EZ-SCREEN® AC Interface Box

Overview

The EZ-SCREEN AC Interface Box (EZAC Series) is powered by 100-250V ac.

EZAC-R.. models can supply one EZ-SCREEN receiver, a single emitter-receiver pair, or two cascaded emitter-receiver pairs; see Figure 4. Emitter-only models (EZAC-E..) can supply up to four cascaded emitters, and have no output circuitry.

The integrated interface module, located on a replaceable PC-board, converts the EZ-SCREEN receiver OSSD output signals into isolated redundant output channels with an 8 amp / 250V ac/dc switching capacity for ac or dc safety circuits (see Models on page 1 for output descriptions). The outputs of the interface module follow the action of the EZ-SCREEN OSSD outputs, with a 10 millisecond response time in turning OFF, and approximately 10 millisecond delay in turning ON. All models feature external device monitoring (EDM) in the form of 1-Ch, 2-Ch or power monitoring.

All models have one 8-pin M12 Euro-style QD to connect to the EZ-SCREEN receiver or emitter. Other connections are dependent on model; see page 1. Hookups, therefore, are also model-dependent; see pages 6-9. See pages 14 and 15 for cabling options.

Indicators

A bicolor LED indicates the output contact status of internal relays K1 and K2. (Emitter-only models have a Green Power ON/OFF indicator.)

	LED Status	Power	K1 and K2	N.O. Output	N.C. Output	Light Screen
	ON Green	ON	Energized	Closed	Open	Clear and reset

WARNING . . . This Interface Box is not a point-of-operation

guarding device, as defined by OSHA regulations.

It is necessary to install point-of-operation guarding devices, such as safety light screens and/or hard guards, to protect personnel from hazardous machinery. Failure to install point- of-operation guards on hazardous machinery could lead to serious injury or death.

Configuration

Models EZAC-R9-QE8 and EZAC-R11-QE8 can be configured for 1-Channel, 2-Channel, or No EDM. The EDM slide switch setting must match the EZ-SCREEN receiver’s DIP switch setting. For example, if the slide switch is set for “EDM 1-CH,” then “E1” must be selected on the EZ-SCREEN receiver.

Models EZAC-R8N-QE8-QS53, EZAC-R10N-QE8-QS53, and EZAC-R15A-QE8-QS53 are preconfigured. However, the EZ-SCREEN receiver’s DIP switch setting must still match the EZAC Interface EDM setting:

EZAC-R8N-QE8-QS53 – No EDM; EZ-SCREEN configuration – E2 (default) EZAC-R10N-QE8-QS53 – No EDM; EZ-SCREEN configuration – E2 (default) EZAC-R15A-QE8-QS53 – 1-Channel EDM; EZ-SCREEN configuration – E1

See Sections 3.5.3 and 4.2 of EZ-SCREEN manual (p/n 112852) for further information.

Mechanical Installation

Mount the box in a convenient location that is free from heavy impulse force and highamplitude vibration. The box and any auxiliary Reset switches must be located outside the guarded area, where the switch operator has a full unobstructed view of the entire guarded area and any associated hazards as the reset is performed. The box and any auxiliary reset switch(es) must not be reachable from within the guarded area and must be protected (through the use of rings or guards, for example) against unauthorized or inadvertent operation. See Figures 13 and 14 for dimensions and mounting hole locations.

The box is designed for mounting directly to the emitter or receiver housing, if desired. The box meets IEC IP65 standards; an additional enclosure or cabinet is not required.

EZ-SCREEN® AC Interface Box

Electrical Installation

The hookup for a particular box is dependent on the model (see Figures 5-9). For models with EDM, this should be configured before the initial checkout and use of the light screen. EDM is configured via a combination of the electrical hookup and a sliding switch inside the box (depending on model; see page 6).

All EZAC-R.. models have one 8-pin M12 Euro-style QD to connect to the EZ-SCREEN receiver and/or emitter. QD models have one 3-pin Mini-style QD for power and ground input, plus a Mini-style I/O connector (either 8-pin or 5-pin, depending on model) to connect to the safety outputs and monitoring contacts (i.e., EDM). Non-QD (hard-wired) models have two holes with 1/2" NPT threads to accommodate conduit fitting or cable gland and hard-wire cables (two cable glands and one hole plug included with box).

EZAC-E.. models have one (8-pin or 5-pin) M12 Euro-style QD to connect to the emitter, plus a 3-pin or 5-pin Mini-style connector for power and ground. Hard-wired emitter models have one hole and one cable gland.

WARNING . . . Electrical

Shock Hazard

Electrical shock hazard exists when the EZ-SCREEN AC Interface Box has power applied to it and the box cover is open. Use extreme caution to avoid electrical shock during installation or servicing, or when the box cover is open to change the switch configuration or replace the relay board module.

Always disconnect all power from the box and the guarded machine before making any connections, replacing any component, or before opening the enclosure housing of the box.

Connection to the Guarded Machine

The hook-up diagrams in Figures 5-9 show a generic connection of two safety output channels of the models EZAC-R.. AC Interface box to machine primary control elements MPCE1 and MPCE2. A machine primary control element is an electrically powered device, external to the box, which stops the machinery being controlled by immediately removing electrical power from the machine and (when necessary) by applying braking to dangerous motion.

WARNING . . . Not for Use as a Stand-Alone Safety Module

1.DO NOT connect E-stop switches, 2-hand control switches, safety interlock switches, or similar devices directly to this interface module.

2.Always connect pins 2 and 3 of the receiver/emitter M12/Euro-style QD connection to the monitoring input of the Primary Safeguarding Device that controls it (see Figure 4).

The EZAC box does not have the circuitry required to perform a self-check. A single fault inside the unit or in external devices (like switches or E-stop buttons) can go undetected and create an unsafe condition.

Failure to properly connect the EZAC box to a control-reliable Primary Safety Device could result in serious injury or death.

CAUTION . . .

Ensure Proper Monitoring

The primary safeguarding system must be capable of external device monitoring of the EZAC-R.. models, and employ a Normally Open Reset contact. Thus, the EZ-SCREEN AC Interface Box is not intended to be used with EZSCREEN Type 2 (model numbers LS2..).

WARNING . . . Electrical

Hookup

Electrical hookup must be made by a qualified electrician, and must comply with NEC (National Electrical Code) and local standards. Also, make no more connections to the EZ-SCREEN AC Interface Box than are described in this document.

Connection of other wiring or equipment to the box could result in serious bodily injury or death.
