hello
today i redid a sensor (new) maintenance
taken out of service for about 1 hour !
restarted in the middle of the afternoon (3:30 pm GMT) ==> it seemed ok
ten minutes later, again channel "A" down  :evil:
a year after commissioning the sensor already a malfunction and the warranty naturally has expired  :twisted:

Either you replaced Sensor B accidentally or you got a dud. Does happen.
