of the device” on page 10. It must be used only by qualified personnel on the machine

where it has been installed and initialised by specialist personnel in accordance with these

operating instructions. It is only permitted to be used on machines on which the dangerous

state can be stopped immediately by the S300 and/or it is possible to prevent the

machine being placed in operation.

If the device is used for any other purposes or modified in any way — also during mounting

and installation — any warranty claim against SICK AG shall become void.

2.2 Specialist personnel

The S300 safety laser scanner must be installed, connected, commissioned and serviced

only by specialist personnel. Specialist personnel are defined as persons who

 due to their specialist training and experience have adequate knowledge of the power-

driven equipment to be checked

and

 who have been instructed by the responsible machine operator in the operation of the

machine and the current valid safety guidelines

and

 are sufficiently familiar with the applicable official health and safety regulations,

directives and generally recognized engineering practice (e.g. DIN standards, VDE

stipulations, engineering regulations from other EC member states) that they can assess

the work safety aspects of the power-driven equipment

and

 who have access to these operating instructions and who have read them.

As a rule these are specialist personnel from the ESPE manufacturer or also those persons

who have been appropriately trained at the ESPE manufacturer, are primarily involved in

checking ESPE and are allocated the task by the organisation operating the ESPE.

2.3 Applications of the device

The S300 safety laser scanner is used to protect persons and plant. It is intended to be

used to monitor hazardous areas indoors.

It is not allowed to use the S300 outdoors.

The S300 cannot provide protection from parts thrown out of the machine or radiation

emitted.

The S300 complies with the requirements in the standard on the radiated emissions as

defined for class A (industrial application); the S300 is therefore only suitable for use in an

industrial environment.

3.3 Function

T

he S300 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.



After integration in the control it must be possible to transfer the dangerous machine,

system or vehicle state to a safe state using the OSSDs on the S300 at any time, i.e.

before a person has reached the hazardous point or hazardous area.

 The S300 must be mounted and configured such that it detects objects as they enter

the hazardous area (see chapter 4 “Mounting” on page 37 and chapter 8

“Commissioning” on page 74).

3.3.1 Principles of operation

The S300 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.

The S300 works on the principle of time of flight measurement. It sends out very short

pulses of light (S). At the same time an “electronic stopwatch” is started. When the light is

incident on an object, it is reflected and received by the safety laser scanner (E). From the

time between sending and reception (t) the S300 calculates the distance to the object.

In the S300 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 S300 sends a pulse of light with an angular resolution of 0.5°. In this way resolutions

from 30 to 70 mm can be achieved independent of the length of the protective field !

Due to its active scanning principle, the S300 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.

3.3.2 Field set comprising of protective field and warning field

The S300 protects the hazardous area on a machine or a vehicle using the protective

field . 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.

You can define the warning field  such that the safety laser scanner detects an object

before the actual hazardous area and e.g. triggers a warning signal.

The maximum distance at which the safety laser scanner can detect an object is defined

by the distance measuring range .

Protective field and warning field form a pair, the so-called field set. Depending on the

variant used (see section “S300 variants” on page 16), you can define up to four field sets

and save these in the safety laser scanner. In this way you can switch the S300 Advanced

and S300 Professional safety laser scanners to a different field set in case of a change in

the monitoring situation (see section 3.3.3 “Monitoring cases” on page 20).

You can configure and transfer these field sets to the with the aid of the CDS S300. If the

hazardous area to be monitored changes, then you can re-configure the S300 in software

without additional mounting effort.

3.3.3 Monitoring cases

Depending on the variant used (see section “S300 variants” on page 16) up to four

monitoring cases can be defined and selected during operation using static or dynamic

control inputs. In this way, for instance, it is possible to monitor vehicles as a function of

the velocity.

With the aid of a monitoring case you can define for a field set …

 the field conditions (control signals) for switching to the related field set.

 which multiple sampling is used for the field set.
