2.14 Starting of Tomo

Attention: When mounting a Bucky Wall Stand right hand please install software before switching-on the equipment. Please follow chapter 3.9.

When switching on the unit it checks automatically after initialisation of the control to duck that all axis are in zero position. The axis will correct themselves in millimetre range, if they are not on the rotation resistor index but in near to the zero point. A preparation drive is required as soon as the zero point range has been left to ensure that in case of overflow of the index marks in the zero position the indicators will be set accordingly. In this case all three operating methods SIDs on the control handle will flash on and the preparation drive will be activated while pushing the PREP-switch. After that the unit will be in table mode. Do not push the emergency-stop while performing the drive and adjust the vertical first draw SID to avoid any collision.
