Troubleshooting
8.1.
Unsufficient pressure warning
This warning is activated when, further to an excessive consumption of air from
the utilisation, the air pressure in the built-in reservoir drops under the MINIMUM
PRESSURE set value.
To silence the alarm, press the function key
.
To exhit from the warning condition you have to allow to the pressure in the re-
servoir to increase again over the minimum value, reducing the output flow rate
of the utilization.
8.2.
Unsufficient Nitrogen pressure warning
This warning is activated when, further to an excessive consumption of Nitrogen
from the utilization, the pressure in the built-in reservoir drops under the MINI-
MUM NITROGEN PRESSURE set value.
To silence the alarm, press the function key
.
To exhit from warning condition, you have to allow to the pressure in the reser-
voir to increase again over the minimum value, reducing the output flow rate to
the utilization.
8.3.
Incorrect switch-off warning
Should the generator be switched off incorrectly without performing the depres-
surization of the sieves correctly, for instance because of a black out, the next
start-up the alarm of “Incorrect switch-off” will be activated.
The alarm is disabled if “disabled” mode is selected (editing mode parameters).
8.4.
Default data setting warning
When you supply current to the control board for the first time, when you replace
the microprocessor or when the same lose all memorized parameters data, the
warning “default data setting” appears. Acquiring it, the default value indicated
in the previous charts will be memorized.
