LIQUID FUEL PRESSURE SWITCH SAUTER
The pressure switch is integrated in the electric safety equipment; if the
return pressure exceeds such threshold, the pressure switch switches
both burner and pump off.
If the pressure on the return circuit increases up to the calibration va -
lue, the burner stops.
The burner restarts automatically when pressure calibration values are
restored.
The burner is equipped with a safety pressure switch on the diesel
return circuit. It is installed in series to the air pressure switch and is
enabled only during diesel operation. It intervenes if it detects an incre -
asing diesel pressure equal to the preset value (5 bar).
Every time it occurs, the pressure switch opens its contact simulating
an overpressure of the liquid fuel, determining the lock-out of the flame
control equipment and therefore of the burner.
CAUTION / WARNINGS
In case of lock-out due to the tripping of liquid fuel pressure
switch, the cause of such tripping must always be checked.
CAUTION / WARNINGS
Baltur declines any responsibility for changes and/or tampering
of the safety pressure switches.
