Starting up the device
Leuze electronic DDLS 508 44
• Then rotate the alignment screw to the left until the last green LED on the SIGNAL QUALITY indi
-
cator switches off. Count the number of rotations.
• Then rotate the alignment screw half the number of rotations that was counted to the right again.
Data transmission is now vertically aligned in the exact center.
• Rotate the lower alignment screw to the right until the last green LED on the SIGNAL QUALITY indi
-
cator switches off (see figure 4.5).
• Then rotate the alignment screw to the left until the last green LED on the SIGNAL QUALITY indi
-
cator switches off. Count the number of rotations.
• Then rotate the alignment screw half the number of rotations that was counted to the right again.
Data transmission is now horizontally aligned in the exact center.

Go to the second device. There, the ADJ (Adjust) operating mode is activated.
• Adjust the second device in the same way that the first device was adjusted.
• First align data transmission vertically, then horizontally.
Both devices are optimally aligned for the current distance.

Repeat the process several times if necessary starting with the second step, until the maximum trans
-
mission distance is reached.

Activate the AUT (Automatic) operating mode on both devices (see chapter 6.1 "Setting the operating
mode").
The devices are now ready.
6.2.3 Fine adjustment without the single-handed adjustment (SHA) process
For fine adjustment without the SHA process, two people are needed. Both people must communicate with
one another.
• One person monitors the stationary device.
• The second person monitors the mobile device.

Activate the AUT (Automatic) operating mode on both devices (see chapter 6.1 "Setting the operating
mode").

Move the travel axis or lifting axis in the direction of maximum distance.
The person at the mobile device and the person at the stationary device each monitor the respective
SIGNAL QUALITY indicator.

Stop the axis as soon as the SIGNAL QUALITY indicator on either of the devices no longer shows any
green LEDs.

Adjust the mobile device if the stationary device shows a reduced received signal level
(SIGNAL QUALITY).
• Rotate the upper alignment screw to the right until the last green LED on the SIGNAL QUALITY indi
-
cator switches off at the mutually opposing device (see figure 4.7). To do this, communication with
the second person is required at the mutually opposing device.
Note: The second person on the mutually opposing device notifies you of their “Signal Quality” indi
-
cator.
• Then rotate the alignment screw to the left until the last green LED on the SIGNAL QUALITY indi
-
cator switches off. Only count the number of rotations.
NOTICE
Alignment for maximum transmission distance

The procedure must be carried out for the last time starting with the fourth step for the maximum trans
-
mission distance.
Only then are the devices optimally aligned with each other.
At the maximum transmission distance, the SIGNAL QUALITY indicator may be one or two green
LEDs short of end-scale deflection. Data transmission is, however, still active.
