4.4 SYSTEM COMPONENTS
The system comprises four circuit boards: one power board and three interface boards. The hob
controls are divided among the three general interface boards:
- General interface and timer board.
- RH interface board, connected directly to the general interface board.
- LH interface board, identical to the RH board but connected directly to the power board.
The gas is controlled by a main safety solenoid valve and by four powered modulation valves (one
for each burner).
The presence of a flame is detected by four thermocouples (one for each burner).
4.4.1 POWER BOARD
The power board is customized by a software that defines all the system's control and safety
parameters. This software is entered on completion of the production of the hob.
The main functions of the power board are as follows:
- Control for spark generator for
lighting the burners.
- Flame presence detection by
thermocouples
- Control of the main safety valve.
- Control of the modulation valve for
each burner.
- Regulation, control and diagnostics
for each burner.
