erence.

1.3 Definition of symbols

Information that is particularly important is identified as follows:

DANGER!

This warning must be heeded! It warns of a hazardous situation that poses

an immediate threat of serious injury and death and indicates preventive

measures that can be taken.

WARNING!

This warning must be heeded! It warns of a hazardous situation that could

lead to serious injury and death and indicates preventive measures that can

be taken.

CAUTION!

This refers to a hazard that can lead to a less serious or minor injury plus

material damage, and also provides information on preventive measures

that can be taken.

NOTICE

This describes a situation in which the product or devices could be dam-

aged and also provides information on preventive measures that can be

taken. It also highlights areas within the text that are of particular import-

ance.

3 Safety

3.1 Intended use

The expansion module monitors standstill, speed and direction of rotation in accordance

with EN ISO 13849-1 up to PL e and EN IEC 62061 up to SIL CL 3.

The expansion module may only be connected to a base unit from the PNOZmulti system

(please refer to the document "PNOZmulti System Expansion" for details of the base units

that can be connected).

The configurable small control systems PNOZmulti are used for the safety-related interrup-

tion of safety circuits and are designed for use in:

}E-STOP equipment

}Safety circuits in accordance with VDE0113 Part 1 and EN60204-1

WARNING!

Users must take appropriate measures to detect or exclude errors (e.g. slip-

page or broken shearpin) which cause the frequency of the encoder signal

to no longer be proportional to the monitored speed.

Appropriate measures are:

– Using the monitored encoder to also control the drive

– Mechanical solutions

– Monitoring for broken shearpin by means of the speed monitor

WARNING!

A single-channel open circuit/input device error is recognised and leads to a

safe condition of the outputs at the relevant axis.

For applications in accordance with PL e and SIL CL 3, the "Overspeed"

output must be integrated into the safety function in every operating mode

and evaluated so that a shutdown occurs if the output switches to a safe

condition ("Overspeed" output = "0").

Safety

Operating Manual PNOZ ms2p HTL

1001401-EN-04 10

CAUTION!

If there are frequency differences between tracks A and B of the incre-

mental encoder and/or between the proximity switches on inputs I10 (I20)

and I11 (I21), the PNOZmulti switches to a safe state if a frequency ex-

ceeds the configured standstill frequency and is greater than 2 Hz. If the

speed monitor detects different directions of rotation, please note:

– With version 1.X devices the PNOZmulti changes to STOP.

– With devices from version 2.0, the axis in question switches to a safe

condition. The safe condition is cleared again as soon as the error is

remedied. Hazards that can arise through an automatic restart must

be excluded within the user program.

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 [ 29]).

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.

3.2 System requirements

Please refer to the "Product Modifications PNOZmulti" document in the "Version overview"

section for details of which versions of the base unit and PNOZmulti Configurator can be

used for this product.
