Kromschroeder 88600349 BCU370WI1FEU0D3B1-3 control box activates the fan and sets the connected butterfly valve to Pre-purge and Ignition position. After pre-purge and burner start, the Enable signal is issued to an external controller, which positions the butterfly valve in accordance with the output demand. Post-purge occurs after the end of burner operation. Kromschroder 88600349 BCU370WI1FEU0D3B1-3 control unit monitors the gas and air pressure. An optionally integrated tightness control function checks the valves with an external gas pressure switch. Programmability by means of the optical interface and BCSoft PC software guarantees optimum adaptation to the relevant application. Adjustable start-up attempts and automatic restart, which can be activated, ensure the high flexibility of the burner equipment. The quick-start option allows standard-compliant startup of the forced draught burner without pre-purge after normal shutdown. This avoids unnecessary admission of air into the combustion chamber. The heat output is available as quickly as possible after a temperature demand.
