Initial blow-
down
After switching the device on, a blow-down
sequence is run with the parameter set for partial
blow-down.
61
Partial blow-
down
A partial blow-down is run in order to achieve cylin-
der water concentration reduction. In order to dilute
the concentration of the cylinder water, the control
performs regular partial blow-downs.The blow-down
icon in the display is lit.
Blow-down cate-
gory (contd.)
62
Full blow-
down
Full blow-down is run (steam cylinder is completely
drained). The blow-down icon in the display is lit.
63 Dilution
(only for elec-
trode steam
humidifiers)
A partial blow-down is run (with the parameter set
for partial blow-down) due to a water conductivity
too high. The blow-down icon in the display is lit.
64
Overcurrent
blow-down
(only for elec-
trode steam
humidifiers)
An overcurrent blow-down is run since an electrode
current too high was detected by the device. Reduc-
ing water level also reduces electrode current.The
blow-down icon in the display is lit.
65
Max. level
(only for heater
steam humidifi-
ers)
Max. allowable water level in steam cylinder was
overrun.
66
Stand-by
blow-down
In case of a safety interlock open for a longer period
of time, a full blow-down is run automatically after a
time preset in order to avoid stagnant water in the
steam cylinder. The blow-down icon in the display is
lit.
67
Dead leg
flushing
Special blow-down mode for flushing dead leg tub-
ing. Solenoid valve and blow-down pump are acti-
vated simultanously in case of a no demand
situation for a certain period of time. The blow-down
icon in the display is lit.

Partial blow-
down waiting
Device will start partial blow-down with next filling
step.
81
Full blow-
down waiting
Device will start full blow-down with next filling step.

Cylinder full
(only for elec-
trode steam
humidifiers)
On detection of a an electrical potential at the sen-
sor electrode, cylinder full is reported. In this situa-
tion cylinder water level is so high that an electrical
bridge between one of the power electrodes and the
sensor electrode has built up. The steam icon in the
display flashes.
