5. COMPACTSTEAM OPERATION
5.1 Displaying information
The information shown on the display during the normal operation of
compactSteam is the instant current in amperes running between the
electrodes. To display other information, press and hold the “reset/sel”
button until the display shows the required information. When holding
the button, every 2 seconds the display will scroll between the current,
the percentage (%) of steam production, the hour counter and then the
current again (Fig. 5.a).
Fig. 5.a
1. Instant current: this is the current that fl ows through the water to make
it boil (default display).
2. percentage (%) of steam production: this is the steam production
(proportional to the current), expressed as a percentage of rated
production.
3. hour counter: counts the operating hours, proportional to the % of
cylinder production (this must be reset whenever the cylinder is
replaced). For example, if the cylinder has worked for 100 hours at
50% production, the number of proportional operating hours is 50.
The value is expressed in tens of hours, so for example when the
display shows 13, the real number of operating hours is between 130
and 139 hours. Once 1990 hours have elapsed (199 on the display),
the hours are displayed in hundreds. Example: 21 = 2100 hours.
Selecting the type of signal
Note: select the correct control signal type on the keypad before
connecting the control wiring.
To select the type of control signal proceed as follows:
1. Turn compactSteam off .
2. Turn compactSteam on again, while holding the two buttons, “reset/sel”
and “drain”, until the display shows“00” and the wrench symbol
fl ashes; then release the two buttons.
3. Then hold the “reset/sel” button to scroll the numeric parameters on the
display. Hold “reset/sel” for a few seconds until the display shows
“02”.
WARNING: If the display shows a value higher than “02” do not
confi rm, but rather press “reset/sel” until the display returns to
normal operating mode and start again from point 1.
4. Press the “drain” button for at least 1 second to confi rm the value: the
display will show “P1” for 1 second and then the value of parameter
P1 currently set will be displayed alongside.
5. Pressing “reset/sel” switches the value of P1 between “0” and “1”:
0 = humidistat;
1 = external 0 to 10 V modulating signal
6. Press the “drain” button for at least 1 second to confi rm the new value of
parameter P1 and return to normal operating mode.
7. Turn compactSteam off : now the control wiring can be connected.
Note: If no selection is made within 3 s, the software automatically
returns to normal operating mode.
5.2 Setting the maximum steam production
To adapt the compactSteam to the specifi cations characteristics of the
environment, the maximum steam production can be set between 20%
and 100% of rated production, in steps of 5%. To set the maximum steam
production:
1. Turn compactSteam off .
2. Turn compactSteam on again, while holding the two buttons, “reset/sel”
and “drain”, until the display shows“00” and the wrench symbol
fl ashes; then release the two buttons.
3. Then hold the “reset/sel” button to scroll the numeric parameters on the
display. Hold “reset/sel” for a few seconds until the display shows “01”.
WARNING: If the display shows a value higher than “01” do not
confi rm, but rather press “reset/sel” until the display returns to normal
operating mode and start again from point 1
4. Press “drain” for at least 1 second to confi rm the value: the display shows
“P0” for 1 second and then the value of parameter P0 currently set will
be displayed alongside.
5. Pressing “reset/sel” scrolls the value of P0 from 20% to 100% in steps of 5%
6. Press the “drain” button for at least 1 second to confi rm the new value of
parameter P0 and return to normal operating mode.
Note: If no selection is confi rmed within 3 s, the software
automatically returns to normal operating mode.
5.3 Manual drain cycle
Holding the “drain” button on the front of the unit activates the manual
cylinder drain cycle. Hold the button until the cylinder is empty..
5.4 Resetting the hour counter
The hour counter must be set to zero whenever the cylinder is replaced,
so as to cancel and restart the maintenance timer:
1. Turn compactSteam off .
2. Turn compactSteam on again, while holding the two buttons, “reset/sel”
and “drain”, until the display shows“00” and the wrench symbol
fl ashes; then release the two buttons.
3. Then hold the “reset/sel” button to scroll the numeric parameters on the
display. Hold “reset/sel” for a few seconds until the display shows “03”.
WARNING: If the display shows a value higher than “03” do not
confi rm, but rather press “reset/sel” until the display returns to normal
operating mode and start again from point 1
4. Press “drain” for at least 1 second to confi rm the value: the hour counter
is immediately reset and compactSteam returns to normal operating
mode.
Note: If no selection is confi rmed within 3 s, the software
automatically returns to normal operating mode.
