6.4.5 Fault Output
The current sourcing (PNP) solid-state output (70 mA maximum) is used for control functions that are not safety related; a
typical use is to signal a lockout (fault) to a programmable logic controller (PLC). Available on both the receiver and emitter,
the output provides a fault signal (lockout = On). Interrupting (blocking) the sensing field is not considered a lockout, so the
Fault Output does not change state.
This feature is available only when an 8-conductor interface is used.
6.4.6 Scan Code Select
Emitter and receiver models interfaced with 8 conductor cables may be configured to one of two Scan Codes (1 or 2). A
receiver recognizes light only from an emitter with the same scan code. The scan code is configured at power-up and
remains set until the input is changed and power is cycled.
•
Select Scan Code 1 by connecting pin 8 (violet wire) to 0 V DC or leaving it open (not connected). Prevent unused
wires from shorting to ground or to other sources of energy (for example, terminate with wire-nut).
•
Select Scan Code 2 by connecting pin 8 (violet wire) to +24 V DC.
Both the emitter and its corresponding receiver must have the same setting. Emitter and receiver models interfaced with 5-
conductor cables are always configured for Scan Code 1.
6.4.7 Preparing for System Operation
After the initial trip test has been accomplished, and the OSSD safety outputs and EDM connections have been made to the
machine to be controlled, the EZ-SCREEN LS Basic is ready for testing in combination with the guarded machine.
The operation of the EZ-SCREEN LS Basic with the guarded machine must be verified before the combined System and
machine may be put into service. To do this, a Qualified Person must perform the Commissioning Checkout Procedure (see
on page 56).
6.4.8 Sensor Interchangeability
The figures and table below illustrate a wiring option that provides sensor interchangeability (or swapability)—the ability to
install either sensor at either QD connection.
The resulting installation provides the ability to swap the emitter and receiver position. This wiring option provides
advantages during installation, wiring, and troubleshooting.
To use this option, connect all emitter wires in parallel (color-for-color) to the receiver cable via individual wires or the CSB..
splitter cordset (can be used with only emitters and receivers with similar connectors, such as a pair with 8-pin quick
disconnects or a pair with 5-pin quick disconnects.).
Model CSB.. splitter cordsets and DEE2R.. double-ended cordsets allow easy interconnection between an EZ-SCREEN LS
Basic receiver and emitter, providing a single homerun cordset.
