Instruction Manual
1. Introduction — Overview
1.1 System Description
The Banner EZ-SCREEN™ Grid System is an optically synchronized,
microprocessor-controlled, opposed-mode optoelectronic “light grid.” 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 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
3-17 and 3-18 for more information.)

Each EZ-SCREEN Grid 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 57-58 for quick-disconnect options.
