Related fault records
Nittan Evolution • Battery high impedance faultBattery internal resistance too highThe panel has measured the battery internal resistance and determined it is too high. The batteries will need to be replaced.Nittan Evolution • Battery RemovedStandby batteries missing or disconnectedCheck the battery fuse, check that battery connections are secure, check battery voltage (should be around 26-27V for well-charged batteries), check that the two batteries are connected in series, and check the charger fuse.Nittan Evolution • Break in -ve wire (ISOLATOR FAULT)Nittan evolution 1: Break in -ve wire (ISOLATOR FAULT)Reported as an ISOLATOR FAULT with a description. The manual says to use the same method to locate the break (re-run the loop search and check the detailed loop report). In its example, the break is between address 150, seen from side A only, and address 152, seen from side B only; this applies if the loop is addressed sequentially.Nittan Evolution • Break in +ve wire (ISOLATOR FAULT)Nittan evolution 1: Break in +ve wire (ISOLATOR FAULT)The manual says the panel's loop isolator monitors the addressable loop for open and short circuit faults, reported as ISOLATOR FAULTS with a description. For a break in the positive wire, it says to locate the cable break by re-running the loop search and checking the detailed loop report after the search is complete.Nittan Evolution • Cable break (loop contents different from expected)Nittan evolution 1: Cable break (loop contents different from expected)If the loop contents differ from what was expected, the manual lists a cable break as a probable cause. If a system is only wired as a loop, any breaks will be reported and can be located as in section 12.1. If a system uses spurs, a cable break in a spur will not be seen: look for missing device addresses in the loop report.Nittan Evolution • Charger FaultPower supply is not charging the batteriesThe panel has determined that the power supply is not charging the batteries. This is likely to be a problem with the Charger PCB — contact the supplier to arrange a replacement.
