CEA MATRIX 3000 AC/DC R Operator's Manual page 39

PLEASE NOTE: If the fault persists look for the cause of the
fault and contact our technical assistance department if nec-
essary.
All of this is necessary to allow our technical assistance depart-
ment (which must be contacted each time error messages
appear on the equipment's operator interface) to resolve prob-
lems more easily, as quickly as possible and thanks to the user's
reports, also because, in the meantime the machine will not allow
the operator to do their work.
Display
PRESSURE SWITCH
This message appears when the cooling equipment
is connected to the machine and its pressure switch
E01
does not close due to a lack of pressure in the
hydraulic circuit.
Automatic reset error.
OVER VOLTAGE
This message appears when the power supply
voltage for the MATRIX 3000 AC/DC - AC/DC R
exceeds 500V.
E02
If the fault persists look for the cause of the fault
and contact our technical assistance department if
necessary.
Automatic reset error.
UNDER VOLTAGE
This message appears when the power supply
voltage for the MATRIX 3000 AC/DC - AC/DC R
drops below 280V.
E03
If the fault persists look for the cause of the fault
and contact our technical assistance department if
necessary.
Automatic reset error.
THERMAL PROTECTION
The welding stops due to an excessively high
t°C
temperature (thermostat activated).
Automatic reset error.
WARNING: The MATRIX 2200 AC/DC welding machine has a
built-in electronic protective device to deal with fluctuations
in mains voltage that switches the machine off automatical-
ly (voltage exceeding 300 V), without indicating any type of
error or warning message for the operator. Subsequently it
starts functioning again automatically when the voltage has
dropped to below the value indicated above.
