The line frequency signal can’t go through the high-pass filter (UM40D), so OP_FUSE (11) will be active high (b) If inverter fuse (FUA4) is broken, then the waveform of Vinv3 will be PWM waveform. This high frequency signal can go through high-pass filter (UM40D) and OP_FUSE (11) will be active low.

(a) POWER_RDY (10) will send out pulse to reset CM129. And then CM129 will be charged again by 5V through RM215. UC33-3 will keep high level. If POWER_RDY (10) doesn’t send out pulse for a specific period (for example: MCU is crash) then UC33-3 will be low. (b) Test JUMP: JPM3: If JPM3 is shorted, then UC33-3 will be low or UC33-3 will keep high during normal operation.

(a) THS1-1 is connected to the thermal switch located at heatsink of bypass SCR. If the thermal switch is open due to over-temperature, the driver will be off (b) MCU can detect over-temperature of bypass SCR through CPU-P91 (91) (c) The bypass SCR driver signal will come from MCU or US4 according to the signal “TO US36-P4”. (d) “TO US36-P4” is the output of MCU watchdog. If MCU is operating normally then “TO US36-P4” will be high and the bypass driver signal will come from BYPSTS (33). If MCU is not operating normally, “TO US36-P4” will be low and then the bypass driver signal will come from US4 (e) US4 is a 37kHz self-oscillator that can provide driver signal for bypass SCR. (f) RS47/DS13/CS41 is used to disable the output of US4 during initialization of auxiliary power (g) The output of driver signal from US4 is also limited by TOBYP_I (105) signal (h) US15B-P3 is the signal used to send out To bypass signal on parallel port no matter the bypass SCR is driven by MCU or US4 Refer to “Watchdog For System MCU” for “TO US36-P4” signal.

(a) SYS_RDY (29) will send out pulse to reset CS27. And then CS27 will be charged again by 5V through RS1. “TO US36-P4” will keep high level. If SYS_RDY (29) doesn’t send out pulse for a specific period (for example: MCU is crash) then “TO US36-P4” will be low. (b) Test JUMP: JPS6: If JPS6 is shorted, then “TO US36-P4” will be low or “TO US36-P4” will keep high during normal operation.
