Unit description

Bestimmung/Gertebesc hreibung NOT-AUS , Schutzt, Lichtsc hr_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

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_nur_24_V_ACDC

` Single-channel operation (only with

24 VAC/DC): no redundancy in

U

B

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

][Funktionen_zweikanalig_ohne_quer

` Dual-channel operation without de-

tection of shorts across contacts:
redundant input circuit, detects
– earth faults in the reset and input

circuit,

– short circuits in the input circuit

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

][Funktionen_zweikanalig_mit_quer_manu

` Dual-channel operation with detec-

tion of shorts across contacts: re­dundant input circuit, detects
– earth faults in the reset and input

circuit,

– short circuits and shorts be-

tween contacts in the input cir­cuit.

][Funktionen_autoStart

` Automatic start: Unit is active once

the input circuit has been closed.

][Funktionen_manuStart

` Manual reset: Unit is active once

the input circuit is closed and then
the reset circuit is closed.

Please note:

` Information given in the “Technical

details” must be followed.

` Outputs 13-14, 23-24, 33-34, 43-

44, 53-54, 63-64 are safety con­tacts, outputs 71-72, 81-82, 91-92,
01-02 are auxiliary contacts (e.g. for
display).

` To prevent contact welding, a fuse

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