A part of a control system I do not understand
A part of a control system I do not understand
(OP)
This is a part of a control system I do not understand how it works. But to explain a little how it should work and see attached drawing. It is the clowded part I like to understand.
The power supply is indicated as N L1 L2 L3 and PE.
Q0 is the main breaker that needs to open when we have either fire detection of toxic gas detection, both indicated with F.D or toxic gas.
QMX is a main cuircuit breaker trigger.
How is this system intendet to work?

You pretty much explained how it works. As long as QMX is shut, when either a fire or toxic gas is detected, the associated switch closes, providing a complete circuit to energize trip coil Q0 (with pins A1 and A2) with the 230 V potential difference between L1 and N which trips Q0 breaker.

Without knowing exactly what the purpose of this equipment is, it is difficult to have a well-grounded opinion. But this is my best guess.
