Malfunctions and warnings
In case of malfunctions of the unit caused by thermal
overcharging or overpressure, the gas production is
automatically stopped: the unit changes the set value to zero. A
signal tone indicates the malfunction. The valve at the handle
piece can be closed easily. The signal tone can be silenced by
pressing any key.
If the main transformer is overloaded, the display shows the
following malfunction:
Transf. overload!
Let cool down!
Operation can be continued only after the transformer has
cooled down. For this, change the set value back to the
required value.
If the allowed reactor temperature is exceeded, the display
shows the following malfunction:
Excess temp.!
Let cool down!
Operation can be continued after the unit has cooled down. For
this, change the set pressure value back to the required value.
In case of malfunctions due to overheating it is important not to
switch off the unit at the mains switch, as the ventilating device
stops operating, too. If you feel uncomfortable due to a too
noisy operating sound of the ventilating device, switch the unit
into stand-by operating mode by pressing the
on/off
key
.
This reduces the speed of the ventilating device. In this mode,
cooling down will take considerably longer!
If the pressure control device has broken down the unit
automatically switches off and the display shows the following
malfunction:
Faulty pressure control!
Switch off the unit at the mains switch and restart it. If the
malfunction is repeated please contact your supplier or the
manufacturer of the unit.
