Description
The function
of
the gauge board
is
to control the burner and to give alarm and shut
down for low and high steam pressure.
• A pressure gauge is fitted for analogous reading
of
the actual steam pressure in the
boiler.
• A pressure switch "high steam pressure" gives shut down and burner cut-offwhen
the steam pressure rises above the pre-adjusted set point. The pressure switch locks
the burner in stop mode. Operation
of
the burner is only possible when the steam
pressure falls below the differential set point
of
the pressure switch and the shut
down function is reset.
• A pressure transmitter connected directly on the boiler convet1s the actual steam
pressure
of
the boiler into corresponding electric signals. The signals are used to
give alarms for lowlhigh steam pressure and shut down/burner cut-off for high
steam pressure. The signals also control start/stop and modulation set point
of
the
burner. Furthermore, the pressure transmitter can be used for remote steam pres-
sure indication.
