Fine Adjustment Without The Single-Handed Adjustment (Sha) Process - Leuze electronic DDLS 508i Original Operating Instructions

Starting up the device
NOTICE
If the MAN operating mode (manual) is activated on both devices, the mutually opposing device
is also switched to the ADJ operating mode (alignment) upon switching to the ADJ operating
mode (alignment).
Adjust the first device as follows:
Ä Rotate the upper alignment screw to the right until the last green LED on the SIGNAL QUALITY indica-
tor switches off (see chapter 3.1.1 "device construction").
Ä Then rotate the alignment screw to the left until the last green LED on the SIGNAL QUALITY indicator
switches off. Count the number of rotations.
Ä Then rotate the alignment screw half the number of rotations that was counted to the right again.
ð Data transmission is now vertically aligned in the exact center.
Ä Rotate the lower alignment screw to the right until the last green LED on the SIGNAL QUALITY indica-
tor switches off (see chapter 3.1.1 "device construction").
Ä Then rotate the alignment screw to the left until the last green LED on the SIGNAL QUALITY indicator
switches off. Count the number of rotations.
Ä Then rotate the alignment screw half the number of rotations that was counted to the right again.
ð Data transmission is now horizontally aligned in the exact center.
Go to the second device. There, the ADJ (Adjust) operating mode is activated.
Ä Adjust the second device in the same way that the first device was adjusted.
Ä First align data transmission vertically, then horizontally.
ð Both devices are optimally aligned for the current distance.
Ä Repeat the process several times if necessary starting with the second step ("Travel command for
travel axis or lifting axis") until the maximum transmission distance is reached.
NOTICE
Alignment at maximum transmission distance!
Ä At the maximum transmission distance, The procedure must be carried out for the last time
starting with the fourth step ("Operating mode ADJ"). Only then are the devices optimally
aligned with each other.
Ä Activate the AUT (Automatic) operating mode on both devices (see chapter 6.1 "Setting the operating
mode").
ð The devices are now ready.
NOTICE
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.
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.
Ä Activate the AUT (Automatic) operating mode on both devices (see chapter 6.1 "Setting the operating
mode").
Ä Move the travel axis or lifting axis in the direction of maximum distance.
ð The person at the mobile device and the person at the stationary device each monitor the respec-
tive SIGNAL QUALITY indicator.
Ä Stop the axis as soon as the SIGNAL QUALITY indicator on either of the devices no longer shows any
green LEDs.
