Before starting the humidifi er, check:
□ water connections: chap. 2. In the event of water leaks do not start the
humidifi er before having resolved the problem;
□ steam distribution: chap. 3 and electrical connections chap. 4 .

6.1 Starting

1
ON
2 if the cylinder is new, run a pre-wash cycle by pressing ENTER +
DOWN for 5 sec. (the cylinder is fi lled and emptied three times,
cleaning the inside walls from impurities).
A display shows the symbol PRE Cln

6.2 Stopping

1
empty the water in the cylinder to avoid stagnation (see paragraph 6.6
"Manually drain the water in the cylinder").
2
OFF

6.3 Display

return to the previous display
from the main screen: pressed for 5 seconds disables/
enables the humidifi er
UP from the main screen: display the humidifi cation values
(current, conductivity,....), see the following paragraph
from the list of parameters: circular navigation of the
parameters and set the values
DOWN from the main screen: display the humidifi cation values
(current, conductivity,....)
from the list of parameters: circular navigation of the
parameters and set the values
ENTER for 2 seconds: access the list of parameters
(PRG)
from the list of parameters: select and confi rm (like the
"Enter" key on a computer keyboard)

6.5 Main display

The display on the humidifi er normally shows the current steam production
(kg/h, basic display).
To display other values, press UP or DOWN and scroll the following list:
•
input signal (0-100%, or ON/OFF if A0=0)
•
access alarm log (HYS ) (**)
•
set maximum steam production (parameter P0) (*)
•
current (A)
•
conductivity (μS/cm)
•
cylinder hour counter (h)
To return to the basic display, press ESC.
Parameter C0 (see chap. 7) can be used to change the value of the basic
display (default: current steam production).
(*) To modify the maximum steam output (P0) press:
•
ENTER (display: )
•
UP or DOWN to set the value percentage of production (from 20 to
100%)
•
ENTER to confi rm the new value
Press ESC to return to the main screen
Parameter P0 can also be accessed from the list of parameters (see chap. 7).
(**) To display the alarm log (HYS ) press:
•
ENTER (the most recent alarm is shown)
•
UP or DOWN to scroll the list of alarms in chronological order
press ESC to return to the main screen
To delete the list of alarms press UP and DOWN for 5 seconds (inside the
alarm log), when the list has been reset the display will show 'res' .

6.6 Disabling

The humidifi er can be disabled in 3 diff erent ways:
•
Opening contact M2.4 and M2.5 (enable) : the display shows C--
•
From serial (see Chap. 7 Digital 2) : the display shows S--
•
From terminal (see ESC button) : the display shows t--
18
to indicate 1000 (only
).
