Important information
DANGER
Dangerous state of the machine
b
Make sure that the dangerous state of the machine is (and remains) switched off
during the alignment process.
b
Make sure that the outputs of the safety light curtain do not affect the machine
during the alignment process.
Prerequisites
•
The twin sticks are correctly mounted
Approach
1.
Switch on the voltage supply for the safety light curtain.
✓
During initial commissioning, the COM LED flashes white and the two twin sticks
establish communication
2)
.
2.
Align the two twin sticks with one another so that LED 1 lights up blue as well.
✓
The two twin sticks start communicating with one another. During initial commis‐
sioning, the COM LED goes out after the communication phase (about 3 s). The
alignment can now be optimized.
3.
Align the two twin sticks with one another so that at least 3 but as many as possi‐
ble of LEDs 1 to 5 light up blue.
In a cascaded system, the host remains red even if the alignment is sufficient until
all guest are sufficiently aligned.
When the maximum protective field width is utilized, the system might show mod‐
erate alignment quality during alignment with only 3 blue LEDs. The system still
has a reserve of 30 %.
4.
If the alignment quality is sufficient for 2 min, the system switches alignment
mode off. LEDs 1 to 5 go out.
5.
If the alignment needs to be redone, switch the voltage supply of both twin sticks
off and back on and continue from step 2.
6.
Finally, fasten the safety light curtain.
✓
The alignment of the twin sticks is complete.
Complementary information
In some cases, the AR60 optional laser alignment aid can make performing the align‐
ment even easier.

2)
During the initial commissioning of a stick, the LED flashes immediately to signal the first synchronization between the sticks. For all
other power-up processes, the LED only flashes if the previous system partner does not answer within 20 s. In this case, communication
can also be established with a replacement stick.
