(a)Fan C is located at the rear panel of the power module’s input EMI filter. Fan A and Fan B are both located at the heat-sink for bypass SCR.

(b)MCU controls fan C via FAN-C (17).

(c)MCU detects a fan C failure via (18).

(d)When in bypass mode, FAN_A (143) will be high to control fan A; fan B will be off. If fan A experiences a failure, fan B will turn on.

(e)MCU detects a fan A failure via FANLOCK_A (19).

(f)MCU detects a fan B failure via FANLOCK_B (48).
