POC Type 4 GuardShield Standard, Remote Teach & Cascadable Safety Light Curtains

Description

Standard GuardShield

The Allen-Bradley Guardmaster GuardShield safety light curtain is an economical, fully featured, Type 4 safety light curtain in a uniquely

styled housing. GuardShield safety light curtains are general-purpose presence sensing devices designed for use on hazardous machinery

providing point of operation, as well as perimeter and access guarding. This self-contained, two-box, safety light curtain has DIP-switch

selectable operating modes and is available in both 14 mm and 30 mm resolutions.

Modes of operation such as fixed and floating blanking, beam coding, start/restart interlock, external device monitoring (EDM), and machine

test signal, are selected by DIP-switch settings. These DIP-switches are located beneath a security door, which are conveniently located on

both the transmitter and receiver end caps.

The GuardShield’s torsionally rigid, extruded aluminium, polyurethane powder‐coated housing, combined with an environmental rating of

IP65, allows the GuardShield to be used in guarding applications across a broad range of industries.

Remote Teach GuardShield

The GuardShield Remote Teach system provides a remote means of changing a fixed blanking configuration within the GuardShield

safety light curtain. This keyswitch box eliminates the need to open the GuardShield receiver door and perform the Teach function.

The three-position key switch simulates the opening of the GuardShield receiver door, teaching the GuardShield light curtain the new

fixed blanking area, closing the door and returning to the run mode of operation.

The IP65 rated key switch box is provided with a steel mounting back plate to facilitate mounting of the box in proximity to the

GuardShield receiver. It is necessary to see the receiver LEDs when performing the teach function.

Cascadable GuardShield System

A cascadable GuardShield safety light curtain is a standard GuardShield safety light curtain in 14 and 30 mm

resolutions with additional M12 connectors located on top of each safety light curtain. The connector on the

top of the safety light curtains allow the interconnection of up to a total of three pair of GuardShield safety

light curtains with a common pair of OSSDs. The ability to interconnect GuardShield pairs reduces overall

system wiring and simplifies the safety circuit resulting in a lower overall cost of a multiple safety light

curtain system. This product configurability also allows a GuardShield safety light curtain system to protect

multiple sides of a machine or simply adds flexibility when positioning GuardShield in various applications.

The complete cascading GuardShield system has the full functionality of a standard GuardShield (beam

coding, EDM, start/restart interlock, fixed and floating blanking). There are a couple of operating modes

which can not be configured in the middle and end segments (EDM and Start/Restart Interlock) and must

only be configured in the host (first) pair. The system will still have these operating modes active if

configured in the host or first GuardShield pair. This host or first pair is the pair of cascading GuardShield

light curtains, which have the output cordsets connected and wired to the safety relay, safety PLC or FSDs. Configuring of the EDM operating mode in the end and

middle segments will cause the system to go to a lock-out condition after the first interruption of the sensing field. Configuration of the start/restart interlock

operating mode in the end and middle segments will cause the system to stay in a red condition awaiting reset after the interruption of the sensing field.

The cascading GuardShield safety light curtains are ordered as pairs (transmitter and receiver) and are shipped under one cat. no. After selecting the appropriate pair

of cat. nos. for a cascading GuardShield system, select the interconnecting transmitter and receiver patchcord cat. nos. to connect the GuardShield pairs. The

transmitter patchcord is a 4-pin M12 patchcord offered in lengths of 1/3 meter, 1 meter and 2 meters. The receiver patchcord is an 8-pin M12 patchcord offered in

lengths of 1/3 meter, 1 meter, and 2 meters.

If the end pair of a cascading system is a cascading pair of GuardShield light curtains, it is necessary to attach a termination adaptor to the top M12 connector located

on the receiver. Be sure to order all other required interfaces and accessories.
