Construction

The components of the Brahma VE3.2 18006015 control unit are mounted on a pressed frame made of heat-resistant material with high dielectric resistance. The plastic case protects the device from possible damage as a result of accidents, careless opening, dust ingress and contact with the external environment.

Flexible unipolar conductors of different sizes connect the components of the control system, with the exception of the flame detection and pre-purge circuit, which is mounted on a printed circuit board.

Flame control

A transformer having one primary and two secondary windings feeds an electronic flame detection circuit with a low voltage, and a detection sensor with a voltage of about 300 V. 

The great advantage of this power supply system is the presence of constant ionization values, even if the network is operating in real time.

To check the effectiveness of the flame detection circuit, you need to do the following: connect an ammeter with low resistance;

Series-connected resistors must provide a total resistance value of 200 mOhm (for example, 20 resistors of 10 mOhm 1/4 W 5%).

If the Brahma VE3.2 18006015 control unit is powered by 220 V mains, the measured current value is about 0.5+0.6 µA DC, which leads to the ignition relay being switched on. Lower current values indicate that the circuit is damaged or only partially working.
