6.1. General Information
This chapter describes some of the faults that may occur and how
to deal with them. If the fault cannot be dealt with, or if there are
other faults, contact your nearest retailer. See Contact Information
at the front of the manual.
6.1.1. The machine will not start
• Check if the emergency stop switch on the control panel is
pressed. Reset the switch by turning it 45°.
• Check if the power connection is correct. Check that there
is full voltage available on the supply's phase/phases.
• Check the fuses and contactors in the electrical cabinet.
• Check the error code on the frequency converter's display.
For corrective measures, see chapter Electronic error
codes on page 30.
6.1.2. The machine vibrates or wears the tool unevenly
• Check that there is movement between the chassis and
grinding head. If necessary, loosen one of the two pins
in order to increase the play between the chassis and the
grinding head.
• Check the belts, replace if necessary.
• Check the condition of the grinding holders. If the grinder
holders need reconditioning, contact HTC for information
about spare parts.
6.1.3. The machine is grinding at an angle
• Recondition the grinding holder. See under The machine
vibrates or wears the tool unevenly on page 28.
• Check that the upper belt is undamaged. Try to turn the
large disc in one direction or the other, there should be
resistance. If it turns freely, the belt is broken and must be
replaced.
6.1.4. The machine stops during operation
• Check the error code in the display on the frequency
converter, see Electronic error codes on page 30.
