SICK MLG-2 Pro

This distance also applies to reflective surfaces located next to the light grid (parallel to
the sending/receiving axis).
4.3 Mounting procedure
b
Mount the sender and receiver at the same height. For minor adjustments when
aligning, the sender and receiver can be adjusted in the brackets.
b
If possible, mount the top bracket at a height such that the offset in the housing of
the MLG-2 sits on the bracket. This prevents the MLG-2 from sliding down.
Figure 32: The sender and receiver are aligned incorrectly
The end with the cable connection must point in the same direction for both devices.
Sender and receiver must not be installed at 180° rotated relative to each other.
Tighten the screws used to mount the bracket to a torque of 5 to 6 Nm. Tighten the
screws used to secure the MLG-2 in the bracket to a torque of 2.5 to 3 Nm. Higher tor‐
ques can damage the bracket while lower torques do not provide adequate fixation to
prevent the MLG-2 from moving in the event of vibrations.
When mounting, make sure that sender and receiver are aligned correctly. The optical
lens systems of sender and receiver must be located opposite one another. If neces‐
sary, use a water level to check the components are parallel.
4.3.1 Mounting the QuickFix bracket
QuickFix brackets can be mounted in two ways:
•
On the side
•
On the back
The two mounting surfaces for the brackets of the sender or receiver must not be
angled more than ±2° to each other. If this is not possible, use the optional FlexFix
bracket.
Mounting the QuickFix bracket on the side of a machine or profile frame
Up to a monitoring height of 2 m, the sender and receiver are mounted with two Quick‐
Fix brackets each.
For a monitoring height of more than 2 m, the sender and receiver are mounted with
three QuickFix brackets each.
