Humidifying / Heating Up The steam humidifier produces steam if a
demand from the hygrostat or controller is present (safety interlock
must be closed).
After a humidifier cold start-up, or after a full blow-down, Heating up
displays for a short time. The display reads Humidifying only after the
first refill.
Stand-By
The safety interlock is open. The unit is producing no steam.
No Demand
The demand value from the controller is less than the activation point
of the steam humidifier. The unit produces no steam.
Filling
The control activates the inlet solenoid valve. The cylinder is supplied
with water.
Stand-by Blow-Down
If the controller or hygrostat demands no humidity from the humidifier
for a long period of time, a full-blown is automatically performed after a
specified period. This prevents standing water in the cylinder. The dis-
play shows Blow-Down. Set the time period using Parameter Stand-By
Draining (A4).
Partial Blow-Down
In order to dilute the concentration of the cylinder water, the con-
trol regularly performs a partial blow-down.
Full Blow-Down
Depending on water quality, a complete blow-down is done every 3-8
days.
Blow-Down overcurrent
At cold start-up, the nominal current increases to a maximum of 128%
in order to achieve a rapid start-up. When this current value is reached,
a
power surge blow-down is triggered and performs partial drainage
of the cylinder.
Dilution
The Dilution message is displayed if an additional partial blow-down is
required. This occurs for example at high conductivity levels, with a
significantly fluctuating control signal, or when drainage is blocked.
Sicherheitsstop
Safety stop With this parameter you determine if and when the steam
generator should stop operation after the safety interlock has been
closed. If the steam generator stops the message „Safety stop” is dis-
played. By opening and closing the safety interlock the steam genera-
tor restarts operation for the programmed hours.
With parameter D5 you determine if and when the steam generator
should stop operation after the safety interlock has been closed. If the
steam generator stops the message „Safety stop” is displayed. By
opening and closing the safety interlock the steam generator restarts
operation for the programmed hours.
