2D-/3D Profile Sensors
5.4 Installation
5.4.1 Electrical Connection
There are two plug connectors on the sensor. The sensor is supplied with 24V operating power via the
12-pin plug. The 8-pin socket is used for communicating process and parameters data.
There are also variants with 3 plugs. The additional 8-pin plug is used to switch the laser.
Note!
Maximum permissible length of the power supply cable is 30 m.
If the device is used outdoors, the power supply cable must be equipped with an addi-
tional, suitable shield.
5.4.2 Connecting External 24 V Laser Shutdown
In order to be able to switch the laser on and off, series MLSL2 devices with laser class 3R and 3B are
additionally equipped with 24 V laser shutdown (see section
“3.3 Connection Diagram”, page 24
shutdown must be supplied with 24 V operating voltage to this end. Switching inputs I1 and I2 enable the
laser when voltage is applied, and the circuit acknowledges enabling via the signal output (Laser off = 24 V;
Laser on = 0 V).
Note!
This device is only ready for operation if external laser shutdown has been correctly con-
nected.
5.4.3 Initial Start-Up at the PC
Connect the product to supply power (plug 1) and connect the Ethernet port (socket 2) to the PC or the
switch.
CAUTION!
Make sure that the cables have been correctly and securely connected in order to
assure error-free operation.
ATTENTION!
Risk of property damage in case of improper installation!
