3 false alarms without cause

Post by jjaimevera »

Last night I had three false alarms. In my town has been raining two weeks daily and 2 modules CT1 damaged me, the first short circuit and the second just stopped answering the serial number, it does not exist in the mapping. I replaced the first and reprogram it, the second I removed from the database, leaving only a bridge circuit.

At midnight had 3 false alarms without cause, in three different independent zones each other. Do not understand what could be the cause. I do not want to happen in days with full plant.

hi,
did you check the SIGA CT1 you changed?
as my experiences there are some damaged CT1 gives you alarm and noway to reset it also,I installed a CT1 with 47k on the input(waiting for LHC installation)but it gives me alarm like this.
courage sometimes alarms are misterious.
regards,
