6. ERROR CODES OF PANELS
By Promig 501 and 511 units check by each start, if there are error states in the equipment;
in case error states are observed, the error state in question is shown by means of Err textes
appearing on (wire feed) display of panels (see enclosed figure).
Error codes are among others the following:
Err 1: PROMIG has gone over to MMA welding, though you have already selected MMA
welding on power source panel.
Err 2: You are pressing on start switch of gun, when data transmission between PROMIG
and PRO is broken (defect in control cable or in connector), or you are pressing on
gun switch, when MMA welding has been selected on control panel of power source.
Err 4: You are pressing on start switch of gun and selecting switch S12 for cooling mode of
gun is in liquid position and you have forgotten to switch-on the PROCOOL cooling
unit or you have forgotten to connect it to equipment.
Err 5: PROCOOL cooling unit has stopped welding. Reason can be break of supply voltage
from PROCOOL, pressure of liquid circulation doesn´t arise or temperature of cooling
liquid has arisen too high.
Err 6: Wire feed unit has stopped welding in liquid position of selecting switch S12 of
air/liquid-cooled gun for PROMIG, because data communication to cooling unit is
broken (defect in intermediate cable or in connection).
Err 7: Selecting switch S12 of air/liquid-cooled gun for PROMIG is in air position,
PROCOOL is switched-on and start switch is pressed down. Purpose of operation is
to prevent the liquid-cooled gun from being destroyed, if the selecting switch S12 for
air/liquid-cooling is in wrong position.
Err 8: Liquid-cooled PMT or WS gun is overheated.
Err 9: Overload of wire feed motor, which can be caused e.g. by blocked wire guide of gun
or by gun cable, which is too much curved.
Err 10: Operation of thermal release of PRO power source has stopped welding.
Err 11: You try to use the PMT or WS gun, when their use is prevented with the 5. jumper
operation.
Err 12: Welding has been stopped, because so colled door switch or gas guard has operated
(operations need extra mountings to standard unit).
Eliminate the error codes as follows:
Error code Err 1 is eliminated when PROMIG wire feed system is set into MIG state.
Blinking of error codes Err 2-4 ends automatically within 5 s, if the trigger is not pressed
down.
Eliminate the reason of error before next start.
Blinking of error codes Err 5-12 ends by next start, if the reason of error code has been elimina-
ted.
