7.2 Circuit breaker failure protection

All AQ-101 variants include a selective circuit breaker failure (CBFP) function, which can be enabled

through the DIP switch settings (please refer to the "DIP switch settings" chapter for more information).

When enabled, the CBFP function activates when the tripped breaker fails to operate, or if the unit

detects the presence of light after a set operating time. Please note that if the unit is set to operate on

both arc light and overcurrent, both conditions must persist to activate the CBFP function. The CBFP

function can be set to operate either on a 100-ms or a 150-ms delay (again, please refer to the "DIP

switch settings" chapter for more information).
