Section 3 - APPLICATIONS

It is important that the type of safeguarding system is suitable for the application for which it is intended.
A documented process of risk assessment of the machinery or process will reveal the identity and nature
of the hazards together with other relevant information. The characteristics of the safeguarding system
should then be compared with the results of the risk assessment to determine whether the risk can be
reduced to an acceptable level. On some applications the combined use of more than one type of
safeguarding system may be necessary to achieve an acceptable level of risk.

The system is designed for the protection of personnel by sensing their presence on floor
areas around machinery and other similar hazards.

The system must be used only within the specification limits given and be installed strictly in
accordance with the information provided in this manual.

The system alone does not provide protection against hazards arising from the ejection of
materials, gasses and radiation. For these applications additional protective measures such as
physical guards may be required.

The system is not intended for use as a perimeter only guard.

The system is not intended for use as a machine initiation or re-initiation device. The
machine control circuit must be configured such that closing of the systems output contacts
enables the starting circuit of the machine but does not directly cause the machine to start up.
The starting or restarting of the machine should only be possible by a separate and deliberate
action at the designated machine controls.

The system is not suitable for use in explosive atmospheres.

If further guidance is required concerning the suitability of the system for a specific
application please contact supplier.

USE AS A COMBINED TRIP AND PRESENCE SENSING SYSTEM

Fig. 5 Use as a combined trip and presence sensing system.

The system allows a clear view of the process and unhindered access for operators and some types of
vehicles.

There must be sufficient space to allow the minimum distance from the hazard to the
accessible mat perimeter to be in accordance with safety distance calculations given in section
5.

The entire floor area between the defined perimeter and the hazard must be covered by mat
sensors so that it is not possible to approach or be in the vicinity of the hazard without
actuating the mat system.
