Unit description

Bestimmung/Gertebesch reibung Kontakter weiterungen Schalt _PNOZ

The unit meets the requirements of
EN 60947-5-1, EN 60204-1 and
VDE 0113-1. The contact expansion
module is used to increase the number
of instantaneous safety contacts avail­able on a base unit. Base units are all
safety relays with feedback loop mon­itoring.
The category that can be achieved in
accordance with EN 954-1 and
EN ISO 13849-1 depends on the cate­gory of the base unit. The contact ex­pansion module may not exceed this.

Safety features

Safety features

The unit meets the following safety re­quirements:

` The unit monitors its own output

contacts.

` The safety function remains effec-

tive in the case of a component fail­ure.

` Earth fault in the feedback loop:

Detected, depending on the base
unit that is used.

` Earth fault in the input circuit:

The output relays de-energise and
the safety contacts open.

Installation

][Montage_PNOZsigma Erweiterungsgert

Install contact expander module
without base unit:

` Ensure that the plug terminator is

inserted at the side of the unit.

Connect base unit and PNOZsigma
contact expander module:

` Remove the plug terminator at the

side of the base unit and at the con­tact expander module

` Connect the base unit and the con-

tact expander module to the sup­plied connector before 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 brakket or end angle).

` Push the unit upwards or down-

wards before lifting it from the DIN
rail.
