X-ray tube start-up modes

The system can make exposures using two start-up modes, when pressing the
exposure button in preparation stage:
• Low speed start-up that boosts the tube anode to ca. 3000 rpm.
• High speed start-up that boosts the tube anode to ca. 9000 rpm.
No more than four high-speed start-ups are allowed per minute. An error
is indicated if the number is exceeded.
High speed start-up is available during no more than 30 seconds. After that
period the rotation speed will be reduced to low speed.
After the exposure and when the exposure button is released, the tube anode
is braked automatically.
When the X-ray tube anode is rotating with high speed the generator must not
be turned off. Please wait until the system is on low speed before switching
the generator off. The bearings of the X-ray tube can be damaged if the
generator is switched off before the anode is braked.
