The expansion module monitors standstill, speed and direction of rota-

tion up to Category 3 of EN 954-1.

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

PNOZmulti modular safety system.

The PNOZmulti modular safety system is used for the safety-related in-

terruption of safety circuits and is designed for use on:

` Emergency 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 fre-

quency of the encoder signal to no longer be proportional to the

monitored speed.

Appropriate measures are:

` Use of the input device to be monitored also for drive control-

ling

` 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 safe condition of outputs at the relevant axis.

For applications according to category 3, the "Overspeed" out-

put must be integrated into the safety function in every operat-

ing mode and evaluated so that a shutdown occurs if the output

switches to a safe condition ("Overspeed" output = "0").
