INFORMATION

This gives advice on applications and provides information on special fea-

tures.

Safety

Intended use

The safety relay provides a safety-related interruption of a safety circuit.

The safety relay meets the requirements of EN 60947-5-1, EN 60204-1 and VDE 0113-1

and may be used in applications with

}E-STOP pushbuttons

}Safety gates

The following is deemed improper use in particular:

}Any component, technical or electrical modification to the product

}Use of the product outside the areas described in this manual

}Use of the product outside the technical details (see Technical details [ 14]).

NOTICE

EMC-compliant electrical installation

The product is designed for use in an industrial environment. The product

may cause interference if installed in other environments. If installed in other

environments, measures should be taken to comply with the applicable

standards and directives for the respective installation site with regard to in-

terference.

Safety regulations

Safety assessment

Before using a unit it is necessary to perform a safety assessment in accordance with the

Machinery Directive.

Functional safety is guaranteed for the product as a single component. However, this does

not guarantee the functional safety of the overall plant/machine. In order to achieve the re-

quired safety level for the overall plant/machine, define the safety requirements for the

plant/machine and then define how these must be implemented from a technical and organ-

isational standpoint.

Use of qualified personnel

The products may only be assembled, installed, programmed, commissioned, operated,

maintained and decommissioned by competent persons.

PNOZ s1

Operating Manual PNOZ s1

21393-EN-08 7

A competent person is someone who, because of their training, experience and current pro-

fessional activity, has the specialist knowledge required to test, assess and operate the

work equipment, devices, systems, plant and machinery in accordance with the general

standards and guidelines for safety technology.

It is the company’s responsibility only to employ personnel who:

}Are familiar with the basic regulations concerning health and safety / accident preven-

tion

}Have read and understood the information provided in this description under "Safety"

}And have a good knowledge of the generic and specialist standards applicable to the

specific application.

Warranty and liability

All claims to warranty and liability will be rendered invalid if

}The product was used contrary to the purpose for which it is intended

}Damage can be attributed to not having followed the guidelines in the manual

}Operating personnel are not suitably qualified

}Any type of modification has been made (e.g. exchanging components on the PCB

boards, soldering work etc.).

Disposal

}In safety-related applications, please comply with the mission time TM in the safety-re-

lated characteristic data.

}When decommissioning, please comply with local regulations regarding the disposal of

electronic devices (e.g. Electrical and Electronic Equipment Act).

For your safety

The unit meets all the necessary conditions for safe operation. However, please note the

following:

}Note for overvoltage category III: If voltages higher than low voltage (>50 VAC or >120

VDC) are present on the unit, connected control elements and sensors must have a

rated insulation voltage of at least 250 V.

Function description

}Single-channel operation: No redundancy in the input circuit, earth faults in the start

and input circuit are detected.

}Automatic start: Unit is active once the input circuit has been closed.

}Manual start: Unit is active once the input circuit and the start circuit are closed.

}Increase in the number of available instantaneous safety contacts by connecting con-

tact expander modules or external contactors/relays;

A connector can be used to connect 1 PNOZsigma contact expander module.

Installation

Install base unit without contact expansion module:

}Ensure that the plug terminator is inserted at the side of the unit.

Connect base unit and PNOZsigma contact expansion module:

}Remove the plug terminator at the side of the base unit and at the contact expansion

module.

}Connect the base unit and the contact expansion module to the supplied connector be-

fore mounting the units to the DIN rail.

Installation in control cabinet

}The safety relay should be installed in a control cabinet with a protection type of at least

IP54.

}Use the notch on the rear of the unit to attach it to a DIN rail (35mm).

}When installed vertically: Secure the unit by using a fixing element (e.g. retaining

bracket or end angle).

}Push the device upwards or downwards before lifting it from the DIN rail.
