AIR PRESSURE SWITCH
The air pressure switch stops the equipment operation if air pressure
is not at the expected value.
The pressure switch must therefore be adjusted so that it is triggered
to close the NO (normally open) contact when the air pressure in the
burner reaches a particular value.
To ensure correct operation of the air pressure switch you must, with
burner on and in 1st stage, increase its regulation value until the burner
triggers and then it immediately “locks-out”.
To unblock the burner, press the special pushbutton and return the
pressure switch regulator to a sufficient value in order to measure the
air pressure existing during the pre-ventilation phase.
In burners of the IB... series, the air pressure switch is located inside
the electrical junction box next to the air conveyor.
Air pressure sampling point is upstream the air dampers.
LIQUID FUEL SAFETY PRESSURE SWITCH ON RETURN CIRCU-
IT
The burner is equipped with a pressure switch that controls the liquid
fuel pressure on the return circuit.
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.
Its pressure range is 1-16 bar and is set by default to 2/3 bar.
If the pressure on the return circuit increases and reaches this value,
the burner turns off
The burner will automatically restart if the pressure drops again below
2/3 bar.
CAUTION / WARNINGS
Baltur declines any responsibility for changes and/or tampering
of the safety pressure switches.
CAUTION / WARNINGS
In case of lock-out due to the tripping of liquid fuel pressure swi -
tch, the cause of such tripping must always be checked.
Check that there is no clogging in the return line.
