Hint messages
provide the operator with explanatory information, for example, if an illegal key has been pressed.
Operational messages
signal the status of the system that has led to a control reaction, e.g. Emergency Stop. The message is cleared once its cause has been eliminated. In some cases, a secondary signal that has to be acknowledged is set for reasons of safety.
Acknowledgement messages
indicate a situation that must in all instances be recognized and acknowledged with the acknowledge key. They are often a consequence of a status (operational) message. An acknowledgement message stops a movement or prevents further operation.
Dialog messages
require confirmation by the operator (“Yes” or “No” softkeys). The message is cleared after
12.4 Originator
The origin of the error is indicated in this field. In the case of ArcTechDigital, the entry is TPA20.
12.5 Message text
The text of the error message is shown here.
12.6 List of error messages
To make it easier to find error messages in the following list, the message number is shown first, unlike on the display. By referring to this message number, it is possible to obtain further information on an error and the appropriate remedial action. This information is subdivided into:
Message text
is the actual text of the error message as displayed.
Cause
gives a detailed description of the cause of the error.
Monitor
indicates when the conditions for generation of the message are checked.
Effect
describes how the controller reacts to the error.
Remedy
describes what action the user can take to eliminate the error.
12 Error messages / troubleshooting (continued)
1 Message text Option bit ARC20 not set Cause -- ARC20 = FALSE Monitor -- In ARC ON command
Effect -- Endless loop always with this message
Remedy -- Set ARC20 to TRUE, stop and restart Submit interpreter, data backup 2 Message text Submit is not running
Cause -- Submit interpreter has been stopped, etc.
Monitor -- In ARC ON command
Effect -- Endless loop always with this message Remedy -- Restart Submit interpreter
3 Message text Wrong submit routine selected
Cause -- No SPS.SUB submit program running while ARC20=TRUE Monitor -- During initialization of A20_INIT commands
Effect -- Endless loop with this message, as deactivation not otherwise possible in event of interpreter stop
Remedy -- $PRO_I_O[ ] = “R1/SPS ( )”
4 Message text Weld controller not ready
Cause -- The inputs configured in the signal input group I_WELD_COND [ ] are missing when welding is activated
-- Position of the keyswitch (incorrect status for welding) Monitor -- In ARC ON command
Effect -- Endless loop with this message
Remedy -- Move the keyswitch to the correct position -- Switch on power source (I_WELD_COND [ ]) 5 Message text Ignition failure, no arc
Cause -- Configured signals not returned to input group I_START_MOVE [ ] Current flow not established
Power source sends this output too late or not at all Weld current connections broken
Monitor -- ARC_ON command
Effect -- Ignition process is cancelled and restarted, once message
6 Message text Continue without welding
Cause -- Too many ignition attempts; too many seam faults or interruption with RESTART_OPT = 0 (continue “Cold”)
Monitor -- In ARC ON command Effect -- Seam not welded
Remedy -- Clean ignition position and make new block selection to ARC_ON position
7 Message text Switch off welding
Cause -- Power source does not switch welding off or does so too late -- Incorrect configuration
-- Incorrect burnback parameters Monitor -- In ARC OFF command
Effect -- Single message for user
Remedy -- Optimization of the burnback parameters 8 Message text Weld controller fault
Cause -- Periphery error: robot waiting for the inputs expected in
I_WELD_FLT [ ]. Normally configured as current flow “Gas present”, coolant monitoring
-- Configuration error (OK state configured)
Monitor -- Continuous between ignition process and ARC_OFF command if welding
Effect -- Welding is switched off; weld process is restarted, once message acknowledged, depending on RESTART_OPTION
Remedy -- Complete the configuration
Reconnect gas, water, etc. or check respective sensor 9 Message text Welding in operation mode T1 impossible!
Cause -- T1 mode and PROC_IN_T1 = FALSE
Monitor -- In advance run section of ARC ON command
Effect -- Program remains in this loop after message acknowledged Remedy -- Set the above variable to TRUE ($config.dat)
