Code 510116: RSF60 filter dirty
Issue Description & Safety Warning
The Chiron Siemens-Control CNC has triggered a critical RSF60 filter dirty 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
The float switch "Coolant level super-clean water minimum" registers minimum for about five minutes. If the super-clean water tank is not filled within this period, an alarm will be output. Feed Stop after end of program (Program end with M02, M30 or change work area / table side) Activation of the 2nd coolant pump (M6.1) is switched off (motor + valves). 1. Check the reverse flow filter (contamination). 2. Check float switch "Coolant level super-clean water MIN" and the PLC input signal. 3. Check the filling of the super-clean water tank. 4. Once the float switch signals OK again (signal state = 1), press one of the following keys: [CYCLE START] [DELETE ERROR] Message is acknowledged and the machining program can be continued. 5. Switch to manual mode. 6. Press [RESET] key. Message is cleared and the coolant pump (high pressure) starts up again to fill the super-clean water tank. Changeover to operating mode "JOG" and actuating the [RESET] key deletes the error and the coolant pump (high pressure) is reactivated to fill the super-clean water tank. The super-clean water tank is filled up over a bypass pipe in the second coolant pump (M6. 1 ). Error messages Cooling lubrication RSF60 filter dirty
