Code 702134: Error air sensoring 2 (part not clamped correctly)
Issue Description & Safety Warning
The Chiron Siemens-Control CNC has triggered a critical Error air sensoring 2 (part not clamped correctly) alarm. 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
If the clamping device is clamped and the clamping sequence is completed, it is checked once again whether the PLC input signals "Insertion check table side 2“ or "Insertion check nest 2“ are still present. If they are not present, an error message appears. The clamping device is automatically opened again. 1. Check whether the workpiece was inserted correctly. 2. Check the setting of the airsensoring unit. 3. Check the PLC input signals "Insertion check table side 2“ or "Insertion check nest 2“. 4. If the PLC input signals for airsensoring signal the signal state (1), the clamping device can be clamped again and the message will be cleared automatically.
