Error Messages
Following is a list of the error messages which can occur.
1
CBOX
PSOURCE
WFEED
Error in check sum EPROM
Program memory error -- The test is only carried out upon initiation after
power is turned on. No functions are blocked due to this error.
2
CBOX
PSOURCE
WFEED
Error in RAM. the microprocessor
Error in the processor’s internal RAM -- The test is only carried out upon
initiation after power is turned on. No functions are blocked due to this er-
ror.
3
CBOX
Error in external RAM
The test is only carried out upon initiation after power is turned on. No
functions are blocked due to this error.

CBOX
PSOURCE
WFEED
Voltage case in 5V supply voltage
The computer’s supply voltage has failed for some reason. This can occur
when turning off the machine. but can also be due to an error in the card’s
supply voltage.
5
PSOURCE
DC Voltage outside limit values
The voltage after the network rectifier is either too low or too high. which
can be caused by powerful transients on the network. or a weak network.
The inverter unit turns off automatically and remains blocked until the vol-
tage has decreased to under the limit value.
6
PSOURCE
High temperature
Too high temperature in the weld current source which can be caused by
overloading. defective cooling fan or other component error.
7
PSOURCE
High primary current
The inverter unit draws too much current from the DC Voltage by which it
is fed. The inverter unit turns off automatically and remains blocked until
the error has been rectified.
8
CBOX
PSOURCE
WFEED
DC Voltage 1 outside the safety limits
CBOX: Battery voltage too low
PSOURCE: The internal supply v15VC is either too high or too
low.WFEED: The internal supply voltage 15V is either too high or too low.
9
PSOURCE
WFEED
DC Voltage 2 outside the safety limits
PSOURCE: The internal supply voltage --15V is either too high or too low.
WFEED: The internal supply voltage 20V is either too high or too low.
10
PSOURCE
DC Voltage 3 outside the safety limits
The internal supply v15VB is either too high or too low.
11
PSOURCE
WFEED
Servo--error
PSOURCE: The current servo cannot handle holding the current ordered
by the computer. There is a permanent difference between shunt response
and current value.
WFEDD: The wire feed speed servo cannot handle holding the current
ordered by the computer.

WFEED
Warning status in the bus communication
The bus circuit’s error counter has such a high value that it imposes war-
ning. If the error counter continues to increase. the bus circuit is set to
”bus--off” position and the contact with the weld data unit (the controller) is
broken.
14
CBOX
Communication on the bus turned off
The bus circuit’s error counter has such a high value that it goes in ”bus--
off” position. Power--off is required for resetting.
15
CBOX
PSOURCE
WFEED
Loss of message during bus communication
The bus circuit indicates that a message has been lost due to a message
being written over by one that came in later. No functions are blocked by
this error.
17
CBOX
Lost contact with the supply voltage
An identification message is used to continuously check that a certain unit
remains on the network. ”Time out” in the response causes this message.
The stop command is immediately sent to the current source.
