EZ-SCREEN
Instruction Manual
Setting cascaded sensors for scan code, trip or latch output,
external device monitoring (EDM), reduced resolution, fixed
blanking and inverted display is identical to the procedure for
non-cascadeable emitters and receivers (see Section 4).
Scan codes for each emitter and receiver pair must match.
However, for cascaded installations, scan codes must alternate
on adjacent systems as described in Section 3.1.8 and Figure
3-8. See warning below.
While the scan code, reduced resolution, fixed blanking, and
inverted display settings are independent for each cascaded
sensor pair, the trip/latch mode and EDM settings must be
determined by the first receiver in the cascade (closest to the
machine interface), which controls the OSSD outputs. All other
receivers in the cascade must be set for trip mode and
2-channel EDM (factory default settings).
The settings on the first receiver then determine trip or latch
mode and 1- or 2-channel EDM/aux. output, and this is the only
receiver that requires a reset following a latch condition.
One or more areas within any cascaded EZ-SCREEN sensor
pair can be blanked out, just as with other EZ-SCREEN light
screens. Each sensor pair within a cascade must be
programmed separately, if required. See Section 3.4.3 for
more information and programming procedure.
Each cascaded system must be configured, before it can be run
in a production environment.
Before configuration, install all emitters and receivers per
Sections 3 and 7. The last receiver must be terminated
either with a terminator plug or by connecting two closed
mechanical contacts (see Sections 7.8 and 7.9).

In situations where multiple systems are mounted closely
together, or where a secondary emitter is in view (within ±5°),
within range of an adjacent receiver; the adjacent systems must be
configured for different Scan Codes (i.e., one system set for Scan
Code 1 and the other for Scan Code 2).
If not, a receiver may synchronize to the signal from the wrong
emitter, reducing the safety function of the light screen.
This situation will be discovered by performing the trip test
(see Section 3.4.3).
