SIGUARD 3RG784/3SF784Light Curtains, Light Grids and Evaluation Units

safetyINTEGRATED

Everywhere where people are working on or at machines running at

high speed with high associated forces, the highest degree of safety must be

guaranteed and that from all sides. Whether on edging presses or welding

robots, on punches, die-cast or injection moulding machines: SIGUARD

3RG784/3SF784 light curtains provide perfect protection with their optical

sensor blocking functions. They generate a two-dimensional protective field of

infrared light beams. If a person or an object enters this protective field, the

machine goes into a safe condition – the potential hazard is neutralized.

SIGUARD light curtains distinguish themselves due to their high noise immunity:

They have an extremely high degree of availability. These functions are imple-

mented using integrated circuits that have been specifically designed for the

purpose (ASICs) and an intelligent evaluation technique that has been patented.

General functions

Increases the noise immunity against powerful

external light sources (multi-scan)

If noise and disturbances are expected due to powerful

external light sources in rugged ambient conditions –

for instance as a result of stroboscopic lamps or welding

robots – if a beam is interrupted, it is often more practi-

cal to first wait until the interruption continues before

the outputs are shut down. This increases the degree of

availability of the plant/system whereby the response

time is increased and therefore the safety clearance.

Transmission channels

In order to be able to differentiate between the trans-

mitted infrared light and ambient light and to avoid the

infrared light from being influenced by e.g. warning

lights of passing forklift trucks or sparks from welding

equipment, the infrared light is transmitted in pulse

packages. The light curtains, light grids and transceivers

are equipped with two transmission channels.

Start/restart inhibit

The start/restart inhibit function can be activated in

order to prevent that the plant or system immediately

resumes operation after the protective field has been

interrupted and then becomes free again. When secur-

ing access to machines etc., it is absolutely mandatory

that the start/restart inhibit function is used. The rea-

son for this is that only the access to the hazardous

zone is monitored, but not the area between the pro-

tective field and the potentially hazardous motion.

Contactor monitoring

The contactor monitoring is used to monitor the con-

tactors, relays or valves connected downstream from

the light curtain. In this case, switching elements with

positively driven checkback signal contacts are required.

Area with reduced resolution

If objects are permanently in the area of the light

curtain, then these can be blanked using blanking

functions. This guarantees disturbance-free operation.

In this case, a differentiation is made between objects

at a fixed location, that are permanently in the

protective field, and moving objects that from time to

time can exit the protective field zone.

Fixed blanking

The “fixed blanking” function can be used if stationary

objects are permanently located within the protective

field of the light curtain. The light curtain permanently

monitors the blanked object: The light curtain moni-

tors whether the object is precisely located at that

position that was taught-in.

Floating blanking

The floating blanking function can be used if moving

objects are permanently located within the light cur-

tain area. The object that is blanked in a floating fash-

ion is permanently monitored: The light curtain moni-

tors whether the object is permanently located in the

light curtain area.

Reduced resolution

The reduced resolution function can be used if moving

objects are not permanently located within the protec-

tive field of the light curtain. Contrary to floating

blanking, the object is not permanently monitored.

When the “reduced resolution” function is used, then

the effective resolution of the light curtain changes.

The safety clearance must be re-calculated with the

effective resolution.

Muting functions

When vertically arranged, light curtains, light grids and

transceivers are often used to secure access to poten-

tially hazardous areas. The protective effect can be

muted by using additional sensor signals. For instance,

this function can be used to transport materials into or

out of the hazardous area. The protective field is tem-

porarily muted and is re-enabled after the materials

have passed.

Muting restart

If, for example, the power supply fails while the mate-

rials being transported are passing the muting sensors,

the valid muting sequence is interrupted. If the power

supply voltage returns, the muting operation is not au-

tomatically continued as the expected muting sequence

is not provided. In order to remove the materials being

transported from the area of the muting sensors, an

integrated move-away mode can be provided using

the start button.

4-sensor sequential muting

If the material to be transported into the

hazardous area always has the same di-

mensions and space is not restricted, then

sequential muting is preferably used. For

sequential muting, four muting sensors

are connected that must be activated in a

specified sequence in order to initiate the

muting operation.

2-sensor parallel muting

Parallel muting is preferably used in those

plants and systems where the dimensions

of the materials being transported are not

constant or where space is restricted. This

can be used with two muting sensors whose

beams then cross behind the protective

field in the hazardous zone.

3-sensor direction muting

The 3-sensor direction muting has a similar configura-

tion to the 2-sensor parallel muting. The material can

only be transported through the light curtain in one

direction. In order to initiate the muting function, ini-

tially muting sensor M1 must be activated and then

the two muting sensors M2 and M3. If the paths of

muting sensors M2 and M3 are interrupted, it is no

longer necessary to activate sensor M1.

4-sensor parallel muting

If the material being transported is too small to be

simultaneously detected by 4 sequentially located

sensors, and if space for the application is restricted,

in order to implement the light barrier crossover of

the 2-sensor parallel muting function, the 4-sensor

parallel muting function can be used, e.g. using

sensors. As far as the function is concerned, the

4-sensor parallel muting corresponds to the 2-sensor

parallel muting function – however the activation

signal is retrieved from two pairs of sensors.

15

Fast and productive operation

Machine motion is initiated by the light curtain. The

optional cycle control function should be selected if

it is necessary to intervene once or twice in the protec-

tive field of the light curtain (e.g. to insert or remove

workpieces).

3RG7841 light curtains are devices belong-

ing to Category 2. Together with the

3RG7825 evaluation unit, they can be used

for start/restart inhibit or, together with the

3RG7847 evaluation units, for additional

functions such as muting and cycle control.

In this case, the evaluation unit supplies the

necessary test signal.

21

22

The complete safety system comprises the following:

• One evaluation unit and the associated light barriers

for Category 2, and

• Two light barriers for Category 4

3RG7823 light barriers for Category 2

• Range 0 to 150 m

• Degree of protection IP65

• Connection via M12 connector

• Integrated heating for the optical system

3RG7824 light barriers, Category 4

• Range 0 to 60 m

• Degree of protection IP65

• Frequency-modulated infrared light

• Integrated dirt accumulation monitoring using an LED

• Integrated heating for the optical system

• High mechanical and chemical resistance thanks

to the glass optical system

3RG7825 evaluation units for Category 2

• Start and restart inhibit

• Contactor monitoring

• Electrically isolated safety outputs

• Separate signaling outputs as pnp transistor outputs

• Permanent cyclic testing

• Operating function is not interrupted when testing

• Series circuit of up to 6 pairs of light barriers

Muting function with light barriers

A muting function can be implemented together

with the 3RG7847 evaluation units.

The 3RG782 series of light barriers can be used for

applications involving Categories 2 or 4. When

combined with the 3RG7825 evaluation unit, the

3RG7823 light barriers, Category 2, allow functions

such as start/restart inhibit and contactor monitoring

to be implemented.

We recommend the 3RG7847 evaluation units for

muting functions and for combining with the

3RG7824 light barriers, Category 4.
