Lockout/tagout procedures may be required (refer to OSHA1910.147, ANSI Z244-1, ISO 14118, or the appropriate
standard for controlling hazardous energy). Following relevant electrical standards and wiring codes, such as the NEC,
NFPA79 or IEC60204-1, always connect the earth ground (green/yellow wire). Do not operate the EZ-SCREEN Type 2
without an earth ground connection.
Make the electrical connections in the order described in this section. Do not remove end-caps; no internal connections are
to be made. All connections are made through the M12 Euro-style quick-disconnects.
Emitter Cordset
Receiver Cordset
EZ-SCREEN Type 2 emitters have an 8-pin cordset, but only three
conductors are required:
•
Brown = +24 V dc
•
Blue = 0 V dc
•
Green/Yellow = GND
Do not connect any wires to the machine control circuits (that is,
OSSD outputs) at this time.
For the initial checkout, only the following EZ-SCREEN Type 2 receiver
conductors should be connected:
•
Brown = +24 V dc
•
Blue = 0 V dc
•
Green/Yellow = GND
Additionally, connect the external reset switch, if used, or test signal
contact to the Reset/Test wire (violet) and to 24 V dc.
NOTE: The reset switch must be a normally closed switch that is held open for approximately 1/4
second, then closed to accomplish the reset. The switch must be capable of switching 10 to 30 V dc at
30 mA.
The other wires are for an optional hookup that allows for parallel connection (color-for-color) to the receiver cable. This
optional hookup provides for sensor interchangeability (or swapability) that facilitates installing either sensor at either QD
connection. Besides providing similar cabling, this wiring scheme is advantageous during installation, wiring, and
troubleshooting.
