2. Introduction

GuardShield Safe 2 safety light curtains are active

optoelectronic protective equipment (AOPE) type 2

and comply to annex IV of the European Machinery

Directive EC/98/37 and IEC 61496 as a safety

component.

The

GuardShield Safe 2 is offered with a 30mm

resolution in Guard Only mode.

2.1. System design

GuardShield Safe 2 safety light curtains consist of a

transmitter and a receiver, each having a standard

built-in intelligent laser alignment system ILAS.

(Figure 1).

This

allows a much easier adjustment during installation

and system testing compared to conventional safety

light curtains.

Figure 1: Main system parameters

The products are a modular construction housed in a

very compact and sturdy extruded aluminium proﬁle.

2.2. Special features

The

outstanding features of the safety light curtain

systems of GuardShield Safe 2 are:

Integrated self test mode, which make an

external testing unnecessary

Conﬁgured with intelligent laser alignment

ILAS

Hand protection (30 mm resolution)

Wide dynamic

range with a compact proﬁle

type: 30 mm resolution: 0 m up to 6 m operating

range,

Max. 256 beams per system

Tolerant to dust, dirt, pollution

Short circuit protected semiconductor outputs

Electrical interface compatible to industry

standard

Built-in diagnostic LED or optical interface for

quick trouble shooting

Very compact design: 30 x 40 mm (1.2” x 1.6”)

Wide standard product range for resolution,

protective height, type of application

Optical synchronisation, no electrical cable

needed between transmitter and receiver

Maintenance-free and cost effective

3. Applications

3.1. Typical applications

Depending on the risk analysis GuardShield Safe 2

systems are used for (Figure 2):

Entry / exit safeguarding

Point-of-operation safeguarding

Hazards area safeguarding
