EZ-SCREEN Point
Instruction Manual
Overview
1.1 Introduction
The Banner EZ-SCREEN™ Point System creates an optically
synchronized, microprocessor-controlled, opposed-mode
optoelectronic light beam. This economical two-part system
consists of an emitter and receiver. The system requires
no external controller or sync wire between the emitter and
receiver; the microprocessors are located within the receiver.
The receiver has two diverse-redundant, solid-state safety
outputs to control 24V dc loads. If an ac-powered MPCE or
other load is required, an accessory interface module may be
used to convert the EZ-SCREEN dc outputs to isolated, forced-
guided relay contacts. (See Section 2.2 and Figures 3-20 and
3-21 for more information.)

Each EZ-SCREEN Point System
needs only an emitter and a
receiver. Optional Interface Module
is available for switching ac or larger
dc loads . (See Section 2 .2 for more
information on the Interface Module.)
See pages 59-60 for quick-disconnect options.

1. Overview
EZ-SCREEN™ Point typically is used in combination with
additional components to create a “light grid,” for guarding the
perimeter around a dangerous machine, or to guard the access
to such an area . These components may be mirrors (as is used
in the ACCESS-GUARD kit), or they may be other single- or
multiple-beam systems, combined to create a customized light
grid .
The EZ-SCREEN Point System is available as a sensor pair,
or as part of an ACCESS-GUARD configuration. Emitters are
available in short-range and long-range versions; receivers are
the same for all emitters . (Long-range sensors are not suitable
for use with the ACCESS-GUARD configuration.) Emitters and
receivers do not need matching serial numbers to work together.
