Laser emission despite no coolant flow
1. Open RDWorks.
2. Access the “Vendor param”(password: rd8888) and check that “Water Protect” is ticked (as shown).
If the box has been ticked, unplug the line to the WP port on the laser control terminal.(as shown)
- If the laser becomes erratic and the control panel displays "water error” or “cooler error”, then the water protection sensor is short-circuited or the water protection system has a wiring problem. Replace the faulty one with a new, identical one.
- If the laser still fires normally with the line to the WP port removed and the control panel is displaying no error code, then the mainboard is faulty. Replace with a new, identical one.
