  • Page 4: General Information

    • BT341 Faults NOTICE The LAMTEC burner controls use different methods to detect fault messages between main processor and watchdog processor: BT300/ETAMATIC/FMS/VMS/FA1: The bus transmission does not generally use different fault numbers to distinguish between watchdog processor and main processor faults. In order to distinguish the main processor fault messages from the watchdog processor fault messages, an offset of 10000 is added to the watchdog processor faults.

  • Page 9 List of Fault Codes P301 = 0 P301 = 2 Description Different operation modes on both controllers Main processor and watchdog processor detect the digital input signal at slightly different times. A signal change is hap- pening only for such a short time that only one of the two pro- cessors detects it.

  • Page 20 EN 14459 allows only 4 remote fault resets every 15 min. The fault reset is monitored by LSB Remote Software, UI300, LAMTEC SYSTEM BUS and field bus. Exceeding the num- ber of fault resets causes the fault shot-down 889 and further remote fault resets are ignored.
  • Page 21 List of Fault Codes P301 = 0 P301 = 2 Description Internal fault – Reset fault – If the fault still exists: Send error number and diagnostic code to the technical support. – Replace the device DFM: Fuel selection relay is defective or no/inconsistent feedback Invalid fuel selection in the DFM or inconsistent feedback from DFM.
