SICK MLG-2 ProNet - Mounting the Quickfix Bracket

Figure 34: 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
torques 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 (see "Accessories", page 170) 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
QuickFix brackets each.
For a monitoring height of more than 2m, the sender and receiver are mounted with
three QuickFix brackets each.
The QuickFix bracket consists of two parts, which are pushed into each other. An M5
screw is used to join both parts and to clamp the housing (sender or receiver).
Mounting can be carried out in two ways:
•
With the M5 screw through the QuickFix bracket to the machine or profile frame. A
screw nut or threaded hole is required on the machine or profile frame.
•
With the M5 screw through the machine or profile frame to the QuickFix bracket. A
screw nut is required for each QuickFix bracket.
When choosing the length of the M5 screw (hexagon head or cylinder head screw),
consider the QuickFix bracket and the machine or profile frame.
