8 UP/DOWN ARROWS Use the arrow keys to scroll the menu, to program changing parameters and
to put in the password. Three passwords are programmed: 1) to start the
isolator – 2) to enter the operator menu – 3) to enter the main menu to
change the data input (allowed only to authorized technical staff – service –
because unsuitable interventions can cause troubles and incorrect operation
of the isolator).
9 ESC ESC key deletes the operation of data input and goes back to the starting
condition.
10 SET SET key lets you enter the different functions or confirm the data input going
back to the upper level.
11 STATUS If pressed in sequence, the following data will appear on the display:
External Temperature: Shows the temperature outside of the isolator; the
LCD will display (for example) "EXT. TEMPERATURE=27°C" This value is
taken by an electron probe installed outside the isolator.
Internal Temperature: Shows the internal temperature of the isolator work
area; the LCD will display (for example) "INT. TEMPERATURE =30°C”. This
value is taken by an electron probe located inside the isolator.
U.V. Lamp Residual Lifetime: Shows the operating time of the U.V. lamp
pre-set by the user with the appropriate keys. The LCD will display (for
example) "U.V. TIME=XXXX h”. When such time is over, the message "U.V.
LIFETIME OVER" will appear on the line below.
F1, F2, F3 and F4 Residual lifetimes of filters: it is the operation time of the
filters installed in the isolator that can be programmed by the user.
The LCD will display (for example)” RES. TIME FILTER 1=XXXX:YY h:min”.
When such time is over, the message “CHECK FILTER (es.) 1”. Will appear
on the line below.
The filters installed in the isolator follow the numbering listed below
TYPE of FILTERS NUMBER
LAF HEPA 1

proportion by a bar.
The display shows the notice: "MOT.LAF = XX % " (max.100%).
EXH Power: it is shown indirectly by the power supply voltage of the suction
motor, expressed as percentage of max. load voltage displayed also in
proportion by a bar.
The display shows the notice: "MOT.EXH = XX % " (max.100%).
