EZ-SCREEN LP
Instruction Manual
Installation and Alignment
3.3 Initial Electrical Connections
Lockout/tagout procedures may be required (refer to OSHA
29CFR1910.147, ANSI Z244-1, 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 earth ground (green/yellow
wire, see Figures 3-23 through 3-26). Do not operate the
EZ-SCREEN LP System without an earth ground connection.
See the warning at right.
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 via RD or pigtail QD
connections.
Emitter Cordset
EZ-SCREEN LP emitters use an 8-pin cordset, but not all
conductors are used. The other wires are in place to allow a
parallel connection (color-for-color) to the receiver cable (see
Figure 3-22), providing sensor interchangeability (or “swapability”);
either sensor may be installed at either cordset connection.
In addition to providing similar cabling, this wiring scheme is
advantageous during installation, wiring, and troubleshooting.
Receiver Cordset
Do not connect any wires to the machine control circuits
(i.e., OSSD outputs) at this time. For the initial power-up and
checkout, NO EDM must be configured. Locate the orange and
orange/black wires (pins 2 and 3) and temporarily connect the
ends of the wires to each other (but not to the machine at this
time). Take precautions to prevent the wires from shorting to
ground or to other sources of energy (e.g., terminate with the
included wire-nut). Final EDM wiring must be completed later.
If used, connect the external reset switch to the reset wire
(violet) on the receiver cable and to 24V dc (see Figures 3-24
and 3-26). See warning in Section 3.1.3 about the physical
location of the reset switch. The reset switch must be a normally
open switch that is held closed for approximately 1/4 second,
but no longer than 2 seconds, and then re-opened to accomplish
the reset. The switch must be capable of switching 10 to 30V dc
at 30 mA.

total load current (OSSDs + Aux)
NOTE: Maximum cordset lengths are intended to ensure that
adequate power is available to the EZ-SCREEN LP when
the supply is operating at +24V dc – 15%.

WARNING . . .
Proper Electrical Hookup
Electrical hookup must be made by Qualified Personnel
and must comply with NEC (National Electrical Code) and local
standards.
Make no more connections to the EZ-SCREEN LP System than
are described in Sections 3.3 through 3.5.5 of this manual.
Connection of other wiring or equipment to the EZ-SCREEN LP
System could result in serious bodily injury or death.
