A.2.4.4
Lamp position control mode
The position of the lamps and their maximum travel distance can easily be checked
through the values shown in the keyboard display in this control mode.
The scanner must be in the “lamp initialization mode”. To switch the scanner to the “lamp
initialization mode”, use the key combination as described in chapter A.2.4.1.
+
Press the left or right up key together with the cradles up key
or
+
press the left or right down key together with the cradles down key
The display will change to the “lamp position control mode”.
The display shows two values for each lamp:
SW:
<value>
Shows the current rotation angle of the lamp, measured from the position of the reference
switch. The position that activated the reference switch is defined as the zero point for the
lamp movements.
ABS:
<value>
Shows the angle the lamp has moved after pressing the button combination. It is assumed
that the lamps have been manually adjusted to be optically straight as described in
chapter A.2.4.1
With the key combination described above, the lamps will move at a higher speed than
with the up key or down key only.
In this mode, the lamps can be moved to their maximum positions for testing purposes.
The function of the home position switch and its position can also be tested in this mode.
NOTE:
If the lamp is moved beyond its normal maximum position, the scanner plays the
warning sound:
“Attention”
This lamp position can not be saved for safety reasons.
This mode ends automatically after a short time-out period or directly after pressing the
STOP
button on the scanner keyboard.
The lamps must be able to freely move within an angle of +/- 45° before they touch their
corresponding mechanical end position. The minimum requirement is that they move 45°
in the direction of the scanning bed; a limitation in the other direction can be tolerated. If
that limitation exists on one lamp, they can also be swapped to continue working with the
scanner.
The reference switch position is also of importance. The switch should be activated shortly
before the lamp is blocked. A distance of an angle of 2 – 4° is ideal, higher values are no
concern, lower values must be corrected. The correction is done by bending the sheet
metal piece that activates the switch.
