Unit description

Gertebeschreibung

The unit meets the requirements of
EN 60947-5-1, EN 60204-1 and
VDE0113-1. In conjunction with a base
unit the unit is used as a

` Contact expansion module to in-

crease the number of contacts
available on a base unit. Base units
are all safety relays with feedback
loop monitoring.

` Pulse relay

– In accordance with

EN ISO 12100-1 and
EN ISO 12100-2 (inching circuit
for limited movement of hazard­ous machine components during
installation, set up and position­ing)

– in safety circuits in accordance

with VDE 0113 and EN 60204-1
(e.g. on movable guards)

` Safe timer relays

– in accordance with EN 1088 (re-

lease with delay through timer)

– in safety circuits in accordance

with VDE 0113-1 and EN 60204-

1 (e.g. on movable guards)
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.

` The unit can also be used without a

base unit as a pulse relay or safe
timer.

The unit is designed for use with

` Safety relays from the PNOZ X,

PNOZsigma, PNOZelog,
PNOZmulti series

` Safety gate monitors from the PST

series

` Two-hand relays from the

PNOZsigma, P2HZ series

Safety features

][Sicherheitseigenschaften_Kontakterweiterung_mit_RFK

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 is

detected.

` Earth fault in the input circuit:

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

Sicherheitseigenschaften Zusatz - Sicherung DC_PNOZ

` The unit has an electronic fuse.

Function description

Funktionsbeschreibung

` Delay-on de-energisation, not re-

triggerable
If the supply voltage at the input cir­cuit is interrupted, the safety con­tacts will open once the set release
time has elapsed, even if the safety
function is cancelled during the de­lay time. The unit cannot be reacti­vated until the delay time has
elapsed.

` Delay-on de-energisation, retrig-

gerable
(only possible as a standalone ap­plication or with the PNOZsigma
base unit!)
If the supply voltage at the input cir­cuit is interrupted, the safety con­tacts will open once the set release
time has elapsed.
If the safety function is cancelled
during the delay time (e.g. safety
gate closed), the unit will remain ac­tive.

` Pulse on switching on

The safety contacts close when
supply voltage is applied, the feed­back loop is closed and finally the
input circuit is closed. The safety
contacts are reopened once the
pulse time has elapsed.
If the input circuit is opened for
more than 10 ms during the pulse
time, the safety contacts will open

immediately and the auxiliary con­tact will be closed.

` Delay-on energisation

The set delay time is started when
supply voltage is applied, the feed­back loop is closed and finally the
input circuit is closed.
If the input circuit and feedback
loop are closed once the delay time
has elapsed, the safety contacts
will close and the auxiliary contact
will be opened.
If the input circuit is opened for
more than 10 ms, the safety con­tacts will open immediately and the
auxiliary contact will be closed.

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
