HTC 650 RX Troubleshooting
5.0 35
6.6 The machine stops - manual operation
• Check the error code in the display on the frequency converter, see Electronic
error codes, page
36 .
6.7 The machine stops - radio control
Other equipment can interfere with the radio traffic between the machine and the radio
control unit, which means that the communication error indicator (ComError) can start
to blink on and off. When the contact between the machine and the radio control has
been broken for too long the machine stops for safety reasons.
• Check if the communication error indicator (ComError) blinks.
• Restart the machine and switch off any interfering equipment.
• Check the error code in the display on the frequency converter, see Electronic
error codes, page
36 .
6.8 The fuse trips frequently
• The load is too high on the distribution box to which the machine is connected.
Use a different socket or reduce the speed of the machine.
• Check the tools. Ensure that the correct tools are used, that they are in working
order and that they are correctly fitted.
6.9 The machine cannot cope
• Heavy load. Press the handle down slightly so that the grinding head eases
slightly away from the surface being ground..
• Sticky coating on the surface being ground. Run half of the machine on the
surface to be cleaned and half on the clean surface. This removes any residue
from the tools.
• Check the tools. Ensure that the correct tools are used, that they are in working
order and that they are correctly fitted.
• Voltage drop. Check that the cable area meets HTC's recommendations.
Tip!
Check the minimum recommended cable area before using an extension cord.
You will find the recommended cable area under Technical Data.
