3.5 Main Screen of the Burner Controller
The Burner Controller is used for the controlled ignition of an oven and its monitoring after ignition.
First both MFCs and both solenoid valves are closed. The actual values of both MFCs are dis-
played in the bottom left corner of the screen.
In the case of the Burner Controller a series connection of four zero potential contacts is moni-
tored, consisting of two pressure monitors arranged upstream of the MFCs, one emergency off
switch and a fourth contact supplied by a monitoring camera which detects a flame in the oven.
Please keep in mind that the series connection will only signal a „good state“ when all the contacts
are closed. Opening a single contact is sufficient to set the „bad state“.
We will assume that both pressures are okay and that the emergency off switch has not been
pressed. Then the good/bad state will only be set by the contact of the camera.
