SICK ZLD18 - 3 Product description; 3.1 Operating and status indicators

Explanation of connection terminology used in Tables 1-3:
BN = Brown
WH = White
BU = Blue
BK = Black
n. c. = no connection
Q1 = switching output 1
Q2 = switching output 2
L+ = supply voltage (Uv)
M = common
L.ON = light operate
D.ON = dark operate
NOTE
The sensor outputs may come equipped with a factory set ON delay and/or OFF delay.
This is indicated by a Txx suffix at the end of the Model Number (Zxx18-xxxxxxTxx).
