Brahma 37511002 DE11 control box

Brahma DE11 37511002 gas control units provide a reliable and efficient solution for controlling atmospheric gas and liquid fuel burners in systems with intermittent operating cycles. This Brahma DE11 37511002 automatic ignition system provides the user with two versions of fault reset – manual and electric. In the case of a manual reset, the operator can easily restart the burner by pressing the appropriate reset button, while in the case of an electrical reset, the main power must be disconnected and reconnected to successfully restart the burner.

These Brahma DE11 37511002 controllers are designed for use in a variety of installations including combi boilers, heating systems, steam boilers, air heaters, infrared heaters, convectors, water heaters, furnaces and block burners. Thanks to their reliability, flexibility and ease of operation, Brahma DE11 37511002 combustion managers provide an effective solution to ensure stable and safe burner operation in a variety of applications.

Design

The plastic case provides reliable protection of the controller from mechanical damage, dust and dirt under operating conditions. The technology used for the production and surface installation of electronic components allows us to maintain the minimum dimensions of the controller, making it compact and convenient for installation. Additional protection is provided by a varistor, which protects the controller from voltage surges in the power supply network.

Electrical connections

• The installation must comply with national requirements and European standards (eg EN 60335-1/EN 50165) for electrical safety;

• Phase and neutral must be connected correctly, an error may lead to dangerous situations. If phase-neutral is not observed, the controller will operate in manual reset mode after the start-up safety time has expired;

• Before starting the system, check the cable connections carefully. Incorrect connection may damage the controller and compromise safety;

• Check the grounding of the controller, the metal body of the burner and the grounding of the main power supply;

• Ensure the distance between the ionization cable and the power/ignition cables;

• Use the shortest and straightest possible ignition cable (max length 25kV).
