Immediate attention from a qualified operator or maintenance technician is required to prevent secondary damage to the equipment or spoiled parts during the manufacturing cycle. Always ensure standard safety and LOTO procedures are followed before accessing electrical cabinets.
Official Troubleshooting Steps
Cause: No $ERROR_PROG has been defined for this JOB. This fault will only appear if the Karel variable [SLERROR]POST_NO_ERRP is set to TRUE (default = FALSE). Remedy: Use the TPE ERROR_PROG command, under Program Control, to set up an Error Program for this JOB. This will allow the robot to move out of the work area when an error occurs.
