Brahma 37030018 FM31 control box

Brahma FM31 37030018 gas controllers are designed specifically for atmospheric burners of intermittent cycle and can be used both with and without a fan. These Brahma FM31 37030018 automatic gas firing devices are ideal for a variety of applications such as:

– Combined boilers;

– Heating systems;

– Air heaters;

– IR heaters;

– Water heaters.

Flame control in these Brahma FM31 37030018 controllers is based on the ionization effect, where the control electrode is exposed to high voltage, making it inaccessible to safe touch.

Construction:

– Protection from external influences:

– The plastic housing effectively protects the control unit from mechanical damage and exposure to dust and dirt.

– Protection against voltage surges:

  – The varistor ensures stable operation in conditions of voltage fluctuations in the network.

– Optimized dimensions:

  – Special manufacturing technology ensures minimal dimensions for easy installation.

Operation of the Controller:

– Self-checking of components:

– At each start, the furnace machine checks the flame signal amplifier and, if there is a fan, the air pressure switch.

– Sequential start-up:

  – After a successful self-test, a sequential start begins, including purging, activation of the gas valve, ignition, safety countdown and flame detection check.

– Activation of devices when a flame is detected:

– When a flame is detected, all necessary devices are activated, ensuring stable operation of the system.

– Manual locking in the absence of a flame:

– If no flame is detected after the safety time, the controller switches to manual locking mode.

– Detailed cyclograms:

  – Cyclograms provide additional information about the functionality of the controller, providing a more detailed understanding of its operation.

Reset the lock:

– When switching to the lock mode, the lock must be reset no earlier than 10 seconds in order to restart the controller correctly.
