from the main screen: pressed for 5 seconds disables/
enables the humidi er
UP from the main screen: display the humidi 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 humidi cation values
(current, conductivity,....)

from the list of parameters: select and con rm (like the
“Enter” key on a computer keyboard)
6.5 Main display
The display on the humidi 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 (S/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 con 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 humidi er can be disabled in 3 di 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--•
Before starting the humidi er, check:
water connections: chap. 2. In the event of water leaks do not start the □
humidi er before having resolved the problem;
steam distribution: chap. 3 and electrical connections chap. 4 . □
