Danfoss Electronic Oil Burner Control OBC 82 10

Description

The microprocessor based control OBC 82.10 offers stable and precise timings independent of variations in supply voltage and ambient temperature. The control is undervoltage protected in accordance with EN 298:2012. In case of undervoltage the control will prevent the burner from starting and simultaneously show a flash code. Besides this, up to five other fault types can be read out as flash codes when the control is in lockout. The design complies with the requirements of the RoHS and WEEE directive.

Function

The OBC 82.10 controls the cut-in and cut-out of the oil burner’s components and monitors that the combustion cycle is performed safely. When the boiler thermostat (TR) cuts in, heating of the oil in the oil preheater (OFV) will begin. Once the release temperature is reached and the oil preheater’s thermostat (OTR) cuts in, the burner motor will start the pre-purge and power will simultaneously be applied to the ignition (TT). Following the pre-ignition and pre-purge time, the oil will be released by valve V1 being opened and subsequently V2 will be opened. When the boiler thermostat opens after the heating period power will be cut off and all relays at the outputs will open and be ready for the next start-up cycle.
