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 Recalling the manufacturer defaults
From the main screen press ENTER until the password screen is shown:

Confi rm by pressing ENTER or exit by pressing ESC
If no button is pressed for 30 seconds, the display returns to the main
screen.
6.7 Display software release
1) when switching on the unit to display "rel. x.y "(example rel. 1.2)
2) during operation
