官方故障排除步驟
[Cause of error] The machine tool builder can use a master keyword (general key) for putting the control into service that will unlock all options for a duration of 90 days. This message is displayed after every start-up if the general key is active. After the time period is over, the options can be used only with the fitting keywords. If an NC program is running when the general key expires, an NC stop is issued! [Error correction] Contact the machine manufacturer. He can check in the SIK menu how long the general key will be valid, or deactivate the general key.
