The FlexES Control local essernet receive buffer has reached 100 percent because one or more network participants have not acknowledged telegrams despite retries. FAQ 1001 treats codes 98 and 99 as one combined…

After the detector loop is switched on, Störungscode 24 means that an automatic detector cannot correctly control its base board. A base relay PCB may not be reliably controlled, so required event control can fail.…

An IQ8Wireless participant has a radio communication fault. FAQ 1010 directs the engineer to inspect preceding Batt < 30 and Batt < 7 indications as evidence of depleted batteries; those indications are references only…
