3 - 40 Machine Maintenance 704-0212-209 VM Series Maintenance and Safety Manual
Other possible messages during initialization usually indicate missing or corrupted files.
The usual solution for such problems is to restore or delete files. For help solving these
problems, contact your local Hurco service representative.
Error Messages
If errors occur after power up, take careful note of any error messages on the screen.
Note if the red beacon is on or flashing when the error occurs. Also, note if the control
responds to any key, button, or touchscreen selection after the error occurs.
Corrective Measures
One or more of the following corrective measures may be necessary:
Check Wiring
Perform these checks:
• Trace the wiring as far as possible.
• Wiggle connectors and ensure they are properly seated.
• Test the connections with an ohmmeter.
• Unplug and reseat circuit boards; sometimes connectors become tarnished
and do not conduct well. If the contact points on a printed circuit board (PCB)
are dull looking, polish them with a rubber eraser.
Perform a Reset
Technical assistance personnel may ask you to reset a circuit board or the machine.
• To reset a PCB, press the board reset button, if present.
• To reset the machine, switch the main power off and then back on.
Swap Out a Printed Circuit Board
If the PCB is bad or has an intermittent problem, or the connector on the board is not
making sufficient contact, then take the PCB out, clean the contacts with a rubber eraser,
and reinstall it, taking care to reseat it firmly. If the error is not corrected, remove the
board and replace it with a fresh PCB.
Before calling a Hurco service representative for assistance, always
switch off the control at the power button, wait a few minutes, and
then power on again.
If an error message appears, write down the entire message before
calling a Hurco service representative for assistance.
Turn off machine power before checking the circuit boards.
DO NOT perform any circuit board work with the power on.
Be sure to wear a static-sensitive strap (grounded to the electrical
cabinet) before handling any PCB.
