What makes a light curtain "robust"?

KEYENCE conducted in-depth research to determine how light curtains are

damaged and learned that the most common cause is damage to the lens

surface when it is scratched, cracked, or otherwise broken due to impact from

parts or tools. In some cases, light curtains have been installed with user-

fabricated protective covers or housing to prevent this damage.

As a result of this research, KEYENCE has designed a light curtain with a

structure that prevents damage from parts or tools by narrowing the exposed

lens area and recessing it in an impact resistant housing.*

* the narrowest lens surface aperture in the industry, according to KEYENCE research as of March, 2012

Strong

Built-in guarding and the narrowest exposed lens surface in the industry.

With its narrow (9 mm wide) and recessed lens surface, the GL-R Series is protected

against impact and resultant damage from parts, tools or operators without the need for

any additional guards or covers. Additionally, the GL-R Series is protected from water and

washdown environments due to its IP65/67 enclosure ratings.

No Dead Zone

Because the rst beam is emitted

can be mounted ush inside of equipment,

eliminating the need for additional

guarding or outside mounting.

7-segment display

If an error is ever detected by the light

curtain, the 7-segment display provides

a code that indicates the cause, which

greatly reduces the time required to take

corrective action.

One-line system

Reduce connections to as few as 5 wires

by using this system that eliminates

transmitter wiring completely.

Simple

Reduce installation time with simple wiring and easy-to-use
mounting brackets.

The introduction of the one-line system and optical synchronisation simplies

connections to as few as 5 wires.

1. No assembly required

Traditionally, mounting brackets have required assembly

before installation. However, the GL-R Series brackets

come pre-assembled, so installation is as simple as

sliding them into the mounting track and securing them

to the machine.

2. Insert the bracket into the mounting track

The GL-R Series is designed to simplify mounting by

inserting the brackets into the mounting track and

locking them in place.

3. Mount directly to standard extruded aluminium framework

The GL-R Series mounting brackets have been designed

to attach directly to standard extruded aluminium

framework without the need for any additional hardware.

GL-T11R Type4 Quick Disconnect Safety Relay

The GL-T11R combines all of the features necessary to build a Category 4 compatible safety circuit in a single unit.

This makes it possible to dramatically reduce the amount of time and labour required by complex circuit design processes.

It also boasts quick disconnects that simplify the wiring process involved in connecting the light curtain to the relay.

The GL-T11R reduces the need for specialised knowledge about safety circuits.

Quick Disconnect

The safety light curtain is connected

via a quick disconnect, eliminating the

danger of wiring mistakes and reducing

the amount of time and labour required

for wiring.

*1 If the interruption is present in the detection zone for less than 80 ms, the response time (OFF to ON) will
be 80 ms or more to ensure that the OSSD maintains the OFF state for more than 80 ms.

*2 “All blocked” means the situation where the GL-R operates in optical synchronisation system and the
transmitter and receiver is not synchronised (top and bottom beam axes are both blocked). In this situation,
the response time is longer because the GL-R synchronises the transmitter and receiver rst and then
determines the clear or blocked.

Point

• When the GL-R units are connected in series, the response time is

calculated according to the following steps;

1. Sum up the response time of all unit.

2

2. Subtract the following time from the result of previous step.

*

ON to OFF

One sub unit : 2 ms

Two sub unit : 4.2 ms

(When Optical synchronisation system and Channel A or B)

One sub unit : 2.7 ms

Two sub unit : 5.7 ms

OFF to ON

One sub unit : 42 ms

Two sub unit : 84 ms

When connecting the GL-R32H (32 beam axes), GL-R24H (24 beam axes), and
GLR12L (12 beam axes) in series for one-line system, the response time of each
unit is 7.9 ms, 7.0 ms, and 6.6 ms respectively, and the response time (ON to OFF)
is 7.9 ms + 7.0 ms + 6.6 ms - 4.2 ms = 17.3 ms.
The response time (OFF to ON) is 50.6 ms + 49.3 ms + 48.7 ms - 84 ms = 64.6 ms.

• 2.0 m/s is the maximum object detection speed of the GL-R series.

INTERLOCK FUNCTION

Interlock is a function that prevents the OSSD from automatically going to the
ON state from an OFF state. You can prevent the unintended start-up and/or the
unintended restart of the machine if an interlock is applied to the GL-R.

OSSD

The OSSD is a safety-related control output. It connects to an external device (load),
such as an FSD or MPCE. The GL-R generates self-diagnosis signals on its internal
control circuit to perform diagnostics on the output circuit (OSSD). These signals
periodically force the OSSD into a temporary OFF state when no interruption exists
in the detection zone.

EXTERNAL DEVICE BREAKDOWN DETECTION (EDM FUNCTION)

EDM (External Device Monitoring) is a function of the GL-R that monitors the state
of the control devices which are externally connected to the GL-R. The GL-R can
detect a fault, such as welded contacts on external devices, as long as the EDM
function is activated. This function is available only when connecting the 11-core
cable to the receiver.

WIR ING

• Each model is connected to one cable. Therefore, at least two cables are needed as a system, one for the transmitter and another for the

receiver.

Cable length

1. Optical synchronisation system, wire synchronisation system

The sum of the length for the unit connection cable and extension cable must be 30 m or
less. This limitation applies separately to the entire transmitter cable setup and the entire
receiver cable setup.

2. One-line system

The sum of the length for all of the unit connection cables, extension cables and series
cables

• All cables can be used for both the transmitter and receiver.

• The combination of the wiring system and cable determines the functions that can be used. Different types of cables can be used for the

transmitter and receiver.

• Be sure to match the numbers of conductors (core wires) when using the unit connection cable for extension use and the extension cable.

Reference

• When the synchronisation wire 1 or 2 is not connected, the GL-R operates in optical

synchronisation system.

• When optical synchronisation system or one-line system is applied, the input and output

functions on the transmitter are not available.

• The functions assigned to the input and output may differ according to the conguration

when setting through the conguration software.

• “Wiring systems” (page 24)

• Cables must be within the lengths specied. Failure to follow this

specication may cause improper operation of safety functions, and

• The series connection cable cannot be cut or extended. If the cable

is cut or extended, safety features may not operate properly. Do not
allow this to happen as it is extremely dangerous.

*2 If it is not necessary to perform error detection for K3 and K4 (when EDM

input is not used), use the shorting bar between No. 8 and No.9.

*3 In the auto reset mode, use the shorting bar between No. 10 and No.11.

To release the error condition of a GL-R through the reset input, connect a

N.C. switch.

Points

• Depending on the settings of the “Safety Device

switched to a different function. When the settings are
changed, check the wiring referring to the internal circuit
diagram in the previous section.

• The total electric current supplied from each 24 V
