NOTICE
If, while selecting a new operating mode, the operating mode selector switch [MODE] is not
pressed for a longer period of time (> 10 s), the previously activated operating mode remains
active.
6.2
Fine adjustment
6.2.1
General procedure
Fine adjustment of the data transmission must be carried out after installation.
Prerequisites:
• The devices are mounted mutually opposing one another, are electrically connected and are roughly
aligned (see chapter 4 "Mounting").
• The devices are opposite one another at a close distance (> 1 m). The SIGNAL QUALITY indicator
shows at least one or two green LEDs on both devices.
Perform fine adjustment
There are two processes for performing the fine adjustment:
• The patented single-handed adjustment (SHA) procedure makes it possible for a single person to moni-
tor the "Signal Quality" and adjust the transmitter (see chapter 6.2.2 "Fine adjustment with the single-
handed adjustment (SHA) process").
• The alternative procedure requires two people (see chapter 6.2.3 "Fine adjustment without the single-
handed adjustment (SHA) process").
• One person monitors the "Signal Quality".
• The second person adjusts the transmitter at the mutually opposing device.
Decide which of the two processes to use; explanations can be found in the following chapters.
6.2.2
Fine adjustment with the single-handed adjustment (SHA) process
The SHA process is a standard function that is implemented in every device. With the SHA process, you
can perform the fine adjustment with just one person.
Ä
Ä
Enter a travel command for the travel axis or lifting axis to the end of the transportation path or move
the axis manually or in automatic mode to the end of the transportation path.
Ä
Data transmission is automatically deactivated when the last green LED in the SIGNAL QUALITY dis-
play goes out.
ð
The travel axis or lifting axis is normally stopped automatically if data transmission is interrupted. If
not, stop the axis manually.
ð
One orange LED must still be illuminated in the SIGNAL QUALITY indicator.
Ä
Activate the ADJ operating mode (alignment) (see chapter 6.1 "Setting the operating mode").
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", point 11).
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.
