Pin Assignment - SICK DME 3000-2 Betriebsanleitung

The metal housing of the DME 3000 does not have any direct coupling to the cables, which lead out at
the attachment plug (supply voltage-plus, supply voltage ground, switching outputs Q1 and Q2,
Profibus signals A and B, Profibus terminator supply voltage 5 V and GND). The shields of both
Profibus cables are connected via the DME 3000 connecting lead. A connection between the Profibus
shield and the metal housing of the DME 3000 does NOT exist to prevent ground loops.
To achieve better shield effectiveness in environments with strong interference and still prevent the
ground equalizer current from flowing via the shield of the Profibus cable, the metal housing of the
DME 3000 and the control cabinet ground should be connected via a ground cable. This provides
higher shield effectiveness and separates the ground equalizer current from the Profibus cable.

Using a cable adapter, the 12-pin attachment plug (M18 housing) of the DME 3000 is split among
three cable connectors (each in M12 housing):
•
Bus input (A and B cables)
•
Bus output (A and B cables, 5 V supply voltage)
•
DME 3000 supply voltage, two switching outputs
Confusing the normal sensor plug and the Profibus-DP plug is impossible due to different connector
housing.
Bus output:
5-pin M12, female

The supply voltage to be connected for the DME 3000 (pin E, pin M) and the 5 V supply voltage (pin
E,J, pin F,H) supplied by the DME 3000 are indirect coupled. The switching outputs Q1 and Q2
connect to pin M. The Profibus data cables connect to pins F and H.
