit electric The indoor fan operates at low speed. - Page 14 GSXP12HRN * During Cooling / Dry • Power ON/OFF • Automatic operation mode setting Timer set time • Swing louver Room temperature • Plasmacluster operation mode 1ºC Setting not memorized hour • Timer setting Timer operation starts Stops • Full power setting 1.8.
- Page 15 Heating operation ing frequency and operating status, the operating frequency is decreased by about 4 to 15 Hz. Then, this operation is repeated every GS-XP12HR-N Approx. 6.4 A Approx. 7.5 A 60 seconds until the temperature of the indoor unit heat exchanger 2.6.
- Page 16 GSXP12HRN 3. Explanation of cluster circuit The cluster unit generates cluster ions, which are circulated throughout the room by the air flow created by the blower fan (indoor unit fan motor) in the air conditioner unit. 1) When microcomputer output turns "H," the IC6 output changes to "Lo," turning ON the SSR and applying 230 V to the cluster unit for the genera- tion of cluster ions (positive and negative ions).
- Page 17 GSXP12HRN When the IGBT is ON, an electric current flows to the IGBT via the reactor (L5), (L6) and diode bridge (DB2). When the IGBT turns OFF, the energy stored while the IGBT was ON is charged to the voltage doubler capacitor via the diode bridge (DB1). As such, by varying the ON/OFF duty of the IGBT, the output voltage is varied.

GSXP12HRN 4.3. PAM protection circuit To prevent excessive voltage of PAM output from (Overvoltage detection) damaging the IPM and electrolytic capacitor as well as the control printed circuit board (PCB), this circuit monitors the PAM output voltage and turns off the R112 R114 255K... - Page 19 GSXP12HRN 5.1. IPM drive power supply circuit The power supply for the upper-phase IGBT (HU, HV, HW) drive employs a bootstrap system, and provides power to the upper-phase IC. The 15-V power supply for the lower-phase IC is provided by the control printed circuit board (PCB). 5.1.1 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).
- Page 20 GSXP12HRN 5.1.2 DC overcurrent detection circuit When a current of about 25 A or higher flows through the shunt resistance (R49) on the control printed circuit board (PCB), the voltage at this resis- tance is input to IPM CIN pin (26). Then, the gate voltage of the lower-phase IGBT (LU, LV, LW) inside the IPM turns OFF to cut off the overcurrent. At the same time, an L output of about 1.8 ms is generated from IPM Fo pin (24), and this results in an L input to overcurrent detection input pin (34) of the microcomputer (IC1) and turns OFF the PWM signal output (IC1 pins (51) through (56)) to the IGBT gate.
- Page 21 GSXP12HRN The microcomputer performs internal processing to cancel spike voltage during the regenerative process. Furthermore, even if the induced voltage is low, position detection is still possible, thus allowing sensor-less operation at low rotation speed in the ini- tial stage of operation. This reduces the starting current and improves the IPM reliability. Terminal voltage waveform Reference voltage (1/2 of DC voltage)
