3.15 Check and Adjustment of Original Guide Sensors (ATAC)
The Original Guide Sensors are located under the Top Profile of the Original Guide. To get
access to the sensors:
Remove the Ruler from the Original Guide.
Remove the 4 fixing screws behind the Ruler.
Remove the Top Profile from the Original Guide.
Notes:
1) All sensors are click-mounted on brackets, the position of the ATAC sensor bracket is
secured by means of two fixing screws. To make the sensor adjustment easier, the left fixing
screw goes through round hole and the right through an oblong hole.
The bracket for the motor (tacho) sensor is secured by only one fixing screw
2) For safety reasons, the current of the Elevation Motor is constantly monitored, and if the
currents exceeds a predetermined value, the drive circuit will be switched OFF and the motor
stops and can no longer be controlled from the Operator Panel.
To reset the OFF condition, the power must be removed from the MDA Board, either by
disconnection of the power cable (connector J1 on MDA) or by switching the scanner
OFF/ON.
3) When moving the Original Guide towards ”top position”, the motor should be stopped
before the spindle-nut reach the left end of the spindle, allow for a spacing of about 1-2 mm
as shown in Fig. 3-26, page 74. If the UP Key is pressed until the spindle-nut hits the end-stop
of the spindle, the motor will be switched OFF by the current limit circuit and can no longer
be controlled from the Operator Panel, see note 2).
