key manipulation is ignored.
Flashes when control is possible both via keyboard and the RS 232 interface.
POWER green Lights when mains power supply is on.
NORMAL green Lights during normal operation, speed is above 95 % of the target speed
Flashes in case of acceleration, braking and “OVERLOAD”.
FAILURE red Lights in case of failure.
Flickers in case of current peaks within the magnetic bearings.
HEATING green Lights when heating is on.
only on NT 340 M Flashes when heating has been preselected.
