Function

The SafeZone Mini safety laser scanner operates correctly as a protective device only if the following conditions are met:

•The control of the machine, system or vehicle must be electrical.

•It must be possible to transfer the dangerous machine, system or vehicle state to a safe state using the OSSDs on the SafeZone Mini at any time, i.e. before a person has reached the hazardous point or hazardous area.

Or:

It must be possible to transfer the dangerous state of the machine, the system, or the vehicle to a safe state at any time using the OSSDs on a safety controller connected to the SafeZone Mini.

•The SafeZone Mini must be mounted and configured such that it detects objects as they enter the hazardous area (see Chapter 5, “Mounting” on page 35 and Chapter 9, “Commissioning” on page 47).

•The safety laser scanner’s optical path must always remain clear and is not allowed to be covered by transparent objects such as protective windows, Plexiglas, lenses etc. The safety laser scanner’s protective function can only be ensured if the contamination measurement function is not bypassed by such measures.

Principle of operation

The SafeZone Mini is an optical sensor that scans its surroundings in two dimensions using infrared laser beams. It is used to monitor hazardous areas on machines or vehicles.

Chapter 3 Product description

Fig. 2: Principle of operation, rotation of the SafeZone Mini

The SafeZone Mini works on the principle of time-of-flight measurement. It sends out very short pulses of infrared light (send pulses). At the same time an “electronic stopwatch” is started. When the light hits an object, it is reflected and received by the safety laser scanner (receive pulses). From the time between sending and reception ( t) the SafeZone Mini calculates the distance to the object.

180°

-45°

90°

Fig. 3: Field set with one protective field and two warning fields

In the SafeZone Mini there is also a mirror rotating at constant speed that deflects the light pulses such that they cover an arc of 270°. In this way an object can be detected in the protective field within 270°. The first beam of a scan starts at –45° relative to the back of the safety laser scanner.

The SafeZone Mini sends a pulse of light with an angular resolution of 0.5° . As a result resolutions between 30 mm (1.18 in.) and 70 mm (2.76 in.) can be achieved .

Due to its active scanning principle, the SafeZone Mini does not require receivers or reflectors. This has the following advantages:

•Your installation effort is lower.

•You can easily adapt the monitored area to the hazardous area on a machine.

•In comparison with contact sensors, electro-sensitive scanning is nearly wear-free.

Field set comprising protective field and warning field(s)

Protective fields and warning fields form the so-called field set. You can configure these field sets with the aid of the SCD software. The fields can be configured as circular, rectangular or of arbitrary shape. If the area to be monitored changes, then you can re-configure the SafeZone Mini in software without additional mounting effort.

You can configure field sets comprising one protective field and one or two warning fields.

The SafeZone Mini secures the hazardous area on a machine or vehicle. As soon as the safety laser scanner detects an object in the protective field, it switches the OSSDs to the OFF state and thus initiates the shutdown of the machine or stop of the vehicle.

Protective field

Warning field

Warning field 2

You can define the warning fields such that the safety laser scanner detects an object before the actual hazardous area.

Warning field 1 can be used in particular for vehicle protection to detect an object even before the actual hazardous area and to slowly retard the movement of the vehicle or bring it to a standstill. In this way the wear on the brakes on an AGV can be reduced. Warning field 2 can also be used to trigger a warning signal.

You can enter your name in the field Name of the user. You can enter a name with a maximum of 22 characters. This is then added to the configuration protocol and in the diagnostics report.

Display direction of the seven­segment display

The depiction of numbers on the seven­segment display can be rotated by 180° with the aid of the SCD software. This is useful, for example, when the SafeZone Mini must be rotated by 180° owing to the specific assembly.

If you rotate the numbers of the seven­segment display, the point in the seven­segment display goes out.

How to determine the display direction of the seven­segment display:

Under seven­segment display, activate the Rotated by 180° option. After the configuration draft has been transferred to the SafeZone Mini, the numbers of the seven­segment display are rotated by 180°.

Resolution

The maximum protective field range depends on the configured resolution. The following table shows the related maximum protective field range at the resolutions that can be set:

Configured resolution [mm (in.)]	Maximum protective field range [m (ft)]
	2 m		3 m
30 (1.2) – (hand detection)	1.25 (4.1)		1.25 (4.1)
40 (1.6) – (hand detection)	1.60 (5.2)		1.60 (5.2)

150 (5.9) (whole body detection)		3.00	(9.84)

Note The warning field can be configured to up to 8 m (26.25 ft) for all resolutions. The detection capability within the warning field is dependent on the remission of the objects to be detected (see Chapter 12, “Technical Specifications” on page 55).

Basic response time

The basic response time of the SafeZone Mini is 80 ms.

Note You may need to add supplements to the basic response time due to multiple sampling (see Chapter 12, “OSSD response times” on page 55).

Maximum protective field range

Depending on the configured resolution used (see Chapter 4, “Resolution” on page 16), the maximum protective field range of the safety laser scanner is shown in the SCD software.

Note The maximum protective field range of the SafeZone Mini must be sufficient to cover the calculated protective field size including the necessary supplements (see Chapter 5, “Protective field size” on page 25).

In mobile applications a resolution of only 70 mm (2.8 in.) is required for leg detection.Radial distance to the safety scanner.

Chapter 4 Configurable functions

Universal I/O connections of the SafeZone Mini

ATTENTION

You are not allowed to use the universal I/O connections for safety-relevant functions!

You are only allowed to use the universal I/O connections for signaling. You must never use the signals for controlling the application or for safety-relevant functions.

The SafeZone Mini has two universal I/O connections (see Chapter 6, “Round plug connector SafeZone Mini” on page 40). You can configure these two connections for the following functions:

• Inactive (factory default setting)

As inputs (it is only possible to select one function per universal I/O connection):

•Stand-by

•External device monitoring (EDM) (see page 18)

•Resetting the restart interlock (see page 18)

As outputs (it is possible to select several functions per universal I/O connection, these functions are linked together using an OR operator):

•Device error

•Contamination error

•Contamination warning

•Second warning field

•Reset required

Note Other functions that can be configured are dependent on the configuration of the universal I/O connections. For example, you can only realize a restart interlock if you configure one of the universal I/Os as an input for resetting the restart interlock.

The universal I/O connections are configured in the SCD software in the Universal I/O area. Fig. 7 shows a configuration example.

Fig. 7: Configuration example universal I/O connections of the SafeZone Mini

Stand-by

If, in mobile applications, vehicles are not moved for a time, the OSSDs can be switched to the OFF state and the laser on the SafeZone Mini can be switched off. In this way the power consumption of the device is reduced.

Recommendation Use this function if, e.g. you use several vehicles and do not move them for a time.

The SafeZone Mini remains in the stand-by mode as long as the related input information is present.

OSSDs

Internal OSSDs of the SafeZone Mini

Table 6: Behavior of the SafeZone Mini on a contactor malfunction

If there is an object in the protective field, the internal OSSDs on the SafeZone Mini always switch. This can not be configured differently in the SCD software.

External device monitoring (EDM) SafeZone Mini

The EDM checks if the contactors actually de-energize when the protective device is tripped. If you activate external device monitoring, then the SafeZone Mini checks the contactors after each interruption of the protective field and prior to the machine restart. The EDM can so identify if one of the contactors has welded, for instance. In this case the external device monitoring places the system in a safe operational state and the OSSDs are not switched back to the ON state.

The table shows how the SafeZone Mini reacts if the external device monitoring detects a contactor malfunction:

Without internal restart interlock	•	The system locks completely (lock-out).
or	•	The error message 8 appears in the seven­segment display.
with restart delay
With restart interlock	•	The SafeZone Mini switches its OSSDs to the OFF state.
	•	The LED	is illuminated.
	•	The error message		.	e appears in the seven­segment display.

You can configure the external device monitoring in the SCD software.

Note

Restart of the SafeZone

Mini Standard

ATTENTION

You will find examples on the connection of the external device monitoring in Chapter 7, “Connection diagrams” on page 43.

You can configure the restart behavior of the SafeZone Mini as follows:

•Without restart interlock

•With restart delay

•With restart interlock

You can configure the type of restart in the SCD software.

It is imperative that you configure the SafeZone Mini or the application with restart interlock if the protective field can be left to approach the hazardous point or if a person cannot be detected by the SafeZone Mini at every point in the hazardous area!

During the assessment, pay attention to whether the protective field can be left in the direction of the hazardous point, to areas that are unprotected due to the mounting and the unprotected near range of the SafeZone Mini (see Chapter 5, “Methods of preventing unprotected areas” on page 33).

Configuration of the SafeZone Mini without restart interlock

After the OSSDs on the SafeZone Mini have been switched to the OFF state due to an object in the protective field, the OSSDs are re-enabled again immediately when there is no longer an object in the active protective field.

This configuration is only allowed …

• If an external restart interlock is realized on the machine controller

or

•If the protective field cannot be left in the direction of the hazardous point and if people can be detected by the SafeZone Mini at every point in the hazardous area!

Restart delay for mobile applications

In mobile applications you can configure a restart delay from 2 to 60 seconds on the SafeZone Mini. The OSSDs on the SafeZone Mini change to the ON state if there is no object in the protective field for the duration given.

This configuration is only allowed if the protective field cannot be left in the direction of the hazardous point and if a person can be detected at every point in the hazardous area by the SafeZone Mini!

Configuration of the SafeZone Mini with restart interlock

Fig. 8: Schematic outline of the operation with restart interlock

Note

Do not confuse the restart interlock with the starting interlock on the machine. The starting interlock prevents the machine starting after switching on. The restart interlock prevents the machine starting again after an error or a protective field infringement.

The OSSDs on the SafeZone Mini change to the OFF state to initiate a machine or vehicle stop as soon as there is an object in the protective field . They do not change to the ON state , even if there is no longer an object in the protective field. The OSSDs only change to the ON state if the operator operates the control switch for restart or reset.

ATTENTION

Place the control switch for restart or reset outside the hazardous area in a place where it can clearly be seen from the hazardous area!

Place the control switch for restart or reset outside the hazardous area such that it cannot be operated by a person in the hazardous area. Ensure that the person who operates the control switch has a full view of the hazardous area.

Notes • You will find examples on the connection of the internal restart interlock in Chapter 7, “Connection diagrams” on page 43.

•If you do not use the internal restart interlock, then do not configure any of the universal I/Os as an input for resetting (see Chapter 4, “Universal I/O connections of the SafeZone Mini” on page 17).

Reset

Note The reset function is often also called “preparation for restart.” In these operating instructions the term reset is used.

If you want to activate the restart interlock on the SafeZone Mini (internal) and also a restart interlock on the machine (external), then each restart interlock has its own control switch.

After operating the control switch for the internal restart interlock (with protective field unoccupied) …

•The SafeZone Mini switches its OSSDs to the ON state.

•The LED on the SafeZone Mini illuminates green.

The external restart interlock prevents the machine from restarting. After resetting the SafeZone Mini the operator must press the control switch to restart the machine controller.

ATTENTION

Ensure that the correct sequence is followed!

The controller must be realized such that the machine only restarts if the SafeZone Mini is first reset and then the control switch for restarting the machine controller is operated.

Reset signals

If the SafeZone Mini safety laser scanner is operated using the “With restart interlock” function, then after a protective field infringement and the subsequent clearing of the protective field, it requests a reset signal from the control system (reset required).

ATTENTION

The reset signal must be safety-related (single failure proof)!

Chapter 4 Configurable functions

Field sets	Configuring the protective field and warning field
	With the aid of the SCD software you can configure the field set, which comprises a protective field and two warning
	fields . During this process you configure the shape and size of the protective and warning fields. You can realize any
	field shape required.

Fig. 9: Creating a field set in the SCD software

Note The area to be monitored is scanned radially by the SafeZone Mini. The SafeZone Mini cannot see through objects during this process. The area behind objects that are in the area to be monitored (pillars, grilles, etc.) can thus not be monitored.

Protective fields and warning field can cover up an angle of up to 270° and have different radial scanning ranges depending on the resolution configured (see Chapter 4, “Resolution” on page 16).

ATTENTION

Check the protective fields configured!

Prior to commissioning the machine or vehicle, check the configuration of the protective fields using the instructions in

Chapter 9, “Commissioning” on page 47 and using the “Checklist” on page 70.

Note If the protective field or the warning fields stretch as far as a wall or another object (pillar, neighboring machine, shelf), there should be a distance of 100 mm (3.94 in.) between the protective field or warning field and the object to prevent false triggering .

Fig. 10: Configuring protective field and warning field

ATTENTION

Secure unprotected areas!

If it is possible to access a narrow strip between the protective field and a wall or another object, you must protect this strip using additional measures (e.g. fence or floor protection).

Protective field or warning field suggested by the safety laser scanner

The SCD software can suggest the protective field or warning field in the field set editor. The safety laser scanner scans the visible surrounding contour several times. From the data obtained the SCD software suggests the contour and size of the field. The following figure shows an example for the reading of a protective field:

Fig. 11: Reading the protective field

In those places at which the surrounding contour is smaller than the maximum protective field range (e.g. at ), the protective field corresponds to the surrounding contour.

Note The measuring error tolerances for the SafeZone Mini are automatically subtracted from the protective field size. As a result the protective field is slightly smaller than the surface covered .

In those places where the surrounding contour is larger than the protective field range , the protective field corresponds to the possible scanning range.

ATTENTION

Check the protective field suggested by the SCD software

The protective field suggested by the SCD software is not a replacement for the calculation of the minimum distance. Calculate the minimum distance and check the effectiveness of the protective fields prior to commissioning the application!

Pay attention to the descriptions in Chapter 5, “Mounting” on page 24, the notes in Chapter 9, “Commissioning” on page 47 and the “Checklist” on page 70.

Using the contour as a reference

In addition to the protective field, the SafeZone Mini can also monitor a contour (e.g. the floor in vertical applications).

Fig. 12: Schematic diagram of contour as reference

For contour monitoring you define a contour segment . The contour segment comprises a positive and a negative tolerance band.

Rockwell Automation Publication 10000337275 Ver 01—October 2014

21

Chapter 4 Configurable functions

The OSSDs on the SafeZone Mini change to the OFF state or the SafeZone Mini Remote signals if …

•There is an object in the protective field.

•The monitored surrounding contour is no longer in the tolerance band (e.g. if the position of the SafeZone Mini is changed).

Notes • You can define any number of contour segments.

•The contour segments must not be narrower than the configured resolution.

•At the points where a contour has been configured as a reference you cannot define warning fields. If, for example, you use the floor as a reference for access protection, you cannot configure a warning field there. However, you can, e.g., configure a warning field to the left and right of the contour segment to control a warning signal on approach from the side.

•The contour as reference function and the warning field 2 function are mutually exclusive.

You define the contour as a reference in the SCD software field set editor.

Vertical operation

In vertical operation (for access protection and hazardous point protection) according to CLC/TS 61496­3 you must always configure the protective fields used with the contour as reference function.

Fig. 13: Contour as reference for vertical operationProtective field

Contours of the machine openingContour segment

Recommendation Use lateral, vertical boundaries of the opening (e.g. door frame) and the floor as reference. If in this case the position of the SafeZone Mini is changed in one or more planes, the distance to the reference changes and the SafeZone Mini switches its OSSDs to the OFF state.

Monitoring cases

The SafeZone Mini supports a configuration with monitoring cases.

ATTENTION

Ensure for each monitoring case that the minimum distance to the hazardous area is maintained!

See Chapter 5, “Mounting” on page 24.

You can configure the monitoring cases in the SCD software.

Each monitoring case includes …

•The input conditions, the so-called control signals, that control the activation of the monitoring case.

•A field set, comprising of protective field and warning field or fields.

•The multiple sampling for the field set.

Monitoring cases can be switched with the following input information:

• Static information
