| Error Code | Description | Likely Causes | Immediate Actions | | :--- | :--- | :--- | :--- | | | Tamp cylinder time-out | Tamp did not extend/retract within allowed time (e.g., 0.5 sec) | Check air pressure (min 5 bar). Check pneumatic valve. Look for mechanical obstruction. | | E-L-012 | Blow-on air pressure low | Vacuum/blow pressure below threshold for label transfer | Check compressed air supply. Clean blow nozzles. Adjust regulator. | | E-L-105 | Label missing after application | Label peeled from liner but not applied to product | Static electricity issue. Product gap too large. Check blow delay timing. | | E-L-203 | Product sensor timeout (no product) | Product trigger sensor not activated within window | Adjust product sensor (photocell/ultrasonic). Check wiring. | | E-L-207 | Product speed mismatch | Encoder pulse frequency mismatch between conveyor and labeler | Check encoder wheel contact. Re-calibrate speed ratio. | Category 2.3: Sensor & I/O Errors (S-Codes) Errors from external devices, safety circuits, or internal feedback. Logopak Error Codes
Remember: Always keep a printed copy of the error code table near the machine, train operators to distinguish warnings from errors, and schedule preventive maintenance based on the most frequent codes in your history log. In the fast-paced world of packaging and labeling, mastering Logopak error codes is not just technical knowledge—it is a competitive advantage. | Error Code | Description | Likely Causes
| Error Code | Description | Likely Causes | Immediate Actions | | :--- | :--- | :--- | :--- | | | Ethernet link down | Cable unplugged, switch failure, IP conflict | Check physical connection. Ping the Logopak IP. Renew DHCP or set static IP. | | E-C-203 | Profibus DP slave timeout | Cyclic communication lost with master PLC | Check bus terminator. Verify GSD file. Monitor bus status LED. | | E-C-304 | Invalid command from host | Unexpected ASCII or binary command received | Check serial/Ethernet protocol settings. Ensure correct start/stop bits. | | W-C-401 | USB drive not formatted | USB stick inserted with wrong file system (not FAT32) | Reformat USB drive to FAT32. Use Logopak-approved USB brands. | Category 2.5: Data & Software Errors (D-Codes) Firmware, configuration, or memory issues. | | E-L-012 | Blow-on air pressure low
