Error Description - Cebora PLASMA SOUND PC 70/T Betriebsanleitung

6 HELPFUL HINTS
- Should the equipment air contain plenty of moisture
and oil the use of a filter dryer is recommended. This will
prevent excessive oxidation and wearing of consuma-
bles, welding torch damage and reduction in cutting ra-
pidity and quality.
- Air impurities cause oxidation of the electrode and noz-
zle and may make pilot arc start-up more difficult. If this
condition is present, clean the electrode terminal end
and the nozzle interior with thin abrasive paper.
- Make sure that the new electrode and nozzle that are
going to be assembled are perfectly clean and oil-free.
- To avoid welding torch damage always use Cebora
original parts.

7 DESCRIPTION OF PROTECTIVE DEVICES
The equipment comes with different protective devices
highlighted by "Err" on the displays N (see table below
ERROR CODES).
To assure efficiency of these protective devices:
• Do not remove nor by-pass the protective devices.
• Replace them with original Cebora spare parts.
• Always replace any damaged parts of the machine
or the welding torch with original parts.
• Use torches CEBORA Type CP 162C and CP 70C
only.
DISPLAY POSSIBLE SOLUTION
Err 40 Contact the CEBORA Service Department
Err 50 Fit the guard
Err 51 Contact the CEBORA Service Department
Err 88 Contact the CEBORA Service Department
Err 53 Switch off the power source, remove the start com-
(TRG) mand and restart the power source
Err 55 Replace electrode and nozzle
Err 67 Check the supply voltage value
Do not turn off the power source, so as to maintain
the fan in operation and therefore obtain effective
cooling.
Err 73
Resetting of normal operation occurs automatically
(TH0)
once the temperature returns within the permitted
limits.
If the problem persists, contact the CEBORA Servi-
ce Department.
Do not turn off the power source, so as to maintain
the fan in operation and therefore obtain effective
cooling.
Err 74 Resetting of normal operation occurs automatically
(TH1) once the temperature returns within the permitted
limits.
If the problem persists, contact the CEBORA Servi-
ce Department.
Err 78
Increase the gas supply pressure.
(GAS LO)
Err 79
Decrease the gas supply pressure.
(GAS HI)
Err 80 Check that the nozzle holder is correctly screwed
(OPN) into place
Err 90 Turn on the CNC, exit emergency status,
(rob) check the power source-CNC connection.
