3.6.1 In case of a fault
If you think that the LSIG-MM is faulty, is malfunctioning or has generated an unwanted trip, follow the recommendations below
very carefully from the Measurements menu Historicals Trip:
1. Make a note of the type of protection that has tripped by accessing the LAST TRIP page if there is an external power supply (Vaux or battery)
or by pressing “i Test” if in self-powering mode.
2. Note down type of circuit-breaker, number of poles, any accessories connected, In, Serial Number (see par. 3.3) and SW version.
3. Prepare a brief description of opening (when did it take place?, how many times?, was it always under the same conditions? what type of load?
what voltage?, what current? is the event reproducible?)
4. Send/communicate all information collected, together with CB circuit diagram, to your nearest AB Customer Assistance service.
Delivering comprehensive, accurate information to AB Assistance service will facilitate technical analysis of the problem encountered, and allow
us to promptly carry out all actions useful for the user.
