Okuma OSP Alarm A 8617 - Thru-the-tool coolant filter clogged
Thru-the-tool coolant filter clogged
The clogging detection pressure switch on the thru-the-tool coolant tank filter has tripped, indicating the filter is restricted. The code shows which pump was running when the restriction was detected.
Common Causes
- Thru-the-tool coolant filter element genuinely clogged with swarf/chips
- Clogging detection pressure switch faulty or its wiring damaged
Troubleshooting Steps
- 1Read the code number shown with the alarm: code 1 = Detected while the high-pressure through-spindle coolant pump ON signal was being output; code 2 = Detected while the washing gun motor ON signal was being output
- 2Read the code: Code 1 means the alarm occurred while the high-pressure through-spindle coolant pump ON signal was being output; Code 2 means it occurred while the washing gun motor ON signal was output.
- 3Clean the filter in the thru-the-tool coolant tank; replace the element if cleaning does not restore flow.
- 4Run the pump indicated by the code and confirm the alarm clears and pressure normalizes.
- 5If the filter is clean but the alarm persists, test the clogging detection pressure switch and its wiring; replace the switch if it stays tripped with a clean filter.
