What is System Reset
System reset involves turning off the system and then turning it back on, with the aim of restoring the system to its normal functioning or recovering previously lost function. This action is also called “Recycling”.
System reset is different from re-engaging a tripped Circuit Breaker (C/B). A circuit breaker (C/B) will “trip” when it detects too much electrical current in the circuit. This helps prevent overheating or short-circuit conditions in the wiring, which could cause further damage or even fire.
System Reset Guidelines
The system reset tasks are given in TSM chapter 24. These tasks provide guidelines for system reset due to electrical transient or intermittent failure.
If it is obvious that this “ECAM Alert or System Malfunction” is consecutive to an electrical power up or transient, then the reset may be performed according to the TSM guidelines for the affected computers.
If “ECAM Alert or System Malfunction” does not correspond to an electrical power up or transient, then the maintenance engineer will check the fault history and perform the TSM procedure if the ECAM alert associated with this computer has been triggered on previous flights. A reset can be performed if no ECAM alerts associated with this computer have been triggered on previous flights.
To do system reset:
- Set the related normal cockpit control to OFF, or open the related circuit breaker as specified in the reset procedure.
- Wait 3 seconds if a normal cockpit control is used, or 5 seconds if a circuit breaker is used (unless a different time is indicated in reset procedure).
- Set the related normal cockpit control to ON, or close the related circuit breaker.
- Wait 3 seconds for the end of the reset.
