Afterwards, C is charged by the fault current, at the same time T 1 is turned on, and then R 1 and R 2 are put into the fault circuit to limit the rise of the fault current. In the following sections, the discharging of the commutation capacitor and the input of the current-limiting resistors will be introduced in detail.
faults. During a fault, excessive current—called fault current— flows through the electrical system often resulting in a failure of one section of that system by causing a tripped circuit breaker or a blown fuse. A fault current limiter (FCL) limits the amount of current flow-ing through the system and allows for the continual, uninterruptedCarrier furnace code 13 is a limit circuit lockout error, which means that the furnace has tripped its limit switch and will not reset until it has cooled down. This can be caused by a variety of issues, such as a clogged air filter, a blocked vent or flue, or a malfunctioning blower motor.If no air is reaching the burner, it cannot combust and may enter lockout mode. This occurs most often because of a blocked or covered air vent. Snow and debris may be cutting off your furnace oxygen supply. Dirty air filters may also be responsible.
