Failure display
If a failure occurs the red LED on the side of the converter flashes/shines. The number of pulses after
a longer break allows the assignation of the status according to following chart:
Status code Meaning Measure
red
permanent
on Low voltage - Increase wire cross section (extension cord)
- Check supply cable (cable interrupted)
- Use a generator with more power
red 1x pulse Over temperature
motor - Increase water flow (cooling of motor or converter is
too low; water temperature is too high)
- Check hose connection
Never use waste water for cooling!
red 2x pulse Over temperature
frequency converter
red 4x pulse Overcurrent - motor stops, motor has been used in the overload
range
- Check motor cable and plug connection for damages
(short circuit)
red 5x pulse Overload - Reduce machine load, motor is operated in the
overload range
red 6x pulse Encoding error - Check plug contacts of machine and frequency
converter for dirt and damages
- Update frequency converter (encoding unknown)
red 7x pulse Over current power
modul - Check motor cable and connectors for damages
(short circuit)
Status display changes its status automatically. Fault signals will be deleted when the machine is
restarted (if the cause of defect has been removed).

6.1 Diamond core bits
The tool fixture is prepared for standard drill bits with G ½" (HD16), 1 1/4" UNC (HD1603) or the new
M33/3 thread (special model HD1608).
Only use appropriate diamond tools of high quality.
Especially when drilling manually use core bits that cut easily and have a low specific initial pressure.
Take care that the segments jut out sufficiently against the tube.
It is useful to apply some water resistant grease to the thread of your tool so it can be taken off again
more easily.
Take care that the radial run out at the diamond segments of the core bits is not more than 1 mm.
Only use suitable wrenches for changing the core bit. Thereby hold the drilling spindle with another
wrench.
Never use a hammer or something similar to open the core bit. If necessary elongate the
wrench.
