Unit description

Bestimmung/G erätebeschr eibung NOT -AUS, Schutz t, Lichtsch r_PNOZ

The safety relay meets the require­ments of EN 60947-5-1, EN 60204-1
and VDE 0113-1 and may be used in
applications with

 E-STOP pushbuttons
 Safety gates
 Light beam devices

Bestimmung/G erätebesch reibung_Ka tegorie_PN OZ

The max. category the safety contacts
can achieve in accordance with
EN 954-1 and EN ISO 13849-1 is stat­ed in the technical details.

Safety features

][Sicherheitseigenscha ften Schaltgerät_allgem einer Teil

The relay meets the following safety
requirements:

 The circuit is redundant with built-in

self-monitoring.

 The safety function remains effec-

tive in the case of a component fail­ure.

 The correct opening and closing of

the safety function relays is tested
automatically in each on-off cycle.

Sicherheitseigenschaften Zusatz - AC/DC-Gerte_PNOZ

 The tranformer is short circuit-

proof. An electronic fuse is used on
a DC supply.

Function description

][Funktionen_einkanalig

 Single-channel operation: no re-

dundancy in the input circuit, earth
faults in the reset and input circuit
are detected.

][Funktionen_zweikanalig_mit_quer_ber

 Dual-channel operation with detec-

tion of shorts across contacts: re­dundant input circuit, detects

Timing diagram

– earth faults in the reset and input

circuit,

– short circuits in the input circuit

and, with a monitored reset, in
the reset circuit too,

– shorts between contacts in the

input circuit.

][Funktionen_autoStart

 Automatic start: Unit is active once

the input circuit has been closed.

][Zeitdiagramm_auto_ueber2_del

][Funktionen_berStart_Wartezeit

 Monitored reset: Unit is active once

the input circuit is closed and once
the reset circuit is closed after the
waiting period has elapsed
(see technical details).

][Funktionen_Kontaktvervielfachung

 Increase in the number of available

instantaneous safety contacts by
connecting contact expansion
modules or external contactors.

Please note:

 Information given in the “Technical

details” must be followed.

 Outputs 13-14, 23-24, 33-34 are in-

stantaneous safety contacts, out­puts 47-48, 57-58 are delay-on de­energisation safety contacts.

 To prevent contact welding, a fuse

should be connected before the
output contacts (see technical de­tails).

 Calculation of the max. cable runs
