    Safety Safety Classification of the Safety Instructions and Warnings The following symbols are used in this document to draw the user's attention to important safe- ty information. They are located at points where the information is required. It is essential that the safety information is observed and followed, and that applies particularly to the warnings.

  • Page 14: Target Group

    • An electrical signal low or 0 V always corresponds to a logical 0 in the CMS and is evalu- ated as inactive/safe state. If corresponding signals are connected to the CMS in a sys- tem, it must be ensured that 0 is always the safe state.
  • Page 15 OFF switch, hard-wired to the combustion air fan control circuit should be considered as the case may be. • Access to the CMS and the network in which it is located may only be granted to author- ised personnel.

Inputs/outputs The CMS is equipped with both digital and analogue inputs and outputs, see chapter 3.2 Dig- ital Input/Output Functions. and chapter 3.3 Analogue Inputs/Outputs. Integrated burner control unit A burner control unit with a sequential program is integrated into the CMS.

    In addition, the state of the existing inputs and outputs is shown as a time sequence. A detailed descrip- tion of the CMS remote software is provided in the chapter 7.3 Operation, Controls and Dis- play with CMS Remote Software Interfaces The CMS is equipped with an Ethernet interface for PC communication.
  • Page 26 In the case of a remote reset, the guidelines specified in EN 1361 must be respected. Pre-purge suppression If the signal is present during ’burner on’, CMS starts without pre-purge. Recirculation ON If this signal is absent, the recirculation channel remains at the lower range limit in burner operation.

  • Page 27: Digital Outputs

    Assignment of Input/Output Functions (logic signals to the input/output terminals) The input and output functions (logic signals) of the physical terminals in the CMS are as- signed using the I/O matrix in the CMS remote software. Among these, there are signals whose use is mandatory and those whose use is optional.

  • Page 28: Chain Functions

    16 links. These links must be assigned to a physical input via the I/O matrix in the CMS remote software package. Input functions/logic signals already assigned (e.g. main flame 1 and main flame 2) can also be assigned to a signal chain.

Particularly when setting while the burner is in operation, the actuator positions for pre-venti- lation and OFF (CLOSE) must be defined and accessible, see chapter 8.9 Settings .

    CO concentration rises noticeably. For this reason, CO control is not pos- sible with oil burners with a yellow flame. In the case of LAMTEC CO/O control, you can regulate on the basis of either CO or O , al- ternatively.

To do this, the fuel-air mixture is dynamically modified without influencing the power control unit in the direction of a lower lambda value (less air, more fuel).
