2 On safety

This chapter deals with your own safety and the safety of the equipment operators.

Please read this chapter carefully before starting to work with the UE4421 or with

machinery that utilizes the UE4421 as part of the machine safeguarding strategy.

2.1 Qualified safety personnel

The UE4421 and the components connected to it may only be assembled, operated and

maintained by qualified safety personnel. Qualified safety personnel are defined as

persons who …

 have undergone the appropriate technical training

and

 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 work 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

 have access to the operating instructions for the UE4421 Remote I/O bus node for

DeviceNet Safety (8011213) and have read them

and

 have access to the user manual Configuration System DeviceNet Safety (8011293) and

have read them

and

 have access to the operating instructions “DeviceNet Planning and Installation Manual”

of the Open DeviceNet Vendor Association (ODVA) (www.odva.org) and have read them

and

 have access to the installation and operating instructions for protective devices (e.g.

C4000 or S3000) connected to the UE4421 and have read them.

Prior to the installation of a UE4421, qualified safety personnel should conduct a risk

assessment on the machine to determine its suitability for the application.

2.2 Safety concept

The UE4421 devices have been third party certified as safety-rated devices in accordance

with the standards and testing criteria current at the time of certification. The safety tests

consist of test routines that run during all operating phases of the device.

Applicable standards include, but are not limited to, the following:

 EN ISO 13849@1 (UE4421 supports applications to performance level e).

 IEC 61508 (UE4421 supports applications to SIL3).

In general, the UE4421 requires that all safety-relevant input devices indicate a normal

run condition as an “ON” state. The “OFF” state is considered to be the safe state.

All safety capable inputs and safety capable outputs should be in failsafe state (e.g. inac-

tive (LOW) state) during any fault or safety trip condition.

On safety

2.2.1 Functional safety per IEC 61508

Functional safety of electrical/electronic/programmable electronic (E/E/PE) safety-related

devices is now guided by international standard IEC 61508. Use of these devices involves

identifying specific hazardous conditions that may lead to serious consequences and then

establishing the maximum tolerable frequency.

IEC 61508 defines functional safety integrity targets for the maximum tolerable failure

rate for each piece of equipment, based on that equipment’s relative contribution to the

hazard being considered. These “safety integrity levels” (SIL) fall into two classifications:

Low demand mode of operation and high demand mode of operation. The following table

defines the SIL levels for high demand mode of operation.

Safety Integrity Level High Demand Mode of Operation

The UE4421 is certified as meeting SIL3 requirements in accordance with IEC 61508.

2.2.2 Risk assessment

A risk assessment must be completed in order to determine the tasks and hazards asso-

ciated with a machine and what methods are utilized to reduce or eliminate the hazards

associated with each task. Standards and technical reports that describe the process of

risk assessment include, but are not limited to, the following:

 EN ISO 14121@1

 ANSI/RIA R15.06

 ANSI B11.TR3

Risk assessment is an iterative process. Once tasks and hazards have been identified and

a risk has been determined, the process of risk reduction begins. This entails the selec-

tion, installation and integration of safeguards to mitigate the hazard. After installation and

integration of these safeguards, the next step is to perform a subsequent risk assessment

based on the changes. Additional risk reduction may be necessary for any residual risks

that may exist.

Performance of risk assessment is necessary!

Consult your local, regional and national regulations, standards and technical reports for

additional details regarding the performance of risk assessment and implementation of

risk reduction requirements.

The proper use of the safety device described in this operation manual as it relates to in-

stallation conditions and mechanical performance and functions is a prerequisite for its

use. When selecting or using this safety device, risk assessment must be conducted with

the aim of identifying potential danger factors in equipment or facilities in which the safety

device is to be applied, during the development stage of the equipment or facilities. Suit-

able safety devices must be selected under the guidance of a sufficient risk assessment

system. An insufficient risk assessment system may lead to the selection of unsuitable

safety devices.

On safety

2.2.3 Hardware configuration

 To ensure safety-rated operation, use only SICK configuration files (.EDS files) in

conjunction with the corresponding SICK safety-rated device.

 Follow the specifications outlined in these operating instructions.

 Only equipment that can be isolated safely from the main power source should be

connected to the system.

Only use safety-relevant hardware and software for safety-relevant applications!

Hardware modules and software components that are not safety-rated may be used to

process non-safety-rated signals and monitor (only) safety-rated signals. However, these

devices cannot be used to carry out safety-related task processing.

2.2.4 Programming requirements

It is imperative that only safety-relevant signals from the UE4421 are utilized for safety-

relevant logic. Since the UE4421 cannot determine whether standard devices or safety-

relevant devices have been connected to the UE4421, the user of the device(s) (e.g. OEM,

integrator or end-user) must be sure that the signals used in any safety-relevant control

strategy are appropriate and correct.

For configuration of the UE4400, utilize the Electronic Data Sheet (EDS) file provided with

SICK DeviceNet Safety Configurator. If you do not have SICK DeviceNet Safety Configura-

tor, the latest .EDS file may be downloaded from the ODVA website at

http://www.odva.org

You are responsible for programming your control system correctly in accordance with

these instructions, applicable regulations and standards!

Since the UE4421 and associated components are programmable devices, the user is

responsible for assuring that the UE4421 and any associated device is programmed

properly and suitable for the application. SICK shall not be responsible for the user’s

programming of any programmable product, or any consequence thereof.

2.2.5 Communication

The UE4421 communicates via DeviceNet and DeviceNet Safety via the five-pole terminal

block located on the front of the unit. UE4421 is configured using a DeviceNet connection

via a Safety Network Configuration Tool (SNCT; e.g. SICK DeviceNet Safety Configurator

with Safety Extensions).

2.2.6 Response time

It is imperative that all safeguarding devices be installed and integrated into the safety

control system to prevent access to all hazards. A key factor in determining device location

is the minimum safety distance.

Formulas that describe minimum safety distance vary based on device type, safeguard

orientation, resolution, system response time, and more. Consult applicable machine

regulations and standards for information regarding safeguarding device installation and

integration requirements.

The response time associated with the UE4421 is described later in this document.

ty-rated Originator. The UE4421 may also be used as a DeviceNet slave device in connec-

tion with a third-party DeviceNet master device/controller.

Signals generated by any device must be suitable for the application logic.

Since non-safety-rated devices can be connected to the safety capable inputs or safety

capable outputs of the UE4421, it is imperative that

 all input signals are suitable for the application, e.g. safety devices are connected to

safety capable input signals in safety relevant applications

and

 all output signals are suitable for the application e.g. safety devices are connected to

safety capable outputs in safety relevant applications

Control logic that utilizes information from the UE4421 must consider whether these

devices are suitable for the application. Safety devices should satisfy the rating required

for the application (e.g. a type 4 safety light curtain should be installed and integrated to

satisfy type 4 machine safeguarding requirements).

The installation and integration of devices on the UE4421 must meet regulatory

requirements!

The UE4421 supports applications up to SIL3 in accordance with IEC 61508 and up to

Performance Level e in accordance with EN ISO 13849@1.

However, the user is responsible for insuring that all devices connected to the UE4421 are

suitable for their intended purpose and that the logic, wiring, installation and integration

(including configuration, etc.) of these devices is in accordance with the application

requirements, regulations (including local, regional and national) and standards.

2.3.1 Additional precautions according to UL 1604

Models UE4421@22EE900 and UE4421@22EE490 are suitable for use in Class I, Div. 2,

Group A, B, C, D or non-hazardous location only.

2.4.2 Compliance with EMC directive

SICK industrial safety devices are designed for local DC supply applications only!

Machines where safety devices are used must be installed and designed according to the

Lightning Protection Zone (LPZ) EN 62305@1. Required immunity levels can be achieved

through the use of external protective devices. The installed surge protective devices (SPD)

should meet the requirements of EN 61643@11.

T

he installation must prevent disturbances according to IEC 61000@4@16 (common mode

disturbances in the frequency range of 0 Hz to 150 kHz).

The UE4421 complies with the relevant EMC standards so that it can be easily integrated

into the overall machine control system. The user, however, must confirm overall system

conformance. Conditions vary based on configuration, wiring and other conditions of the

equipment or control panel that the UE4421 is installed in. The user is therefore responsi-

ble for performance of the final check to confirm that devices and the overall machine

conform to EMC standards.

2.4.3 Compliance with Low Voltage Directive

Always ensure that devices operating at voltages of 50 V AC to 1000 V AC and 75 V DC to

1500 V DC meet the necessary safety standards for the Controller (EN 61131@2).

2.4.4 Compliance with EC directives

DeviceNet products that comply with EC directives must be installed as follows:

 All UE4421 devices must be installed within control panels rated IP 54 minimum.

 Satisfy the power supply requirements outlined in section 5.2 “Power supply

requirements” on page 57 of this manual.

 The UE4421 also conforms to the Common Emission Standard (EN 50081@2). Radiated

emission characteristics (10-m regulations) may vary depending on the configuration of

the control panel used, other devices connected to the control panel, wiring and other

conditions. You are responsible for confirming that the overall machine or equipment

conforms to EC directives.

2.4.5 Reducing noise

The following examples show how to reduce noise.

 Reduce electrical noise from the communication cable by installing a ferrite core on the

communication cable within 10 cm (3.93 in) of the DeviceNet Master unit or the

DeviceNet Safety Originator unit. The following model is suitable:

– Ferrite Core (Data Line Filter) LF130B manufactured by Easy Magnet Company

 Wire the control panel with cables that are as short as possible and ground to 100  or

less.

 Keep DeviceNet communication cables as short as possible and ground to 100  or
