PRESSURE SWITCHES
g
as control pressure swItches
The gas pressure switches can be used in three different configura-
tions:
•
Maximum pressure switch: it is activated if pressure exceeds the
value set during maximum power regulation by 20%.
•
Minimum pressure switch: it is activated if the pressure is lower
than the value set during maximum power adjustment.
•
Valve tightness check pressure switch: it checks the tightness of
the valve body in the train prior to burner start-up.
The triggering (opening of the circuit) of any of the pressure switches
when the burner is running (flame on) locks out the burner immediately.

Ir pressure swItch
The air pressure switch stops the equipment operation if air pressure is
not at the expected value.
If the air pressure switch does not detect a pressure greater than that
calibrated, the equipment runs through its cycle but does not switch on
the ignition transformer and does not open the gas valves and so the
burner "locks-out".
