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 Activate the MAN (Manual) operating mode on both devices (see chapter 6.1 "Setting the operating
mode").
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").
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.
