3 Product description

3.1 Application description

The Safeguard Detector Core application package is used on machines with material

ansportation systems, such as a carton magazine on a packaging machine, to prevent

the risk of people getting injured by the empty material transportation system in the

event of interrupting the machine.

The transportation opening to a packaging machine is monitored by at least two sen‐

sors. If there is carton in the magazine, an interruption is not possible because the

material acts like a physical guard. The same principle applies in other plants for other

objects acting as a physical guard (e.g., transport containers).

Figure 1: Material in the detection zone: carton magazine sufficiently filled

If t

he magazine is not sufficiently filled or is empty, a person can interrupt the machine.

This represents a dangerous state. The task of the Safeguard Detector application

package is to prevent this case by reacting in a safety-related manner and switching off

the system.

Figure 2: No material or too little material in the detection zone: carton magazine not sufficiently

illed

Limits of the system

The f

igure below shows the limits of the Safeguard Detector application package. The

system considered ends at the outputs of the SICK safety controller. Furthermore, the

user is solely responsible for the safe design of the entire system.

Subject to change without notice

Figure 3: Block diagram of the safety chain and limits of the system

The Saf

eguard Detector application package represents the part of the safety chain

that combines the sensors and safety controller. This combination carries out a sub-

safety function. The safety chain can be expanded with additional logic elements

(e.g., a higher-level control).

3.2 Safety function

The sensors are evaluated by means of a SICK safety controller. If the system detects

hat the machine opening is not sufficiently covered by suitable objects, meaning that

an interruption or access to the hazardous point is not reliably prevented, the accord‐

ingly configured outputs of the safety controller are switched off.

The objects to be detected act as physical guards. They must be selected such that they

carry out their separating function sufficiently and reliably.

The separating function must also be effective during the lapsing of the safety function

response time (e.g., while hazardous system movements are stopping after the safety

function has been triggered).

DANGER

The t

echnical process parameters must be set to ensure that so many objects are in

the infeed so that they still function as physical guards after the system is switched off

by the application package.

This means that the application package must switch off the system before the neces‐

sary number of objects in the infeed for maintaining protection is undercut. Otherwise,

this would mean that the user is at risk.

3.3 Safe state

In the safe state, the accordingly configured safe outputs are in the off state. The

machine is and remains switched off. The safe state is initiated in the following cases:

•

No object is detected in the protective field in the time in which the sensors are

being evaluated; the output of at least one sensor is therefore in the off state.

•

The connection between at least one sensor and the SICK safety controller has

been interrupted.

•

The power supply of at least one sensor and/or the SICK safety controller has

been interrupted.

•

An error is diagnosed in at least one sensor.

•

The saf

ety controller receives implausible output signals from the two sensors

beyond the duration of the configured maximum discrepancy time.

•

An internal error has occurred in the SICK safety controller or in one of its compo‐

nents.

3.4 System components

The Safeguard Detector application package consists of the following components:

•

A sensor pac

kage consisting of two identical MultiPulse photoelectric proximity

sensors (2x2 or 2x10 Hz).

•

A SICK safety controller

For product packages and accessories that can be ordered, see "Ordering information",

page 33.see "Ordering information", page 33.

Sensor technology

The sensor par

t of the system consists of two sensors, both of which are able to trigger

the safety function. As a result of this dual-channel structure (“1 out of 2”), the system

and sensor are single-failure-proof.

Two sensor variants with various pulse rates and response times are available.

NOTICE

•

The per

missible sensor variants for the Safeguard Detector application package

cannot be configured. The customer is responsible for selecting the correct variant

and testing it during the validation.

•

Which sensor variant is suitable depends on the logic execution time of the safety

controller, among other things, see "General sensor data", page 31.see "General

sensor data", page 31.

•

Only sensor variants listed here may be used.

•

Only sensor pairs with the same pulse rate may be used. A 2 Hz sensor may not be

combined with a 10 Hz sensor.

The detection zone of the sensors is 30 to 100 mm:

•

4 Project planning

This chapter includes important information about the proper integration of the Safe‐

guar

d Detector application package for planners, developers, and designers.

4.1 Security

DANGER

Dang

erous state of the machine

Make sure that the dangerous state of the machine is and remains switched off

during mounting, electrical installation, and commissioning.

Make sure that the safety controller outputs do not affect the machine during

mounting, electrical installation, and commissioning.

DANGER

Hazar

d due to lack of effectiveness of the protective device

If insufficiently mounted or subjected to excessive vibrations, the sensors may become

detached or damaged.

It is possible for people to interrupt the hazardous area when the machine is running.

Where necessary, take suitable vibration reduction measures.

DANGER

The pat

h of the beam between the sensor and the object being detected must always

be kept free and must not be disrupted or manipulated by any other objects.

4.2 Prerequisites

Structural prerequisites

The sy

stem only detects the surfaces of objects and not intervention by a person into

the hazardous area of the machine. For this reason, ensure that the detected object

covers the hazardous area in a manner that sufficiently prevents access or interruption.

The distance between the object (e.g., carton blanks) and the machine must not be so

big that an interruption by a person is possible or else there may still be a hazard

despite an object having been detected (which is the movable physical guard).

If the object moves to the side in the magazine, an interruption opening may be cre‐

ated, which, in some circumstances, may not be detected by the sensors. Correspond‐

ing countermeasures must be taken by the machine user.

Optical properties of objects

DANGER

ransparent objects (film packing , bottles, etc.) may cause availability problems as a

result of their direction-changing effect on light and may lead to safety-relevant incor‐

rect switching. For this reason, such objects must be kept out of the sensing range of

the sensors.

The objects to be detected must have the following properties:

•

The r

emission of the objects must be between 6 % and 90 % of a diffusely scatter‐

ing nature. This corresponds to black to white carton surfaces.

•

Very dark and retroreflective or shiny objects may cause availability problems.

4.3 Setup location

Positioning the sensors

It mus

t be ensured that enough objects are in the magazine to effectively prevent inter‐

vention.

The sensors must be positioned so that they trigger the safety function before the

respective quantity of objects is undercut.

4.4 Response time

When configuring the machine, the response time of the entire system must be taken

int

o consideration. If interruption is possible when a magazine is empty, the stopping

time of the system must be calculated and the distances to the hazardous points nec‐

essary based on this must be complied with.

When calculating the total response time, the following possible influences must be

taken into consideration:

•

Sensor response time

•

Safety controller response time

•

Signal transit time between OSSD and actuator

•

Actuator stopping/run-down time

4.5 Integrating into the electrical control

DANGER

If there is a foreign object in the sensor detection zone, this is not detected as an error

during normal operation. The same applies if the sensor becomes detached from its

position due to a mounting error and therefore constantly detects a foreign object, such

as the floor. An error of this kind is discovered by a plausibility check.

The logic program must check the plausibility of the sensor signals by evaluating

the discrepancy time, for examplesee "Application logic", page 22.

Restart interlock and reset

The sensor

s cannot differentiate between an object in the magazine and body parts. If

it is possible that a person could interrupt the hazardous area and therefore cancel out

the safe state, a restart interlock is required.

In this, the result of the series-connected frequency monitoringand the tolerant dual-channel

evaluation function blocks is sufficient as the condition for a restart.

The user is responsible for deciding whether or not a restart interlock is required.

Cross-circuit detection

The dual-c

hannel integration of the sensors requires a detection or the prevention of

cross-circuits between the cables of the sensors to the SICK safety controller. This two

sensors must have separate power supplies and cabling in different rooms.

To protect the sensors from overvoltage, the sensors must be supplied with power via

the Flexi Soft safety controller, see "Wiring notes", page 20.

A corresponding configuration must be carried out in the SICK safety controller logic

program.

4.6 Testing plan

Various tests are required for the Safeguard Detector to function correctly:

PROJECT PLANNING 4

8019465/2016-03-10 | SICK O P E R A T I N G I N S T R U C T I O N S | Safeguard Detector

Subject to change without notice

•

A t

horough check must be carried out during commissioning and following modifi‐

cations, see "Validation", page 26.

•

In many cases, depending on the application conditions, the risk assessment

determines that regular checks are required, see "Recommendations for regular

checks", page 16.see "Recommendations for regular checks", page 16.

The manufacturer and user must define the type and frequency of the thorough checks

on the basis of the application conditions and the risk assessment.

Determination of the thorough checks must be documented in a traceable manner.

4.6.1 Recommendations for regular checks

In many cases, depending on the application conditions, the risk assessment deter‐

mines t

hat regular checks are required.

The regular thorough checks serve to investigate the effectiveness of the protective

device and discover defects because of modifications or external influences (such as

damage or tampering).

The definition of the necessary intervals and reasons is dependent on vibrations on the

machine, among other things, which can be transferred onto the sensors.

Possible regular thorough check intervals or reasons:

•

When the batch is changed

•

When the system has been switched off because no object has been detected

(e.g., when the carton magazine is empty)

•

During repair or maintenance breaks

In many cases, it makes sense to carry out the following checks regularly:

•

Thorough visual check of the machine and the protective device, page 16

•

Thorough check of the principal function of the protective device, page 17

•

Inspection of whether the sensors are still in the correct position

•

Check of the relevant validation points, see "Validation", page 26

•

Thorough check of the relevant points on the checklist, see "Checklist for initial

commissioning and commissioning", page 36

If a thorough check discovers a fault, the machine must be shut down immediately. In

this case, the mounting and electrical installation of application package must be

checked by appropriately qualified safety personnel.

4.6.2 Carrying out thorough checks

Thorough visual check of the machine and the protective device

SIC

K recommends the following procedure:

Check whether the machine or the protective device has been modified or manipu‐

lated so that the effectiveness of the protective device may be impaired.

Check the following points in particular.

Has the machine been retrofitted?

Have machine parts been removed?

Have modifications been made to the surroundings of the machine?

Are there any defective cables or open cable ends?

Has the protective device been completely or partially dismantled?

Is the protective device damaged?

Is the protective device severely contaminated?

Are the front screens of the sensors contaminated, scratched, or destructed?

Has the alignment of the sensors been changed?

Are there any objects (e.g., cables, reflective surfaces) in the detection zone?

If one of the points applies, the machine must be shut down immediately. In this case,

he machine and the protective device must be checked by appropriately qualified

safety personnel.

Thorough check of the principal function of the protective device

SICK recommends the following procedure:

Test the function of the protective device by triggering the protective function and

observing the reaction of the safe outputs using the reaction of the machine, for

example.

Move an object into the beam of light of the first sensor so that the beam of

light hits the object at a distance of < 30 mm from the sensor (minimum

sensing range = 30 ). The OSSD switching outputs of the Flexi Soft safety

controller must switch to the safe status and stop the dangerous movement.

Remove the material from the maximum sensing range of the sensor

(> 100 mm). The OSSD switching outputs of the Flexi Soft safety controller

must switch to the safe status and stop the dangerous movement.

Repeat the thorough checks with the second sensor.

If a thorough check discovers a fault, the machine must be shut down immediately. In

this case, the mounting and electrical installation of application package must be

checked by appropriately qualified safety personnel.

5 Mounting

5.1 Placing the sensors

Correct distance between the sensors and the material

The sensor

s must be mounted so that the limits of the detection zone – i.e., the values

for the minimum and maximum distance to the object being detected – are complied

with. The minimum distance is 30 mm; the maximum permissible distance is 100 mm.

Sufficient distance between the light points of the sensors

The sensors must detect the material at two different points. Otherwise, reliable detec‐

tion is not possible.

Furthermore, the light points of the two sensors must be far enough from one another

to eliminate the risk of mutual interference between the sensors.

Positioning the sensors in relation to one another

The sensor

s should be positioned at a slight angle to the object being detected (see

figure 5). Otherwise, the beam of light could pass through a gap between the objects

and not be reflected inside the detection zone despite material being present. This can

lead to an unintended shut-down.

Furthermore, the sensors should be mounted at different heights. The paths of the

beams of the sensors must not run parallel to one another. These measures increase

availability because this practically eliminates the risk of mutual interference between

the sensors.

Interference of the sensors

DANGER

The f

ollowing types of interference must be ruled out because they could impair the

safety function.

•

Mirrored, reflective, shiny, or transparent surfaces and holograms are not permit‐

ted in the detection zone.

•

No light source and no reflective or retroreflective objects may be located in the

extension of the beam path outside of the detection zone (i.e. behind the object to

be detected).

•

Direct sunlight or very bright sunlight must be prevented from interrupting the

detection zone of the sensors.

•

The sensors must not be illuminated with low-frequency ambient light in the area

around 100 Hz or with high-frequency ambient light in the kHz range.

5.2 Mounting the sensors

The sensor

s are mounted using a suitable mounting bracket, see "Ordering infor‐

mation for accessories", page 34.

Use self-locking nuts.

Do not screw the fixing screws tightly yet because the sensor needs to be real‐

igned after electrical installation, see "Positioning and aligning the sensors",

page 22.see "Positioning and aligning the sensors", page 22.

The maximum permissible tightening torque of the fixing screws is 0.8 Nm.
