Reference Standards

An industrial remote control must be designed, built and used in compliance with legal requirements and technical regulations.
The standards are issued by the European Union.
Compliance with these standards is obligatory and demonstrated by CE marking on each component of the remote control.

 

The reference directive for all industrial remote controls, radio equipment and communication terminals is: R&TTE 1999/5/CE.

The purpose of this directive is to:

  • Determine the fundamental requirements for radio equipment, electromagnetic compatibility and electrical safety
  • Allow free trade within the EU without limits set by the approvals of individual member states
  • Inform manufacturers of their obligations and responsibilities

 

The R&TTE directive also refers to the following directives:

  • EMC Directive (2004/108/CE)
  • LVD Directive (2006/95/CE)

 

The reference directive for industrial machines and related safety components such as remote controls is 2006/42/EC.

The purpose of this directive is to:

  • Determine the fundamental safety and health protection requirements to be respected in designing and manufacturing to improve the level of safety for machines
  • The manufacturer or his agent must further ensure that a risk evaluation is performed for the machine that it intends to market. To that end, it must determine what are the fundamental safety and health protection requirements that can be applied to its machine and for which it must adopt provisions

Directives are applied by referring to the European standards: they, in turn, define the technical requirements that increase product safety and quality.

The reference standards are:

EN 300-220-2:        electromagnetic compatibility 25 MHz - 1GHz
EN 301-489-3:        electromagnetic compatibility 9 KHz - 40 GHz
EN 60950-1:           equipment for information technology and safety
EN 61000-6-2:        electromagnetic compatibility generic immunity standards
CEI-EN 50371:       human exposure to electromagnetic fields
EN 60204-32:         (lifting machines) machine electrical equipment
ISO 13849-1:          control systems linked to safety
UNI EN 13557:       (lifting machines) controls and control stations
UNI EN 13557:       functional safety of control systems
 

EN 300-220-2: Electromagnetic compatibility and questions related to the radio spectrum (ERM); Short Range Device (SRD)

Scope:

  • to establish the technical characteristics and testing methods for short range radio devices (SRD), in particular:
  • radiated radio power (ERP)
  • transient radio power
  • adjacent channel power
  • spurious emissions radiated from the transmitter
  • spurious emissions conducted from the transmitter
  • frequency stability under low voltage conditions
  • blocking or desensitization
  • spurious emissions radiated from the receiver
  • spurious emissions conducted from the receiver

 

EN 301-489-3: Electromagnetic compatibility and questions related to the radio spectrum (ERM); Short Range Device (SRD)

Scope:‚Äč

  • define the applicable inspection conditions and evaluate the performance and performance criteria for short range radio devices (SRD) and auxiliary equipment. In particular, the following are evaluated:
    • Radiated emissions
    • Conducted emissions
    • Harmonic current emissions
    • Voltage fluctuations and flicker

The devices are specifically subjected to:

  • RF electromagnetic fields (80-2000 MHz)
  • electrostatic discharges
  • fast transients
  • RF electromagnetic fields 0.15-80MHz
  • transistors and pulses
  • voltage drops and interruptions
  • line-line and line-earth pulses

 

EN 60950-1: Equipment for information technology - Safety Part 1: General requirements

Scope:

  • to specify the safety requirements to reduce the risk of fire, electrical shock and injury to operators and others who might come in contact with the equipment. The purpose of the standard is to reduce those risks with respect to installed equipment comprised of a system of interconnected or independent units provided that installation, operation and maintenance are performed in compliance with the manufacturer's requirements

 

EN 61000-6-2: EMC (electromagnetic compatibility) Part 6-2: Generic standards - Immunity for industrial environments

Scope:

  • applies to electrical and electronic equipment to be used in industrial environments and establishes the immunity requirements included in the frequency range of 0 Hz to 400 GHz

 

EN 60204-32: Electrical equipment of machines Part 32: Requirements for lifting machines

Scope:

contains the requirements and recommendations regarding electrical equipment of lifting machines in order to achieve:

  • the safety of people and property
  • consistency of responses to commands
  • ease of maintenance

 

EN 13849-1: Safety of machinery - Safety related parts of control systems. Part 1: general design principles

Scope:

  • to provide the safety requirements and guidance on the principles for the design and integration of the safety related parts of control systems (SRP / CS), including software design
  • to specify the characteristics which include the performance level (PL) required to carry out safety functions with a probabilistic approach

 

EN 13557: Lifting machines, Controls and control stations

Scope:

  • to specify the health and safety design requirements for controls and control stations for all types of lifting equipment

 

EN 62061: Safety of machinery - Functional safety of electrical electronic and programmable electronic control systems linked to safety

Scope:

  • to assign the safety integrity level (SIL) required for each control function related to it, to be achieved through SRECS (Safety Related Control System)
  • to allow the design of a SRECS suitable for the safety related function
  • to integrate the subsystems related to safety designed in compliance with ISO 13849
  • to validate the SRECS

 

RELIABILITY AND SAFETY ARE NOT THE SAME THINGS. 

SAFETY REQUIRES THE MAXIMUM PRIORITY INDEPENDENT OF THE RELIABILITY OBTAINED.
