Cause : Telegram failure at paralleling interface (active when U800 = 1 or 2 from the first receipt of a valid protocol in all operating states)
After the receipt of the first valid protocol, no further telegrams have been received within the time period set in parameter U807.
Possible fault causes
♦ Interruption in connecting cable
♦ EMC interference on connecting cable
♦ U807 is set too low
