KKoether61 Posts: 3 Rating: (0)	Today we came up with a 230042 Alarm on an 840D SL control. The complete message is: DP003.Slave003: ALM_3.3:2 (2) Power Unit: Fan operating time reached or exceeded. 0. I get that we have a fan that is in need of replacing. My question is which fan? This machine has numerous power modules and drives or does this message indicate all the fans need replaced? Thanks!
