K8061 looses voltage as analog output TLV274

Hi,

I use homeseer with 3 K8061, on card #2 I have connected a 8 channel dimmer. 0-10v means 0-100%dim. It runs for 4 months now
Sinds 2-3 weeks something strange happens:

The voltage on every analog output of card #2 drops to 0V so this mean that 8 lamps are burning 100%. But I do not give any command for it.
If I look into the log of homeseer no light on command is logged. But now it comes: If I send the command to 1 of the 8 analog outputs to set the output at 10V then the other 7 go to the correct state.

So in short:
Error starts
all 8 lights are burning
send command 0V to output 1 (or any other analog output) 0v means lamp on
output 2-8 are set correctly (lights off)
output 1 0V (lamp on)
error is gone.

  • I already have replaced the TLV274
  • measured and logged the 10v at J4 & J5
  • It happens during the day and during the night
