Please follow all applicable safety regulations. Depicted configurations may differ from the actual scope of delivery, procedures however,
remain principally the same.
Burner Control CBR
The CBR burner control box incorporates the following
components:
•
Microprocessor controlled flame relay
•
Safety relevant temperature measurement of a NiCr-Ni
dual thermocouple for release of the appropriate operating
mode and for thermal supervision of FLOX
or safety relevant inputs for release of FLOX
mode (XOR signal processing)
•
Air / exhaust and cooling valve control
•
Manual / Automatic operation
•
Display of information, operating and fault status
messages, in a compact metal housing
The CBR controls, ignites (externally) and supervises
WS gas burners REKUMAT
operation (pre-configured self test < 24 hours).
Signal exchange with the main process control can be achieved via
Profibus DP interface or via hard wired input/output.
Depending on the power supply voltage, 4 variations, which are project customized, pre-configured and tested.
