3 Safety

3.1Intended 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 modular safety system.

The modular safety system PNOZmulti is used for the safety-related interruption of safety circuits and is designed for use on:

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. slippage 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").

3 Safety

3.1Intended use

CAUTION!

If there are frequency differences between tracks A and B of the incremental encoder and/or between the proximity switches on inputs I10 (I20) and I11 (I21), the PNOZmulti switches to a safe condition if a frequency exceeds the configured standstill frequency. If the speed monitor detects different rotation directions, note the following:

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.

3.1.1System requirements

Please refer to the "Product Modifications" document in the "Version overview" section for details of which versions of the base unit and PNOZmulti Configurator can be used for this product.
